[00:27:54] <generic_nick|2> thanks JT-Shop-2
[00:27:55] <Aero-Tec> if the lathe works for feed per rev, would it be setup for threading?
[00:28:02] <generic_nick|2> might be a bit of a drive lol
[00:28:21] <generic_nick|2> not neccesarily Aero-Tec
[00:28:37] <generic_nick|2> you can do feed/rev without a spindle encoder
[00:28:38] <Aero-Tec> The pins motion.spindle-at-speed and the encoder.n.phase-Z for the spindle must be connected in your HAL file before G76 will work. See the Integrators Manual for more information on spindle synchronized motion.
[00:28:51] <Aero-Tec> how do I make sure this is set up?
[00:29:00] <generic_nick|2> do you have a spindle encoder?
[00:29:07] <Aero-Tec> is there a quick test?
[00:29:28] <generic_nick|2> i dunno, look for one? lol
[00:29:29] <Aero-Tec> one pulse per rev encoder
[00:29:55] <Aero-Tec> so it is index and encoder
[00:29:58] <generic_nick|2> i think you need more than 1 pulse per rev to actually thread
[00:30:14] <Aero-Tec> hope that is not true
[00:30:37] <Aero-Tec> with have a ton of work to do
[00:30:44] <Aero-Tec> will
[00:31:12] <generic_nick|2> i may be wrong, but i cant imagine the threads will be all that hot with 1 pulse per rev. maybe one of the smart guys will chime in
[00:32:32] <ssi> I was hoping I wouldn't have to rebuild these belt drives :/
[00:32:53] <Aero-Tec> will find a threading example and try it I guess
[00:35:43] <generic_nick|2> just got my mill stripped the rest of the way. down to the base now. hopefully my cherry picker will hold together long enough to get it on my friend's trailer.
[00:37:02] <gabewillen> So can rt_mutex_give only be used from realtime modules?

[00:58:57] <PetefromTn> altho the screw in style might be more secure actually
[00:59:32] <Aero-Tec> looks like the threading works
[00:59:47] <Aero-Tec> did not cut a thread but did cut air
[01:00:31] <Aero-Tec> amount per rev works and the lathe cut air, I am hoping that is all the testing needed
[01:00:51] <Aero-Tec> might cut a test thread just to make sure

[02:09:03] <ssi> so no motion out of the G540 via the 5i25 for some reason :/
[02:09:14] <ssi> if I connect directly to the parport, stepconf test works
[02:09:39] <skunkworks> ssi: you flashed it with the correct firmware?

[02:10:14] <ssi> pinouts in dmesg are correct
[02:10:21] <ssi> charge pump not working either, but I disabled it

[03:09:56] -!- tmcw has quit [Ping timeout: 252 seconds]
[03:11:02] <jdh> get a simple schematic, run it through there, see what happens.
[03:11:08] <RootB> i got a g-code
[03:11:13] <RootB> i have no available computers
[03:11:17] <RootB> to connect my CNC right now
[03:11:37] <jdh> then I have know idea what you are asking.
[03:12:41] <Tom_itx> or why
[03:13:18] <jdh> yeah, well... that too.
[03:13:27] <jdh> you want someone to run your gcode?
[03:14:10] <ssi> skunkworks: not yet
[03:14:21] <ssi> pcw_home: crazy question... is the DB25 on card P2 or P3?
[03:14:36] <ssi> cause I wonder if the stepgens might just be attached to the wrong pins
[03:15:08] <jdh> did you read page 4 of the manual?
[03:15:22] <ssi> looking at it now
[03:15:25] <ssi> and I guess that's not it
[03:16:05] <jdh> The default is to disable the pull-ups To enable the built-in pull-ups,
[03:16:06] <jdh> (the default condition) jumper W4 should be placed in the UP position
[03:16:31] <jdh> so, what is the default?
[03:16:49] <ssi> eh?
[03:17:30] <pcw_home> First stepgens are on P3
[03:17:51] <pcw_home> (DB25)
[03:17:55] <ssi> right

[03:20:45] <ssi> ok so it works
[03:20:46] <ssi> rub it in ;)
[03:21:34] <a1cypher> Hey folks. I'm just starting to use emc2 after having used Mach3. One question I had is that every time I exit emc2 and start it back up again, it looses its "home". If I look at the DRO the coordinates seem to be correct, but theres a but it wont let me touch off because it has the axes set as unhomed. Any ideas how I can just tell it that the current coords are correct and to set it as homed ?
[03:22:06] <jdh> you can disable the homing requirement
[03:22:27] <a1cypher> Is that in the .ini file somewheres ?
[03:23:39] <jdh> yeah, there is a nice section in teh docs about limits and homing, but I don't see them offhand
[03:23:52] -!- nathanstenzel [[email protected]] has joined #linuxcnc
[03:24:00] <a1cypher> is it this per chance?
http://www.linuxcnc.org/docs/2.4/html/config_ini_homing.html
[03:24:22] <jdh> looks good to me.
[03:24:45] <nathanstenzel> anyone have opinions on the qu bd rapid prototyping machine which is supposed to do 3d printing and milling of even steel?
[03:24:48] <a1cypher> My "homing" doesnt seem to work right now anyways. When I click home it just sets the axis to 0, so to home I have to manually drive it into the limit switch, then back off and set home.
[03:25:13] <jdh> if you start at the top with the home configs, you should be able to get it to work.
[03:25:27] <jdh> but, I thought there was an option to just not force homing
[03:26:02] <jdh> NO_FORCE_HOMING = 1
[03:26:22] <jdh> goes in the [TRAJ] section
[03:26:28] -!- Gamma-x [[email protected]] has joined #linuxcnc
[03:26:52] <a1cypher> but I can still home if I want, right.
[03:26:55] <jdh> probably better to make your homing work
[03:27:38] <a1cypher> well, I will do that too, but what I want is to be able to shutdown and then start up again and pick up where I left off without screwing up the machine coords.
[03:27:48] <jdh> steppers?
[03:27:51] <a1cypher> yeah.
[03:28:05] <jdh> you will probably move to the nearest whole step
[03:28:56] <jdh> but a normal home switch is probably less accurate than being off 1 step
[03:29:07] <Tom_itx> a1cypher,
http://www.gnipsel.com/linuxcnc/g-code/index.html
[03:29:21] <Tom_itx> look at tool touchoff and fixture offsets
[03:29:28] <a1cypher> k.. will do
[03:29:33] <Tom_itx> or the whole thing
[03:29:33] <r00t4rd3d> a1cypher, i do what you want all the time
[03:29:43] <r00t4rd3d> shut down and start later with no homing switches
[03:30:03] <a1cypher> r00t4rd3d: do you do that by setting NO_FORCE_HOMING ?
[03:30:09] <r00t4rd3d> yeah
[03:30:24] <a1cypher> I think for most of what I do, I dont care if its off by 1 step.
[03:30:34] <r00t4rd3d> i only cut wood
[03:31:15] <jdh> http://www.linuxcnc.org/docs/devel/html/config/ini_config.html
[03:31:20] <jdh> has all the ini options
[03:31:25] <a1cypher> 1 step on my machine I think will work out to be like 1/4 mil or something like that.
[03:32:38] <a1cypher> yeah, I think thats the option I want. I dont care about the soft limits anyways since I have limit switches.
[03:32:43] <r00t4rd3d> you can use the MDI tab and enter g28 x0
[03:32:55] <r00t4rd3d> or g28 y0 to send the axis back to where you started
[03:33:24] -!- Nick001 has quit [Ping timeout: 256 seconds]
[03:33:31] <jdh> you can?
[03:33:44] <r00t4rd3d> yeah
[03:33:49] <jdh> after you store them
[03:34:06] <ssi> if you have limit switches, why not just set them up as home switches and home the machine?
[03:34:24] <r00t4rd3d> i dont use any switches
[03:34:43] <jdh> I have no_force_home on one of mine, it complains if I don't home (axis exceeds limit)
[03:34:54] <a1cypher> ssi: I will, but my limit switches are less accurate than my stepper. So by rehoming I may no longer be completely aligned with my work that has been partially done.
[03:35:38] <ssi> aha
[03:35:48] <a1cypher> I will have to experiment to see if I rehome if it can return to the exact same spot every time.
[03:35:57] <ssi> yea on my small lathe i've thought about adding encoders to the steppers just for the home on index feature
[03:35:59] <a1cypher> maybe If I home really slow for the last bit
[03:36:00] <r00t4rd3d> sometimes when setting my z height i will press my bit into the wood a touch to make a indent so I know where I started
[03:36:39] <a1cypher> the z height is the main thing I dont want to loose. I use engraving bits and I have to carefully set the height exactly. If I re-home I may loose that offset
[03:37:03] <a1cypher> especially when milling PCBs and then the z-height may need to be ~0.5mil accurate
[03:37:05] <r00t4rd3d> make a touch off plate
[03:37:21] <a1cypher> probably a good idea

[04:09:41] <ssi> yeah I do that too
[04:09:53] <chopper791> I have done so many configs for mills and routers, but plasma = beer

[04:15:26] <chopper791> I have went through the entire 5i20 config that comes with linuxcnc and I see no reference to the subroutine there. This makes me think that the sub is in the post processor. Just can not open the file for some reason
[04:15:38] <chopper791> nathan-2 machines for sure

[04:19:36] <chopper791> my x and y are spot on also, but thc to control z = not so much right now

[04:27:16] <ssi> I'm at 20 and it's slower than I'd like
[04:27:23] <pcw_home> If you get following errors you probably are violating timing (step time step space stepgen maxvel stepgen maxaccel)
[04:27:23] -!- mhaberler has quit [Quit: mhaberler]
[04:27:43] <chopper791> interesting as my table is very snappy
[04:28:20] <pcw_home> stepgen maxaccel needs to be about 25% more than machine maxaccel
[04:28:45] <Gamma-x> im getting stepper errors.... as in ... they wont move just buzz realy loudly...
[04:29:05] <chopper791> pcw-yeah I have noticed that and have been messing around with different percentages and taking notes on the results. Why is it like that?
[04:29:59] <ssi> pcw_home: yea that helps a lot
[04:30:03] <ssi> at 1200ipm and 40i/s/s now
[04:30:13] <chopper791> Gamma if they dont move and they just buzz like that then make sure your steps/unit are correct and turn down the accel and velocity a bit
[04:30:26] <ssi> that,s worlds faster than mach could ever run it
[04:30:31] <chopper791> It sounds like your setting are a bit off for your machine setup
[04:30:57] <Gamma-x> chopper791, it can happen with low vel and accel... steps/unit? you mean steps per rev? its set at 200 as there 1.8 degree motors.
[04:31:08] <chopper791> I cant stand mach. 90% of my tech calls are for mach issues
[04:31:32] <chopper791> What step mode are you in gamma?
[04:31:45] <ssi> there's 1800ipm
[04:31:50] <Gamma-x> the driver I have is a leadshine ma860h
[04:31:58] <chopper791> What kind of drive system ssi?

[04:32:24] <ssi> and 60i/s/s
[04:32:26] <chopper791> Gamma- what step mode do you have the drivers set i
[04:32:29] <ssi> chopper791: rack and pinion
[04:32:39] <ssi> 280oz steppers driving a 1" pinion through a 3:1 reduction
[04:32:39] <chopper791> nice-ssi...... gearing?
[04:33:24] <chopper791> Gamma if you are set for 400 pulses on the driver then you are in half step. Are you at 400 pulses?
[04:33:47] <ssi> aw nuts... so my pseudo-slaved Y almost works... the motors run the same direction.. they need to be backward to each other
[04:33:53] <ssi> can I do thta by rewiring the motor?
[04:34:04] <Gamma-x> chopper791, driver is set at microstepping of 2
[04:34:14] <chopper791> Are you slaved on outputs ssi?
[04:34:17] <pcw_home> invert the direction bit
[04:34:28] <ssi> pcw_home: oh on the stepgen?
[04:34:29] <ssi> awesome
[04:34:43] <chopper791> so you are using the A port for your slave ssi?
[04:34:46] <pcw_home> on the appropriate GPIO
[04:35:14] <ssi> pcw_home: I don't follow exactly
[04:35:23] <ssi> you mean the gpio that would be stepgen 3's dir pin?
[04:35:33] <pcw_home> yep
[04:35:36] <chopper791> Gamma if your setting is at two on the driver then you are in full step correct?
[04:35:46] -!- dhoovie [[email protected]] has joined #linuxcnc
[04:35:58] <chopper791> 200 pulses?

[04:36:11] <ssi> I can just invert gpio 012?
[04:36:25] <Gamma-x> chopper791,
http://leadshineusa.com/Product_Show.aspx?ID=123
[04:37:02] <pcw_home> Yes you setp the invert_output attribute
[04:37:04] <chopper791> Yeah your in 1/2 step
[04:37:07] <chopper791> gamma
[04:37:16] <Gamma-x> yeah
[04:37:27] <ssi> neat
[04:37:28] <ssi> works
[04:37:35] <chopper791> Gamma are you using lead screws?
[04:37:43] <Gamma-x> chopper791, ball
[04:37:48] <chopper791> whats the TPI
[04:37:55] <Gamma-x> 5
[04:38:03] <chopper791> mm or inch
[04:38:11] <Gamma-x> its actually like 5.01 or something...
[04:38:12] <Gamma-x> inches
[04:39:37] <chopper791> so take 200 (steps per revolution on motor) x 2 (1/2 step on driver) x 5.01 (TPI of screw) = 2004 steps per unit is what your axis config screen should say at the bottom if your using step config
[04:40:26] <chopper791> In step config you will have 200 steps per revolution, 2 for the microstep mode, and 5.01 for the lead screw
[04:40:47] <Gamma-x> im pretty sure it says 1000
[04:40:56] <Gamma-x> microstep mode is .5
[04:41:03] <chopper791> Thats part of the problem then
[04:41:21] <chopper791> Change the microstep in the axis setup to 2
[04:41:28] <Gamma-x> when it is in 2 im almost certain it does not work at all..
[04:41:40] <ssi> this thing moves so fast now it's scary
[04:41:59] <Gamma-x> although i may have had accel/ up too high
[04:42:44] <chopper791> Then you have a few things going on (1) Velocity and accel are to high, (2) You have mechanical issues (3) motors and drivers are sized to small for machine.
[04:42:47] <ssi> I don't think the Y axis is quite happy at 1500ipm
[04:43:03] <chopper791> may have a few things going on I should say
[04:43:32] <Gamma-x> chopper791, plausible...
[04:43:50] <Gamma-x> thaqnks!
[04:44:08] <chopper791> Steppers have more torque in lower RPM ranges so if the problem goes away at slower speeds then it helps norrow it down

[04:47:36] <chopper791> When I generate the code in sheetcam and try loading it I get the error of can not open file <touchoff> which is a subroutine file. I have the file in my NC folder and there is no reference to placing it anywhere else. Stumped on this

[06:46:45] <chopper791> Anybody on?
[06:48:16] <Gamma-x> me
[06:50:30] <archivist> in irc ask the real questions
[06:51:23] <chopper791> Need some help with an input signal. I need to invert the my parport.1.pin-10-in as its seeing the signal reversed for some reason.I have tried using an invert but startup errors out and says parport.1.10-in is not found
[06:51:29] <Gamma-x> anyone know the correct terminology for the tormach draw bar pneumatic cylinders?
[06:51:53] <chopper791> Sorry I figured I would see if anybody was on before I started typing.
[06:51:58] <Gamma-x> chopper791, what is pin 10?
[06:52:50] <chopper791> pin 10 is my arc ok input pin. The thc moves my z axis when the arc is ok and keep does not move it when the arc is not ok
[06:53:24] <Gamma-x> arc? keep?
[06:53:30] <Gamma-x> dunno those terms
[06:53:38] <chopper791> I have used a -not on the pin and it shows the same results so I figure I would have to invert the signal like a spindle
[06:53:45] <chopper791> arc = plasma arc ok
[06:54:26] <chopper791> keep was not supposed to be there
[06:54:45] <Gamma-x> ohhh
[06:55:54] <chopper791> The issue is if I use a parport.1.pin10-in-invert 1 I receive an error on start up saying parport.1.pin10-in is not found
[06:56:16] <Gamma-x> is it grounded?
[06:56:28] <archivist> use the right name
[06:56:42] <chopper791> what name is that archivist
[06:56:55] <archivist> or create it by using an invert comp (not)
[06:57:40] <chopper791> Not following you on that. Please explain
[06:58:18] <chopper791> setp parport.1.pin-10-in-invert 1 should this invert the signal?
[07:01:17] <Valen> you should just mix negative logic into your code
[07:01:24] <Valen> just to keep you on your toes later on
[07:03:02] <chopper791> Please forgive me but Im kinda new to this
[07:03:25] <Valen> chopper791, don't do what I said, I was being sarcastic ;->
[07:03:37] <chopper791> fair enough
[07:03:54] <chopper791> ;-)
[07:04:36] <chopper791> Am I even able to invert this input signal?
[07:05:26] <archivist> yes
[07:05:52] <chopper791> Does it seem like this is what I need to do before I go at it?
[07:05:53] <archivist> the key word is not which is an inversion
[07:10:11] <chopper791> SO if I was to invert this signal and using setp parport.1.pin-10-in-invert 1 does not do it then how would you suggest go about doing this task?
[07:11:47] <archivist> http://linuxcnc.org/docs/html/hal/components.html#_logic_and_bitwise_components_a_id_sec_realtime_components_logic_a
[07:12:44] <archivist> or you look at the component pins and choose the right name if it has one
[07:13:28] <chopper791> net thc-arc-ok thcud.arc-ok <= motion.digital-in-00 <= parport.1.pin-10-in-not
[07:13:45] <chopper791> using a not or not using a not does not work. Is this what you mean?
[07:14:26] -!- ler_hydra [[email protected]] has joined #linuxcnc
[07:15:02] <chopper791> I know that pin 10 is there as my thc uses it fine. Its the logic I guess I would say is reversed.
[07:16:21] <chopper791> When ARC is OK the THC does not move the Z axis, when ARC is not OK the thc will move the z axis
[07:16:41] <archivist> if that is what you want
[07:17:11] <chopper791> sorry when ARC is ok the thc will move the z axis and when the ARC is not OK the thc will not move the z axis
[07:17:39] <RootB> ok linuxCNC
[07:17:42] <chopper791> this should be reversed
[07:17:48] <RootB> im having plenty of trouble with PCBG-Code
[07:20:03] <archivist> chopper79, parport.1.pin-10-in-not is the inverse of parport.1.pin-10-in it is why I have been pointing you at the NOT keyword
[07:20:55] <chopper791> This does not work though
[07:21:04] <chopper791> This was the first thing I tried
[07:21:20] <chopper791> Next was using an invert
[07:21:43] <archivist> not IS and inversion how many times do I have to say that
[07:22:32] <chopper791> Well just once as have used NOT many times before and this time it does not work for me.
[07:23:15] <chopper791> Like I said using a NOT was the first thing I tried and had no results
[07:24:02] <archivist> "does not work" is not a proper statement of a problem, people need a better explanation of the fault
[07:24:38] <chopper791> so how should I explain it then?
[07:29:16] <chopper791> regardless, if I use a NOT or leave NOT out the signal still never inverts.
[07:29:29] <archivist> you could pastebin your hal and ini files, or you could do some diagnosis as to why things are not happening as you expect
[07:30:01] <archivist> not does invert prove it
[07:30:29] <archivist> use halscope
[07:30:51] <archivist> and a real scope on the wire
[07:31:21] <archivist> this is the diagnosis part
[07:32:40] <archivist> do you have a pull up resister to make sure the signal goes high
[07:32:56] <chopper791> I am not denying that the signal does not invert as halscope shows that. The issue is regardless if I use NOT or leave it out, the function of the THC remains the same. I have been diagnosing this issue and now I am seeking help as to why the issue remains after trying multiple different approaches.
[07:33:38] <chopper791> I thought about a pull up resistor but wanted to try without one first.
[07:34:19] -!- Patang has quit [Ping timeout: 260 seconds]
[07:34:51] <chopper791> I figured that if the signal is working, but just in reverse that I should be bale to do a simple invert and correct it. I guess I am wrong on this.
[07:35:28] <chopper791> The pull resistor up does make sense though so I will give it a shot
[07:36:21] <RootB> Hey linuxCNC
[07:36:26] <RootB> Could you help me out with milling my first PCB?
[07:36:30] <RootB> I can't seem to be able to.
[07:36:59] <archivist> RootB, we are not seeing questions we can answer yet
[07:38:39] <RootB> I really don't have an idea how to set up the coordinates, depth gap and all that
[07:39:09] <archivist> experiment and learn
[07:39:34] <archivist> and it is tooling related too
[07:56:48] <RootB> I'm using V-shaped endbits
[07:56:55] <RootB> But i can't seem to get the depthness right.
[07:56:58] <RootB> If i put too much
[07:57:02] <RootB> It pierces thru the cooper
[07:57:11] <RootB> if i put it just touching the copper, it doesnt even scratch!

[13:29:28] <gabewillen> should of known better

[13:29:53] <cradek> it's not a slap, it's a clear and concise pointer to the information you need :-)
[13:29:54] <gabewillen> thank you
[13:29:59] <cradek> anytime
[13:30:11] <gabewillen> no not by you, just i feel like an idiot, its clear as day written in there
[13:30:31] <cradek> probably rtapi_mutex_get should be a symlink to rtapi_mutex, but it isn't
[13:30:49] <cradek> because it took me two tries to find the manpage
[13:30:56] <cradek> bbl
[13:32:24] <gabewillen> the reason i ask is that i have wrapped liblinuxcnchal using python ctypes
[13:32:40] <gabewillen> im working on a halgui, but im writing a python version of halcmd
[13:33:06] <gabewillen> i can use every function thus far, and objdump shows rtapi_mutex but i can't access it from that library
[13:33:10] <cradek> hm, are you sure that wasn't already done?
[13:33:44] <gabewillen> well there is _hal.so, but its not wrapping every part of hal
[13:34:02] <cradek> ah, maybe that's what I was thinking of
[13:34:18] <gabewillen> its works great for what gvcp requires
[13:34:32] <gabewillen> but using ctypes is a better approach as far as keeping up with changes
[13:34:51] <gabewillen> much easier than rewriting c code if hal_lib where to change
[13:36:28] <gabewillen> i have almost all the functions working, but, i can load modules, it checks if your using a pre-compiled version of linuxcnc or a devel version. rips the environment for you if your using a dev version
[13:37:44] <gabewillen> i can get the base hal_data struct. But im basing this mostly off of halcmd, and i can't seem to access the rtapi_mutex calls

[14:37:39] <skunkworks> heh
[14:37:48] <skunkworks> I am near LaCrosse

[14:40:02] <ssi> heh nice
[14:40:11] <ssi> tbh the last thing I need is another lathe
[14:40:21] <ssi> I have three lathes, two of them are cnc and only 1 manual mill :(
[14:40:23] <archivist> very badly place levers on that beast
[14:41:06] <L84Supper> Warner & Swasey Company was in Cleveland, probably explains why there are so many of them still around here
[14:43:29] <jdh> http://www.bidspotter.com/forms/staticitem.php?photo=16194087&gallery=21046
[14:43:36] <jdh> how would one transport that?
[14:43:53] <L84Supper> archivist: did you see they guy reaching between the levers in the video?
[14:44:24] <archivist> L84Supper, yes terrible lever placement
[14:44:43] <archivist> about the worst I have seen on any machine
[14:45:23] <L84Supper> jdh: take the cabinets off and it will fit into a pickup
[14:46:27] <L84Supper> I came across one 2 years ago that still had accessories in the original factory wax paper bags from the 50's
[14:47:19] <ssi> jdh: I moved my clausing 12x36 on a tilt-bed rental trailer
[14:47:33] <jdh> ssi: how did you get it off the trailer?
[14:47:37] <archivist> L84Supper, and did you see where his head was when adjusting the cross travel lever
[14:48:08] <ssi> jdh: it has a pair of wood skids bolted lengthwise to the bottom of the cabinets
[14:48:14] <ssi> and we put it on pipes and rolled it
[14:49:09] <Loetmichel> the good old (ancien) egyptian way?
[14:49:14] <Loetmichel> +t
[14:49:19] <ssi> yep
[14:49:23] <ssi> I've moved a lot of machines like that
[14:49:30] <ssi> it sucks, but it works :)

[15:12:51] <Aero-Tec> I need to change owner of a file
[15:13:00] <Aero-Tec> I tried su user

[15:13:45] <Aero-Tec> the owner is root, my ID is in the root group

[15:15:25] <Aero-Tec> do you have to use sudo with some command?

[15:43:40] <Aero-Tec> wow thanks for the help, that little sudo and change owner sure has help me fix a ton of problems
[15:44:54] <Aero-Tec> when I make a file using my windows box the owner is nobody, funny thing is owner nobody trumps the admin and root group user
[15:45:44] <Aero-Tec> any way to set owner nobody so admin user can edit the file?
[15:46:47] <Aero-Tec> also I see there are at least 2 way to name a variable, not sure what will work with the latest version
[15:47:20] <Aero-Tec> what is the simplest and quick way to declare a variable and name it
[15:48:23] <Aero-Tec> like dia for setting the stock size on a lathe
[15:49:47] s1dev|away is now known as s1dev
[15:53:58] <r00t4rd3d> lets say i order 2 separate orders from the same company, i get charged shipping for both orders but they ship them in the same box. Should I get my shipping cost back for 1 order?
[15:55:33] <Aero-Tec> possibly part of it, would depend on size of box and weight
[15:55:58] <r00t4rd3d> flat rate box so size or weight made no difference
[15:57:24] <Aero-Tec> if the 2 small shipping orders size and weight when added together equal what the shipping would be on a larger and heavier box then probably not
[15:57:36] <Aero-Tec> ok then for sure yae
[15:57:44] <Aero-Tec> ask for a refund

[18:54:35] <Loetmichel> oder auf deutsch: raus damit ;-)
[18:54:45] <Daywalker198454> puh doch deutsch ... ;)
[18:54:47] <cradek> Daywalker198454: can you use English?
[18:54:57] <Loetmichel> oh
[18:55:03] <Loetmichel> sorry, here is english ;-)
[18:55:06] <Daywalker198454> not perfect
[18:55:07] <Loetmichel> right
[18:55:25] <ssi> any idea how I can tell the pressure angle of a rack/pinion set?
[18:55:25] <cradek> fortunately none of us is perfect either
[18:55:32] <ssi> they've fallen out of my mcmaster history :/
[18:55:35] <Daywalker198454> ok ill try
[18:55:48] <andypugh> SSI With a protractor.
[18:56:00] <Daywalker198454> i am new on linux cnc
[18:56:23] <andypugh> ssi: In the case of a rack the pressure angle is the tooth angle. It is that simple.
[18:56:35] <Daywalker198454> i used mach3 before and thge start with linux cnc is hard...
[18:56:42] <ssi> andypugh: hm I may be able to take a picture of the rack and measure it on the computer
[18:57:45] <Daywalker198454> i have problems setting up the ini and hal for the folowing system
[18:58:34] <Daywalker198454> mitsubishi MRj2 S Step / Dir Servo´s in combination with linear scales
[18:59:03] <andypugh> Did that work with Mach?
[18:59:32] <Daywalker198454> everything is was ok...
[19:00:49] <Daywalker198454> but i want to feed the tableposition back to linuxcnc
[19:01:11] <Daywalker198454> and i dont know hoe to do
[19:01:19] <Daywalker198454> sorry how
[19:01:21] <Daywalker198454> :P
[19:02:25] <ssi> how are your scales connected to your computer?
[19:03:59] <Daywalker198454> for testing on the 2nd parport..., if everything is fine ill buy a mesa 5i20
[19:04:27] <Daywalker198454> an connect everything to the mesa
[19:04:53] <ssi> when you run linuxcnc, can you open Hal Configuration window, add the parport pins to the watch list, and see the signals changing when you move the axis?
[19:06:06] <Daywalker198454> yes... the signals come in...
[19:06:35] <ssi> look at the man page for encoder
[19:07:06] <Daywalker198454> ???
[19:07:07] <ssi> create an encoder component, add it to the servo-thread, connect signals to it, and it will output a position
[19:07:23] <ssi> connect that positiot signal to the pos-fb pin on the axis
[19:07:46] <ssi> (and actually I think that needs to be on base-thread, not servo-thread)
[19:07:50] <Daywalker198454> i am a stepconf using noob ... ;) how to connect
[19:07:52] <ssi> http://linuxcnc.org/docs/html/man/man9/encoder.9.html
[19:07:59] <ssi> you're going to have to read a bit about hal
[19:08:43] <Daywalker198454> done so many times but dont understand it right now....
[19:09:03] <Daywalker198454> what to do first.. and so on...
[19:09:20] <ssi> first, open up your hal file
[19:09:43] <Daywalker198454> ok
[19:09:46] <ssi> at the top, you should have components being loaded, like "loadrt parport" and such
[19:09:57] <Daywalker198454> ok
[19:10:16] <ssi> so you're going to load the encoder component
[19:10:22] <ssi> with the number of encoder channels you need
[19:10:28] <ssi> loadrt encoder num_chan=3
[19:10:38] <Daywalker198454> ahhh ok...
[19:10:40] <ssi> refer to the page I linked above or the man page (man encoder)
[19:10:53] <ssi> that'll create you three encoders, encoder.0, encoder.1, encoder.2
[19:11:44] <ssi> then, according to the man page, there's two functions that need to be added to threads
[19:11:57] <ssi> since you're doing software stepping, you should have a base-thread and a servo-thread
[19:12:14] <Daywalker198454> ok..
[19:12:23] <ssi> addf encoder.update-counters base-thread
[19:12:28] <ssi> that one needs to happen frequently
[19:12:38] <ssi> addf encoder.capture-position servo-thread
[19:12:44] <ssi> man page says that needs to happen less frequently
[19:12:49] <ssi> so I'm assuming that means servo thread is fine
[19:13:01] <Daywalker198454> ok
[19:13:02] <ssi> the addfs will attach those functions to the corresponding threads
[19:13:07] -!- GammaX-Shop [GammaX-Shop!~GammaX-Sh@unaffiliated/gammax] has joined #linuxcnc
[19:13:13] <ssi> which means they'll get called when those threads run
[19:13:24] <Daywalker198454> k
[19:13:33] <ssi> then you need to connect your signals
[19:13:38] <ssi> is it an indexed encoder?
[19:13:46] <ssi> A/B/Z? or just A/B?
[19:13:57] <ssi> I'm assuming it's quadrature
[19:14:01] <Daywalker198454> yes it has indexsignal
[19:14:05] <Daywalker198454> yes
[19:14:06] <cradek> what position feedback goes to your step-servo drives?
[19:14:08] <Daywalker198454> ttl
[19:14:33] <Daywalker198454> ecoder on motorshaft
[19:14:43] <Daywalker198454> ac servo´s 750W
[19:14:48] <ssi> so you have rotary encoders on the motors, and linear encoders on the axes
[19:14:49] <ssi> weird
[19:15:04] <cradek> ah ok. very unusual setup.
[19:15:28] <ssi> so now wire the parport pins to the encoder
[19:15:30] <cradek> maybe you will want to run the step-servos stepgens in velocity mode
[19:15:35] <ssi> you know the hal names of the pins?
[19:15:47] <ssi> it'll be something like:
[19:16:24] <ssi> net x-enc-a encoder.0.phase-A <= parport.0.in-01
[19:16:33] <ssi> (x-enc-a is the signal name, and I completely made it up)
[19:16:40] <ssi> you need to attach A, B, and Z for each encoder
[19:17:23] <ssi> and you'll also need to setp encoder.0.position-scale XXX
[19:17:26] <Daywalker198454> ok.. the <= is for input and => for output?
[19:17:28] <ssi> whathever the scale of the encoder is
[19:17:40] -!- tmcw has quit [Remote host closed the connection]
[19:17:41] <ssi> <= and => don't mean anything, hal ignores them
[19:17:50] <ssi> they're there to keep straight what's what, for your own menefit
[19:17:52] <ssi> benefit
[19:18:15] <ssi> but yeah, I used it there to indicate the signal from parport goes into the encoder phaseA pin
[19:18:35] <Daywalker198454> can i write "net x-enc-a encoder.0.phase-A parport.0.in-01" too??
[19:18:48] <ssi> yep
[19:19:01] <ssi> whatever makes it clear in your mind :)
[19:19:08] <Daywalker198454> ok.. i´ll try
[19:19:34] <ssi> the position-scale needs to be set to the counts per unit
[19:19:34] <Daywalker198454> it is hard to understand when nobody helps you understand it-... :P
[19:19:42] <ssi> it's a tall mountain to climb
[19:19:45] <ssi> but we all had to do it :)
[19:20:11] <Daywalker198454> mach3 was really simple
[19:20:19] <ssi> it's TOO simple
[19:20:41] <Daywalker198454> but you can´t close the loop in realtime
[19:20:52] <Daywalker198454> but u have to understand.. :P
[19:21:05] <cradek> you can get a very easy and simple setup like mach3 using stepconf. just ignore your scales.
[19:21:48] <Daywalker198454> did it, but linux should know the position of the table
[19:21:58] <Daywalker198454> not to comp. backlash or something
[19:23:32] <cradek> so like mach3, it is simple to do something simpler than you want
[19:23:37] <ReadError> servos sound like a PITA ;/
[19:23:47] <Daywalker198454> @ ssi and cradek are u often here

[19:34:00] <FinboySlick> When picking a hobby mill, I greatly underestimated the awesomeness that is a tool changer too.
[19:34:16] <FinboySlick> I definitely would have given the tormach more consideration.
[19:34:35] <ssi> yeah the tormach is a nice machine, but it's spendy for what it is
[19:34:39] <ssi> what machine did you end up with?
[19:35:05] <FinboySlick> "
http://www.syilamerica.com/machine_x5speed.php
[19:35:25] <syyl_> a toolchanger is incredible usefull
[19:35:26] <syyl_> :D
[19:35:27] <FinboySlick> Considering the price of a Tormach, I'd have had a much nice marchine.
[19:35:31] <ssi> hm
[19:35:32] <ssi> yes
[19:35:44] <ssi> I'm having a hard time getting a sense of scale on that machine
[19:35:48] <ssi> looks small
[19:35:54] <ssi> BF20 sized maybe
[19:35:56] <FinboySlick> It is pretty small.
[19:35:57] <ssi> or smaller?
[19:36:14] <FinboySlick> It's bigger tan an X3
[19:36:14] <syyl_> bigger than a bf20
[19:36:28] <FinboySlick> About 800 pounds with stand.
[19:36:30] <syyl_> what kind of spindle nose does the x5 have?
[19:36:32] <syyl_> collets?
[19:36:33] <ssi> 24k spindle?
[19:36:52] <FinboySlick> 24k spindle, R16 if I'm not mistaken.
[19:37:05] <ssi> R16?
[19:37:07] <ssi> not ER16?
[19:37:21] <FinboySlick> ER, yes.
[19:37:24] <FinboySlick> Not sure on the 16.
[19:37:29] <FinboySlick> 7mm max.
[19:37:33] <syyl_> thats er11
[19:37:36] <ssi> yea
[19:37:37] <FinboySlick> Ah, yes.
[19:37:41] <ssi> tiny
[19:37:43] <syyl_> and pretty small ;)
[19:37:45] <ssi> I have ER16 on my little engraver :P
[19:38:16] <FinboySlick> Given the rigidity, and spindle, I don't think it'd do very well with bigger tools anyway.
[19:38:17] <ReadError> it has a tool changer ?
[19:38:25] <FinboySlick> No.
[19:39:19] <FinboySlick> It's an option on a similarly priced standard X5 though.

[19:40:00] <FinboySlick> I could relatively easily convert the head of the machine to a standard spindle (instead of high speed)
[19:40:16] <FinboySlick> There's a lot of room in that casting.

[19:41:53] <syyl_> at least they dont wear that fast as the soft chinese castiron of normal guideways
[19:41:56] <FinboySlick> It's got no backlash and is silky smooth.
[19:42:23] <FinboySlick> I'll probably take it all appart, lap things nice, adjust and tweak everything that can be and cut my losses ;)
[19:42:49] <FinboySlick> It's just a heck of a lot of work getting there.
[19:42:54] <syyl_> :D
[19:43:09] <syyl_> but at least it looks a bit like a mini-vmc
[19:43:10] <syyl_> :D
[19:43:14] <FinboySlick> Castings are nice and heavy, it *could* be a nice machine.
[19:43:52] <syyl_> the x7 looks cool

[19:52:45] <ssi> syyl_: that's awesome
[19:53:10] <ssi> I bought these encoders a long time ago, thinking the bases would mount on the back of a stepper easily
[19:53:12] <Gammax-Shop> I WOuld do that only if it gave an extra step or sumtin if it missed it.
[19:53:13] <ssi> but it wasn't the case
[19:53:23] <ssi> ended up 3d printing mount adapters for them
[19:53:25] <Gammax-Shop> Or configure it so the steppers were like dc motors ie servos

[20:06:50] <andypugh> Daywalker198454: For your step-servos what you need is a standard servo setup, but instead of the PID component driving a PWM generator (pwmgen) it needs to drive a step-generator (stepgen) in velocity mode.
[20:07:22] <andypugh> I can't decide whether it is easier to start with a stepper config, or a servo config, to set that up.
[20:08:15] <andypugh> I _think_ what you should do is get it all set up and working as a pure step-system, with no linear slides being used then consider modifying the config to use slides.
[20:08:49] <andypugh> However, if the motors have encoders, I am not really sure what the linear scales add.

[21:50:52] <r00t4rd3d> :)
[21:51:08] <r00t4rd3d> you can run a coolant pump and a spindle

[22:07:11] <andypugh> But, if all you want to do is send "things" to "places" then the HAL "limit3" component is a complete motion controller. And you can drive it with the G-code analog-out pins.
[22:07:41] <andypugh> They all mean something.

[22:12:57] <ds3> trying to say that IJK have other uses beyond arcs
[22:15:05] <andypugh> They can be seen as generic XYZ modifiers, I think?

[23:31:26] <JT-Shop> I do have some strange music though
[23:31:52] <L84Supper> Madness was a Ska band, then went pop

[23:41:11] <JT-Shop> fun to shoot a dozen or so from a skeet launcher and try to blast them in flight
[23:41:33] <L84Supper> all good uses
[23:42:01] <ssi> well I'll have plenty for doing all these fun things and more

[23:43:15] <PetefromTn> anyone here good with braking resistors?
[23:43:20] <L84Supper> do they still music on those disc things?
[23:43:25] <ssi> jdh: it's still higher bandwidth than the internets
[23:43:25] <jdh> I'm good with breaking resistors
[23:43:29] <ssi> L84Supper: yeah believe it or not
[23:43:35] <ssi> although the CD was an afterthought... the vinyl was the real project
[23:43:46] <jdh> ssi: depends on who's driving.
[23:44:27] <ssi> true
[23:44:45] <PetefromTn> I am TRYING to use a water heater element with the Z axis drive on my Cincinatti Arrow 500 VMC...
[23:45:06] -!- gabewillen [[email protected]] has joined #linuxcnc
[23:45:13] <ssi> but?
[23:45:14] <L84Supper> PetefromTn: sounds good, any problems so far?
[23:45:18] <PetefromTn> I read the manual on the TSTA-30 teco drive and it indicates a minimum of a 23 ohm resistance
[23:45:41] <Tom_itx> what's the element resistance?
[23:45:44] <L84Supper> at what voltage?
[23:45:52] <PetefromTn> I bought a water heater element that is exactly 24 ohms and is 2500 watt 240v unit
[23:46:06] <L84Supper> sounds good so far
[23:46:32] <Tom_itx> you mounting it under your coffee pot so you can make use of the extra heat?
[23:46:39] <JT-Shop> LOL
[23:46:51] <PetefromTn> I fabricated a small bracket from a piece of square tool steel and tig welded the threaded portion of the element to it and hooked it up from the P to the PC inputs on the TSTA-30
[23:47:03] <JT-Shop> 23, 24 whatever it takes
[23:47:06] <L84Supper> auxiliary water heater
[23:47:47] <PetefromTn> When we powered it up there is ONE setting that I can find that determines the resistor power.
[23:48:22] <PetefromTn> It is CN012 and it WAS set to 60 but we upped it to 300ohms...
[23:49:22] <PetefromTn> When we turned it on there was a strange clicking noise that sounded like a relay was msifiring or something. I quickly powered it down and checked everything
[23:49:32] <PetefromTn> Found nothing in particular.
[23:50:34] <PetefromTn> When I removed the leads to the resistor and reinstalled the little shunt that was there I also changed that parameter back to 60. powered it back up and it STILL made the noise. I shut it off again.
[23:51:03] <PetefromTn> Then I let it sit for awhile and now it seems to work in Z axis drive as I had control with no noise and head goes up and down smoothly and quietly...
[23:51:24] <PetefromTn> I am stumped at what the hell that clicking noise was and why... Afraid to try it again.
[23:51:31] <PetefromTn> any ideas?
[23:51:41] <L84Supper> are there any relays?
[23:51:56] <L84Supper> all semiconductors?
[23:52:01] <JT-Shop> gentlemen I'll leave you with this inspirational song
http://www.youtube.com/watch?v=m_WRFJwGsbY
[23:52:01] <PetefromTn> sure three of them but they have nothing to do with this Z drive?

[23:52:31] <PetefromTn> no mechanical relays...
[23:52:40] <Tom_itx> it wasn't causing an under power condition to trip the relays was it?
[23:53:37] <PetefromTn> how? The relays are used for witching the main contactor, a seal in circuit relay, and the last one is for the spindle motor fan...
[23:53:47] <L84Supper> maybe stuff on the z-axis screws?
[23:54:14] <L84Supper> or was the sound from the control panel?
[23:54:14] <PetefromTn> I never actually moved the axis.... I only energized the servos and heard the noise and quickly hit the E-stop
[23:55:30] <PetefromTn> No it was from the electronics cabinet as far as I could tell. The second time I tried it before reverting to the previous setup I walked back there quickly to see if I could find the source of the clicking but could not tell quick enough and felt scared of the possible problem so I killed the main switch.
[23:56:04] <L84Supper> but it runs fine now?
[23:56:48] -!- Valen [[email protected]] has joined #linuxcnc
[23:57:01] <PetefromTn> yeah I actually just lost power from a bad thunderstorm a bit ago so have not been able to check it but once I reverted to the original setup I was able to move everything and checked the coolant pump etc... no issues that I could find... crazy.
[23:57:51] <PetefromTn> Now that the storm has passed I am gonna try to power it up and home everything again. Did not check the spindle motor as I had not messed with it yet.
[23:58:40] <Tom_itx> get a 2nd pair of hands on the control while you stick your head inside the cabinet

[23:59:50] <PetefromTn> Really glad I went with the estop circuit that kills power completely.
