[01:10:07] <ReadError> yea, i dont want wood on it :)
[01:10:09] <jdh> even though I think cnc lathes are probably the least useful thing for me.
[01:10:16] <ReadError> maybe just the spoil board
[01:10:44] <r00t4rd3d> a good part of my machine is aluminum

[01:20:13] <alex4nder> ReadError: yes, the taig lathes
[01:21:38] <ReadError> i got one for xmas
[01:23:43] <r00t4rd3d> the first thing he made was a rather large black dildo

[03:22:33] <ReadError> got my vac setup ;)
[03:23:13] <ReadError> aww man its sideways for me
[03:23:36] <Tom_itx> no kidding
[03:24:01] <ReadError> yea i been in work mode not cleaning mode
[03:24:20] <Tom_itx> no mist lube?
[03:24:29] <ReadError> nah i would make even more mess with that
[03:24:37] <Tom_itx> hard on bits
[03:24:59] <ReadError> these are only 3$ each
[03:25:07] <ReadError> if i had nicer stuff i would probably
[03:25:25] <Tom_itx> learn good habits no matter what
[03:25:50] <ReadError> does a mist lube require a spraying setup?
[03:25:56] <ReadError> or just a spray bottle
[03:27:22] <Tom_itx> you can do it either way
[03:27:38] <Tom_itx> the good ones use an air compressor and a reservoir
[03:27:40] <ReadError> well, i noticed when i put a lube on it, the chips want to gunk up and stick around
[03:27:55] <r00t4rd3d> mill me a qc

[03:28:43] <ReadError> you seen that one?
[03:28:57] <r00t4rd3d> ya that one
[03:29:06] <ReadError> i got full blown gcode if you want that
[03:29:13] <ReadError> its for 1/8" endmill tho
[03:29:40] <r00t4rd3d> i have those but i would probably do it wood
[03:29:53] <jdh> how would spruce or something work for that?
[03:30:03] <ReadError> i seen plenty of folks use aluminum on routers r00t4rd3d
[03:30:13] <ReadError> jdh, not sure, i dont know much about woods/strengths
[03:30:23] <ReadError> but wood would work i think
[03:30:34] <r00t4rd3d> lots of people use wood
[03:30:58] <ReadError> you making jabs at my mom again?
[03:31:49] <Tom_itx> what did you use to generate the gcode?
[03:31:51] <r00t4rd3d> most kits are laser but plywood
[03:31:58] <r00t4rd3d> cut*
[03:32:08] <ReadError> Tom_itx, HSMXpress
[03:32:09] <ReadError> its free
[03:32:12] <ReadError> pretty decent too
[03:32:23] <Tom_itx> do you start with a solid model or what?
[03:32:49] <ReadError> yup
[03:32:58] <jdh> free + solidworks?
[03:32:59] <ReadError> its built in so if i change the model, the code adapts
[03:33:00] <Tom_itx> solidworks add on?
[03:33:02] <ReadError> yea
[03:33:07] <ReadError> its completely free though
[03:33:10] <Tom_itx> what ver will it work with?
[03:33:18] <ReadError> 2009-2012 i think
[03:33:22] <Tom_itx> crap
[03:33:30] <jdh> except SW is far from free!
[03:33:51] <r00t4rd3d> borrow a boat
[03:34:29] <Tom_itx> ahh.. limited to 2.5d
[03:34:37] <Tom_itx> no 3d surfaces
[03:34:56] <ReadError> yea ;/
[03:34:57] <Tom_itx> mine'll do surfaces
[03:35:00] <ReadError> thats how they get you
[03:35:04] <ReadError> what do you use Tom_itx ?
[03:35:12] <Tom_itx> an old ver of smartcam
[03:35:15] <r00t4rd3d> if i had the dimensions I could make that in Aspire in minutes
[03:35:23] <ReadError> oh i use visual mill also
[03:35:27] <jdh> export it as a dxf
[03:35:28] <ReadError> its pretty decent as well
[03:35:44] <ReadError> i can when i get back upstairs
[03:35:48] <ReadError> babysitting the mill
[03:36:03] <ReadError> i suspect all this airflow will keep things cool as well
[03:36:10] <ReadError> theres tons of air going around the endmill
[03:36:15] <Tom_itx> how does it handle pockets etc?
[03:36:29] <jdh> does air really cool well?
[03:37:02] <ReadError> Tom_itx, worked good on the last one
[03:37:16] <ReadError> i should get my IR gun and see what the temp difference is
[03:37:53] <Tom_itx> how much is solidworks now?
[03:38:35] <ReadError> no idea tbh
[03:38:42] <ReadError> i hate the scam they have going
[03:44:31] <ReadError> i figure after a few more mcmaster orders i will never need to buy ziplock bags again
[03:48:41] <jdh> they don't last
[03:50:20] <Tom_itx> for what?

[04:20:38] <thrile> I have a problem. I have a machine with a maximum A and V. I need it to reach a specific point X at a specific time (t). It can do so only by applying a fixed acceleration (a) for tb seconds, and then applying -a for tb seconds before stopping. Thus, I can control its position only by messing with the acceleration. Here's a reverse run, I can't figure out the formulas.
https://docs.google.com/file/d/0B9B78Ofn6Af3c0dkU3VKUW11Vmc/edi
[04:21:04] <thrile> (I'm interested in the math behind figuring out discrete X points, and the blending time start position, in theory)
[04:36:58] <pcw_home> stopped at beginning and end?
[04:37:33] <jdh> hsmworks/hsmexpress are owned by Autodesk... but it's for solidworks only.
[04:38:21] <thrile> yeah, no blending between motions, I'll do that later.
[04:38:30] <thrile> for now I just want to understand the math behind a simple trapezoidal motion.
[04:39:37] <pcw_home> P = 1/2at^2 so A= 2P/T^2 (for first 1/2 of trip)
[04:45:22] <thrile> hmm
[04:45:28] <thrile> that seems about right
[04:45:44] <thrile> it graphs ok in mathematica, so, yeah...
[04:46:13] <thrile> but how do I know where's my transition point? (the ones between 0 and constant acceleration)
[04:57:55] <pcw_home> for trapezoidal you need to have the maxvel specified (and then break the trajectory into 3 pieces: ramp-up (to maxvel), slew(at maxvel) , ramp-down)
[05:00:32] <tjb1> ReadError: r00t4rd3d is scared to cut aluminum
[05:00:40] <tjb1> all he cuts are paradise boxes :P
[05:01:27] <ReadError> lol
[05:02:55] <toastyde1th> aluminum cuts pretty easily
[05:03:15] <toastyde1th> HUNDRED AND TWENTY INCHES A MINUTE
[05:03:20] <toastyde1th> baller statusssss
[05:05:35] <thrile> yeah, knowing maxvel of course.
[05:06:39] <thrile> also, what makes the X snap exactly to t (at least mathematically)? is a different value of a used sometimes? or is the maxvel altered in some way?
[05:06:49] <toastyde1th> at my old college i used to cut aluminum with a 4" facemill at 80-100 ipm because it was so loud
[05:07:05] <toastyde1th> people would come out of classes to watch
[05:07:45] <toastyde1th> 6000 rpm, 100 ipm, and .150 deep
[05:07:47] <ReadError> cut super clean ?
[05:08:07] <toastyde1th> the facemill was fucked up so it never cut clean
[05:08:28] <toastyde1th> the teeth pockets were all banged up and filed back down so the teeth were all at different heights

[09:37:51] <mrsun> what is normal winter temperatures there ?
[09:39:10] <IchGuckLive> -7°C
[09:39:38] <IchGuckLive> it is cold enoph if you got a open shop doar and parts with length > 4m

[16:34:30] <thrile> I'm trying to understand the math behind the trapezoidal profile.
[16:34:51] <IchGuckLive> in lath or the tread it self
[16:35:03] <IchGuckLive> or speed profiling Ramps
[16:35:17] <thrile> the speed profiling ramp
[16:35:28] <thrile> not acme machining :)
[16:35:53] <thrile> what I don't understand is how to express this mathematically.
[16:36:11] <thrile> i've come up with a "reverse" example, starting from what I want to obtain, to figure out my formulas, with no success.
[16:37:10] <thrile> for example, I graphed that if I apply 4mm/s^2 of acceleration for 25 seconds, 50 of the "speed" of 100mm/s and -4mm/s^2 for 25 seconds, I'll reach exactly 7500mm in 100 seconds.
[16:37:42] <Jymmm> LOL you HAVE to watch "Iron Sky" (on netflix)
[16:38:11] <thrile> Esentially, I'm trying to come up with a set of equations where I put 7500 mm in and 100s (XY and F) and a range (or just the correct) values should come out - 4mm/s^2 for 25 s
[16:39:01] <thrile> Jymmm: you should watch primer

[16:41:09] <Jymmm> thrile: added to queue =)
[16:41:12] <thrile> anyway, what I don't understand is what are my limits/boundry conditions? for example, I need to get to 7500 in 100s, that would imply a linear speed of 75mm/s. But how would I know to pick 100mm/s, given the fact the critical distance has lower displacement then the maximum velocity one (obviously)
[16:42:05] <thrile> and of course, how would I know to accelerate by 4mm/s^2? Would there be any cases where I'd use less? Or what about overriding the maximum velocity by 0.9-1.1 to keep up?

[18:01:27] <Connor> Hey Guys, what's a good PPR for encoder on spindle? (Using Par-port, no mesa)
[18:02:04] <pcw_home> depends on your base thread period
[18:02:22] TekniQue_ is now known as TekniQue
[18:02:23] <Connor> 25 or 30k I think..
[18:02:26] <Connor> Atom based PC
[18:03:27] <Connor> 48,96,100,125,192,200,250,256,384,400,500,512,800,1000,1024,2048 are my options
[18:03:38] <pcw_home> so max 33KHz edge rate but you probably want about 2x safety margin
[18:03:54] <pcw_home> what is the maximum spindle speed?
[18:09:02] <archivist> I have 48 on my lathe
[18:10:34] <Connor> 7000RPM.
[18:10:40] <Connor> oh. and don't forget index.
[18:10:57] <archivist> not many rpm on spindle I start to lose counts and get a bad thread
[18:11:34] <pcw_home> 48 would be 192 counts/rev or 22400 Hz count rate at 7000 RPM so probably just OK at 30 usec
[18:11:59] <pcw_home> but not much margin
[18:12:02] <ReadError> http://i.ebayimg.com/t/New-CNC-Mill-Milling-Machine-Complete-with-Cooling-System-Grizzly-G0704-/00/s/MTIwMFgxNjAw/$T2eC16VHJHEE9ny2rTo9BQtORuvri!~~60_57.JPG
[18:12:12] <ReadError> seems like the x axis would run in to that metal tray
[18:12:24] <Connor> That was my thought..
[18:12:31] <Connor> Not to mention.. it's priced WAY to high.
[18:12:37] <ReadError> yea
[18:12:38] <ReadError> 5.1k
[18:12:51] <Connor> My X stepper is on the other side.
[18:13:13] <ReadError> did you buy the conversion kit?
[18:13:18] <Connor> No.
[18:13:23] <ReadError> seems pretty expensive
[18:13:51] <Connor> Made all mine on the mill manually.. First time I ever worked with a mill.. had some lathe experience as a Kid.. but, that was YEARS ago.
[18:17:15] <archivist> pcw_home, does your math include the dead time when the part port is not being looked at (software polling), I dont seem to be able to go anywhere near that speed
[18:18:58] <pcw_home> No I am assuming perfect sampling (but would allow about 2x margin for quadrature error and sampling uncertainty
[18:20:17] -!- sumpfralle [[email protected]] has joined #linuxcnc
[18:20:55] <pcw_home> so for safety i would not want to try and track more that 1/2 the edge rate (so 22400 is probably too high for reliable operation at 48 PPR/7000 RPM/33KHz sample rate)
[18:21:27] <Connor> okay, base thread is 35000, servo is 1000000
[18:22:10] <pcw_home> yeah so even 48 PPR is iffy (unless you dont really need to use the encoder at high speeds)
[18:22:16] <Connor> how do you get 192 out of 48 PPR ?
[18:22:20] <archivist> I must measure my max rpm where I lose it
[18:22:56] <pcw_home> a 48 ppr encoder has 4 edges per cycle 48x4 =192
[18:23:26] <archivist> only if it has A and B in quadrature
[18:23:32] <pcw_home> Yes
[18:23:51] <archivist> I only have A and index
[18:25:14] <pcw_home> so you should be able to do twice as well speed wise
[18:25:57] -!- Sendoushi has quit [Remote host closed the connection]
[18:25:59] <pcw_home> if its a home built encoder the sensors may be too slow (photo darlintons are)
[18:26:28] <Connor> Probably will be limiting it to around 6500.. any faster and the motor is out of range on continuous duty on voltage.
[18:27:29] <pcw_home> So marginal for quadrature probably OK for A only (unidirectional)
[18:27:38] <pcw_home> (at 48 PPR)

[18:29:36] <ve7it> I found high spindle rpms were not very useful when cutting threads.... the Z axis had problems keeping up.... but I was trying to cut 0.5" pitch thread!
[18:30:11] <pcw_home> Yeah so you may not need the encoder above a few K RPM anyway
[18:30:59] <pcw_home> wow .5" pitch would tax the Z axis
[18:39:16] <Connor> Going to use is for Tapping and RPM..
[18:39:56] <Connor> What's a good RPM for tapping? This is a 1 to 1 setup.. so, Not sure how torque will be a lower RPM..
[18:40:09] <mrsun> hmm is mild steel good enough for gibs ?
[18:40:20] <mrsun> or what material are they usaly made out of ?
[18:41:27] <pcw_home> I suspect the RPM limitation for tapping is chiefly how fast the spindle can reverse
[18:43:37] <Connor> Why would that mater? Does the Z not follow the speed of the spindle.. as it slows down, does the Z not slow too?
[18:44:47] <pcw_home> the plunge depth may exceed the tap length if the starting RPM is to high
[18:45:20] <pcw_home> which will cause emission of bad words
[18:45:51] <Connor> Probably would only do through hole tapping.. and might get one of the compression tap heads for Tormach.
[18:48:25] <pcw_home> you would probably want to air tap at various starting RPMs to
[18:48:27] <pcw_home> see what distance is needed for the spindleto come to a stop
[18:49:08] <Connor> Well that not change when tapping? More friction? Also, Have Dynamic resistor on my SCR controller..
[18:49:11] -!- ktchk has quit [Read error: Connection reset by peer]
[18:49:29] <Connor> but, Not sure it'll come into play... seeing as it go straight to reverse.

[18:52:22] <pcw_home> I guess the question is how many turns it takes to stop the
[18:52:23] <pcw_home> spindle via a reverse at various RPMs
[19:13:59] <archivist> its about 160 rpm where I lose it, the opto is good to max speed , the period is not 50:50 though like the ideal

http://huntingtonscrew.com/cnc.mp4 (volume sry)
[19:37:45] <Index-Werke> VERY pleased with it.
[19:43:09] <pcw_home> but 2 ms should be sampled 50 times at 25 KHz so I still dont understand
[19:47:29] <pcw_home> Sure its not a photo Darlington OPTO? those are often dreadfully slow
[19:49:21] <archivist> no I go direct from the encoder optos to the pc, base period is 40000 , so Im running slower
[19:49:43] -!- vladimirek [[email protected]] has joined #linuxcnc
[19:50:44] <pcw_home> 40 usec base thread is 25 KHz so should be fine for 3000 RPM or more

[22:11:48] <lwizardl> hello
[22:13:21] <lwizardl> I'm looking for a good application on linux that can be used to create the patterns to be later cut out on a cnc machine. I watched a video from someone using windows based application and seems he was using adobe illistrator for his.

[22:23:47] <lwizardl> I am trying to keep windows out of my life for good
[22:23:56] <JT-Shop> good plan
[22:24:10] <tjb1> Its very dark without windows in your life

[22:25:03] <lwizardl> tjb1, lol funny
[22:25:45] <tjb1> Are you looking for software to do this on linux?
[22:25:51] plushy1 is now known as plushy
[22:25:52] <lwizardl> yes
[22:26:35] <lwizardl> I have downloaded just about everything that comes up in the ubuntu software list and nothing seems to be as I wanted. most seems to be more like scripting then render in 3d
[22:26:37] <Vq> tjb1: They invented the oil lamp around 9000BC, works great.
[22:26:51] <tjb1> I'm particular to light bulbs
[22:27:08] <Vq> tjb1: There you go. :)
[22:27:28] -!- tronwizard has quit []
[22:27:34] <tjb1> Not sure lwizardl, the school just got a laser cutter today and I know he said something about photoshop can only rasterize and you have to use illustrator for vectors
[22:27:52] <tjb1> And then something about the color determines laser power
[22:27:58] <lwizardl> tjb1, inkscape also does vectors
[22:28:21] <tjb1> I think he was just talking about CS at the time
[22:28:47] <lwizardl> which is what I have been using so far for all my art needs (which are very basic stuff)
[22:29:05] <lwizardl> k
[22:29:54] <lwizardl> I plan to build my cnc machine when taxes come in. so I have time still but trying to get used to the program i will be using so I can have some stuff ready to use for testing the build

[22:35:57] <JT-Shop> you paid way too much in taxes if you can build a cnc machine with your refund

[22:39:06] <abetusk_w> could someone (or more than one) give a brief description of their toolchain? What do you use to create models and what do you use to export to gcode? Are you using BRL-CAD, Blender, OpenSCAD, something else? How do you export to gcode? Do you export to STL or DXF and then use another tool to convert to gcode? If so, which tool (MeshLab, something else)?
[22:39:21] <lwizardl> I don't plan to build a huge machine.
[22:40:09] -!- pjm [[email protected]] has joined #linuxcnc
[22:40:12] <lwizardl> and yes I do think taxes are too high
[22:43:47] <JT-Shop> abetusk_w: I use gedit to generate my G code when I'm not using ngcgui
[22:45:51] <abetusk_w> meaning you don't bother with higher level 3d modelling at all and just write straight g-code?

[23:15:00] <Tom_itx> JT-Shop did you get my reply to the logsplitter?
[23:15:24] <JT-Shop> yes
[23:15:34] <JT-Shop> do you still have it?
[23:15:43] <Tom_itx> wasn't sure if gracie called you or not by then :D
[23:15:46] <Tom_itx> no
[23:16:02] <Tom_itx> funny, i've got that last word indicator also
[23:16:14] <JT-Shop> gracie called me and I read it this morning
[23:16:32] <Tom_itx> i'm pretty sure it was 3"
[23:16:38] <Tom_itx> you'll get more power from 4
[23:16:53] <Tom_itx> and i used the smaller of those 2 pumps
[23:16:57] <Tom_itx> 11gpm iirc
[23:17:53] <Tom_itx> that was probably 20+ yrs back
[23:18:49] <AR_> i'm having post partem depression as i am building my machine

[23:23:05] <Tom_itx> the lift should be on a lever though instead of pumping it
[23:25:23] <JT-Shop> he has a winch, the pump is just to position the boom up or down
[23:26:29] <Tom_itx> i doubt you need the legs either
[23:28:21] <JT-Shop> some of the other photos show it lifting some huge chunks of wood
[23:29:23] <Tom_itx> i had a trunk about that size i ended up halving with the saw first

[23:35:15] <Tom_itx> i thought that was a term for bare hand fishing
[23:37:01] <Tom_itx> i had one once i cut all the way around and still had about a foot in the middle hanging on

[23:41:10] <Tom_itx> you gotta ask to get an answer
[23:41:36] <JunkieHobbo> I have a PueLogic PLC4c-G2 BoB I am testing out, The trouble is with the Parallel Port Pin Setup...I cannot get the Steppers to move!

[23:45:29] <AR_> how does one match VFDs to motors?
[23:45:49] <JT-Shop> hp
[23:45:50] <JunkieHobbo> Manual show for Pin 2-5 as STEP1,STEP2,STEP3,STEP4 Pin 6-9 DIR1,DIR2,DIR3,DIR4 Pins 10-13 IN1,IN2,IN3,IN4 , With that I am wondering how the Parallel Port mapping should look in the Setup on LinuxCNC???
[23:46:25] <JT-Shop> the pins should be the same
[23:46:53] <JT-Shop> you might need to invert the pins to get them to work
[23:48:56] <JunkieHobbo> So for PIN 2-4 I have them Set as X Step,Y Step, Z Step, A Step, PIN 6-9 I Have them set as X Dir, Y Dir, Z Dir, A Dir what should PIN 10-13 be set as?
[23:49:39] <JunkieHobbo> I am guessing they will be the Limit Switches...
[23:50:54] <tjb1> 10-13 are inputs
[23:51:09] <tjb1> 1 and 17 are outputs
[23:51:43] <JT-Shop> if you have limit switches
[23:51:57] <JT-Shop> does your bob need an enable pin
[23:52:25] <ReadError> is it possible to fireoff an air compressor at preset intervals?
[23:52:31] <ReadError> if i hooked it to a solenoid
[23:52:43] <ReadError> and had some lockline going out of it
[23:52:47] <ReadError> locline*
[23:52:50] <JunkieHobbo> I have the Enable set to Pin 1
[23:55:23] <Tom_itx> tjb1, something about hyperthread
[23:55:44] <Tom_itx> what's that option in the bios you're supposed to disable for dual core and linuxcnc?
[23:55:56] <Tom_itx> anybody?
[23:56:45] <JT-Shop> dual core is isolcpus
[23:57:21] <JunkieHobbo> I ran the config with invert option on pins and still the same result...
[23:57:37] <Tom_itx> EPP set in the bios?

[23:58:15] <Tom_itx> tjb1, mine seemed to run fine either way
[23:59:32] <Valen> Tom_itx: you should disable hyperthreading
[23:59:44] <Valen> isocpus is kernel stuff
[23:59:51] <Valen> HT screws latency hard
