[04:30:51] <Maluseth> hi, does anyone know where i can purchase micro-cnc machines for micromanufacturing?
[04:31:18] <Maluseth> not manual but computer operated, so to work with a CAD
[04:37:44] <r00t4rd3d> http://www.microcarve.com/mcMV1.html
[04:38:24] <r00t4rd3d> those need the electronics and steppers still
[04:44:01] <fenn> oilite bearings is not exactly suitable for high precision machining
[04:45:14] <fenn> it's possible that what he's looking for doesn't exist as a purchaseable commodity
[04:47:56] <fenn> i thought this was pretty cool
http://unit.aist.go.jp/amri/group/imms/en/HP/research/portable-e.htm
[04:51:37] <fenn> that uses "laminated piezoactuators"
[04:53:34] <KimK_laptop> Maluseth: What size blank are you looking for? And finished to what tolerance?

[04:56:21] <kwallace1> Howsabout:
http://www.cameronmicrodrillpress.com/cnc.html
[04:58:56] <kwallace1> It looks like it uses Flashcut, but could be converted I supose.
[04:59:40] <Maluseth> i dont really know the terms you are mentioning kwallace, i am just getting this funding and building a micromanufacturing fabrication lab
[05:00:21] <fenn> flashcut is a "competitor" control software (this channel is about an open source machine control software package)
[05:00:28] <Maluseth> and i am hoping, without any previous expertise, i could land in on fundamental tools i need in order to design and fabricate machinary in micro scale
[05:01:19] <Maluseth> kwallace, i saw that ad earlier today
[05:01:28] <Maluseth> how much do you think it'll cost?
[05:01:57] <Maluseth> and would i need a laser cutter go along with it... any additional equipments to cover all angles?
[05:02:23] <kwallace1> Cameron's drill presses seem to be well established in a particular niche, but I'm not sure what niche it is.
[05:02:36] <Maluseth> micromanufacturing?
[05:02:39] <Maluseth> IDK
[05:03:49] <kwallace1> Some lathe functions can be done with a mill. Just place the tool on the table, and the work in the spindle.
[05:04:30] <fenn> aerospace & avionics, medical R&D and electronics" - i bet they sell to prototyping labs mostly
[05:06:25] <kwallace1> They are in the next town from me. I visited the shop a couple years ago. They seemed to do most or all their business at trade shows.
[05:08:03] <kwallace1> They had spindle motor housings in the shop that day, that they cast on site.
[05:09:34] -!- postaL has quit [Ping timeout: 240 seconds]
[05:11:32] <fenn> neat. i want to do that
[05:12:03] <kwallace1> I know nothing about CNC laser machines, so it should be easy to make one :)
[05:12:55] <fenn> well, all the hard stuff's done by the time you buy all the optics
[05:14:07] -!- FinboySlick has quit [Quit: Leaving.]
[05:17:06] <kwallace1> Speaking of optics, I've gotta make one of these:
http://starryridge.com/mediawiki-1.9.1/index.php?title=Photo_Gallery
[05:18:02] <kwallace1> or :
http://www.artinso.com/astronomy/archive_astrosite/interferometry-for-amateurs.pdf
[05:20:55] <toastydeath> i've always wondered why nobody has turned a cheapy lathe into an optics lathe
[05:21:02] <toastydeath> they're not that complicated
[05:23:31] <kwallace1> Optics lathe as in turning lenses?
[05:23:44] <toastydeath> yep
[05:29:43] <kwallace1> The tolerances are in the fractions of a wave length for telescopes, .. but maybe not for eyeglasses. I think eyeglass blanks are injection molded these days. I don't know how glasses where made when real glass was used. I guess it was then, what is like now, everything but babies comes from the store.
[05:30:22] -!- ve7it has quit [Remote host closed the connection]
[05:30:40] <t12> its weird once you start working with really small scale stuff
[05:30:51] <t12> you realize atoms arent exactly as small as you think
[05:30:51] <toastydeath> yep, and there are lathes that hold quarter wave accuracy over a one meter envelope
[05:31:01] <t12> like modern EMs can image single atoms
[05:31:03] <toastydeath> hydrogen wavelength
[05:31:11] <t12> have resolutions in the 2-3A range easy
[05:31:13] <toastydeath> er, not hydrogen, helium
[05:31:26] <toastydeath> 525 nm?
[05:31:57] -!- ve7it [[email protected]] has joined #linuxcnc
[05:32:08] <toastydeath> less accurate lathes aren't hard to build and get you in the ballpark really fast for aspheric optics
[05:33:02] <toastydeath> they're more optical roughing machines than finishing
[05:33:12] <toastydeath> some are accurate enough for finishing

[05:44:26] <toastydeath> haha, I would hope so
[05:46:37] <toastydeath> i'd really like to know how cnc lapping works, because I have things I'd like to do with cnc lapping
[05:48:26] <fenn> i thought you were the cnc lapping pro
[05:48:41] <kwallace1> This is closer to my budget:
http://www.mirror-o-matic.com/
[05:49:15] <toastydeath> me?
[05:49:16] <toastydeath> no way
[05:49:22] <toastydeath> i know nothing about cnc lapping
[05:49:46] <toastydeath> i have heard some lectures and read some papers on deterministic polishing, but that was a long ass time ago
[05:49:50] <t12> i scored a 3axis computerized microscope stage recently
[05:50:03] <t12> i wonder if it has enough torque to machine tiny things
[05:50:39] <toastydeath> i know a pretty good amount about ultraprecision machining and how that proceeds, and a good amount about lapping in general
[05:50:43] <toastydeath> but nothing about cnc lapping

[15:18:19] <Himanshu__> is it easy to write GUI using QT4?? i am developing Small Machine operating utility and AXIS is really heavy for that so i want to write my own GUI.. i am Good at C++... Axis is in python and i dont want to learn new language for small gui
[15:19:46] <Himanshu__> anyone here?? please reply

[15:34:52] <cpresser> Himanshu__: i am not sure if there is an QT-Binding. but you should take a look into other linux-cnc UIs. There is also 'emcsh' as a text-mode client. they all interface to linuxcnc via NML.
[15:35:45] <Himanshu__> that means if i can use NML in QT than i can write GUI right??
[15:36:03] <cpresser> yes.

[16:05:35] <spiderdi1on> What part do the fpga cards like the 5i20 actually play in the milling process, how are they actually utilised? I'm thinking of getting one to remove potential problems with jitter but I want to get a firm grasp in my head about how it actually achieves this.

[16:16:08] <cpresser> skunkworks: lirc is broken for most kernel-version :/
[16:16:46] <cpresser> but you might use "inputlircd" or "eventlircd"
[16:16:56] <cpresser> which are both userspace.
[16:18:12] <skunkworks> cpresser: thanks! Do you have any links?
[16:19:05] <skunkworks> spiderdijon: the mesa cards move the heavy liftiing out of the computer. (PWM, Step generation, encoder counting...)
[16:23:12] <cpresser> skunkworks: nope sorry. only google.
[16:23:46] <cpresser> unfortunately both of them have few documentation; i know some howtos, but all in german. sorry
[16:23:54] <skunkworks> Sheh
[16:23:56] <skunkworks> heh
[16:24:10] <cpresser> basically eventlircd replaces lircd.

[17:54:13] <IchGuckLive> how mutch RAM do you folks got on your ->Intel D525MW mini-ITX

[17:54:46] <jdh> 2gb in one, 4gb in the other.
[17:54:53] <jdh> 2 seems to be more than enough.
[17:54:55] <mhaberler> the 4GB which I just ripped out of my macbook
[17:55:18] <IchGuckLive> ok

[17:58:32] <IchGuckLive> i see there are now 2 mini itx atom D525 available one from intel and one from Gigabyte
[18:03:18] <mazafaka> What if you cut with the depth like 2 mm each time, and sharpen the tip of the end mill bit when it is needed, will you be satisfied with this tactics? Or you would prefer to program some pass for fining?
[18:03:41] <mazafaka> http://www.youtube.com/watch?v=UnKjIdlGXgQ&feature=plcp
[18:03:52] <IchGuckLive> mazafaka: material
[18:04:17] <IchGuckLive> it depends on shape and material
[18:05:09] <IchGuckLive> mashine also if not able to cut 10mm+ depth so no factor

[18:05:54] <mazafaka> IchGuckLive: steel, and maachine lacks rigidity if the end mill isn't sharp
[18:06:30] <IchGuckLive> if your mashine can hold climb 10mm go for it
[18:06:48] <mazafaka> we made a puncheon this way, I think what if we finally organise a cheap workflow using HSS end mill bits.
[18:07:19] <IchGuckLive> there are many cheep CO8 cutters around
[18:07:21] <mazafaka> No, 10mm for cutting height is too much.
[18:07:27] <IchGuckLive> you might be impressed
[18:07:51] <mazafaka> IchGuckLive: it is not me who is buying the stuff
[18:08:33] <mazafaka> I cut 2mm-deep passes, and the width of the cut equals to the diameter of the mill
[18:08:34] <IchGuckLive> 2mm seams very littel if it is a straigt shape to be milled
[18:09:05] <IchGuckLive> did you try 10 depth 3mm wide with a 10mm cutter
[18:09:11] <mazafaka> but the diameter of the mill bit is 3/4 inches
[18:09:18] <IchGuckLive> it makes better chips
[18:09:21] <mazafaka> IchGuckLive: i tried
[18:09:40] <IchGuckLive> the side is always better on standard steel
[18:09:44] <mazafaka> but... we have to take new end mill bit each 1.5 hours

[18:10:12] <mazafaka> it's tricky on a non-rigid machine
[18:10:27] <IchGuckLive> ok then go your way
[18:10:55] <syyl_ws> my trick on a non rigid machine is a roughing cutter :P
[18:10:59] -!- pjm__ [[email protected]] has joined #linuxcnc
[18:11:52] <mazafaka> the way you say i did some work on stainless steel where the tolerances were quite big. And then had to mix up something for a precise work. Now I need to know if it's common or not
[18:13:48] <IchGuckLive> i use CRC always so with one Rouph and on finish tool you are good
[18:14:09] <IchGuckLive> if the finish tool showes marks then you got a new rouphing tool
[18:14:26] <mazafaka> So, it's more common to add a fining pass using new and sharp end mill bit?
[18:14:42] <syyl_ws> jep
[18:14:48] <mazafaka> uhu!
[18:14:50] <IchGuckLive> yes
[18:14:51] <syyl_ws> or go always full depth
[18:14:54] <mazafaka> now i know!
[18:14:55] <syyl_ws> with the cutter
[18:15:03] <syyl_ws> and take shallow cuts to the side
[18:15:10] <syyl_ws> so it will wear even
[18:15:23] <IchGuckLive> i keep 0.2mm for the finish path in depth and wide
[18:15:23] <syyl_ws> thats a strategy i use very often
[18:17:17] <mazafaka> IchGuckLive: 0.2 mm in wide and full height, or how?
[18:17:30] <IchGuckLive> yes up to 500mm height
[18:17:34] <IchGuckLive> 50.
[18:17:57] <mazafaka> yeah, why not... if you have end mill bits... :)
[18:18:00] <IchGuckLive> stainless steel
[18:18:25] <IchGuckLive> my max is 225 mm in cutting height
[18:18:36] <IchGuckLive> FOAM O.O
[18:18:49] <mazafaka> I had 2 old already short 16mm end mills for 3 puncheons and 3 matrices
[18:19:21] <IchGuckLive> you need to calculate the tools into your price
[18:19:30] <IchGuckLive> special tools are full price
[18:19:42] <mazafaka> i know, but it's a plant.
[18:19:53] <IchGuckLive> even if
[18:20:03] <mazafaka> right now i'm going to another plant
[18:20:30] <IchGuckLive> but if you got your own sharpener then maybe heads first is better for you
[18:20:52] <IchGuckLive> but miling time also counts
[18:21:22] <IchGuckLive> mazafaka: where are you from USA Europ
[18:21:35] <mazafaka> yeah, sharpening of the tiny end bits takes time... I'm in Russia
[18:21:42] <psha> IchGuckLive: ru
[18:22:19] <mazafaka> I probably will work in formerly secret underground shop, I don't know...
[18:22:34] <IchGuckLive> russia then tool price shoudt be very low
[18:23:12] <mazafaka> We used HSS, and many delicious thingies on WFL.
[18:23:24] <IchGuckLive> polen tool manufactures sell 10mm co8 for less then 5 Eur
[18:23:46] <IchGuckLive> Ukrain do so 2
[18:23:56] <mazafaka> heh, i will know it now.
[18:27:52] <IchGuckLive> with a small 4 Axis cutter sharpener you can make money

[18:59:53] <Caanon_work> I'll check into awallin and opencamlib
[19:00:14] <IchGuckLive> there is also reprap a good thing for mesh plane issues
[19:00:18] <Caanon_work> IchGuckLive: I'm thinking more along the lines of what slic3r does or skein forge does
[19:00:26] <awallin> opencamlib is for 3-d milling with real milling tools. that is different from a pure "z-slice" where you do not care for the shape of the cutter
[19:00:41] <IchGuckLive> Caanon_work: there is the Master

[20:08:54] <gmouer> amplitude follows the speed commanded
[20:09:07] <cradek> are you in mm or inch?
[20:09:13] <gmouer> inch
[20:09:26] <gmouer> noise is around 27-30hz rate
[20:09:41] <cradek> tell us about your setup
[20:10:10] <JT-Shop> tjb1:
[20:10:18] <tjb1> JT-Shop: Yes?
[20:10:23] <gmouer> 7i77 mesa, servo dynamics drive, brushed servo, vel loop in drive, position loop in emc
[20:10:32] <JT-Shop> you get your homing sorted out?
[20:10:54] <gmouer> It tunes pretty normal but that noise shows up on the following error also
[20:11:36] <tjb1> cncbasher posted something but I cant try it until wednesday
[20:11:56] <gmouer> I am stumped what the cause of that noise is? tried filter caps on the dc power in to the 7i77 board, no effect
[20:12:01] <JT-Shop> are you trying to home more than one axis at a time with all sharing the same input?
[20:12:17] <cradek> I think you're jumping to the conclusion that it's noise
[20:12:42] <cradek> you could have oscillation in the velocity loop, or in the position loop, or you could have a mechanical resonance
[20:12:51] <andypugh> gmouer: PCW is of the opinion (I think, not wanting to put words into his mouth) that you will get better results tuning to minimise the PID error term than the f-error.
[20:12:52] <tjb1> No, one at a time
[20:12:56] <gmouer> that could well be !! Linuxcnc is new to me I am used to nice clean curve lines on servo displays
[20:13:11] <cradek> how did you tune the velocity loop?
[20:13:48] <gmouer> first tuned the velocity loop open loop, by the manual for the drive, that seems to behave normal, (no noise)
[20:14:08] <cradek> do you hear this disturbance in the machine motion? what does it sound like?
[20:14:08] <gmouer> but it was a low speed where the noise is much lower
[20:14:18] <gmouer> no, the machine is smooth
[20:14:21] <JT-Shop> bbl
[20:15:02] <gmouer> I have searched around and not seen this on other halscope plots I found
[20:15:04] <cradek> that's hard to believe with velocity varying 0.3ish inch/sec
[20:15:34] <cradek> it always sounds smooth, even when making this plot you shared?
[20:16:29] <gmouer> yes, smooth during that plot, my only concern is it showing in the following error, wouldn't know it was happening if not for halscope
[20:16:57] <cradek> you didn't show following error on the plot...
[20:16:59] -!- pcw_home [[email protected]] has joined #linuxcnc
[20:17:25] <cradek> I have a hard time understanding how it can sound smooth. is it a heavy/light/big/small machine?
[20:17:33] -!- L84Supper has quit [Quit: <puff of smoke>]
[20:17:37] <gmouer> yes, I left the following error out for now, I have things detuned attempting to see if I could impact that "noise" which I could not
[20:18:29] <gmouer> It is a omniturn lathe, I would class it bewteen small and medium, its a 5c collet type machine, linear rails,
[20:18:56] <cradek> ok, so you're not moving much mass
[20:19:08] <cradek> how about if you put your hand on it while it's moving? can you feel the disturbance?
[20:19:20] <gmouer> right, very little mass, maybe 10-20 lbs tops
[20:19:45] <pcw_home> If you set P,I,D to 0 do you still get the noise?
[20:20:55] <gmouer> pcw: I tuned P way down to a min that would move the motor, it lowers the noise but does not eliminate it
[20:21:17] <gmouer> My I and D are at 0, vel loop in the drive, pos loop in linuxcnc
[20:21:30] <pcw_home> the motor should mainly be moved by FF1
[20:22:12] -!- L84Supper [L84Supper!~Larch@unaffiliated/l84supper] has joined #linuxcnc
[20:22:19] <pcw_home> so you should get approximate motion (and some drift) with PID = 0
[20:22:24] <gmouer> I am a novice at tuning, but yes, FF1 has a substancial effect in lowering the following error
[20:23:02] <pcw_home> FF1 is the principle term in a velocity mode loop

[20:24:05] <pcw_home> inch scale?
[20:24:12] <gmouer> yes, inch
[20:24:37] <gmouer> I had adjusted ff1 to center the following error above and below zero
[20:25:08] <pcw_home> does setting P to 0 eliminate the noise?
[20:25:14] <gmouer> I get a good following error at low speeds, but it goes to hell fast as speed increases
[20:25:23] <gmouer> I will try P=0 right now
[20:25:31] <gmouer> machine is next to me
[20:25:37] <cradek> until you've verified your velocity loop doesn't oscillate, you can't tune the position loop
[20:25:46] <pcw_home> (warning it will drift)
[20:26:28] <cradek> oh I see what pcw is doing: FF1 only will let you move it at various speeds
[20:26:38] <pcw_home> Thats why I am suggesting "opening the PID loop" by setting P,I.D to 0
[20:26:43] <cradek> gotcha
[20:27:37] <gmouer> no, with p=0 the noise is there but very slightly less in amplitude
[20:27:54] <gmouer> FF1 still set at about 3.0
[20:28:00] <cradek> then you can stop trying to tune the position loop...
[20:28:48] <cradek> you might have a noisy tach, or a periodic mechanical binding, or a badly tuned amp
[20:29:10] <gmouer> so right now, the guess is the noise is within the velocity loop?
[20:29:10] <cradek> but can you feel it when you put your hand on the axis?
[20:30:03] -!- tjb1 has quit [Quit: tjb1]
[20:30:13] <cradek> if it really does sound and feel smooth, you might have bogus position feedback
[20:30:18] <pcw_home> Yeah, could also be some kind or input connection/ground loop error (assuming you are misreading 60Hz as 30Hz)
[20:30:21] <gmouer> mechanical binding for a second..... there are 2 1 inch dia springs that retract the way covers, quite a bit of tension on those springs, more as you go towards Z0
[20:30:22] <cradek> no guessing, still troubleshooting
[20:31:10] <gmouer> the amplitude of that noise varys directly with speed, it reached 1.5 v p-p at 100 ipm
[20:31:29] <gmouer> (on the 10V analog control line)
[20:31:29] <cradek> frequency always the same?
[20:31:44] <gmouer> yea, around 27-30hz
[20:31:56] <cradek> you've seen that on a real wired scope?
[20:32:04] <gmouer> no, on halscope
[20:32:16] <cradek> you said "the analog control line"
[20:32:38] <cradek> you meant the commanded dac value?
[20:32:41] <gmouer> yes, I lied, analogout2 signal
[20:33:09] <cradek> with only FF1 there is no reason you should see any variation on that commanded dac value. are you sure??
[20:33:25] <gmouer> let me recheck
[20:34:21] <gmouer> yes, its on hm2....analog2 signal, about .7V p-p
[20:34:46] <cradek> but that makes no sense. you are making a mistake somewhere.
[20:34:57] <cradek> while jogging a constant speed, right?
[20:35:09] <gmouer> yes, a g01 command at 50 ipm
[20:35:15] <gmouer> one inch move
[20:35:33] <gmouer> noise is present during entire move, also on longer moves
[20:35:36] <cradek> you are maybe not changing the right pid values?
[20:35:43] <pcw_home> Yeah that should just be a trapezoidal velocity signal
[20:36:32] <gmouer> its the right pid values, if I crank P up a lot it goes into oscillation
[20:36:55] <cradek> did you zero out I, D, etc? everything but FF1?
[20:37:11] <gmouer> I and D have been at zero all along
[20:37:37] -!- gurumelo has quit [Remote host closed the connection]
[20:37:42] <gmouer> I does not have any great effect, D is not liked at all, very bad things happen
[20:38:15] <pcw_home> D is normally not needed for a velocity loop (the drive does 'D')
[20:38:19] -!- wavesounds has quit [Remote host closed the connection]
[20:38:21] <gmouer> pcw: what should be a trapezoidal velocity signal? where should that be seen?
[20:38:25] <cradek> you are making a mistake somewhere but I am not sure what it could be :-/
[20:39:08] <pcw_home> 'I' should not be tuned normally until everything else is very close
[20:39:09] <gmouer> I have tuned other servos but seen clean plots without all that noise
[20:39:57] -!- kwallace has quit [Ping timeout: 268 seconds]
[20:39:58] <gmouer> pcw, yes, tuning the pos loop it behaves like you would expect, its just that noise translates into following error
[20:40:31] <pcw_home> Are you saying that you see 30 Hz noise on the analog out as viewed in halscope?
[20:40:55] <pcw_home> (with only FF1 in the PID loop)
[20:40:57] <gmouer> as a note, I played with the tach and gain on the drive pcb last night, no effect on that noise
[20:41:34] <gmouer> yes, 20hz noise on analogout2, as shown on the halscope plot
[20:41:43] <gmouer> opps, 30hz noise
[20:42:09] <gmouer> nothing, adjustment wise, seems to effect that noise
[20:42:20] <gmouer> other than speed
[20:42:33] <gmouer> the noise is proportional to speed
[20:42:36] <pcw_home> OK so thats all internal, not related to 7I77, analog.tachometer,
[20:42:43] <pcw_home> etc
[20:42:59] -!- kwallace [[email protected]] has joined #linuxcnc
[20:43:02] <asdfasd> gmouer some things may cause that kind of noise, like crack in glass encoder for example
[20:43:21] <cradek> no, not with P,I,D=0
[20:43:28] -!- Caanon_work has quit [Quit: Caanon_work]
[20:43:34] <cradek> there is no feedback in the equation
[20:43:50] <cradek> that's why this doesn't make sense yet
[20:43:56] <pcw_home> can you edit the hal file and verify that the PID values are 0? this really make no sense
[20:44:01] <asdfasd> I see
[20:44:13] <pcw_home> makes
[20:44:22] -!- gurumelo has quit [Client Quit]
[20:44:50] <alex_joni> or use halmeter to look at the actual values
[20:45:01] <cradek> are you positive you are watching the dac output value, not the feedback velocity?
[20:45:04] <gmouer> it was setup initially with pncconf, the PID values in hal originate in the INI file, I can change them there if you want, I have been using the calibration window so far
[20:45:40] -!- wboykinm has quit [Remote host closed the connection]
[20:46:01] <alex_joni> calibration window.. eww ;)
[20:46:10] <gmouer> watching on the halscope display hm2......analogout2 and hm2 encoder2 velocity (f error off for the moment)
[20:46:43] <gmouer> want me set pid to zeros in the ini file and reboot?
[20:47:13] <cradek> you could check them with halmeter (or halcmd show) like alex suggested
[20:47:30] <cradek> when in doubt, troubleshoot, don't shoot in the dark
[20:48:00] <cradek> something is not working how you expect - we should find out what
[20:48:07] <gmouer> ok, I will check them with halmeter brb
[20:48:30] <alex_joni> and remember, a reboot is seldom the answer
[20:49:00] <cradek> restarting linuxcnc would be enough after editing the ini.

[20:52:08] <syyl> just for the video that slow
[20:52:14] <syyl> later i went with 1000mm/min
[20:52:20] <cradek> ok, something is confusing the calibrate app
[20:52:35] <gmouer> I will change P to zero in the ini file and restart linuxcnc
[20:52:37] <cradek> what linuxcnc version is this?
[20:53:24] <cradek> syyl: awesome
[20:53:43] <gmouer> 2.6 pre, master
[20:53:57] <cradek> oh dear
[20:54:25] -!- vladimirek has quit [Remote host closed the connection]
[20:54:53] <cradek> currently, master is MUCH more untested/untrusted than usual
[20:55:09] <cradek> do you have a strong reason to use it?
[20:56:28] <pcw_home> Thats neat syyl
[20:56:41] <gmouer> some of the pncconf fixes are there along with remap fixes for front/rear tool remap
[20:57:01] <cradek> oh ok
[20:57:22] <gmouer> I was under 2.5 originally and seen the same servo behavior
[20:57:53] <gmouer> I put it off till later, later is now, all is done except for servo tweaking
[20:58:18] <cradek> I was wondering whether the calibrator was broken in 2.5
[20:58:34] <cradek> most likely it's an incompatibility with pncconf-generated configs :-/
[20:58:36] <gmouer> it appears that with P=0 I get a following error quickly, I have Ferror set to 1/4 inch while tuning
[20:59:11] <cradek> that's not surprising. but is it smooth?
[20:59:11] <pcw_home> Sure but does it oscillate?
[21:00:06] <gmouer> can't really tell, it only moves 1/4 inch, I will turn the f error up and look at the halscope plot
[21:00:34] <cradek> I hope you verified your limit switches already
[21:00:55] <pcw_home> Its should not be terribly bad if you have FF1 right
[21:01:08] <cradek> ... and your travel to them is unobstructed
[21:03:58] <gmouer> encoder02 velocity has the noise, analogout2 is extremely clean
[21:05:26] -!- mazafaka has quit [Read error: Connection reset by peer]
[21:06:34] <pcw_home> so tach/drive/encoder/analog interface issue
[21:06:53] <gmouer> ok, I am following you
[21:07:18] <pcw_home> can you feel the vibration?
[21:07:32] -!- djheinz has quit [Ping timeout: 255 seconds]
[21:08:15] <gmouer> that is hard to say, those big springs under the slide that hold the way covers make noises and do "twang" things
[21:08:25] <gmouer> still, I would say it moves pretty smooth
[21:09:17] <gmouer> its something you hear more than feel. I tore the whole thing apart being concerned only to find it was those springs making the noises, not the linear rails or ballscrew
[21:09:52] <gmouer> they are those telescoping metal way covers
[21:10:06] <pcw_home> to isolate interface vs tach/drive/encoder issues
[21:10:08] <pcw_home> you can try driving it either way with a battery
[21:10:10] <pcw_home> (are you really really sure its 30 Hz and not 60 Hz?)
[21:11:05] <gmouer> yea, I was hoping for 60hz, a open shield or such, the halscope peroid calcs out to 27-30hz area
[21:12:01] <gmouer> roughly 33 ms
[21:12:11] <pcw_home> well sure sounds like drive/tach issue
[21:12:32] <gmouer> with your troubleshooting help, it certainly points that way
[21:13:31] <gmouer> I am thinking to unhook the servo coupling to the ballscrew, and use a battery for the control voltage and see what it looks like then
[21:13:44] <pcw_home> you can also use the 7I77 DAC to generate a step velocity signal for tuning the velocity loop
[21:14:39] -!- joe9 has quit [Quit: leaving]
[21:14:47] <pcw_home> (well the PID loop with just FF1 will do that as well if accell is turned up high)
[21:14:56] <gmouer> this lathe only has 5" travel in the Z so it would get hairy without a position loop
[21:15:11] <andypugh> Be aware that with the motor unconnected to the rest of the machine it will be harder to tune.
[21:15:54] <gmouer> andy: yes I have seen that before, but a final tune is not the goal, only finding the source of that noise/oscillation
[21:16:55] <gmouer> pcw: the accel is pretty mild, set at 15 right now, inch units
[21:17:00] <gmouer> its a linear rail machine
[21:18:12] <pcw_home> Just saying ts a easy way to tune the velocity loop by just changing some parameters
[21:18:59] <gmouer> oh, ok, for tuning, I thought you were talking a high accel
[21:19:32] <gmouer> "Will do that" speaking in ref to the noise
[21:19:40] <pcw_home> (If accell is set high, a jog will output what loots like a step in velocity to the drive)
[21:19:42] <pcw_home> so you can tune the drives response for no overshoot/oscillation
[21:19:42] <gmouer> I understand now
[21:20:13] <pcw_home> just a lazy way to generate a step

[21:22:12] <gmouer> well, fellows, I guess our work is done for now, I have to troubleshoot in the drive/tach area searching for the cause of that oscillation
[21:22:50] <gmouer> thanks much guys, I knew you guys would get me on the right track to finding the cause
[21:23:05] <gmouer> plus, I wanted to confirm that it was not normal
[21:23:33] -!- amaldo has quit [Remote host closed the connection]
[21:25:27] <pcw_home> no, un-responsive oscillations are not the norm (but anythings possible on a unknown machine)
[21:35:44] <cradek> if it sounds and feels smooth, it still might be bogus position feedback.
[21:36:26] <cradek> a real scope on the real tach might be useful (use differential mode on the scope, don't short out your tach circuit)

[21:43:23] <JT-Shop> the touch off button
[21:44:04] theorb_ is now known as theorbtwo
[21:44:09] <Aero-Tec> would I do a tool change to tool 1 as it is the zero for all others and write down the off set numbers?
[21:44:35] <Aero-Tec> so the touch off will load info into the tool table?
[21:44:49] <JT-Shop> yes

[22:20:10] <andypugh> What _is_ .plt?
[22:20:34] <djheinz> its a HP, plotter file format...
[22:21:00] <Loetmichel> HPGL
[22:21:08] <andypugh> Yes, I thought it might be HPGL
[22:21:13] <Loetmichel> djdelorie: corel draw can
[22:21:20] <Loetmichel> sorry
[22:21:29] <djheinz> it can?
[22:21:58] <Jymmm> Yep
[22:22:00] <Loetmichel> djheinz: corel draw, BoCNC, and any program that can drive a HP 75** plotter ;-)
[22:23:10] <andypugh> You will probably find that print-to-file with the printer set to pen plotter will work. Or Use Graphic Converter (Mac)
http://www.lemkesoft.com to convert other things into it.
[22:23:36] <t12> djheinz: coreldraw

[22:23:48] <t12> i coulda read that heh
[22:23:54] -!- pjm [[email protected]] has joined #linuxcnc
[22:24:06] <andypugh> djheinz: Inkscape doe HPGL
[22:24:15] <t12> you can also pretty trivially write out hpgl sans-curves via javascript in illustrator
[22:24:42] <t12> theres also a few windows printer drivers
[22:24:47] <t12> that will output hpgl
[22:24:48] <andypugh> That code I linked earlier converts STL to HPGL :-)
[22:25:03] <t12> and apparently some of the older designjet drivers can too
[22:25:11] <t12> though i've never really got that to work
[22:25:25] <t12> my expirence is that theres alot of dialects of hpgl also that some devices like/dontlike
[22:26:10] <andypugh> I used it to slice STL into sticker paper layers to make:
https://picasaweb.google.com/lh/photo/tjht3D69CSp25i9tYwD7dtMTjNZETYmyPJy0liipFm0?feat=directlink using my Mac and a pen-plotter.
[22:27:32] <andypugh> But, of all the suggestions, I reckon Inkscape is the most free and cross-platform, and it can export G-code too with the right plug-in.
[22:28:44] <Loetmichel> t12: thats why corel draw for example uses only "PU" "pD" and "ST"
[22:30:18] <djheinz> hmm
[22:31:09] <Loetmichel> ... has the drawback of some facettes on circles, if the adjustments are not fine enough in the exporter
[22:31:48] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12527
[22:31:58] <djheinz> is HPGL the SAME as PLT?
[22:32:09] <Loetmichel> it is
[22:33:01] <djheinz> so it works to just rename?
[22:34:32] <Loetmichel> if the interpreter can read the special hpgl: yes
[22:34:53] <Loetmichel> like t12 saidf: hpgl ist necessarily like hpgl
[22:35:16] <Loetmichel> there are nearly as much variants outside as it had plotters in the old days.

[23:05:52] <Loetmichel> mostly for glass fibre plastic/carbon fibre plastic, some plywood and some aluminium sheets
[23:05:55] <Aero-Tec> why would the Gcode quick reference show a error?

[23:07:07] <Aero-Tec> also in the instruction for setting tool table with touch off it says to
[23:07:09] <Aero-Tec> Verify that Machine > Touch off to fixture is selected.
[23:07:13] <Loetmichel> http://www.cyrom.org/hajo/09_01_09.avi <- That was a day at the old company
[23:07:47] <Aero-Tec> there is no Touch off to fixture that I can find

[23:11:16] <Aero-Tec> JT-Shop: you around?
[23:11:24] <Aero-Tec> back from walking the dog?
[23:11:26] <JT-Shop> yup
[23:11:29] <Aero-Tec> cool
[23:12:03] <Aero-Tec> I had asked some questions and was hoping for a answer
[23:12:13] <Aero-Tec> if you can help that would be great
[23:12:43] <JT-Shop> depends on the question if I can help or not :)
[23:12:57] <Aero-Tec> why would the Gcode quick reference show a error?
[23:13:09] <Aero-Tec> also in the instruction for setting tool table with touch off it says to
[23:13:18] <Aero-Tec> Verify that Machine > Touch off to fixture is selected.
[23:13:25] <Aero-Tec> there is no Touch off to fixture that I can find
[23:13:55] <JT-Shop> it is in the machine menu at the bottom
[23:14:13] -!- tjb1 [[email protected]] has joined #linuxcnc
[23:14:26] <Aero-Tec> there is a menu at the bottom?
[23:14:27] <JT-Shop> are you using the Axis GUI?
[23:14:34] <Aero-Tec> yes
[23:14:50] <Aero-Tec> I had not seen it
[23:14:54] <JT-Shop> look
[23:14:57] <Aero-Tec> will look
[23:14:59] <Aero-Tec> lol
[23:15:02] <Aero-Tec> will do
[23:15:16] -!- joru has quit [Remote host closed the connection]
[23:15:50] <Aero-Tec> also why would the Gcode quick reference bring up a error message?
[23:16:01] <JT-Shop> what error?
[23:16:20] <Aero-Tec> will have to look at it

[23:21:16] <Aero-Tec> but nothing that looks like a menu
[23:22:01] <Aero-Tec> JT-Shop: the error is no such file or dir
[23:22:05] <JT-Shop> the Machine Menu item
[23:22:44] <JT-Shop> the gcode quick referenc uses some smoke and mirror magic that does not always work, just use the user manual
[23:23:15] <Aero-Tec> the top has File Machine View Help
[23:23:27] <Aero-Tec> ok
[23:23:30] <Aero-Tec> will do
[23:23:51] <Aero-Tec> is not the machine menu at the top?
[23:23:57] <Aero-Tec> it look like it is
[23:24:01] <JT-Shop> yep Machine is the winner
[23:24:02] <Aero-Tec> looks
[23:24:11] <JT-Shop> click on it and look at the last item
[23:24:50] <Aero-Tec> it may be the winner but has nothing that is Touch off to fixture
[23:25:06] <Aero-Tec> I did meny time and there was no Touch off to fixture
[23:25:21] <JT-Shop> what version of LinuxCNC are you using
[23:25:39] <Aero-Tec> the new one I think
[23:25:45] <Aero-Tec> can look
[23:26:04] <JT-Shop> it is there then
[23:26:05] <Aero-Tec> 10. something if mem serves

[23:26:25] <Aero-Tec> will check the version number

[23:32:42] <Aero-Tec> JT-Shop: looks like it is 8.04
[23:32:50] <Aero-Tec> axis 2.4.6
[23:33:03] <Aero-Tec> Gnome 2.22.2
[23:33:07] -!- jp1 [jp1!~androirc@CPEf07bcb8dc98f-CM001bd71cb794.cpe.net.cable.rogers.com] has joined #linuxcnc
[23:33:58] <JT-Shop> 2.5.1 is the latest version and you can install that on 8.04
[23:34:33] <Aero-Tec> how does one install it?
[23:34:42] <Aero-Tec> I have done the updates
[23:35:01] <Aero-Tec> would it not have been updateded with the auto updates?
[23:35:23] <Aero-Tec> guess not as it is not updated
[23:36:18] <Aero-Tec> should I update the system to the latest version as well?
[23:36:35] <Aero-Tec> if so is that hard to do?
[23:37:17] <JT-Shop> LinuxCNC will not update from 2.4 to 2.5 automagiclly
[23:37:40] <Aero-Tec> sorry for being such a noob at all this
[23:37:46] <JT-Shop> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?UpdatingTo2.5
[23:38:06] <JT-Shop> everyone is a nubee when they start it is expected
[23:38:57] <andypugh> Upgrading from 8.04 to 10.04 runs the risk of making your machine run worse, so just upgrade LinuxCNC nor Ubuntu unless there are things in 10.04 that you really want.
[23:38:57] <Aero-Tec> thanks
[23:39:15] <Aero-Tec> my computer is a intel P4
[23:39:32] <andypugh> Stick with 8.05 then.
[23:39:34] <JT-Shop> better stay with 8.04 on a P4
[23:39:36] <andypugh> 8.04 even
[23:39:42] <JT-Shop> hey that rimes
[23:40:45] -!- racycle has quit [Quit: racycle]
[23:43:20] <andypugh> Well, there is something I didn't know. Native in-the-code units of LinuxCNC are mm.
[23:48:03] <JT-Shop> well there you go, all this time you assumed EMC was imperal
[23:48:46] <cradek> except for in AXIS, insanely enough
[23:50:17] <JT-Shop> LOL
[23:50:38] <jp1> axis = imperial touchy = jedi
[23:50:41] <andypugh> Yes, that does seem a little crazy. But then Axis is crazy. It's almost a pity it works so well.
[23:51:23] <cradek> agreed.
[23:51:30] <andypugh> Tcl is number 71 in a popularity list which has APL as 31...
[23:51:48] -!- L84Supper has quit [Ping timeout: 245 seconds]
[23:51:53] <cradek> yes but which popularity list is the most popular?
[23:52:30] <cradek> reminds me of seb's suggestion that we make a wiki page listing the most out-of-date wiki pages
[23:52:46] <andypugh> Depends if you ask John Ousterhout or anyone else :-)
[23:52:58] <JT-Shop> if that page gets out of date does it make the list
[23:53:18] <SWPadnos> ?PARSE ERROR
[23:54:03] <cradek> my ex who worked in insurance IT said their actuaries were still using APL, ca 200x. it might be the best tool for some jobs...
[23:54:12] <cradek> ?REDO FROM START
[23:55:09] <jp1> anyone know if the 7i77 manual is up to date? seem to remember an issue with the spindle terminals
[23:55:11] <SWPadnos> I wonder what the difference would be between these "most popular" lists: most programs using a language, most people wanting to use a language, most programs still running which were written in a language
[23:55:27] <cradek> SWPadnos: big, would be my guess
[23:55:41] <SWPadnos> yeah, I was thinking that
[23:56:05] <cradek> SWPadnos: those lists are generally about what language geeks find cool right now
[23:56:29] <SWPadnos> sure. the revision history of such a list would also be interesting :)
[23:56:29] <JT-Shop> jp1: the online manual is up to date
[23:56:33] <cradek> SWPadnos: another useful list would be what languages to learn to support yourself in a useful way
[23:56:51] <SWPadnos> "which languages will be the most popular in the future" ...
[23:57:15] <cradek> that's just a list that helps you troll
[23:57:40] -!- L84Supper [L84Supper!~Larch@unaffiliated/l84supper] has joined #linuxcnc
[23:57:54] <andypugh> Well, this was the list in question, I think it is based on sourceforge projects:
http://lang-index.sourceforge.net
[23:57:59] <jp1> jt-shop: thanks
[23:58:03] <cradek> a language geek at work has been recently raving about "native code" i.e. compiled languages, because they use less battery power on mobile devices
[23:58:13] <SWPadnos> heh
[23:58:16] <JT-Shop> np
[23:58:29] <cradek> shortly before (of course): CPU is free - use interpreted languages
[23:58:53] <cradek> all of a sudden, oh hell, efficiency matters
[23:59:22] <SWPadnos> that would be an interesting benchmark - power usage to run XYZ algorithms or whatnot, per language
[23:59:34] <andypugh> APL and Matlab are together, and both are great for vectorised data.
[23:59:55] <cradek> SWPadnos: probable result: use C
