[01:08:39] <eric_unterhausen> I ordered some extrusion that was 450mm long and there is a warning that it might go out on a truck
[01:09:00] <eric_unterhausen> and the extrusion that is 750 mm long has no such warning

[08:01:25] <false> Hey all
[08:01:44] <kengu> hey you
[08:01:57] <false> I have a question, or actually a couple :P.
[08:07:06] -!- i_tarzan has quit [Ping timeout: 264 seconds]
[08:07:27] <ReadError> you may have 1!
[08:09:06] <false> I am in the process of retrofitting an old Matsuura MC710V, I am using Mesa cards (2x 7i33, 1x 7i37). I am reusing the drives which are old fanuc velocity drives with tach input (using the second 7i33 as tach output to drives). Now for the first question, is it normal for the servo to drift when I use the following: P0 I0 D0? I have shorted the analog and tacho to ground on the drives to
[08:09:06] <false> correct for 0 drift on the drive. I also tried to get the 7i33 outputs as close to zero as I can, within 0.0015V. But when I connect the drives to the 7i33 with those pid parameters and enable the drives the servo starts to drift.

[08:17:04] <false> And the second (sorry I need more than one :P), if I use a Pgain of more than 0.5 and jog at low speed (250mm/m) the axis oscilates violently to the point where the fuses blow or the drives go into overload, I am seeing way higher numbers on other configs, is there something I am missing?
[08:19:19] <false> I've followed the tutorial on tuning velocity drives but I can't set my Pgain high enough to correct for initial following error.

[08:24:04] <cncbasher> anyone running camview on development as run in place , i find the onscreen dro's work fine on installed 2.5.3 , but emc.halio plugin fails when used on dev and run in place
[08:29:03] Cylly is now known as Loetmichel
[08:30:24] <archivist> cncbasher, been some chatter on the mailing lists with mention of emc.halio
[08:31:05] <archivist> not deeply following as I dont run camview
[08:31:33] <cncbasher> yes i have seen it and thats what prompted me to look further
[08:32:17] <Valen> false: the numbers are irrilivent
[08:32:31] <Valen> also if you are metric vs inches i believe they will be very different
[08:32:49] <cncbasher> i presume it's linking to installed version
[08:33:33] <Valen> i don't know about velocity drives in paticular but generally set P higher and higher till it oscilates then back it off by 1/3rd
[08:33:59] <Valen> add some ff1 to null out any fixed offset (this could be different with a velocity drive)
[08:34:02] <false> Valen: Increase while idle, and don't try to move the axis?
[08:34:06] <Valen> add some I and a little D
[08:34:12] <Valen> move the axis around
[08:34:16] <Valen> slow and fast
[08:34:41] <Valen> my P is like 3 on one axis and 5 on another
[08:35:03] <Valen> also make sure your deadband is larger than an encoder count
[08:35:13] <Valen> otherwise I will build up and make it oscilate
[08:35:29] <false> Ok, I'll go and try those, thanks!
[08:36:07] <false> Did you happen to see my first question to?
[08:36:46] <Valen> if you have no correction random noise and offsets will make it drift
[08:37:26] <false> Ok, thought that was it, but wanted to make sure before I try to tuning something that isn't correct in the first place
[08:37:50] <Valen> i think there is a "bias" term you can put in to correct that?
[08:39:32] <false> I'm going to try again, thanks for your help!

[13:33:22] <pcw_home> also is this a MM or inch machine? (mm machines will have P gains lower by a factor of 25.4 if not normalized)
[13:33:39] <cradek> you don't have real tachs?
[13:33:48] <false> Yes it is a velocity drive (fanuc a06b-6035-h422)
[13:33:53] <false> mm
[13:34:12] <false> No tachs, they were not on the motors and were provided by the NC board
[13:34:24] <jthornton> http://gnipsel.com/linuxcnc/tuning/index.html
[13:34:42] <false> It used a f/v converter to generate tach from encoder input

[13:35:09] <false> Jthorton: I tried using that, but it did not get me anywhere unfortunatly
[13:35:26] <false> No the tach was 6v/1000rpm
[13:35:52] <false> the tach is giving the correct output and is stable

[13:37:42] <false> I also measured the outputs when the orignal NC board was still connected, then simulated a turning encoder using a mpg wired to the encoder input of the 7i33, the tacho output was correct

[13:40:35] <false> pcw_home: what do you find suspicious about this, could this be a hint as to what is causing the issue?
[13:45:06] <false> I was thinking that the drives may be configured in torque mode, but this seems not logical as the board need a VMCD (as opposed to TCMD) and a torque mode drive doesn't need tacho's right?
[13:45:11] <pcw_home> A velocity mode drive needs no D
[13:45:39] <false> Ok, I will set D=0
[13:45:44] -!- Chem2 [Chem2!~mwmitman@] has joined #linuxcnc
[13:45:49] <pcw_home> large static errors say torque mode to me
[13:46:39] <pcw_home> so something about the velocity feedback is not working (possibly backwards?)
[13:47:11] -!- Chemeleon has quit [Ping timeout: 246 seconds]
[13:49:50] <pcw_home> if they are smaller motors an you can decouple them you should be able to feel the
[13:49:51] <pcw_home> velocity feedback with 0 commanded velocity and PID = 0
[13:49:53] <pcw_home> (it should attempt to hold the shaft still if you turn it, though it may creep slowly)
[13:52:08] <false> Feedback is correct, it is inverted. The drive uses a vcmd of 7v/1000rpm and a tsa (tacho) of 6V/1000rpm but a positive command must generate a negative tacho signal, otherwise servo runs away at full speed. The servo is working correctly but I cannot get the tuning right

[13:53:26] -!- Logi has quit [Ping timeout: 256 seconds]
[13:54:00] <pcw_home> So you are simulating the tachometer with a 7I33 channel?
[13:54:09] <false> Yes that is correct
[13:54:48] <pcw_home> and the 7I33 velocity out scaling is correct?

[13:57:02] <false> When using the above tuning the static error goes away when moving the axis but it returns when I stop moving
[13:57:36] <false> So the PID is correcting the error

[14:02:24] <false> 0.0775Volts
[14:02:45] <false> thats strange?
[14:04:01] <false> shouldn't that be zero?
[14:04:04] <pcw_home> well 77 mv should make it move
[14:04:55] <pcw_home> there will be some offset but it should be maybe 1/10 or or less
[14:05:41] <false> It isnt moving, I watched hm_5i20.0.encoder.[z].count and its dead quiet
[14:06:24] <false> I tuned the drive for 0 drift with the analog and tacho shorted to ground.
[14:06:58] <pcw_home> tune for 0 drift when the drives are enabled and connected to the 7I33
[14:07:48] <false> funny story, when the 7i33 is connected the offset potmeter does not have any effect, could the 0.0775V be to much to correct with the offset potmeter?
[14:08:47] <pcw_home> when the 7I33 is connected you must disable the PID loop to make this adjustment
[14:10:08] <false> So I must enable the 7i33 outputs + drive, and disable the pid loop?
[14:11:08] <false> That makes sense, the loop is just correcting the offset adjustment I am making, correct?
[14:11:17] <pcw_home> Yes (it will not drift if the PID loop in working)
[14:12:00] <false> Ok I'll go and do that, thanks for your help Peter!

[14:28:10] <false> Again no response from the offset potmeter, the tacho out is responding to the moving axis so the drive is getting a tacho feedback, with the PID disabled the 7i33 output is at .0244V
[14:29:18] <false> I should offset this to as close to 0 as I can get right, but still very strange the offset potmeter is not doing anything. The drive does respond when analog an tacho are shorted to ground
[14:29:38] <pcw_home> wiring problem?
[14:31:12] <pcw_home> does the drive have differential inputs?
[14:31:40] <false> All shielded twisted pair separate for each signal, shield terminated at the 7i33. Connecting a 1.5V battery to the drive's analog in the drive responds as it should.
[14:32:05] <pcw_home> but does the drive have differential inputs?
[14:32:24] <false> Unfortunatly, no
[14:32:33] <pcw_home> Yuck
[14:32:35] <false> common ground
[14:32:39] <false> yep
[14:33:29] <false> sorry didnt catch your question the first time
[14:33:40] <pcw_home> sure you have the PID /velocity feedback disabled?
[14:34:07] <false> all set to zero
[14:34:38] <false> i can comment out the following to be sure: net x-enable => pid.x.enable??
[14:34:39] -!- ravenlock has quit [Ping timeout: 276 seconds]
[14:35:28] <pcw_home> Yes
[14:35:36] <false> Ill do that
[14:35:44] <pcw_home> how is the velocity feedback wired in hal?
[14:37:20] <pcw_home> it should be something like: mumble.encoder.n.velocity --> mumble.pwm.value
[14:38:24] <false> net y-tacho-out <= scale.tacho-y.out => hm2_5i20.0.pwmgen.04.value

[14:39:45] <false> net y-vel-fb <= hm2_5i20.0.encoder.00.velocity
[14:40:11] <pcw_home> OK so a scale comp in between (though PWM scale should do)
[14:40:37] <false> yes i tried the pwm scale but it didnt work, probably me doing it wrong
[14:41:17] <pcw_home> it should (and you can use a negative sale to reverse the output)
[14:41:27] <pcw_home> negative scale

[14:44:37] <false> correction the scale is not set negative, but the encoder is
[14:47:22] <pcw_home> well the encoder scale needs to be set to get the correct axis readout
[14:47:24] <pcw_home> (though its probably better to swap encoder leads)

[14:48:30] <false> I will do that when everything works, the problems was the encoder connector was repaired and connected the wrong way around. So that caught me by suprise (runaway)

[14:49:24] _BJFreeman is now known as BJfreeman
[14:50:02] <pcw_home> at least if you get the drive enables and encoder working first, linuxcnc can catch them
[14:50:33] <false> Yes indeed
[14:51:06] <JT-Shop> unless you turn the ballscrew by hand first and verify the direction is correct
[14:52:02] <false> I knew the polarity of the orignals so i checked them first, but assumed after 2 encoders the 3rd would be the same, it was kind of hard to reach
[14:52:52] <false> I should have been the same but the repairman had switched the A and B channels
[14:53:14] <pcw_home> Yes you can also disable the drive and see the that the analog output voltage changes in such a way as to resist the motor shaft motion
[14:53:51] <false> I will go and try some more things, brb

[17:53:06] <andypugh> AHoy!
[17:54:52] <archivist> so I went hunting for the maths, found some, stuck it in some php... http://www.archivist.info/gear/designbevel.php
[17:55:56] <andypugh> That's a bit over-zealous :-)
[17:56:27] <archivist> there is still some missing though
[17:57:06] <andypugh> Do you think it is possible to generate bevels with spiral hobs and CNC?
[17:57:22] <archivist> no
[17:58:13] <skunkworks> heh - are you sure? ;)
[17:58:16] <archivist> the faster machines use two spindles on a taper path
[17:59:31] <archivist> reasonable sure for straight bevels, I am ignoring hypoid
[17:59:48] <andypugh> There is a simplified type that uses formed tools and two cuts to get the taper. I guess the problem is that a spiral hob doesn't generate the correct form?
[18:00:35] <andypugh> It would be interesting to see what yoy _do_ get :-)
[18:00:42] <archivist> the form is right but no taper on a spiral hob
[18:01:15] <archivist> there are some tangential hobs
[18:01:18] <andypugh> And I guess that the tooth gap is fixed.
[18:02:20] <andypugh> Have you seen http://www.youtube.com/watch?v=NtKH_fKOod0
[18:02:21] <Tecan> (NtKH_fKOod0) "Bevel gear solutions through up-Gear Technology" by "sandvikcoromant" is "Tech" - Length: 0:06:45
[18:03:09] <andypugh> That looks like quite a stiff machine tool!
[18:04:59] <archivist> andypugh, just had a look in the barber colman book there is a taper tooth method with unsymetrical tooth form, used on anti backlash gear, used an oblique feed
[18:08:50] <andypugh> Sound like fun

[18:17:02] <FinboySlick> That's pretty cool
[18:17:15] <jmasseo> i thought tormach had historically supported mach
[18:17:34] <archivist> yes but they want the lathe to work :)
[18:18:20] <archivist> they need better software for screw cutting

[19:30:56] <andypugh> Mainly steel.
[19:31:12] <cradek> in thin stuff that works (it's forgiving about uprightness)
[19:31:14] <andypugh> But I can't see it working less well in aluminium
[19:31:49] <andypugh> I wouldn't necessarily use it for blind holes.
[19:32:03] <cradek> if your fixture plate has blind holes you're doing it wrong
[19:32:27] <AR__> lul
[19:32:34] <AR__> it will all be through holes
[19:32:36] <AR__> for sure
[19:32:44] <andypugh> Actually, in your situation I think I would become gradually more enthusiastic hole by hole, then get the drill out at about hole number 6
[19:32:57] <AR__> lol
[19:33:08] <cradek> in your situation I'd buy a tapping head and stick it on the drill press

[19:34:06] <false> Hey all, I have a question, earlier I was having trouble tuning my servos. I could not ajust my drives for 0 drift with drives enabled an PID disabled, turns out when I connect a multi meter to measure the output on the VCMD pins I can. I measured the resistance of the drive input and it is about 300ohms. I am using a 7i33, the manual states the load should be at least 5KOhms, could this be
[19:34:06] <false> the problem?
[19:34:49] <AR__> i've heard you can make a holder to lightly hold the tap, with a square hole in the back for the square shank
[19:34:58] <AR__> then run it in a drill press or mill under power
[19:35:07] <AR__> and when you stop feeding it just pulls out of the holder
[19:35:25] <AR__> but if it galls up and sticks it would definitely break
[19:35:43] <AR__> need a slip clutch or something lol
[19:35:54] <JT-Shop> if it galls up your doing it wrong
[19:36:14] <AR__> i mean like
[19:36:20] <JT-Shop> what size tap?
[19:36:22] <AR__> when you hand tap, you break the chip by backing out a bit
[19:36:29] <AR__> under power you dont do that
[19:36:38] <AR__> 1/4-20
[19:36:47] <cradek> you have the wrong tap if you have to back up
[19:36:57] <cradek> get good spiral point taps
[19:36:58] <JT-Shop> nope and I tape thousands of 1/4-20 and never back up except to come out of the hole
[19:37:04] <AR__> hm
[19:37:05] <cradek> even if you're hand tapping get spiral point
[19:37:08] <JT-Shop> yep
[19:37:12] <JT-Shop> yep
[19:37:27] <andypugh> false: Is the 7i33 enabled?

[19:38:31] <false> I was talking to Peter earlier, he gave me some tips I was trying out when I discovered this
[19:38:37] <andypugh> I would expect the multimeter to be a few megs, not enough conductance for the 7i33 to notice.
[19:39:07] <andypugh> With the drive disabled and the mutlimeter on the 7i33 output, can you make a voltage appear?

[19:55:06] <AR__> how in the fuck does that tap work
[19:55:33] <JT-Shop> thread forming tap, not cutting
[19:56:16] <archivist> brute force, moves the metal
[19:56:31] <JT-Shop> I'll have to start buying my taps from enco they are more cost effective
[19:57:16] <Loetmichel> thread forming is great
[19:57:17] <AR__> o
[19:58:07] -!- zzolo has quit [Quit: zzolo]
[19:58:10] <Loetmichel> no swarf, harder and smoother thread surface, much more rigid tap tool (breaks not that easily).
[19:58:43] <Loetmichel> only drawback: taps are expensive and makes a "volcano" on the surface of the material
[19:58:58] <Loetmichel> i.e the holes should be generously countersunk
[19:59:25] <cradek> and best if reamed to size
[19:59:37] <AR__> https://www.youtube.com/watch?v=WRAXB545MVA
[20:00:21] <cradek> I've only form-tapped 4-40, but it worked great (blind holes)
[20:01:21] <Loetmichel> the company which builds our computer cases does it all day
[20:01:29] <Loetmichel> m2,5 to m8
[20:01:36] <Loetmichel> in aluminium and mild steel
[20:01:46] <Loetmichel> best threaded holes ever
[20:02:33] <Loetmichel> especially in zinc plated sheet steel
[20:03:10] <Loetmichel> whre his cnc punch makes little "volcanos" on poupose to sink the form-tap in
[20:03:45] <AR__> lol
[20:03:53] <Loetmichel> (i.e uses a 2,8mm punch and a 4.8mm die to make the pre-holes for the treads
[20:04:12] <archivist> how many holes per tap?
[20:04:24] <Loetmichel> because a m3 thread in 1mm steel doesent hold much
[20:04:36] <Loetmichel> so it has at least 2,5mm of thread
[20:04:45] <Loetmichel> about a 1000 or so
[20:04:52] <Loetmichel> then the tool is worn
[20:05:06] <archivist> lubricated or dry
[20:05:12] <Loetmichel> lubricated

[20:48:44] <andypugh> No. The 7i64 does not talk USB
[20:49:05] <andypugh> Hang on, I am actualy incorrect...
[20:49:37] <andypugh> It would be interesting to try.
[20:50:29] <andypugh> false: What other hardware do you have?

[20:51:15] <andypugh> (Also, what voltage and current do you need to switch? The 7i64 has quite a high voltage and current rating)
[20:51:24] <false> I have a Mesa 5i20 + 2x 7i33 + 1x 7i37ta
[20:51:56] <false> I need to switch some relays for an ATC and some extras like auto lube, coolant, etc
[20:52:53] <false> So the 5i20 is full, and I was thinking to interface via usb
[20:53:04] <andypugh> You have run out of outputs on the 7i37TA?
[20:53:40] <false> Yes almost, so I thought this might be a nice solution for non real time critical stuff
[20:54:16] <andypugh> It ought to be possible, but I don't know if the software components exist
[20:54:49] <false> I couldn't find anything on it so that's why I asked here
[20:55:30] <false> What would we need for this? An rt compatible usb driver (rt-usb maybe??) and a way to interface this to LinuxCNC?
[20:55:37] <andypugh> The 7i33 encoder connections are RS422 and the comms protocol that LinuxCNC supports the 7i64 on is Rs422. It is just about feasible that a special bitfile could allow you to connect the 7i64 to 4 terminals of a 7i33

[20:56:09] <false> Sounds very interesting, I should ask Peter about this right?
[20:56:26] <andypugh> I could try plugging a 7i64 into a USB port and seeing if hal_input can see it...
[20:56:47] <false> I'll try that, how would I go about doing that?
[20:57:08] <FinboySlick> Not that I know what I'm talking about, but if LinuxCNC can drive gpio directly, perhaps there's a usb gpio interface.

[22:55:24] <false> then open another terminal to do you work
[22:57:10] <false> did you enable anonymous logon for the nfs?
[22:57:35] <false> If you do that we can at least determine if this is a permissions problem
[22:59:16] <andypugh> I am not sure what you mean
[22:59:37] <false> you can enable anonymous logon in the nfs share for the nas
[22:59:58] <andypugh> I can?
[23:00:48] <false> If I remember correctly (my brother has one)
[23:02:17] <false> hang on let me look it up
[23:04:03] <false> cant find it, but just thought of something
[23:04:23] <false> on the nas go to /etc/host.allow
[23:04:34] <false> I mean edit
[23:05:03] <andypugh> Aha! http://www.smallnetbuilder.com/nas/nas-reviews/31314-wd-my-book-live-reviewed?showall=&start=1 says that only the default Public mount is NFS-able. (not that we have had any more luck with that)
[23:06:11] <false> correct, but you can add more
[23:06:21] <false> but first you need to get this one working

[23:07:35] <andypugh> "hosts.allow" even
[23:07:39] <false> yes
[23:07:58] <cradek> nfs can be done over tcp or udp, and some servers require the mount request come from a reserved port

[23:08:50] <cradek> I don't recall guessing that

[23:09:41] <false> yep, already tried the -0 nfsvers=3

[23:15:14] <andypugh> How do I tell?

[23:18:29] <andypugh> I am reasonably happy with the NAS
[23:18:40] <false> cradek: that should list the listing ip for portmap right?

[23:19:08] <cradek> on the command line? not necessarily.

[23:22:45] <andypugh> false: Only 00:22 here :-)
[23:23:44] <false> Ah this is starting to get interesting
[23:24:03] <false> but thats not via nfs right?
[23:24:39] <andypugh> The command was sudo mount ./Resources
[23:25:03] <andypugh> If I can figure out how to unmount it I can try again with an explicit -t nfs
[23:25:49] <andypugh> On the NAS everything in default/portmap is commented
[23:26:04] <false> umount
[23:26:44] <false> umount /dir of course
[23:27:04] <false> Never got why they didnt name it unmount
[23:27:45] <andypugh> Yes, -t nfs still mounts nicely in the Mac.
[23:28:59] <false> ok then run the following on the dn2800 box
[23:29:40] <false> sudo apt-get install nfs-common
[23:29:57] <andypugh> Already did that hours ago
[23:30:22] <false> of course you did im sorry ;P
[23:30:30] <andypugh> nfs-common is already the newest version.

[23:48:38] <false> last shot
[23:50:19] <false> mount -t nfs -o timeo=50 nfsvers=3 ip.of.nas/nfs/Public /mnt/mybook
[23:50:43] <false> don't know about the CAPS Public
[23:50:58] <false> use the same url as you did on the mac
[23:52:50] <false> if this doesn't work we can try to force tcp connections only
[23:53:01] <false> and after that I am out of ideas
[23:53:24] <andypugh> That worked
[23:53:30] <andypugh> :-)
[23:53:34] <andypugh> But why?
[23:53:54] <false> the problem lies with the server not responding fast enough, the default timeout for this is 0.7 per command
[23:54:03] <false> now its 5 seconds
[23:54:55] <andypugh> Is that a sticky setting?
[23:54:59] <Tom_itx> the woes of technology
[23:55:08] <andypugh> Because now it works without the -timeo
[23:55:09] <false> no you need to put it in your fstab
[23:55:34] <andypugh> But previously it was taking about a minute to timeout..
[23:56:12] <false> It times out trying to connect, the timeout we set just now is the timeout for the client to wait for a server response after a command
[23:56:58] <false> So if the client ask to connect it waits 0.7 seconds by default, if this doesnt work it tries again for 60 seconds or so
[23:57:31] <false> so if the server doesnt respond within that period the connection is never established
[23:58:17] <false> just put it in your fstab like this
[23:58:53] <andypugh> /home/andypugh/git nfs rw,hard,intr,timeo=50 0 0
[23:58:59] <andypugh> ?
[23:59:15] <false> yes and add nfsvers=3 to be sure
