Re: [Emc-users] MPG pendant
Le 2014-02-06 19:55, Dewey Garrett a écrit : - Several folks have reported that the pendant stops updating. On mine, if the pendant is idle (no buttons pressed, no wheel movement) for approximately 40 seconds, the display stops updating. Pressing any button restores display updating so I just leave one button unassigned and press it to wake up the pendant. Running the xhc-hb04 program executed standalone as a simulator now reports when it detects the pendant going to sleep; when using with hal, a pin is created for the condition (xhc-hb04.sleeping) I think it would be good to merge to master to get some testing with other pendants. Thanks for the new feature to handle sleeping. I have tested with my 16 buttons MPG, but the behaviour is different: it does not send 04 00 00 00 00 00 when entering sleep mode. However, I get this message sometimes when powering up the MPG.

Le 2014-05-03 04:50, Jon Elson a écrit : There is a pic from the HD5000 webcam in the Wiki at http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Adding_Digital_Zoom_To_Camview-Emc that is not very impressive, you might be able to get it within .1mm but that's about it. I would like to clarify an important fact: the picture from the wiki is taken with a workpiece / camera distance of 100mm. At this distance, I achieved better than 0.05 mm accuracy, but with uncomfortable conditions. I agree, 0.1mm is the practical performance figure at this distance with this setup. Better resolution can be reach when going down to 25 mm distance as demonstrated here http://blog.f1oat.org/2014/05/03/hd5000-edge-finder-test-at-25-mm-distance/ However, I confirm HD5000 is limited because it does not have a microscope lens system. I use digital zoom with all well know drawbacks. My experience is that the main problem with this kind of camera setup (camera mounted on X/Y axis, not on Z) is the vertical alignment for proper operation with any height of the workpiece. That may be the major limitation to the overall accuracy of the system.

Gene,
Are you sure that config was not just for Gmoccaypy or Gscreen?
No I am no sure. The wiki pages does not specify. I have about 5 or
6 camviewcfgs I have collected, none of which give the DRO.
And something else bothers me too. That line
EMBED_TAB_COMMAND = ./camview-emc-f1oat.py -v 1280x720 -c camview.cfg -g
cam.ui -H campins.hal -w {XID}
does not work at all if I use an uppercase -C, which is what every example
of that line I have found shows as uppercase, but I have to use lowercase.
Then, because the pins referenced in campins.hal, have the -C config file as
part of the pinname, if I change the camview.cfg to camviewcfg, then I have
to edit campins.hal to match. But since the float.py version doesn't work,
with a full debug indicating the problem step is:
File /usr/lib/python2.6/subprocess.py, line 633, in __init__
errread, errwrite)
File /usr/lib/python2.6/subprocess.py, line 1139, in _execute_child
raise child_exception
OSError: [Errno 13] Permission denied
which doesn't happen if i use the /usr/bin/camview-emc in place of the
./camview-emc-float.py version.
And now with my screwing around, I've done something to the camera itself,
very poor pix even in cheese, extremely out of focus and posterized. A
walk to the shop to unplug it, count to 5 and plug it back in might be in
order. But at 4AM, the bed is closer since its raining.

Re: [Emc-users] endoscope camera mount?
Le 2013-11-23 19:35, Marcus Bowman a écrit : I have an optical machine scope that has that kind of gimbal adjustment, although it is just two screws which act on a spherical arrangement inside (I think). Works fine. I have also cobbled together an adjustable camera mount for a USB camera, but don't use it (prefer my optical scope). What would be the disadvantage of mounting it permanently on the side of the head? That way it is always there, and you only need to calibrate its position relative to the spindle, once. You could use a work offset. Marcus Your solution sounds like the one I have here: http://blog.f1oat.org/2013/09/01/the-webcam-mounting-bracket-after-machining-work/ The initial vertical alignment of the camera is painful, but when it is done, it is a pleasure to set the zero on the workpiece so quickly. On my setup, the only drawback I have is that the camera Z position is fixed. So, the camera field of view (and the accuracy) depends on workpiece thickness.

Hello Gene, You need to set the offset in the tool table, tool #99. I have used the following procedure : - drill a very small hole with a V-carve tool in your spindle, 0.1mm depth - set X/Y zero on the DRO (this is the reference hole position) - now, move your table to center the camera on the hole - store the DRO X/Y reading in the tool #99 - reload the tool table - move back to X=0 Y=0 (so your spindle is now back on the hole) - now, if you check the G43H99 checkbox, the table should move and the camera should be perfectly centered on the hole and you still read X=0 Y=0 on the DRO - uncheck G43H99, now the spindle should move were the camera was pointing, and should should read again X=0 Y=0 Now, your setup is ok. The procedure to set the zero for a new workpiece is: - check G43H99 - move your table to point your camera to the needed zero - set DRO to 0/0 - uncheck G433H99 - the spindle should now be at the needed zero position Be careful with the nc file associated to G43H99: it does not move the spindle up, so you may experience collision if it is to low. I have modified the nc file to move up to top position before any X/Y motion. Do also need to drill a 2nd hole and similarly record its location, but against the first set of data so as to facilitate the auto correction of any rotation of the workpiece about the Z axis? There is a Z rotation compensation feature in LinuxCNC, but I do not know how to use it. On my side I use the camera to align the workpiece along X axis: I point my camera on a corner of the stock, then move along X and check if the camera center follows the edge. Then adjust the stock if I see deviation, and recheck. The workpiece is aligned in 2 or 3 iterations. Frederic. -- Rapidly troubleshoot problems before they affect your business.

This camera does however seem to be autofocus over about a 1.5 range of vertical motion though, and apparently without any xy movement as it does this. My hardware setup looks different from yours: my machine is a gantry and the camera is not attached to the spindle. = its Z position is fixed. See http://blog.f1oat.org/wp-content/uploads/2013/09/20130831_171726.jpg So, there is no effect on camera if I move the spindle up. Yes, in your case you will need a different strategy for the _camoff.ngc and _camon.ngc files. You can keep the original ngc files and be careful about your spindle height before clicking on G43H99. Reading some of the code, as in camstore.ngc in particular, it appears that IF this is the code executed when the Store XYZ button is clicked, which we can apparently do 4 times after measuring the holes from both sides, it appears that it builds up a record array, 2 by 4, that can then be used to calculate the required corrections. I am thinking this then works with the align buttons on the right to achieve this. Since there aren't any docs for this, I guess its up to us to decipher it, using the code for the documentation. When you click Save XYZ, a new point is stored in the memory. Up to 4 points can be stored. When you click Center3 or Center4, your table will move automagically to the center of the circle you have pointed with 3 or 4 points. 3 points centering is ok if you do not have two points aligned on same X or Y line 4 points centering is more convenient because typically you will point and jog only on X or Y to get the opposite point.

Re: [Emc-users] Servo and Mesa pulse encoder/velocity feedback
This Fanuc drive will be in runaway condition if it does not receive a velocity feedback. It has an internal analog closed loop to track the velocity command and control the motor rpm. This is why we absolutely need to derive this feedback from the quadrature encoder somewhere. Frederic.

About original Fanuc F/V converter delay comparing to mesa, unfortunately we cannot measure because it is faulty. Another clue: we have very similar oscillations at low or high speed.

[Emc-users] Fanuc analog drive & LinuxCNC tuning
Hello At Electrolab hackerspace, we are working on the retrofit of a Mori-Seiki SL0 CNC lathe. We are are using a Mesa 6i24/7i48 combination. The drive is a A06B-6047-H208 (double velocity control unit). Axis motors are A06B-0641-B011 and A06B-0642-B011 (yellow cap). The position feedback comes from a 2000ppr encoder. We use the Mesa board to convert the pulses to an analog feedback velocity signal. We have done the HAL cabling as below. First results are promising : we can control the position. But we see some oscillations on the velocity (periodic with 33 ms period). Oscillations start when the position command changes, and never stop, even when the pos-cmd becomes constant. Same issue if we disable the PID loop in HAL. So we believe the problem is coming from the drive. When we decrease the analog gain in the drive after the error amplifier (comparison between velocity command and feedback), we can decrease the oscillation. As we can see a phase compensation circuit in the drive, we assume this is to compensate for delay on velocity feedback. So, we have tried to add some delay on the velocity feedback assuming original F/V converter from the Fanuc control board may be slower than what we have with Mesa. Not much success: that changes a little the oscillation period, but we cannot cancel oscillation. Anyone knows how we can tune the drive (unfortunately we have not the documentation for this part number) ?

Re: [Emc-users] MachineKit on the BeagleBone Black
As far as I know, PRU micro-code is using sampling for counting. I have validate up to 100 kHz, with a PRU period of 2.5uS. So you have 4 samples per pulse period, which is enough, but not fully satisfying if you need to master the jitter. See http://blog.f1oat.org/2016/04/10/adding-velocity-estimation-in-hal_pru_generic-encoder/ The fix I have done on MK code is for frequency measurement. I am using PRU based encoder for MPG, so without strong constraints. 6000 rpm is exactly the upper limit I have with my ECMO-120P lathe. With my 1024 ppr spindle encoder, the pulse rate is above 100 kHz. Possible with PRU, but close to the limit in regards to the overall performance. I do not know if PRU micro-code can sustain 2.5uS period when increasing the number of encoders/pwms it is processing. This is why I am using BBB eQEP instead of PRU for spindle. I do not have specs in mind, but I guess eQEP is capable of more than 1 MHz, as soon as the lowpass filter of the input is well designed.

"You can implement slow user-interface style encoder inputs on the ARM in the servo thread (1 mS period) using the software encoder input and GPIO pins. The PRU encoders will run at the PRU period (10 uS by default) and must use direct PRU input pins. The hardware encoders obviously need to use the specific pins for the channel(s) used.

The generic PRU code built by Charles Steinkuehler can provide this, if the hal command line asks it to do so. Once you have a spindle encoder, you can do lathe threading operation.

Same behavior with machinekit. This is one of the motivations I have for adding physical jog wheels on my machines. Basically, I think the issue is coming from the way the continuous jog is implemented. For example, in gmoccapy code, we can see def on_btn_jog_pressed(self, widget, data=None): ... self.command.jog(linuxcnc.JOG_CONTINUOUS, joint_axis_number, direction * velocity) and def on_btn_jog_released(self, widget, data=None): ... self.command.jog(linuxcnc.JOG_STOP, joint_axis_number) So, for any reason, if you have latency in the execution of on_btn_jog_released(), or in the transmission of the linuxcnc.JOG_STOP, the motion will not stop immediately when you are releasing the key/widget. And more nasty, if the event is lost, the motion will continue until you press/release again the widget, or press ESTOP. On my router, I am using a wireless HB04 pendant. Sometimes, I am experiencing small latency. But with no bad consequences because basically the jog wheel is sending a bunch of incremental commands. So, if you have latency, the motion will stop, and will never move more than the absolute counter value which is transmitted by the pendant. When using a physical button connected to a HAL pin, thanks to hard realtime properties of HAL and polling implementation of digital inputs, this issue does not exist. We could imagine a similar polling mode implementation for widgets so that the motion will stop if polling result is lost or is coming too late from a end2end point of view (over NML or ZeroMQ path).

Re: [Emc-users] Anyone interested in QtQuickVcp support for LinuxCNC? (still the same)
Integrating QtQuickVcp with LinuxCNC should be very interesting. I have developed a DRO component for QtQuickVcp with the look and feel of Gmoccapy. See my CNC mill project: https://youtu.be/LnJv07yeGt0?t=3m28s I am using also Gmoccapy for other machines, and would love having one ported to QtQuickVcp. Many benefits such as running the GUI on a separate tablet as a cheap touchscreen solution. Frederic. http://cnc.f1oat.org On 2017-11-27 16:37, Alexander Rössler wrote: Nicklas Karlsson writes: Yes. I do not like python and guess C++ execute faster so why not. From a developers perspective VCPs where completely outdated and not even close to what modern UI toolkits offer. No developer really want's to work with tk, we can argue about Gtk2. I worked with glade and it works rather well although some of widgets are a little bit limited. Yeah, widgets technology is great for small desktop UIs. However, I also seen big UIs where glade in general is bit of a pain. The more modern Gtk3 UIs also HTML/JS I have heard. QtQuickVcp comes with 2 reference UIs: - Cetus: designed as axis replacement: https://github.com/qtquickvcp/Cetus Look the same as now so I guess it should work great. To simplify remote deployment of the UIs one can simply download and run the "MachinekitClient" (yes, it's Machinekit only right now) and connect to the machine instance. This way, it's extremely simple to circumvent the limitations of embedded computers with weak graphics performance. Use a cheap 100$ tablet as your display and you are fine (https://www.youtube.com/watch?v=LnJv07yeGt0) The way I am heading. To support LinuxCNC would be quite simple. The machine/server part is based on Machinetalk - an open source middleware. Linuxcnc use NML and I think the server part is in working order but have not had enough time to figure out how it is with the "axis" user interface, got more hardware today. Basically, it would be a matter of "adapting" mkwrapper, mklauncher and configserver (Python applications) over to LinuxCNC. ? These are the names of the "server" applications in Machinekit. To make it simple: It would be possible to add the Machinetalk support as a separate package. No need to modify the LinuxCNC source code. HAL Remote - which is useful for custom extensions would require more effort, since it depends on the haltalk server - which goes deep into Machinekit. haltalk, this is between which parrts. Very well described here: https://machinekoder.com/machinetalk-explained-part-4-hal-remote/ From the user perspective, I think the split between LinuxCNC and Machinekit makes absolutely not sense and is very confusing. To make it simple: Machinekit is focused on Non-CNC and LinxuCNC on CNC. -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Additionally, some of those RS-422 transceivers have integrated ESD protection for long wires. You may consider adding a termination resistor to have the transmission line working in good conditions. I think you can check that with a scope on the transmission line: you should see a good square shape, with not overshoot.

[Emc-users] motion.spindle-at-speed and M5 state
Just broke an endmill with a bad GCODE macro where M3 command was missing. I have motion.spindle-at-speed properly tight to my VFD component. But motion does not check it when the spindle is in stop condition. Any clue for inhibiting G1 when the spindle is not activated ? Thanks.

Re: [Emc-users] motion.spindle-at-speed and M5 state
Interlock with motion.motion-type?
To all, thank you so much for your help.
I have solved the issue with a logic based on motion-type + at-speed
driving motion.feed-hold.
Added an override pin linked to a gladevcp button allowing stopped
spindle when using a drag knife.
Here is my HAL component:
component spindle_security "Block non G0 motions when the spindle is not
running";
author "Frederic RIBLE";
pin in s32 motion_type;
pin in bit at_speed;
pin in bit override;
pin out bit feed_hold;
variable double old;
function _;
license "GPL"; // indicates GPL v2 or later
;;
FUNCTION(_) {
if (override) {
feed_hold = 0;
return;
}
switch (motion_type) {
case 0: //Idle (no motion)
case 1: //Traverse
case 4: //Tool change
case 5: //Probing
case 6: //Rotary axis indexing
feed_hold = 0;
break;
case 2: //Linear feed
case 3: //Arc feed
feed_hold = !at_speed;
break;
}
}
And associated HAL configuration:
loadrt spindle_security
addf spindle-security.0 servo-thread
net spindle-at-speed => spindle-security.0.at-speed
net feed-hold spindle-security.0.feed-hold => motion.feed-hold
net motion-type motion.motion-type => spindle-security.0.motion-type
net spindle-security-override spindle-security.0.override

Re: [Emc-users] motion.spindle-at-speed and M5 state
That might be expected behaviour, I suppose. yes, as stated in the manpage. You could try linking to feed-hold? Just tried: that is affecting G0 as well. So not ok for my config because I need G0 motion with spindle stopped. ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] motion.spindle-at-speed and M5 state
Unfortunately this solution is not solving the issue. The motion HAL component seems ignoring spindle-at-speed when in M5 state.

Configure for immediate homing (ie zero HOME_SEARCH_VELOCITY) and then handle to motion interlock with the motion pins. @all, thank you for your help. We prefer using servo drive built-in homing because it is already managing everything, including limit switches. This "external" homing is now working as suggested by Andy, thanks to a small ladder logic. We have modified gmoccapy to trig ladder, instead of calling self.command.home(). At the end of cycle, we are triggering halui.joint.N.home so that LCNC knows homing is done.

[Emc-users] "External" homing
Hello, I have an ESTUN Ethercat servo drive with integrated homing sequence management. Basically, I only need to write 2 registers to start a homing sequence, and then wait for a specific status bit to become true in a status register. Probably easy to map to some HAL pins with a small sequencer written in ClassisLadder opr Python. However, I cannot find good reference about clean integration with LinuxCNC own homing logic. Especially re-using standard GUI homing button/status, and auto-mode inhibition when homing is not done. Any clue? Thanks.
