Re: [Emc-users] Knee mill conversion - Z axis questions
IMHO if you motorise the knee instead of the quill, you lose all the benefits of the knee elevation for adjusting to workpieces and manually touching off the Z tool, in favour of a very slow and potentially troublesome Z axis which requires all movements to be inverted in a somewhat counter-intuitive way. I agree that whilst possible, motorising the rack and pinion would result in so much slop that it would be next to unusable What is commonly done with manual mill conversions of the turret knee mills is to motorise the quill and leave the knee as manual. The quill is disconnected from the rack and pinion arrangement and large plate clamp is attached to the bottom of the quill This is driven up and down through a ballscrew from a box mounted on the side of the head. The travel is typically quite short (70 - 150 mm), because all major adjustments are done on the knee and quill travel is just used to cut to depth with the standoff between cuts that is required. (same as it was when a manual mill) I have such a mill and it works very well. regards -- Managing the Performance of Cloud-Based Applications Take advantage of what the Cloud has to offer - Avoid Common Pitfalls.

Re: [Emc-users] Knee mill conversion - Z axis questions
If the knee is motorized and has position feedback you could adjust the knee position according to the tool length offset. The slow motion of the knee would not affect the cutting as it would happen only once per tool change. It would be an intuitive action also as the tool gets longer the table gets lower.

[Emc-users] Index (Encoder) Homing
Has anyone setup encoder index homing recently with the Hostmot2 driver? I'm using a 7i43-2 board with a 7i33 and it cannot find the index pulse during the final phase of the homing process. The search velocity is negative and the latch velocity is positive. I've read the manual, the man 9 hostmot2 file etc. Nothing is popping up as being incorrect. HOME_USE_INDEX = YES is present in the INI file. However the axis just keep moving slowly looking for the index pulse but it never sees it. The machine homes fine if HOME_USE_INDEX = NO is present in the INI file. It appears that the encoder index signal is present at the 7i33 board terminal.

Thanks, Dave First is the encoder N index_enable netted to axis.N.index_enable ? if thats correct the index hardware needs to be checked: An easy way to test the index hardware is unlink the encoders index_enable pin in hal and then manually set index_enable. Then rotate the shaft/encoder slowly. The index_enable pin should get cleared at only one shaft position. If it gets cleared immediately, the index polarity may be reversed. if it does not get cleared in one rotation it probably means the index signal is not getting to the FPGA, This can be checked with halmeter or halscope watching the GPIO pin that is used for the index signal. -- Managing the Performance of Cloud-Based Applications Take advantage of what the Cloud has to offer - Avoid Common Pitfalls.

Re: [Emc-users] Gantry Best Practices
On Feb 19, 2014, at 12:42 AM, Charles Steinkuehler char...@steinkuehler.net wrote: If I'm following things correctly, you're doing something very similar to the HAL gantry component I just created: applying the same commanded position to each gantry joint, providing for an offset between the individual joints to avoid racking. Yes, the offset is applied during the homing sequence and was calculated using a large square drawn on the table. Homing is substantially different, but then I don't have fancy Granite drives that will home themselves, so I had to work with LinuxCNC. :) Yes, the Granites cost their weight in gold ;-) but they are very nice drives!! We have large door stops fastened to the ends of the rails and the granites reduce torque, move until they hit these, press against them until a (very low) configured ferror is reached and declare this home. The gantry then moves out to the index pulse on each encoder and then the configured offset it applied to one side. It is very repeatable. Well, first Mesa has to make a BBB cape! Although there are beginning to be some FPGA add-ons for the BeagleBone that might be able to run the hm2 firmware. I'm waiting on my LogiBone kick-starter and there are a few other designs in the works I'm aware of.

I'm using a 7i43-2 board with a 7i33 and it cannot find the index pulse during the final phase of the homing process. The search velocity is negative and the latch velocity is positive. I've read the manual, the man 9 hostmot2 file etc. Nothing is popping up as being incorrect. HOME_USE_INDEX = YES is present in the INI file. However the axis just keep moving slowly looking for the index pulse but it never sees it. The machine homes fine if HOME_USE_INDEX = NO is present in the INI file. It appears that the encoder index signal is present at the 7i33 board terminal. Thanks, Dave First is the encoder N index_enable netted to axis.N.index_enable ? if thats correct the index hardware needs to be checked: An easy way to test the index hardware is unlink the encoders index_enable pin in hal and then manually set index_enable. Then rotate the shaft/encoder slowly. The index_enable pin should get cleared at only one shaft position. If it gets cleared immediately, the index polarity may be reversed. if it does not get cleared in one rotation it probably means the index signal is not getting to the FPGA, This can be checked with halmeter or halscope watching the GPIO pin that is used for the index signal.

Re: [Emc-users] Knee mill conversion - Z axis questions
On Thursday 20 February 2014 09:14:28 Schooner did opine: IMHO if you motorise the knee instead of the quill, you lose all the benefits of the knee elevation for adjusting to workpieces and manually touching off the Z tool, in favour of a very slow and potentially troublesome Z axis which requires all movements to be inverted in a somewhat counter-intuitive way. I'll submit that if you are so limited, its poorly done. Most knees have a range that is entirely usable, and as far as non-intuitive motions go, a sign change in the scaling fixes that with no fuss because its never changed back. So other than the rather large increase in mass to be moved, it should be no different than moving the head up and down a square post, just needing a suitable motor and some of those nitrogen struts to help support the weight, which on a 10x57 mill would be several hundred pounds. A 1 ball screw should be able to do that if enough lift from struts s available. I have looked at a couple of the bigger bridgeport style mills with an eye to doing that, 50+ yo, worn to where I could have had one for a kilobuck, but haven't found my round tuit, and likely won't, my back is going to get fixed, if it can be, before I do much with any bigger machinery. I agree that whilst possible, motorising the rack and pinion would result in so much slop that it would be next to unusable Agreed. What is commonly done with manual mill conversions of the turret knee mills is to motorise the quill and leave the knee as manual. The quill is disconnected from the rack and pinion arrangement and large plate clamp is attached to the bottom of the quill This is driven up and down through a ballscrew from a box mounted on the side of the head. The travel is typically quite short (70 - 150 mm), because all major adjustments are done on the knee and quill travel is just used to cut to depth with the standoff between cuts that is required. (same as it was when a manual mill) That limitation would exasperate me. Sure, what I have is a toy, but in terms of operating envelope nothing made today can match what you get from the larger square post machines. Even my toy has a vertical motion of 14, and can reach it at 30 ipm. Its so flimsy all thats good for is tool changing clearance, or wood carving (I've carved a BP gunstock on it, gets ohh's and ahh's at the range) but I can mount a vice that raises the work 3+ inches without a problem that ball screws in the xy wouldn't fix 90% of. Thats a WIP. http://www.grizzly.com/products/Heavy-Duty-Benchtop-Mill-Drill-with- Variable-Speed-and-Power-Feed/G0762 Gives you a machine with an operating envelope of 18h x 7.5y x 22x, or 1.71875 cubic feet. For 2774 USD sitting on your 1/2 ton rated table, or another $275 on their stand. Add 3 ball screws suitable motors mount hdwe and LCNC. Might be $4500-5000. And that is a much larger cubic volume than you can get in any Bridgeport style machine when limited to driving the quill. I have such a mill and it works very well. regards -- Managing the Performance of Cloud-Based Applications Take advantage of what the Cloud has to offer - Avoid Common Pitfalls.

Ok i am not well enough conversed to explain this in detail,but i will try. Having recently been involved with the beaglebone/machinekit setup,i accidently came across a problem. I found that speradically the motors would make a noise like frying an egg after movement had finished. This after some investigation by Charles,Jeff pollard,and few others,was found to be the dir line hunting after a movement. This has turned out to be a known problem with the pru and the fact it is using position feedback and not velocity feedback. So the outcome after a few discussions was that the hal file needs changing to utilise the stepgen in velocity mode. Now i am at a complete loss how to do this,so is there anyone out there that can help? Charles is snowed under at the moment otherwise i am sure he would oblige. I will try attatching my hal file. I am sure there are others that will explain this better than me because of my limited knowledge. # These buffer ALL siginal used on the DB25 port # The board also has a pair of a set of four 0805 size jumper resistors # these can be used to output either the standard Spindle/Mist/flood and # input ALIM from the DB25 pins # or allow BBB SPI singals to be routed to the DB25 connector instead. # The ALIM RC buffer Capacitor would need to change if this # option was used.

Hi Chris - Here's part of the code - it's obvious early on without all
of it. I'll post the config tomorrow - machine is at work.
BTW - Changing N190 to
N190 G64 P0.5
and it runs better, but that's far too much deviation.

I'm using a 7i43-2 board with a 7i33 and it cannot find the index pulse during the final phase of the homing process. The search velocity is negative and the latch velocity is positive. I've read the manual, the man 9 hostmot2 file etc. Nothing is popping up as being incorrect. HOME_USE_INDEX = YES is present in the INI file. However the axis just keep moving slowly looking for the index pulse but it never sees it. The machine homes fine if HOME_USE_INDEX = NO is present in the INI file. It appears that the encoder index signal is present at the 7i33 board terminal. Thanks, Dave First is the encoder N index_enable netted to axis.N.index_enable ? if thats correct the index hardware needs to be checked: An easy way to test the index hardware is unlink the encoders index_enable pin in hal and then manually set index_enable. Then rotate the shaft/encoder slowly. The index_enable pin should get cleared at only one shaft position. If it gets cleared immediately, the index polarity may be reversed. if it does not get cleared in one rotation it probably means the index signal is not getting to the FPGA, This can be checked with halmeter or halscope watching the GPIO pin that is used for the index signal. Hi Peter, No it was not. Let me try that. Thanks! Dave It works!

I'm a bit too busy to fiddle with the HAL code for a week or so, and was hoping someone might be able to help Mark get his HAL file sorted out: Quote from Peter: The current position mode driver code makes sense for a software implementation but suffers from some issues when used with a hardware stepgen (and since the PRU stepgen is a asynchronous (to servo thread) DDS it probably has the same issues) To do this you set the stepgen in velocity mode, and set a P of around 50 and a FF1 of 1.000. The nice thing about this is you can now use the PID comps facilites to fix a number of deficiencies in the built in position mode code: 1. Setting the PID comps maxerror to some small value makes the stepgen avoid large corrections based on the servo thread jitter in sampling the stepgens position (effectively slew limiting the corrections) this make sense for hardware or PRU based system where the stepgen DDS is a better timing reference to short term timing than the servo thread. 2. Setting the PID comps dead zone stops the toggling 3. A tiny bit of FF2 can be used to compensate for the delay between sampling the stepgen position and writing the new DDS rate In my testing, if you have any significant servo thread jitter, using a servo type config like this results in much better stepgen performance the the built in position mode controller freeby.mesanet.com/7i76e.zip has an example servo mode stepgen setup -- Charles Steinkuehler char...@steinkuehler.net signature.asc Description: OpenPGP digital signature -- Managing the Performance of Cloud-Based Applications Take advantage of what the Cloud has to offer - Avoid Common Pitfalls.

Re: [Emc-users] Crackling motors using Beaglebone
Mark, when this happens, have you tried unplugging the step and dir(everything but enable) from the beaglebone to verify that it isn't just coming from microstepping on the driver itself? I know I've experienced similar crackling sounds on some stepper drivers that was completely isolated from input from step/dir source.

Re: [Emc-users] Crackling motors using Beaglebone
Hi, I looked at the DIR line on a bare beagle bone with no attachments. The DIR line can end up toggling after a move has stopped. But it does not *always* end up toggling after a move. Pressing the power button in AXIS clears the situation until a future move. The STEP line does remain inactive, so there is no unwanted movement. Mark is using Geckos which are optically isolated, so the chance of electrical noise contributing to the problem is unlikely. I've also noticed the problem with the Allegro A3977 drive chips. I'm not sure why either the Geckos or the A3977 would care about a toggling DIR line while STEP is inactive, but they do. Perhaps it is some kind of noise issue within the drive itself (i.e. not electrical in the wiring/grounding sense). In any case, the solution (when found) will be to stop the line from toggling at all. Hopefully Peter's suggestion of a different HAL configuration will work.

Re: [Emc-users] Crackling motors using Beaglebone
Peter's solution will work. I was going to add a dead-band to the PID control internal to the HAL component that talks to the PRU, but Peter's suggestion of pushing the PID outside the PRU driver and into HAL makes a lot more sense. The existing HAL PID component is vastly more sophisticated than the PID inside the PRU driver, and pushing it out into HAL not only makes the configuration more unix and LinuxCNC like, but doesn't require any new code to implement. I just don't have time to play with HAL right now (I'm getting ready for a 100K run this weekend), and my test machine is currently in various pieces so I couldn't check things out even if I had time to make the change. I can probably get to it next week sometime, but I'm hoping someone will beat me to it. On 2/20/2014 11:19 AM, Jeff wrote: Hi, I looked at the DIR line on a bare beagle bone with no attachments.

Re: [Emc-users] Knee mill conversion - Z axis questions
On 2/20/2014 2:07 AM, Schooner wrote: What is commonly done with manual mill conversions of the turret knee mills is to motorise the quill and leave the knee as manual. The quill is disconnected from the rack and pinion arrangement and large plate clamp is attached to the bottom of the quill If the quill doesn't project below the head casting when all the way up, and there's no slot like on Bridgeports and clones to attach a ballscrew nut to, there's still a way to add CNC control. Replace the spindle retainer nut with a custom made plate that has a projection down and out to one side to connect the drive. To have the thread rotated correctly in relation to the drive attachment isn't difficult. Make the new nut/plate oversize and screw it into the quill, then mark where the drive attachment will mount, cut away the rest of the excess material. An alternate way would be to make the nut thicker so that a clamp style mount can be used, like how DRO mounts are often fitted to drill presses and drill/mills. -- Managing the Performance of Cloud-Based Applications Take advantage of what the Cloud has to offer - Avoid Common Pitfalls.

[Emc-users] ngcgui support for gcmc
ngcgui (and pyngcgui) now support Bertho Stultien's Gcode-meta-compiler (gcmc) in git master and in recent buildbot debs. Ngcgui creates entry boxes to simplify testing and use of: a) single-subroutines gcode files (.ngc) b) gcode meta compiler files (.gcmc) Notes: 1) gcmc (version =1.4.3) must be installed independently and located as an executable file in the user PATH, see: http://www.vagrearg.org/content/gcmc 2) linuxcnc can be built for run-in-place (RIP)) from git master or installed from a recent buildbot deb (19Feb2014 or later), instructions at: http://buildbot.linuxcnc.org 3) Example ini files for demonstration are located: configs/sim/axis/ngcgui/ngcgui_gcmc.ini configs/sim/axis/ngcgui/pyngcgui_gcmc.ini configs/sim/gscreen/ngcgui/pyngcgui_gscreen_gcmc.ini configs/sim/touchy/ngcgui/pyngcgui_touchy_gcmc.ini 4) The examples use .gcmc files located in: nc_files/gcmc_lib nc_files/gcmc_lib/square.gcmc nc_files/gcmc_lib/drill.gcmc nc_files/gcmc_lib/star.gcmc (Bertho Stultiens) nc_files/gcmc_lib/wheels.gcmc (Alan Battersby) 5) To modify the examples or create new .gcmc files: a) create your own directory, for example: $ mkdir ~/linuxcnc/myfiles b) copy or edit your own .gcmc files, example for a deb install: $ cp /usr/share/linuxcnc/ncfiles/gcmc_lib/square.gcmc ~/linuxcnc/myfiles/mysquare.gcmc c) add your directory to the subroutine path defined in the ini file. Example: [RS274NGC] SUBROUTINE_PATH=~/linuxcnc/myfiles:../../nc_files/ngcgui_lib:../../nc_files/gcmc_lib:../../nc_files/ngcgui_lib/utilitysubs (above is all on one line,directory names are separated by colons (:)) Note: Linuxcnc searches for a subroutine file by name following the [RS274NGC]SUBROUTINE_PATH. The first file found with a matching name is used. d) add your files to the ini file in the [DISPLAY] stanza, example: [DISPLAY] ... TKPKG = Ngcgui1.0 NGCGUI_FONT = Helvetica -12 normal NGCGUI_PREAMBLE = in_std.ngc NGCGUI_SUBFILE= square.gcmc NGCGUI_SUBFILE= mysquare.gcmc # specify for a custom tab page NGCGUI_SUBFILE= ... (including a custom tab page allows you to search for .ngc and .gcmc files as long as they are in the SUBROUINE_PATH) 6) After creating your own .gcmc file, add tags within the file to identify variables requiring entry boxes. For example, to tag a variable named frate, include the line: //ngcgui: frate = 100; To specify a default value and label, use: //ngcgui: frate = 100; //, Feed Rate (See the included demo .gcmc files for more examples.) 7) When a .gcmc file is selected, ngcgui submits it to the gcmc compiler, and places the resulting gcode file in the [DISPLAY]PROGRAM_PREFIX directory for use by Linuxcnc. 8) Ngcgui can combine .gcmc and .ngc files from multiple tab pages Additional Referencess: http://www.linuxcnc.org/docs/devel/html/gui/ngcgui.html http://www.linuxcnc.org/docs/devel/html/config/ini_config.html#_rs274ngc_section_a_id_sub_rs274ngc_section_a http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=commitdiff;h=7bdd488c0da77cfe6014fb3cd177b538cb3e67fe -- Dewey Garrett -- Managing the Performance of Cloud-Based Applications Take advantage of what the Cloud has to offer - Avoid Common Pitfalls.

[Emc-users] Canned cycle relative motion weirdness
Hi, I've been looking into the canned cycles in LinuxCNC and the relative version is odd. The gcode documentation has an example: G0 X1 Y2 Z3 G91 G98 G81 X4 Y5 Z-0.6 R1.8 L3 It should make a nice pattern, but it drills in the wrong direction (down-to-up). The R-word need to be -1.8 (negative) to make it drill in the right direction. However, the documentation states a sequence of rapids/moves and indicates the positions which I cannot reproduce. F.ex. I cannot create a parameter combination that would move to the noted Z positions. Am I missing something or is there bitrot in either the documentation or interpreter? -- Greetings Bertho (disclaimers are disclaimed) -- Managing the Performance of Cloud-Based Applications Take advantage of what the Cloud has to offer - Avoid Common Pitfalls.

[Emc-users] John Thornton - Mill GCode Generator metric small issue
John; I do everything in metric; the Preferences-Preamble, when I change G20 to G21, and save, it does not seem to have saved next time I run the program. Still trying to run through this program, but thank you for your efforts - I think the effort is worth it.

I was going to add a dead-band to the PID control internal to the HAL component that talks to the PRU, but Peter's suggestion of pushing the PID outside the PRU driver and into HAL makes a lot more sense. I might mention that I have to use deadband with the Pico universal stepper controller, as it uses the traditional PID and the step generator is velocity only. This allows the board to be used with either open- or closed-loop stepper setups with minimal change.
