PNCconfig error

Category: General LinuxCNC Questions

I have encountered this error after restarting a configuration in PNCconfig. I have attached a screen shot. 
Please advise on how to proceed.

Regards

Time to revisit coolant mapping of M-codes in Linuxcnc

Category: General LinuxCNC Questions

are you at liberty to share those mappings ? 

They're just basic xxx.ngc subroutine files, specified in the INI file. Not an actual remap of an existing M-code with new behavior and -P/-Q passthrough params.
[RS274NGC]
PARAMETER_FILE = lathe.var
USER_M_PATH = /home/lathe/linuxcnc/configs/LATHE_REV1.53/MCODES/
SUBROUTINE_PATH = /home/lathe/linuxcnc/configs/LATHE_REV1.53/subroutines
RS274NGC_STARTUP_CODE = F10 S0 G7 G18 G20 G40 G49 G54 G64 P0.001 G80 G90 G91.1 G92.1 G94 G97 G98
;ORIENT_OFFSET =
#REMAP=G12.1 ngc=g121
#REMAP=G13.1 ngc=g131
REMAP=M200  modalgroup=10   ngc=m200
REMAP=M201  modalgroup=10   ngc=m201
REMAP=M202  modalgroup=10   ngc=m202
REMAP=M203  modalgroup=10   ngc=m203
REMAP=M210  modalgroup=10   ngc=m210
REMAP=M211  modalgroup=10   ngc=m211
REMAP=M212  modalgroup=10   ngc=m212
REMAP=M213  modalgroup=10   ngc=m213
REMAP=M220  modalgroup=10   ngc=m220
REMAP=M221  modalgroup=10   ngc=m221
REMAP=M222  modalgroup=10   ngc=m222
REMAP=M223  modalgroup=10   ngc=m223
REMAP=M268  modalgroup=10   ngc=m268
REMAP=M269  modalgroup=10   ngc=m269

M210 to M213 are my extra mist valves.  Subroutines look like this:
o<m210> sub

;MIST 2 ON

;MIST2 VALVE             motion.digital-out-00
;MIST3 VALVE             motion.digital-out-01

M64 P0                                  ;TURN ON MIST2 VALVE

o<m210> endsub [1]
M2

The other ones are main and sub drawbars, and 268/269 are G10 front/back tool rotations (hoping to incorporate that in post processor so the display automatically flips to the right orientation).

I could have mapped them to a more logical M-code number... Maybe I'll see if m207.1.ngc & m207.2.ngc work and not cause LCNC to vomit.

Parse Error

Thanks for you time Phill The tool numbers were generated by the sequence they were created in SheetCam. As it sits now it is usable for me to do work. As I assume the bit size and positions (inside, out side, and one the line) should be kept correct by SheetCam and EstlCam. This should keep the dimensional size correct for my projects.
your statement

This is all using the axis_mm sim config.
does that mean I need to use metric measurements or is there an inch version??

linuxcnc-dev is missing?

Category: Installing LinuxCNC

Couple of months ago I installed Linuxcnc rip on an intel i5 4the generation it installed flowlesslly. Try not to skip any steps, take your time don't rush otherwise you will have start all over again.
[edit] OOPS just realized that you loaded linuxcnc. You must start with Debian 12 os only nothing else.

This is all using the axis_mm sim config.
Downloaded your zip file 4washersLinuxcnc.zip and extracted the contents.
Created a tool #23.
Loaded 4washersLinuxcnc.tap which gave a parse_file interp_error.
Duplicated 4washersLinuxcnc.tap and renamed it 4washersLinuxcnc.ngc
Loaded 4washersLinuxcnc.ngc which gave a parse_file interp_error.
Created several tools, #9, #10, #19, #20.
Changing tool numbers in the files and then loading the files showed that tool numbers greater than #9 always gave a parse error and tools #9 and below mostly loaded without error.
I did see that your file had dos style line endings so I changed that to unix style and it made no difference to the above.

The above makes no sense to me and is all I have time for at the moment.

I checked every STEP-/STEP+ and DIR+/DIR- pair, there was no meaningful potential between any of them. I only checked STEP0- and DIR0- relative to GND and no meaningful change when jogging. I guess that means both are shot.

Replacing those two chips should not be too hard. I don't like that I don't know what caused the failure, I guess maybe some chip shorted it, since I have not messed with the electrical system in a while. I don't know how that would damage both chips, though.

Also, what are the overheating signs on U7? Is it that blob covering the 5?
