Manual tool change + tool lengh touch off

The problem might be the hyphen in the name. (Just a guess). Try it without that. The way that filenames get passed through the G-Code interpreter is a bit messy, they get changed to all lower-case and spaces get removed, the same might be true for "operators".

I thought I tried this at first, but so it worked.

The hyphen is not the reason, I've already tried it without and the fred.ngc has none either.

It seems to work if i call o<first-tool> call in a *.ngc file, but I can't run it from the MDI console. But this should be enough for the postprocessor.

Which EMC2 version are you running?

I vaguely recall an improvement in the way it searched for subroutines, but that was rather a long time ago.

I just did a test:

In the ini file I have PROGRAM_PREFIX = /home/andypugh/emc/nc_files

In the nc_files directory I have:
test1.ngc
test.ngc

test1.ngc contains: test.ngc contains: And it all "just works" with version 2.3.5

Incidentally, the dev list was busy last night sorting out an issue with probing in subroutines. I think it is only a problem when the subroutine is called from MDI_COMMAND, but I have asked for clarification. The issue is one of returning before the end of the probe, I think, so not related to your general subroutine problem.

You could use something similar to my touchoff file that I use on my plasma torch.

move to start point of the cut...
o<touchoff> call [0.080] [0.02] [0.06] (Touchoff and start torch)
...


my touchoff.ngc file:

o<touchoff> sub
(#1 pierce height, #2 pierce delay, #3 cut height)
F10
G38.2 Z-1.75 (Probe to find the surface)
G91
G1 Z0.070 (Raise up to Z0)
G90
G92 Z0 (Set Z0)
G1 Z#1
M3 S1
M66 P0 L1 Q5 (Wait for Arc OK from Torch)
G4 P#2 (Pause for pierce delay)
F25
Z#3 (goto cut height)
o<touchoff> endsub
M2

Ah, yes. I didn't realise that you were calling it from MDI. I just tried it in version 2.4.3 and it worked fine. Perhaps you are using 2.3?
