No worries, that has caught a few.

The torch should end up where it originally started form. Normally you would set you home position around 5mm or so from the top. If you jog down for any reason then you should jog back up before doing anything else.

Hello.
My plasma does not start at the command of m3.
M3 $0 S1 or M3 S1
M3 $0 S1 will probe, go to pierce height, and stoped without error messages and waits for something.
The ENABLE button is lit green.
The plasma starts up by pressing the "PULSE" button. According to the program, no.
More precisely, it started up once, yesterday, and cut a sheet of metal in half. Since then, he does not want to start even on old files. Only on the button in the GUI (Axis).
LINUXCNC - 2.8.2-11-g6a3d0a434
PlasmaC v0.188
plasmac.torch-enable is ON
Fresh config.

Warning: Spoiler!

if hm2_5i25.0.7i77.0.0.output-08 is true (check with halmeter)
and the 7I77 output 08 is not high , this indicates a hardware
issue.

if I press "PULSE" button hm2_5i25.0.7i77.0.0.output-08 is true and plasma starts.
if I run "M3 S1" hm2_5i25.0.7i77.0.0.output-08 is false and plasma wait for something after probing.

I guess you need a PlasmaC expert to tell you what it is waiting for...

The reason for your issue is that the Probe Speed is too slow. What is happening is that it probes down fast, finds the material, moves up a little bit then probes down slow to find the material again. Because the value is too low for the resolution it just stops. 60 is the minimum I could run on your config. If you need to probe any slower than 60 then you could add this line to the connections.hal file:
setp plasmac.resolution 10

A couple of other issues I see are that the axes and joint maximum velocities are not correct. You need to have the axis max_vel double the value of the joint max_vel. The joint max_vel should be the actual maximum velocity that you require.
