Qtplasmac without probe

Hello

the qtplasmac interface can be used with 2 spindles (plasma, scribe)
but although scribe doesn’t require a probing sequence, just commanding the plasma “m3” command will initiate a probe sequence and will require a z axis.

i have a need for a double head system without Z axis, where a probe is not present. One of the tools can be linked to the scribe, so it won’t require probing, but the other I need to link to plasma; and remove the probing sequence somehow.

how is this doable? Can I change the m3 macro in its source files? How are they accessible for a simple install?

I know I can use other interfaces such as gmocappy but qtplasmac has conversational and statistics which is great.


edit: 1 approach would be to actually keep the probe and use the negative direction pin on Z axis to drive a timer which drives the ohmic sense signal. But this feels weird.

In master branch there is a pin named plasmac.tube-cut which if set active will inhibit probing. It is an in-progress experiment for some guys setting up a tube cutting machine but may well work for what you want.

If you are using buildbot2 in your sources list then change 2.9-uspace to master-uspace
buildbot2.highlab.com/

If you are using the original buildbot with Debian Buster then change 2.9-rtpreempt to master-rtpreempt
buildbot2.highlab.com/
