Plasmac migration problems

I've spent a little bit of time trying to fix this, but I've lost my bearings a bit (sheer number of files in a plasmac install!). I've run the config wizard, but on trying to open axis (via terminal command, as per guide) I get the error "incorrect [TRAJ]LINEAR_UNITS in ini file", which I don't understand. It says LINEAR_UNITS = metric in mud_plasmac.ini, which appears valid.

My initial config was made using the 7i96 wizard with a few tweaks, and it seemed like the contents of io.hal didn't make their way into the plasmac config. Correctly or not, I've put the contents from io.hal into mud_plasmac_conenections, and I can home and jog the machine.

Try mm instead of metric.

Works

I can't get it to do the test probe, the button just immediately lights and starts counting down - any ideas? I'm assuming it's something daft...the float switch seems fine, so I'm assuming it's config.

Your Setup Speed is wayyyy too low.

We're close...it probes - is it meant to be Setup Speed that controls the speed of the final movement up (to the height where it waits for a pierce command)? It doesn't seem to be, but I can't find something else to alter (it's too slow, and on an unfortunate motor resonance).

Setup speed is all Z axis motion except for:

Probing, but probing maximum speed is setup speed.

THC, which can use Z MAX_VELOCITY if needed.

Looks like it's the slow (second) probe speed I can't find - apologies if blind, but where can I find it?

The final probe up speed is always slow to maintain accuracy.
You must have a large hysteresis on your probe switch.
You could try reducing probe speed to reduce the overrun.
You could also try reducing the debounce in the <machine-name>_connections.hal file.
