Raspberry Pi4 Hal configuration for torch on

Moved to PlasmaC.

PlasmaC uses spindle.0.on but that is done automatically by the Configurator so you shouldn't need to specify that.

Did you use the Configurator to create the configuration?
linuxcnc.org/docs/2.8/html/plasma/plasma..._to_the_base_machine

Can you compress your configuration directory and post it.

That archive has copied files rather than links so I canot tell what type of installation you have.

Is it a Buildbot install or Run In Place?

Are you using LinuxCNC 2.8 or master? (not that it should matter but I want to check why the Configurator dodn't work)

I also don't see the backup copy of your original ini and hal files.

Did you follow these instructions ?

EDIT1: I have also noticed that your [AXIS_L] and [JOINT_n] MAX_VELOCITY and MAX_ACCELERATION values are all over the place. In your base machine setup they need to be identical for an axis and its corresponding joint(s). Also STEPGEN_MAXACCEL for each joint needs to be at least 10% more than MAX_ACCELERATION.

EDIT2: You have set PlasmaC as Mode 0 but I don't see an arc voltage input. Are you using a Mesa THCAD or something else for arc voltage.

EDIT3: You have in your hal file "net plasmac:cutting-start => hal_pi_gpio.pin-32-out". This should not be there. The first line in the instructions state:
"You NEED to have a fully tested and working base machine configuration without any connections to plasma specific equipment before proceeding"

For Mode 0 you need arc voltage so PlasmaC can calculates the Arc OK to begin a cut after piercing and for THC.

For Mode 1 you need Arc OK to begin a cut after piercing and you need arc voltage for THC.

PlasmaC reads spindle.0.on to start a cut sequence, you don't connect anything to that.

You need the torch-on signal from PlasmaC to turn your torch on.

You 'could' get away without an arc voltage BUT you would have no THC.

You would still need an Arc OK signal.
