QTPlasmac pierce delay handling

Get a "reed contact" or "reed relay", make some 3 turns of the clamp wire around it.
That is it, cheap simple and never fails.
I am sure it was in the PlasmaC documentation, no idea if it is in QtPlasmaC.
See attached.

QTPlasmac pierce delay handling

Category: Plasmac

Unfortunately the relay in the unit is damaged and does not close. I ran through the diagnostics in the service manual to come to that conclusion and of course the service manual recommendation is to replace the inverter board which is half the cost of a new unit lol. It's also very difficult to access but some point down the road I will pull it apart and replace the relay on the board if possible. I'm going to try Tommy's suggestions and hopefully that will buy some time until I fix it or sell it and get another unit.

Feature Request: ramp piercing (aka moving piercing)

Category: Plasmac

Sorry, I did see the previous post but it's from a year and a half ago. I guess I should have asked if it had been merged into 2.9.4 and/or master.

Mesa 7i97T & LinuxCNC setup struggles

Changing the PWM scale changes the scaling of all PID parameters.
That is, a P term of 10 with a PWM scale of 10 is the same as a P term
of 1 with a PWM scale of 1, In both cases an error of 1 mm generates a
full scale (+ or - 10V)

There is no reason on a torque mode drive to change the default 
PWM scale of 10 (a scale of 10 means the PID output is scale in volts)

QtPlasmaC using w axis

Category: Plasmac

I need help. I tried converting the a-axis to w, making it leaner. However, I keep getting errors like dro_a and torch_a. Is there an easy way to add a w-axis as z2 ? I made it by editing the handler file and ui file  to overcome these errors; however, I can get it to show the z2,  i looked at the QtVCP library there is z2 there
