Mine looks like this, is that a problem?
# ---ARC VOLTAGE ENCODER---
net plasmac:arc-voltage-in <= hm2_7i76e.0.encoder.00.velocity
setp hm2_7i76e.0.encoder.00.counter-mode 1
#setp hm2_7i76e.0.encoder.00.filter 1
setp hm2_7i76e.0.encoder.00.scale -1

So I finally got it working.
Problem is I modified a config file from linuxcnc 2.8
So I ran PNCconfig. And made a new configuration from scratch.
I figured out for some reason F/1 does not work.
Somehow changes to Qtplasmac don’t work if you run the configuration again.
Is this a bug?
I changed Jumper to F/32 and Made another configuration from scratch. Now it works perfectly.

Change from F/1 to F/32
And change to the 0 Volt frequency
Do not influence voltagedisplay.
However the change to 0 V frequency can be seen in the qtplasma…..new file.

That is the expected behaviour:

Hi to all so I am back after a ling break.
And I finally could start building my plasma table.
So far I got the tandem axis running which I chose to be the X axis.
Homing and everything Is running fine.
I also was able to Calibrate the Axis movement to within 2mm per 2 meters.
Dont have anything accurate to measure the movement except a tabe measure.
What is still have to do is to find out how much acceleration the Stepper motors can handle.
When i use the Motor tuning option in pnconfig. Only one of the motors is moving.
Is there a way to make both motors to move at the same time?
So far i use acceleration of 1000 and maximum Speed of 15000mm / min.
Seems to be running well without loosing steps.
What acceleration should I try to reach for good plasma cutting?
