Qtplasmac- Auto Z axis movement not happening with thc proma 150

Hi All,

I am using 7c81 board, raspi 5 with thc proma 150. I am using QTplasmaC 
The gpios and leds for UP, DOWN, Arc OK are getting connected and blinking.
However, the Auto Z axis movement not happening with thc proma 150. Attaching the files for your reference. Please help.

What settings are on the Proma THC150 ?

Voltage is set to 100 and H-t to 5.

On the Proma, the first and second settings should be set at minimum, i do not recall what was the third and forth settings.
Only after having this work you can set voltage higher if it wobbles a lot while cutting.

hi,

The Z axis DRO will not move in spite of the following in Raspi 4/5:
a. torch on
b. THC enabled setting
c. HALSHOW is showing move up and even.
d. After trying the changed settings mentioned previously on proma.
e. Mode is 2 for the external THC
Please help as I have been trying to do the same for few weeks now and let me know if any settings need to be added in the HAL or ini.

Does the machine reach the requested speed while cutting?
If it does not, it will not turn height control on.
What are the settings on the Parameters page?
Set the VAD to 60% first and try again.

hi
Machine reaches the requested speed while cutting. 1000
I have all the default settings on the Parameters Page.
Tried with VAD 60%. still does not work.
Also M3 $0 S1 does not work.

Can you upload a back of your configuration made from clicking BACKUP CONFIG on the settings tab inside of qtplasmac please?

Thanks for your reply.
Please find attached my back up config.

Also I do not want G53 in my code when I load any .ngc file. Please help as I do not wish to install limit switches to my system. I want to use G31 instead before the cut starts with THC.
