Having problems with my THCAD-10

     
Hi, I have a new plasma machine which I bought recently that has CNC ports and has 1:1 ratio divider and am using 1M ohms at each leg of + and - of the plasma machine which will give you 21:1 ratio but the THC doesn't move up and down but I can see the THCAD-10 LED light blinking fast when cutting and blink slowly when not cutting. i have attach my logs.

Screenshot when cutting, not cutting, and settings page

the light on the board  shows your wiring to the thcad is correct.
Next step is to confirm that it is being read correctly by the mesa encoder.
open halshow and find the encoder you are using. Does the velocity pin ove at all or does it stay static.

If its static, then this is probably missing from your hal file. I thought it was added by pncconf

Once your encoder velocity is responding correctly, 
enter your thcad calibration data into the qtplasmac gui as per the instructions.

# ---ARC VOLTAGE ENCODER---
net plasmac:arc-voltage-in <= [HMOT](CARD0).encoder.00.velocity
setp [HMOT](CARD0).encoder.00.counter-mode 1
setp [HMOT](CARD0).encoder.00.filter 1
setp [HMOT](CARD0).encoder.00.scale -1

this is how it look like in hal. my board is 7i96s

 

       

Wrong polarity on THCAD input, or wiring not correct from THCAD to Mesa 7i96S.
Open the "halshow" and check if the encoder is counting correctly.

THis is the step I told you to do earlier but you didn't

Yes you did Rod, i just reminded him.
