Haha, if you find a spare one can I have it.

I'll have one too.

ohmic sensoring coming soon. doing it a little differently to most by using a THCAD10 (Not the traditional THCAD5).

Hopefully in a few weeks it will be up and running

Its all in place and connected. But i can't make it work.

Using the halscope i can see that I have 28000 when the torch touches the table and 36000 when its not touching. However i cant make this work in the Hal files, nor can i get the ohmic sensor light to light up when touching the torch to the material.

Also the encoder count continues to climb.

What have i got wrong??

 

Great you now  got ohmic sensing sorted and working with a THCAD-10 and my ohmic3.comp.

It was just a matter of connecting the pins to plasmac and being an older config, twopass was not enabled which prevented using seperate hal files.
