Mesa 5i20 Plasma with THC using servos. was created by tzak
I wanted to get a thread started on setting up a 3 axis plasma with THC using the Mesa 5i20 card. I know that there is some documentation with regards to stepper configs however I wanted to see if anyone has had any success using servos and the THCAD from mesa. I have a 3 axis router using servos and the Mesa card, however I wanted to know how I can modify what I have to included THC and what other hardware I will need.
thanks

Basically any signal that goes to a stepgen in a stepper config just gets sent to a PID in a servo config.

This is my stepper config using THCAD but like Andy said the only difference is the servos vs steppers part.

Thanks for the reply guys.
I guess my main trouble is configuring what I have working into a plasma system. I have looked at your code John and am just not sure where to start modifying and what I need to leave behind as far as the THC goes. I understand that the stepper vs servo as far as EMC2 is concerned shouldn't really matter. But like I mentioned what should I change/add to the config I already have. This is a slightly modified version of the m5i20 config that was in ver 2.2.1 I believe which I have running a 3 axis system. I attached the files below.
If you can point me in the right direction I would appreciate it.
Thanks

I'm guessing any sections in the hal files clearly marked THC would be a good place to start...
