New Project with Mesa 7I96 and THCAD-05

Awesome thanks

I got the machine cutting and working still need to tune some minor details but so far working.
I have the thcad-05 and was trying to hook this up but was trying to see where they are hooking up the output to from board to circuit?

Similar to the THCAD-10 in the pic you have connected but use the ENB+ and ENB- instead of the ENA ones.

Wire it as shown but leave the AC relay out and follow the notes below the thcad. (as Phill says use ENCB)
Install the correct bit file
add this to your hal file (make sure the encoder.01 is numbered correctly)
Check to make sure
hm2_7i76e.0.encoder.01.velocity is showing some data in halshow. It should be hovering around your 0 volt frequency
Download ohmic3.comp from here and from the command prompt type You may need to install the linuxcnc dev tools to do this.
If a RIP build, drop the sudo


Copy this to your config directory, edit the data as required for your version of the THCAD-5


add this file to your ini file after your main config file
You should be good to go!

Ooops, looks like you also need this line in the hal file I shared

So I am guessing that I just change “7i7e” to my board 7i96

Gave me a error when installed the files but I do I need to have the card wired up when turning the 7i96 card to the enb? How can I check of the card has the bit file installed I think I had done it just don’t remember.

I see your comp file am I suppose to add that to my config file directory?

Well will have to wait on this ohmic part cause I am running a job that is a little bigger than my 2 inch test circles I was doing a couple of days ago and it looks like the THC is not working it’s not moving up or down. I see the voltage marking on the GUI and I am using the latest sheetcam plasmaC file that is in the sheetcam drop down.

It does not really matter as it will install from any folder but it would be best to keep it all together

You do have the THC enabled in the GUI don't you?
