The configuration wizards don't really work for this application. If I remember right I ran one config just to look at the files it produced it think I told it a 7i96 mesa. You'll end up with a bunch of stuff that is clearly mesa specific. I'm thinking I copied the qtplasmac stuff out of that file though. But the files I posted I just started with the basic config that comes with the remora files from github. Hence why they are still named ec-500, I left the remora related stuff in there pretty much untouched, and just started adding to it. From there I started working through it adding one pin at a time. Using halshow in qtplasmac is going to be one of your best friends through that process. Did you build.your own divider? The plasma cutter were using has one built into it. We currently have a standalone thc (proma sd, it came with the machine, wouldn't have been my choice) on our machine but it doesn't want to play nice with the divider that is in the cutter. Plus having the thc on the main control screen would be much better that a standalone thc unit. What I'm currently thinking is to put the arduino in the box that our current thc is occupying and where using modbus comes into play is I should be able to send the data back to the computer over ethernet. I'm trying to avoid using usb to avoid as much potential for interference as possible.
