error after Plasmac setup

But if you go to the trouble of ordering a THCAD, you might as well add a 7i96 to the order and be done with it. Its really the cheapest THC available.

Even cheaper without the 7i96

The plasma cutter i ordered has a 1/50 torch head voltage divider built into it. couldn't i use run that into and arduino analog input then write a bit of code to output one pin or another based on voltage readings, then i could use Plasmac mode 2 for the z control

That would be possible. Mode 2 was really designed for configs where there was an existing external THC (Proma or similar).

It does work with arduino, but the 1024 values are just enough to do the job.

There are some other higher precision A-D converters that are compatible with the Arduino. I've got one here. but have no idea where it is to give you a part number.

Thanks but no thanks, i went that route once before THCAD came out, costed way to much time and money with the the end result being a to damn fast THC that can not be used at those speeds. Also got some TI voltage to frequency converters sitting in a bin somewhere in the shop, never used.
At the price the THCAD is, nothing else is reasonable, nothing! Not even an arduino or ESP32 (have plenty of those too) with it's 12 bit inputs and two processors and wifi and bluetooth connectivity built in.
Made two of those, one is working every day for some years now, the other is dismantled here to remind me not to go that route ever again!
BTW, thank you very much, Peter.
