Alternative THC recommendation?

Those are the configs i used, modified from THC300 config to be fully automated, for parallel port and several Mesa boards. They have been in use for several years on several production machines and they never fail.
And these are new machines i am building and they will use Plasmac with THCAD:

Personally, i am sure there is nothing better than PlasmaC in combination with THCAD, not even in the "industrial" range of machines costing north of 100K.

you can try mine its opensource based on esp32,, it act similar to THCAD but with GUI (even better its 12 bit)

for software use Plasmac with voltage float in

Where can I find that?

That is as simple as making a voltage divider, wiring it to an analogue pin on esp32, and using that to produce frequency on one of the outputs depending on the voltage input, adding an opto coupler to that output to have it completely isolated from the plasma.
Or it can be programmed to output arcok, up and down signals, that should be even easier, as the first version to do it right would require using built in timers and interrupts to get a very stable frequency, and very high at that.
Arduino works at 8MHz, ESP32 at 240MHz, has two processors and some other hardware besides wifi and bt and hal sensors and ........

its up now
github.com/taloot/TalooTHC

i update the GUI and add graph,, also averaging for analog and capacitance for smoothing , adjustable in GUI
also epprom save for settings.
