Mesa Board(s) Question for first time CNC Plasma was created by Mr S
Hi there,
So I've been going down quite a few rabbit holes the past few days as I'm going to make my own CNC plasma this spring. I've gotten to the point where I think I know what I need to order - sort of.
I orginally wanted to do a Pi4, but have decided to do a standard computer setup and that will eliminate me having to make the kernel real-time on a desktop (as long as it's powerful enough, which I can get a pretty good one for $200 on Amazon).
Now, from what I have figured out, with the 7i76e's being out of stock, it appears as though the replacement is the 7i96S (just with a few less outputs I believe).
If I go with a non-HF plasma cutter that is THC capable such as this one , do I need to get the THCAD controller Mesa card as well? If so, since this is a blow-back plasma cutter (non-touch) I'm assuming I need to get the THCAD2 not the THCAD-300?
Thank you for any help you can provide. I'm going to do this in stages and would like to get the Mesa cards first so I can play around with them a bit before my next paycheque to get the cutter.

From the link you posted:You should really take the time to read stuff and not go by the hunch, that is not a blow back plasma, and it does requite THCAD300 as the voltage output is 1:1 noted above.
Still, I would suggest you get the THCAD5 or THCAD10 or THCAD2 and 2 of 1MOhm resistors, just in case you decide to change the plasma later on.
CNC Plasma Cutting Machine : have 2 pins and 4 pins connecting port at rear of machine. 2 pins connector for The arc voltage output ratio 1:1, 4 pins connector for Signal Control.Easy works with CNC cutting table.The plasma cutter with Non-HF Pilot Arc function (Not HF Pilot Arc) Under this function, Pilot arc will not interference to machine...Still, I would suggest you get the THCAD5 or THCAD10 or THCAD2 and 2 of 1MOhm resistors, just in case you decide to change the plasma later on.

For HV/HF pilot arc THCAD5/10 is the correct option
but what resistors must get in case of around 2mhz/10+ kV HF/HV arc ignition ?
any tips to not burn THCAD ?
Any other alternative options for HF/HV pilot arc for reading cutting voltage except THCAD?
