Help with plasma controller build

[Clive S]

I found this calculation online saying
take the square root of the motor inductance which is 3.8mh
times it by 32 and this is the voltage
is this the wrong way to calculate?
thanks again for the help

the pmdx 126 can only be slaved if used with pmdx 134 I think

Well you are using Gecko drives so why not take their figures? I take it you are using nema 23's motors, It will run fine with 62V but you will get better performance with a little extra.

I don't see in the manual re the 134 slaving it just looks like a breakout board for the gecko.
