Hmm, a bit more money, but a lot more bang for the buck. Looking at the specs, it appears that these drivers still work: https://www.omc-stepperonline.com/st...or-dm860t.html

And with a 3.3mH inductance, I am looking for a 60V power supply and 16amps total assuming 2/3 of the total amperage of the motors?

So this is a decent Nema 34 setup?

I am guessing that the 2/3 of the rated current of each motor doesn't work if each motor gets its own power supply right? If so, would I want to have a power supply that can provide more power than the stepper needs for head room such as this one? https://www.ebay.com/itm/400W-60V-6-...4383.l4275.c10
