I'm trying to turn my milling machine into a CNC so I bought this motor driver on ebay.
https://www.ebay.com/itm/DC-40A-DC-...e=STRK:MEBIDX:IT&_trksid=p2060353.m1438.l2649
The only problem is I can't seem to find any device that can regulate the resistance across 9.7v at 100KOhms which would allow me to control the motor speed from my program. I was recommended to use digital pots but after a long search most are only capable of handling 5v.
Any ideas on how I can solve this? I just want to be able to control the motor speed from my pc.
The motors I'm using run at 48v (continuous 5.8A, peak 30A)
