I picked up a 4x4 K2CNC. It has 2 issues that I see... so far:
1) The Z servo has a bent shaft & won't turn. I can't find a replacement servo. (D860-30B7-TC9) Any other options? All 80mm servos seem to be 750w+ and DAE HWA no longer makes them.
2) It needs a new control system. I removed the Gecko drives. It has a pair of G320's and a pair of G320x's. I want to control everything with a Mach4 controller. The problem is the Mach 4 has 4 output wires per channel (2) pulse & (2) direction. The Gecko has only 3 input wires- Direction, Step & Common. Can these work together?
Or... Am I better off buying all new closed loop steppers and just have 80mm adapters made?
I've run & repaired various CNCs and Lasers, but control systems is new to me. Have lots of low voltage DC, Arduino & Raspberry Pi experience - so I know enough to know I don't know anything.
Any help would be fantastic!
