Re: DRO Prototype for Windows PC
Did some more checking on CNC conversion for my mill:
Mach3 CNC Kit With 3-Axis DC Servo Drive & PLC: $1795
Ball screws for mill $2,084.00
Assuming I could build my own brackets from scratch, make my yoke work and the 15 amp servos are big enough.
Then for around $4000 instead of $300-$400 I could convert my mill to CNC instead of DRO.

machines and tooling than it is on computers. It is probably harder on
drives than anything else.
