hello I have done retrofit whit 5 Emco machines on Mach3 and I am busy whit the 6 one I always let stay the DC spindelmotors on it but I make a small modification on the spindelboard and I put a small pcb in that I have made for to control the DC spindel motor whit Mach3 are another program but you have to put a PWm signal in the small PCB board so I can change the speed in the spindel from 400 till 4000 rpm.
The old stepmotors for that I place new in it and new power supply whit a LeaveBoy 77 USB controller.
The only thing that is not so stable on the Leaveboy 77 card is the speed masseurment.
it si not a problem to separte the DC spindel board from the rest of the elektronics.
