>And then tell us how it works when you've lived with it for 2 weeks. Remember, the original was using a PIC microcontoller to read aound 10 pulses/rev from a spindle encoder to provide a tachometer, one ppr is fed to mach 3 to coordinate Z axis movements. The microcontroller also controls the stepper speed, direction, ramp up, ramp down. It was almost like having a stand alone spindle controller. I could probably do the same with an arduino I've got kicking around somewhere, but where's the fun in that when I haven't a clue how to do it in Linuxcnc but would like to have a go? I need more I/O to start, so that means a mesa 6I25, or more likely a 7I92 given the micro motherboard I have. I have a Gecko G540 which currently get's shared between lathe and mill. I'd like to keep that for the mill, but maybe find something else for the lathe. Once I have all that figured out (overly optimistic?) I might just start with the hardware. That might be OK if I didn't have 25 other projects plus I dread to think how many "honey do's" bubbling up right now. >A question though, that 1800+ motor is going to be heavy, heavy enough >perhaps to pull the Sherline out of alignment?

Thank you very much for your help with this, I think I avoided a potential mistake.
