I have been doing a retrofit for my school on their broken compact 5. My current issue is finding a way to power and control the stock spindle motor. Any suggestions on how to control the spindle and what electronics i need. The stepper driver is a gecko g540 and I am using mach3. Also does anyone know how to do the macro for the tool turret?

Here is a pic of the machine currently.

I rebuilt my machine, Daniel, about 12months ago. I used a DC power drive from Parker drives, here in the UK. This takes the spindle on/off signal from your breakout board and also a 0-10v speed control signal. Works well. I have developed a macro for the tool turret, if you want it.
Best Wishes

So.. Parker makes DC Drives for these spindle motors?.. Nice.. it might be something for my lil' EMCO..

i'm not Using Mach3 Though.. i use EdingCNC instead..

i've found that the Emco 5 Compact CNC is very accurate.. at the moment i'm producing Titanium watchcases.. 2 weeks ago i made the casebacks.. tolerances of 0.01mm.. i only had to adjust the diameter twice in a series of 52 parts.. all done with only one tool.. ain't that something?
