I am now finding my CNC skills, learning and ability to make what I want is being hindered by my Spindle Motor setup which I never really managed to get running properly with the Mach3 PWM and ended up running my Mill Spindle with an external Pot hanging out of the controller.
Anyway, the limitations of having this thing revving its nuts off at 10,000 revs max, its time to move on only this time I want as much advice as possible before I throw more cash out the window.
Im looking at a water cooled 800W Spindle Motor and a 1.5Kw VFD on FleaBay (

1. I dont seem to be able to find any way to interface this into Mach3 other than a straightforward On/Off
2. Looking at the termination panel image I think it looks like I could use a Charge Pump Circuit from the PWM output on Pin but Im not too sure.
3. Is it possible to control the Motor Speed with Mach3?
4. Where does the water bit come into the equation, How does the water circulate?
5. Do I need a circulating pump and a cooler setup?
6. The run-out claim of 5 microns seems a bit farfetched what can I expect the run-out to be?
Has anyone bought one of these and what are the pitfalls?
Can anyone give me a thumbs up on this please.
