MicroRouter Spindle upgrade - advice and help required

The BoB you have, I am certain, has 0-10v output to control spindle speed with a VFD and Spindle setup, so you don't need any more electronics apart from the VFD. The rest is setting it up in Mach3.

Thanks, so which spindle should I be looking at bearing in mind it is for finishing only so RPM is more important than power.

you may need a new psu to meet the spec of the new spindle

I can't recommend any spindles as I do not know the run-outs of any. I would reckon a 2.2KW spindle and VFD kit would probably do, but it sounds as though you would want quality rather than cheap Chinese.

I probably can't afford quality so would settle for Chinese.

Have you seen this? https://www.youtube.com/watch?v=jfryQr10nbo - someone has added a 1.5kW spindle to a micro router.

Thanks for that it's ust what I am aiming at.

Just a quick update to let you all know the outcome.

I ended up buying a serial to RS-485 adapter (less than £3 on fleabay) and downloaded a plugin to ebable Mach3 to control my spindle directly.

The new spindle is fitted and running and I was originally using a 5 gallon drum for a water reservoir but this didn't stop the temperature hitting the mid forties centigrade during the hot Easter weekend. I have to point out my workshop is upstairs and the room temperature was in the low thirties. As downstairs is always a lot cooler and having plenty of plastic pipe to hand I simply added about 15 metres of pipe to the outet and ran this downstairs then bak to the tank which solved the cooling problem.
