So I have my MPCNC operations and ready to go, but I need to pick a spindle. I was hoping to get a large 3 HP spindle with a VFD controller, but the bolt holes are 3.18 inch width and the MPCNC looks to be about 2.5" between the roller bearings that the spindle would mount to. I know I can design something to space it out a little and get it to fit. I wanted to ask if anyone else has mounted a larger spindle like this to their machine? How did you mount it? And if you had any problems with the heavier weight motor?
I’m looking to cut aluminum so I thought, what the hell, why not just get the biggest, badest spindle I can!
