My first post is pretty straightforward: what do I need for a spindle? I’m currently printing all the parts for the MPCNC and I’ve been looking at ebay and AliExpress for budget ~500W spindles. Some come with just the spindle and others come with a power supply. If I was already going to use an ATX PSU for the rest of the build, are there spindles that run off 12v? all of them seem to say 110-220v which I assume are the mains for the PS supplied with these kits. If not, and I do buy the spindle with the PSU will that work with PWM? I’m guessing there isn’t any sort of speed controller built in so how would you guys recommend going about adding that feature?
Ideally i’d like a 500w spindle, pwm so I can control speed in the gcode. preferably without needing to use two power supplies.
