variable speed for 24v dc motor ?
This spindle looks like a steal @ $100. The seller also offers a complete engraving router with this spindle but it lacks
variable speed except for the step pulleys. It needs a 24v power supply 5A minimum.
Question: How difficult would it be to make this variable speed ? Some cheap plug-n-play board available ?
Keep it simple if possible, electricity is black magic to me.
