Ok. time to consider the electronics. I am looking at the CNC Xpro V3, with 4 NEMA23 motors. I also am looking at the 400w spindle from Spark Concepts. Now the board has a max of 24v, but the spindle is suggested to use 48 v for full range of speed. I am thinking I am looking for2 different power supplies, unless someone here has a better idea.
