The motors for the x and y axiis are directly coupled to the ballscrews. The motor for the spindle z axis belt drives the spindle ballscrew--the pulleys are still 1:1. The ballscrews are 5 tpi. The motors are 110v 5.9A 1800 rpm. The power supply in the bandit that the mill originally came with is only 60V though. So ya, I suppose if I changed the power supply too I could close to double my max feed rate. I'm just thinking there must have been a reason spindle wizzard matched the 60v power supply with the motors in first place. Opinions anyone?
