I am having a problem with my Z axiz stalling on my Harbor Freight Round Column Mill. I just converted it to ball screw from using the fine feed worm gear that is built into the Z axis. I didn't have any problems with the old setup as far as the axiz diving into metal without stalling but since the conversion i can't seem to get it to feed into the metal without stalling
My motor is a Sanyo Denki 720oz in motor 12-300VDC 6.0A with a 20 tooth gear on the motor and a 33 tooth gear on the ballscrew i have the steps per set at 16500 which is giving me the correct accuracy i just lost all sorts of torque what can i do to get this back. The current on the Gecko G202 is set at 270K ohms it calles for a 285K ohms resistor but i can't find on the closest i could come was 270K ohms. I have these same motors on my X and Y axis with no problems i would think the motor specs would have enough torque to drive the axis direct without using gear reduction
