Hi,
My name is Anthony, I am new to the forum and new to the CNC world. I acquired a taig 2027 CNC micro mill to serve as a learning tool for me to gradually lead into the CNC and machining trade. After buying the Mach 3 software and the necessary adapter board to finally get this older mps 2000 controller running and communicating with the computer, I was finally able to get my machine running. After a few test programs, I noticed that my stepper motors were stalling while in jog mode. I tried motor tuning, loosening the gibs on all axes, and adjusting the motor couplers but nothing seemed to work. After doing some research, I realized that resonance is a possible issue, so I decided to completely take the motors off the machine to see if this was the case. When I removed the motors and tried to jog them, they instantly stalled. It seems to me that there is absolutely no torque given out by the motors and all they do is hum. I know for a fact that the motors are not bad because I ran a few programs before and everything seemed to work out fine.
Basically, I have been at this now for the last couple weeks and I am not sure exactly what I should do. I would really appreciate if someone could steer me in the right direction as to what my next move should be. If my issue is truelly a resonance problem, I would appreciate if someone could tell me where I need to measure the current and voltage from so that it is set correctly. Any suggestions would be greatly appreciated as my frustration with this machine has reached its highest point. I hope to see some chips flying soon! Thanks.
