Hi, I have been using what used to be a CNC Router, and am using it to hold a Laser head to do some marking. I needed to add a spindle (chuck) as I have some parts that I need to spin at no more than 30 RPM. Rather than going out and purchasing a VFC/Motor to drive the spindle, I started experimenting by temporarily using my Y axis motor (disconnected from the axis itself). I set up the parameters for the spindle according to the instruction manual, but so far have ended up with the motor running too fast, too slow, too hot. I just can't seem to get the right parameters to make it run the speed I need. Here is what I have.
Stepper Motor - 4 wire, 2 phase, 1.8 degree step angle, 3 amp, 3.6v
Motor Drive = 2 Phase, 2000 pulse/rev, 3 amp current set, half current mode set.
Pulley ratio, 2 motor rev = 1 spindle rev
I would be so grateful if someone could suggest the base parameters for the Motor Tuning and the Spindle Pulley settings, as I have tried so many combinations, I don't know what to adjust any more.
Cheers.
