Hi, I am very new to all this xylotex stuff.
I have set up an X2 mill a Xylotex ver 4.00 4 axis
I have Step Syn motors 1.8A, I have wired them unipolar
I have set my vref's to 2.59 volts
I am getting jog control from mach 3 on all 3 axis
Problem - sometimes the motors when they stop sit there humming and making growling noises, it seems when I am jogging, all is ok, when i stop, motors are not happy. As i said, sometimes.
I have no idea what could be the problem. please help.
would it be because i have them wired unipolar ?
Thanks to anyone who might help
