Hi Roy, Thanks for the advice, I shall get some cable and try a rewire ...  I tried another computer as suggested by Rich, and that did not work. Regards.

FAQs / Help wanted. Chinese 3020 Motors make a grinding sound. Particularly on Xaxis +.

Hi, I am a newbie to the forum and to CNC machining. I bought a Chinese 3020 and have a problem with a grinding noise coming from the stepper motor on the X axis positive when jogging, and then it appears to be across both axis when running a program, for example a circle where it becomes very noisy as it gets toward the zero movement. I have played with acceleration and had slight improvement, but the problem is still there. Also interchanged the motors to test, and the problem remains mainly on X axis. Sometimes the motor will actually stall. Any help would be appreciated.

Hi, I am Tipsydog,
I live in central Victoria Australia, and a retired engineer.
I have recently purchased a Chinese 3040 CNC router and have added Mach3 fully licensed.
I have a problem with the X axis making a grinding sound particularly in the positive direction.
I have swapped the stepper motors and leads with no improvement.
Also fiddled with acceleration and velocity and still have the problem.
Wondering where the best place is to post a query on this issue.
I would appreciate any help on this.
