Though rated at 5A, Im pushing 5.5A thru it.
It does move the quill, its torque to drill or mill isnt enough. I could do better w/ a hand drill.
It will drill aluminum using 1/4" through 1/4", but feedrate has to be F1.5. I had feedrate at F3, it would stall.
Crap !
The driver is 6A, PS is 48V 7.5A.
Now to purchase another motor, which should have done the first time.
NEMA42 3256ozin, rated 32.6W. 6A
If you really believe any of those ChiDingaLing motor specs.
