Lathe Machine Retrofitor:
I have tried many ways to tune the spindle
The CNC controller is GSK980TDC and the spindle
is GS3048Y-NP2-ZJY182.2.2BH-B3Y1
motor but even though it gets better
it still has too much vibration and hunting.

CNCmakers Support:
For spindle vibration, please set: PA15=1200, PA16=2, PA18=120, PA19=30, PA25=0
