Hi Guys, I hope someone has had the same problem. My spindle is quiet at low rpm but as soon as it gets to about 600 and above, it sounds like there is too much backlash between the gears. I have checked the gears and there is no wear on the faces and as there is no adjustment, the play between them must be correct. My guess is that the spindle motor is reaching the set rpm and then hunting to hold it. If I put load on the spindle, the noise remains the same. The digital reading on the drive fluctuates by about 10 digits. On my lathe the reading only fluctuates 1 digit, so my guess is the VMC control is hunting, therefore the motor speeds up and slows down thus causing the noise between the gears. Is there a way to adjust the drive so that it does not fluctuate so much? Any help will appreciated, thanx.
