thanks @twforeman

Thanks @jimf

Well considering that he advertises the runout as less than 0.005mm... 0.001" runout just below the collet might be okay. Can you test the runout further away from the collet? Say 1.5" down? The runout will most likley increase the further you are from the collet. Would a drill bit straight enough ...

I'm getting same runout inside hollow collect taper.

Hi Everyone, I wanted to upgrade my DC spindle to a more powerful spindle. I went ahead and bought, following combo for US$209. - 65mm ER11 1.5kW 220v water cooled spindle - 1.5kW 220v drive inverter VFD (WARNING: try to avoid this seller) http://www.ebay.com/itm/CNC-65MM-ER11-1-5KW-WATER-COOLED-MOT...

Thank you, I've sent a PM

Yes, I've tried that. When I did that, the new motor started to make the sound and the driver heated up (in the same socket).

Unfortunately it seems not the issue. But, thanks a lot for the input.

Thanks a lot for the reply. Let me give it a try and get back to you.

The driver at the top left socket is getting hot (as I mentioned above, if I plug a new driver at that socket, it gets hot as well). That socket corresponds to the left Y stepper motor. Other drivers are not hot.
