I am looking at the Chinese spindles now.

There is this one from Aliexpress, which is very cheap, 500w, free delivery, and claims runout of 0.01-0.03mm.

There is a reference voltage input on the PSU so speed control can be hooked up to the controller board very simply.

The maximum RPM (15k) is only half that of the Dewalt. What kind of RPM range is ideal for the MPCNC?

Edit: While I’m here, questions about speed control/torque.

With the speed reduction function on these, does the torque go down with the speed? How does it compare to speed control on the Dewalt?
