Increase the feedrate or the depth of cut to make chips break.

Well, since you posted in the Centroid CNC forum, you are halfway to a solution. The next part of the fix is here: https://centroidcnc.com/

Could be a bad encoder. Could be a slipping coupling. Could be a bad electrical connection. Could be a bad power supply. Could be a bad encoder port.

Or, you can switch to an Acorn6 that has multiple encoder inputs.

You'll have to set your Ethernet adapter fixed IP address as well.

The easiest way is to just copy the CNCT and Intercon directories from the old drive to the new one. No need to reinstall anything or restore reports. Be sure to run the tuner and check for communication errors.

Not relevant. The only thing Centroid cares about is the spindle.

Marc already explained this. At 1000 meters/min, you are already at your max rpm at the stock diameter. There is no way for the spindle to increase any more when the part gets smaller.

The 2K series resistor just drops the voltage. Save yourself trouble down the road and connect them according to the manufacturer of the CNC control who says to use the DB25 connector.

The fact that it does not return to zero, implies that you are overdriving your motors and loosing steps. What are your programmed feed rates for the grooving tool? Common mistake is to program a valid range in feed per minute, but have the feed set for feed per rev. That will almost always cause mi...
