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...

Until you know there is noise on the analog input from the Acorn, then it could be internal noise in the driver converting the analog signal to digital. When running the driver in test or jog mode, the up/down buttons generate digital signals, not analog ones that route through the analog to digital...

Do you even know if it's interference? Have you looked at the signal when the inverter is running? Is interference visible?

Immediately after the weird moves with the parting blade, what happens if you restart the program from the beginning? Does the first tool run correctly?

It may be a problem in the analog to digital conversion within the servo drive. Unless there are some filtering parameters in the drive for the analog input, then you may not be able to to fix it without changing the servo drive.

You might want to check on the Eding-CNC forum. This forum is for Centroid CNC products.

Of note, the Acorn kit comes with all of the necessary cables, including a shielded Ethernet cable.
