Hi All

Concluded after tests  that the problem only exists when either the Feed Rates are to high
or the cutter motor is running.

The wiring for this DC Brush motor is quit separate from the stepper motors,
however the power supply is part of a multi-rail power supply.

Before I go and separate them totally, are there any settings that will improve immunity to motor noise ?
The speed is probably proportional to noise level at the wrong frequency, so slowing it down may resolve it.
However I need to totally eliminate the affect to gain confidence in the system.

Drifting X,Y,Z values.(SOLVED)

Hi All

Reducing the Motor Speed to 14000 (from 20000 ??) ,fitting chokes on 24vdc power cables and Common
has completely eliminated any X,Y,Z errors.
Learning a lot more about Mach3 also helped.

Have you verified that the cutter is not pulling from the holder?

Hi All

Yes, I did that initially.
The speed settings were definitely to blame.
I have engraved about 50 discs since slowing it down and have not had one error since.

Many thanks for the replies.
