Nah you have some other issue that's causing this. While these machines are rubbish in lots of areas they are stiff enough to cut Acetal at 1mm DOC.Quote:

Just for testing purposes lower the velocity for each axis by 50% and try cutting again at the 1mm Doc and see what happens.
Edit: Just spotted that the Motor tuning below is not yours so what is your tuning set at.? The figures in the tuning below are about where I would expect for this machine and why I said to only low velocity not acceleration as this is on the low side anyway. If your acceleration is much higher than this then lower that also by 50%.
I have cut anodised alloy at 0.5mm depth with those settings, so I agree with Jazz that you haven't fixed it yet!
Yeah after some more testing I agree with you as well... :-/Quote:

I've played around with the motor tuning (speed and acceleration), but it hasn't changed anything.
More testing to be done at the weekend, I guess... :-)
