Test cube is half the size it should be on test print.

I ment to say I double checked it. The stl says it's 20mm all sides.
See picture. This is the stick test cubes size.

OK. I don't use CURA but I fired it up and saw what you were talking about.

So that would seem to leave your duet configuration wrong as the problem BUT you verified movement by measuring.

From the DWC console execute a M579 and see what it repots.

Made a test pattern to measure 25mm on each axis and jogged to each. They are exact.

One forum said it might be z accep and jerk are to high. Any clue were this would be?

M579. Axis scale factors x1.000, y:1.000 z:1.000

So M587 is not the culprit either.

I don't think your acceleration or "jerk" settings are too high. They are higher than mine but I don't think it would drastically affect the size.

Duet recommend cura so that's what I installed.

CURA is fine based on the large numbers of users.

I just never could get good prints out of it using it's typical settings.

Since my "goto" slicer works for me I have never taken to the time to work with CURA to get good results.

I downloaded a different slicer and will run it tonight just so I can say I did.
Let you know tomorrow
