How does this Axes configuration look.

Below is my axis configuration info. Duet wifi & Duex5 . Please check and see if anything is off.

You've got a different acceleration for U than X. Shouldn't they be the same for IDEX?

Yes X&U it should be the same, Good catch. I am trying to optimize the printer.
