Odd CoreXY behavior

[eroth3]

I'll keep it short, when I set my duet to 16x interpolation on microstepping everything works great. If I change to any other setting only changing my mm/s to reflect the difference my X and Y move diagonally when i try to make straight moves. They are moving at an odd angle with the two steppers running at different speeds. Other than that MAN do I love these electronics. Everyone involved deserves a lot of kudos.
(edit) - ive been using the web configurator to make all of these changes…if that helps.

Check the M350 line, the configurator has an error. It thinks there's only the X axis.

It outputs:
M350 X16 X16 X16 X16 I1 ; Configure microstepping with interpolation

Corrected version:
M350 X16 Y16 Z16 E16 I1 ; Configure microstepping with interpolation

Actually, unless you change it in the configurator, by default it outputs I0 at the end (without interpolation) so it needs to be changed to I1 as well.
