I am not sure where you post "wish list" items, but I sure would like to see the ability to specify encoders for all 6 axes. I am currently using encoders and a brain to detect racking of the gantry. The Y-axis and B-axis motors are slaved. I am currently having to specify the b-axis encoder as being connected to the x-axis and that is causing the brain to fire anytime I zero the y or x axes. I could address the problem if I could specify an encoder for the B-axis.
