@dogboy said in 5 Phase steppers (0.72 Deg.) using a SCARA system and Duet 6XD.:

My next question, is how can I use the M92 command to set the steps/degree if one degree of rotation on the joint does not give a whole number of steps?

Steps per mm don't need to be integers, you can use decimal points. See the example in https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_SCARA#example
