How do you change the unit sizing? The DRO on my setup currently displays thousandths of a degree, which is far more precise than I need.
You need to open the screen in one of the editors and then change the format string of the DRO, for example it may be %4.3f and if you change to %4.1f you will only have one position after the decimal.
One revolution per unit is too coarse for me, but one degree per unit would be just fine.
You could command 0.0001 of a revolution so it would just be as precise. You would have exactly the same steps for a full revolution no matter whether your revolution was 360 units or 1 unit. It may however be easier for you to have your units in degrees depending on what you are doing, for me the amount of turns are what determines the required values of the coils so it makes sense for me to use 1 revolution as a unit.
Does the Rot Rollover affect any internal counters, or is it just a modulo 360 on the DRO user interface side?
Not a clue on that, think Art would likely be the only person able to answer that properly.
