I'm rebuilding a R2X with a DuetWifi board (my second build) and have it all working relatively nicely. One thing I've noticed is that the steps/mm with the stock (1.8 degree) extruder motor and extruder is very low with 16x microstepping: 96.275! From reading prior posts I get the impression that this is quite low, that I would ideally be in the ~800 steps/mm range (e.g., where a Titan Aero would be).
Because this printer doesn't have a very large build plate, I was thinking of trying to tune for relatively thin layers (0.05mm?) and more detailed parts. I'm concerned that that E resolution won't be adequate, but I'm neither sure how a problem would exhibit itself nor how I would detect it with Duet diagnostic information.
Beyond that, I'm interested in thoughts on use of higher levels of microstepping. From reading prior posts I understand that this creates more work for the Duet, but I suspect I can push this up to 32x+ in this scenario without worry? How would I know if I had asked too much of the Duet?
In the mean time I've found a Moons stepper with similar torque and 0.9 degree steps to get me into a better regime w/out leaving 16x microstepping. The PS has been upgraded and should be fine with the increased current requirements this entails. Of course this too increases the work for the Duet, but feels like an obvious first step.
Thanks in advance for your help!
