On microstepping, we are currently using 16th microstepping and motors with 200 steps per revolution which in combination with our drive sprockets gives us .02mm X and Y resolution. My research has shown that with higher fractional microstepping comes a reduction in available torque and that increased microstepping while providing smoother quieter operation and higher resolution does not significantly increase the accuracy of the printer.

For this reason we haven’t looked into dividing our steps further. Perhaps these limitations do not apply to newer drivers. What is the make and model of the drivers your system uses and how does the missed step detection work? Our drivers are Allegro A4988 chips and we use external linear encoder based feedback for skip correction.

In the future, we are thinking of 32 bit Marlin based boards as well. If you have any suggestions or thoughts on this, pleas share.
