I recently bought a second Mini with 1.1.0.11 which would not run the cooling fan in simplfy3d. I set the firmware back to 1.0.2.2 (to match my other one) with Cura, but now the extruder is running very at a very low rate (step = 833), something like 10mm requested only goes 1 or 2mm. Is there something you can suggest that would help me workout whats going on?
