Hello all I had my R2 working great last night until what i was printing poped off the bed. So this morning i tried to do it again but this time after 2-3 layers the stepper motor for the filament stops moving and wont push the filament thru. Im using PLA that came with the printer with heat bed at 60. Now am i suppose to oil it first for the R2 like we did with the R1? What is odd also is when im on octipi and i use the control to extrude its pushes the filament out but wont do it now after a few layers as its printing.
