Higher motor end for Rostock Mini Pro

thingiverse

The stock motor ends for the Rostock Mini Pro lack a few millimetres if you decide to add a display adapter to the RAMPS print and want to keep it tucked away below the printer. These motor ends are 8mm higher than the originals. Instructions The motor sits roughly in the middle, so it is being moved up by 4mm, whereas you get 8mm less total height and 8mm shorter belt length if you keep the rod ends flush with the printed parts (assuming they were before). You can adjust by either 1) cutting the belts to the new length (they should be around 8mm shorter than before, but check each belt individually before cutting), and adjust the print height by 8mm, or 2) Lifting the rods 4mm up in the new bottom part, or lift the top ends 4mm higher up, keeping the belt length and losing 4mm total print height, or 3) replacing belt and rods with new ones that are 8mm longer, keeping total print height and leaving you with enough parts to consider starting to build another printer. :-) Adjust the height in firmware or EEPROM if it has changed, and perform a calibration in any case, simply because you never know if a fraction of a millimetre difference in one of the towers will cause a large change in nozzle height.
