Mk2S - 2.5S Y-axis motor and idler mounts for Mk3 aluminum frame

prusaprinters

Have you upgraded your Prusa Mk2s - 2.5s to a Mk3 type frame with aluminum extrusions? If so, you will have noticed that the MK3 Y-axis motor mount is opposite of a Mk2s and has no limit switch. You could modify the wiring so that the Y axis stepper runs backwards but the limit switch would still be missing. This set has two different Mk 3 Y-axis motor mounts reversed to accommodate the MK2s series and has a limit switch mount grafted on. One is extended, one not. I currently use the short version. The limit switch works correctly against the standard Mk2s series Y carriage. It is intended for the Mk3 type aluminum extrusion frame upgrade. At the other end, the Y axis idler must be moved down slightly so that the belt will clear the Mk2s Y carriage belt mount. Two sizes are provided, "B" and "C", with "C" being lower. These mounts are intended for use with 5mm bore idlers, as I feel that the standard 3mm bore idlers have too much wobble. Note: The .stl files did not export correctly, so it is best to use the .3mf. The .stl files are included for reference only.
