MPSM Z-Axis expansions

thingiverse

The text appears to be a set of instructions for modifying a 3D printer to install a Z-axis limit switch bracket. The modifications involve removing various parts, installing new standoffs and screws, reassembling the printer, and adjusting the slicer settings. Here's a breakdown of the steps: 1. Remove side panels, connectors, and bottom panel. 2. Remove screws holding tower to base, and pull off tower. 3. Remove screws holding tower panels on top and bottom, and set aside. 4. Decouple Z threaded rod from X-gantry or remove it altogether. 5. Install main standoffs into screw holes used for attaching tower to gantry, and install 10mm standoffs for motor (not needed for 25mm kit). 6. Mount Z limit switch bracket to new standoffs, and slide bracket onto motor standoffs or motor screws for 25mm kit. 7. Install lock washers and nuts on standoffs if desired. 8. For 35mm kit only: install motor spacer over standoffs. 9. Reinstall motor and front cover. 10. Feed cables through tower hole and reattach with screws. 11. Level bed as normal, and adjust slicer settings for new Z size. The instructions also mention a few caveats: * If the X gantry is raised all the way up, the printer may time out before reaching the switch when homing. * If a print starts without properly homing the Z axis, it may start in mid-air. Overall, these instructions seem to be specific to a particular type of 3D printer and may not apply to other models. It's also worth noting that modifying a printer can void its warranty and may require additional expertise or tools.
