Rostock Penholder - Proximity Sensor - Modeled for Geeetech

thingiverse

Update: My new hotends are longer than the original ones, requiring an extension to the mount for the proximity sensor to function properly. I can upload a simple schematic to use a 12-volt source on a 5-volt binary input. If you lack a programmable board, ensure that your auto leveling system utilizes either an NPN or PNP circuit, depending on whether your NC or NO contact triggers correctly. Print Settings Rafts: No specific requirement is necessary; raft printing is supported. Resolution: Layer resolution stands at .2 mm per layer. Infill: The default infill percentage is set to 25%. Notes: Leave the part print configuration unchanged for optimal results. Consider attempting an upside-down print without protrusions, but be aware that the lack of surface area may cause adherence issues. Good luck with your printing endeavors; enjoy! How I Designed This Using FreeCAD My dissatisfaction with Geeetech's initial design stemmed from its unreliable auto leveling probe performance, prompting me to create a custom replacement. The new design ensures the LJ-12A3-4-Z/BX proximity sensor is secure and doesn't bind against the rods. Expect a photo upload soon, showcasing the completed part in action. This creation has undergone successful printing tests, functioning precisely as intended.
