MPMD endstop spacer

thingiverse

This endstop spacer will help you place the Monoprice Mini Delta Printer's endstops at an identical position.\r\n\r\nUse the same endstop spacer for all 3 towers to avoid inconsistencies, which is what using this item aims to prevent.\r\n\r\nIf your printer is too far misaligned and can't print, try using a micro SD card adapter or a full-sized SD card as a spacer to align it well enough to print this.\r\n\r\nYou should probably rotate this so it lies flat on the bed with the prongs pointing upwards. Sorry for not doing that in the design.\r\n\r\n1. Loosen the endstop screws and slide them down.\r\n2. Insert this against the rods with the prongs at the bottom, pointing towards the outside of the printer, and push it up as far as it will go.\r\n3. Slide the endstop switch up as far as it will go, but make sure it remains below the spacer.\r\n4. Tighten the endstop screws without moving the endstop down.\r\n5. Repeat for all towers using the same endstop spacer.\r\n\r\nIn step 3, there seemed to be a gap when I checked with my untrimmed fingernails, but it might have been just my imagination, and I chose to ignore it. It slid up as far as it would go.\r\n\r\nYou may also want to clear your endstop offsets (M666) and save the changes (M500). Check your slicer's starting G-code to ensure you don't have M666 there anymore. You might also need to adjust your Z offset so that your bed squish is correct for your first layer.\r\n\r\nYou may still need to calibrate M666 even after using this due to the delta printer's requirement of extremely tight tolerances, which this printer seems to lack.
