Endstop bracket for 3KU Delta Printer

thingiverse

The arms of the default microswitches of the 3KU delta printer have a annoying habbit of bending. When this happens the printer needs to be calibrated again, also with each bend of the arms the arm gets a little weaker and the accuracy deteriorates. This endstop brackets are designed to replace the default brackets and allow the microswitches to be used without the arms. With this the accuracy is higher and the system is a little tougher. Also becouse the microswitches are now on the outside part of the printer the chance that the bowden tube or any other cable hits the microswitch is a lot smaller. Extra parts needed: 3x M3 screw 16mm 3x M3 nut Endstop cables (the default cables are a little to short) 3x microswitch (if you want to keep the original microswitches) Tools needed: Drill + 3.2mm drill bit Print Settings Printer: 3KU delta Rafts: Doesn't Matter Supports: No Resolution: 0.2mm Infill: 40% Post-Printing Mounting Slide the bracket over the printer plate and drill a 3.2mm hole trough the top hole trough the printer plate, make sure you drill straight. Mount the (new) microswitch onto the top of the plate, make sure the switching part points to the outside. Put a M3 nut into the nuttrap Slide the bracket over the printer plate and use a M3 screw to fasten the bracket onto the printer. Connect the microswitch cable to the RAMPS board. Make sure the timing belts don't rub against the switch and first test by hand that the switches work (you can use M119 to see which endstop triggers)
