V6 Nozzle Mount Probe - Delta Pro / Atom 3 Lite

thingiverse

Information ======= Replacement z probe for the Monoprice Delta Pro and/or Atom 3 Lite, though this will work for any printer that has a V6 style nozzle. Instructions ======= Print at low layer height and I'd suggest turning off retractions to avoid blobing in small areas. Since this fits over your nozzle and the microswitch has tight tolerances, it is better to clean up some stringing than have blobs all over or under extrusion. Once printed test fit over nozzle. If this fits your microswitch will likely fit. You'll need to heat up your hotend and clean off any residual plastic before fitting. Let cool before testing fit or you'll melt the printer part... Cut your wire length in half, solder to your microswitch legs in your desired configuration(NC/NO). I'd suggest NC. With a NC configuration if you accidentally probe while the microswitch is not connected it will stop at the 'safe probe height' and never tough the bed, because it thinks the probe is always triggered. Apply heatshrink. insert your wire leads through the hole in the side escape hole on the printed part(not the nozzle hole). Press Microswitch in place so that the plunger is directly below the nozzle. Insert your 2x M2x10mm screws. Notice one is screwed in from each side. Strip and crimp your dupont connector. Configure your printer firmware and test before actually probing.
