Underbed Piezo Mounts

thingiverse

Mounts for 27mm piezo sensors under the bed for Z homing and auto bed leveling Things to bear in mind: * There is a drilling jig to help with drilling the holes for the piezo holders. Use a 2.5mm drill and tap the holes for 3mm screws * This will reduce usable Z by about 10mm * As most piezo driver boards have three or fewer piezo inputs, at least two piezos will need to be wired in parallel * The underside of the bed MUST be thermally insulated to prevent a change in the piezo response characteristics * Print the piezo holders at 0.05mm layer height. Four are required. * Print the arms at 0.1mm layer height. They should be printed upside down with support to ensure the lugs that actuate the piezos are smooth. Two of the arms a required and two of the mirror arms are required * Everything else can be printed at 0.2mm
