Underbed Piezo Mounts

thingiverse

Mounts for 27mm piezo sensors underneath the bed enable Z homing and auto bed leveling capabilities. Considerations to keep in mind: * A drilling jig is available to facilitate hole drilling for piezo holders, requiring a 2.5mm drill and tapping holes for 3mm screws. * This setup reduces usable Z by approximately 10mm. * Since most piezo driver boards have three or fewer piezo inputs, at least two piezos must be connected in parallel. * The underside of the bed demands thermal insulation to prevent a change in piezo response characteristics. * Print four piezo holders at 0.05mm layer height. * Print two arms and two mirror arms at 0.1mm layer height, ensuring the lugs actuating the piezos are smooth. * Everything else can be printed at 0.2mm layer height.
