Underbed Piezo Mounts by fcollingwood

Last crawled date: 3 years, 1 month ago

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
