QuadFusion MGN12 PrecisionPiezo Andromeda Mount

thingiverse

This is a reworked version of my previous MGN12 Quadfusion mount. I've swapped out the BLTouch probe for a Piezo probe, giving me a new way to detect when the print nozzle makes contact with the bed. To make this work, you'll need to add a third stand off to the QuadFusion - the screw hole is already there. When the nozzle touches the bed, it triggers the piezo. Note that I originally included a screw between the Andromeda Piezo and the standoff, but later removed it since just having the standoff push the piezo was enough to trigger it. Here's what you'll need: * Universal Piezo-Z Probe PCB V2 (for 1-2-3 or more piezos): https://www.precisionpiezo.co.uk/product-page/universal-piezo-z-probe-pcb-v2-x-for-1-2-3-or-more-piezos * Andromeda: https://www.precisionpiezo.co.uk/product-page/andromeda To set this up, make the following changes to your Duet Maestro firmware config: In Config.g: M558 P1 I0 H10 R0.4 F1200 T2500; Set Piezo Settings and Z probe type/mode 1 G31 X0 Y0 Z-0.10 P800; Set Z probe trigger value, offset, and trigger height Be careful when setting the trigger point - as with any Z-probe configuration, you can damage your print bed if not done properly.
