BETA - Piezo z-probe for E3D Titan Aero (mounted direct via motor)

thingiverse

Precision Piezo presents - Titan Aero (or other similar extruder system) Piezo sensor plate. This is a beta, I have one working but I am keen to hear your feedback and see any modification you make. Please share. If you mount your titan aero (or other similar extruder design) direct via the motor screws, then this plate allows you to use piezo z-probing. Print it in PLA, or PETG (ABS will warp as its tall and thin). Drill out the four holes which match a nema 17 motor pattern to 3.2mm. Mount between the motor and x-carriage/print head. Insert a 20mm piezo disc into the top, there is a groove for the solder pads (presuming the use of murata 7bb series 20mm piezo - which are a reliable, known quantity). Tighten the screws holding the motor, enough to ensure the motor and attached hotend is firm, but not super tight or there won't be a little compliance to allow the piezo to function. My test setup has a quite firm nozzle, whilst allowing slight movement when the nozzle touches the bed. Attach to a suitable amplifier circuit such as those available at http://www.precisionpiezo.co.uk Probe away. :) Join the discussion here http://forums.reprap.org/read.php?1,767998,787507,page=19#msg-787507 Youtube https://youtu.be/cPwi2WWcSV4
