Deltaprintr KS Piezo Bed leveling

thingiverse

After waging a multi-year battle with the bed leveling Force Sense resistors on my Deltaprintr KS, I decided to give Piezoing it a shot. The FSRs had worked well, but unfortunately, the second one gave out on me. Rather than replacing it from a spare, I'm thinking it's high time for a change of pace. So far, I haven't quite finished this project yet, but I'm hopeful that in the next few days I'll finally wrap it up. The parts are printed at 0.1mm layers with 100% infill. I'm using 27mm Piezo disks, and they're really delivering. The PiezoBase part has support that makes contact with the build plate. If you don't feel like building your own electronics from scratch, be sure to check out PrecisionPiezo.co.uk - he's done an outstanding job! You can find the files to edit here: Tinkercad.com/things/1Rzp7yWNVPR-deltaprintrpiezo. As soon as I get this up and running, I'll post the circuits and more pictures for all to see. EDIT: This project is still in progress. I've made a few tweaks - I added a mod to the top part that includes a pushbutton, and removed the unused version of the top. Another EDIT: It's working great now! Now it's time to clean up the mess and post the circuit I used. Also, I need to add a non-slip surface to the pushbutton because the acrylic disk base keeps sliding around on the PLA. EDIT: I've added some felt pads to the buttons for extra grip. And just to give it an extra boost of stability, I'm placing a concrete paver under the printer.
