27mm Piezo mount for Re-X Carriage by rkrammes

Last crawled date: 3 years, 1 month ago

I would rotate it -90 degrees and print with supports under the "wings" that you use to mount it to the carriage. The way this requires the plastic to flex I think it would be best printed in something like PETG, ABS, or some kind of Nylon. I would not recommend PLA. The relevant features are a .5mm slot for the 27mm drilled piezo with a 1.5mm x 5mm slot for the wires and solder points. I put a tiny .1mm rim around the innermost hole to concentrate pressure on the ceramic disc. There is a 2.25mm space for the raised portion of the stepper to fit into. Again this is totally untested and I will update things if/when I am able to get it functioning. I am also planning to modify the top cover to contain the V2 Universal PCB but first things first. In the picture, I highlighted the piezo in blue.
*update 4/25. I updated the .stl to give more clearance for the wires and solder points since I had to put on new leads. I also covered the back of the piezo with electrical tape and put some shrink rap on the stepper shaft to insulate everything. The shaft fit through the hole without modification but with the shrink wrap I had to expand it a little. I havn't gotten to firmware yet but I've got it triggering by tapping the hotend. I made a video but I'm not going to upload it to youtube just for this. Allow video uploads thingiverse!
*update 4/26. It works!
*update 4/27. I added a mount to the top cover to hold the Universal PCB v2.x. It has cutouts for the LEDs and adjustment screws. Wiring can be a bit tight in there so make sure you clean it up to avoid interference issues. Requires 2 M3x8mm bolts with nuts. There can be a clearance problem if the bolts you used for the wire harness mount are too long. You can either use shorter bolts or back out the one to the right a bit.
