64mm 3xPiezo Magnetic Effector

thingiverse

I've transformed into a Chimera and I'm now selling this for £13+PP. The package includes two printed parts with the piezo fitted, the cooling pipe, four M3 bolts, and one M3 nut. If you're interested, send me a message here or on Facebook at https://www.facebook.com/messages/t/makinbug. UPDATE 01 Sept '17: I've added a fan shroud and modified part B so its legs touch part A. This makes the hot end more stable when cornering at high speeds. Leadinglights, Moriquendi, (http://forums.reprap.org/read.php?1,635075,page=1), DjDemonD, and others have worked hard to develop a bed leveling probe that's arguably the lightest and most precise available as of June '17. Here are some ways you can use a piezo as a nozzle z-probe: https://www.thingiverse.com/thing:2069480, https://www.thingiverse.com/thing:2319993, and https://www.thingiverse.com/thing:2117069. This is a remix of Idris's (Moriquendi) effector at https://www.duet3d.com/forum/thread.php?pid=10329#p10329. I liked his idea because it offsets the nozzle and doesn't reduce printing height. It works with 3x 15mm piezo disc z-probe, Huntley's magnetic arms spaced at 64mm (other mag arms will work), and Berd-Air cooling. Also see 64mm Magnetic Carriages here https://www.thingiverse.com/thing:2371707. To assemble this, you'll need: 1x Piezo probe board (PM Moriquendi on the RepRap or Duet3d forums) or make your own at https://www.dropbox.com/sh/3q38ew98kt7f8sq/AAB_uA6tQL2ETlGcnfdijm2Ra?dl=0 3x 15mm piezo discs (search Murata 15mm piezo), each with an M3 brass nut soldered to the back 1x M3x15mm bolt 3x M3x35mm bolts 1x M3 nut 6x M3 Nylon Nuts for the spheres This should print without supports, but be cautious when sliding the piezo in place. Use a soldering iron to melt the plastic if you need to make some room for them. I've placed a dab of E6000 where the wires are soldered to ensure they stay put. Part A, the triangle, should face the z tower with the Berd-Air hole. Part B should be mounted with the fan facing the z tower, and all wires should also face the z tower. If part B is printed accurately, the 35mm bolts should rotate freely and not exit more than 1.8 mm down. To set up this configuration, read DjDemonD's post at https://www.duet3d.com/forum/thread.php?pid=7726#p7726 or here https://www.thingiverse.com/thing:2069480. I would add the following: -on my Duet digital mode doesn't work; only analog with VR1 at 11 and VR2 at 4 o'clock -I probe on .8mm PEI, bull clipped to the top of a 6mm al bed, at 210c hotend and 65c bed. I've tested the hotend at 220c for 3 seconds, leaving no marks on the PEI. Caution: probing on PEI glued with 3M 468MP to aluminum plate gives high inconsistencies. I guess this is because 468MP is 0.125mm thick and gives a bit under pressure. In the future, I would use 3m 467MP, which at just 0.05mm, should make for a harder surface. -I've got a -0.15 z offset in my config file and the trigger value is 500 (G31 X0 Y0 Z-0.15 P500). Any questions, please contact me. Enjoy!
