Underbed piezo holder for z-probe

thingiverse

<h1>Description</h1> The is my piezo disc holder to use as a z probe. I have mounted it on a Anycubic I3 MEGA. And I was able to reuse the leveling screw and the springs. The more you tighten the screws the better it behaves. During ABL you have to decrease z and y acceleration. At 500mm/s^2 it works flawlessly. I recommend to heat the nozzle to 130°C in case you have still plastic on the tip. The small tail can be used to clip 2 pin dupont sockets and to fasten the cables with cable ties. Update: 2018-11-24: aproemel has made a modified version of the UpperFrame for those printers with a thicker y-carriage. <h1>You need</h1> - 4 Drilled 27mm Murata7BB Piezo (I use the ones from precisionpiezo.co.uk) - 4 M3x40 DIN7991 or longer to connect the heated bed - 16 M3x16 DIN912 + nuts or longer to close the frames - a hole in the y-carriage for the fourth hole... or just screw it with 3 screws - 100mm cable ties - the electronics for the piezos <h1>Assembly</h1> - Put the "stamper" in the lower frame. The chamfer should face in the piezo room. - Put the piezo in the mid frame. The crystal should face in the piezo room. - The wires have to face in the direction of the holder. - Press the nuts in the upper frame. - Stack lower, mid and upper frame together. The nuts in the upper frame have to face outward. - Put in the three screws on the "outside". Don't tighten them yet. - ... do the electronics stuff ... - Push the stack over you carriage edge till the hole match. - Mount you printbed with you springs. - Tighten the screws. - Tighten the printbed screw and level you bed roughly. <h1>Stuff</h1> Makes and remixes are welcome.
