Underbed piezo holder for z-probe

thingiverse

<h1>Description</h1> This is my piezo disc holder, designed to function as a z probe. I have successfully mounted it on an Anycubic I3 MEGA printer. Fortunately, I was able to reuse the leveling screw and springs from the original setup. The more you tighten the screws, the better this holder performs. During Auto Bed Leveling (ABL) procedures, it's essential to decrease both z and y acceleration. When set at 500mm/s^2, this system works flawlessly. To ensure optimal performance, I recommend heating the nozzle to 130°C if there is still plastic residue on the tip. The small tail attached can be used to clip two-pin Dupont sockets and fasten cables with cable ties. Update: On November 24th, 2018, aproemel created a modified version of the UpperFrame specifically designed for printers with thicker y-carriage systems. <h1>You need</h1> - Four Drilled 27mm Murata7BB Piezo discs (I source mine from precisionpiezo.co.uk) - Four M3x40 DIN7991 or longer screws to connect the heated bed - Sixteen M3x16 DIN912 + nuts or longer to close the frames - A hole in the y-carriage for the fourth screw... or simply secure it with three screws - One hundred millimeter cable ties - The necessary electronics for the piezos <h1>Assembly</h1> - Place the "stamper" within the lower frame, ensuring the chamfer faces towards the piezo room. - Install the piezo disc in the mid frame, positioning the crystal to face into the piezo room. - Align the wires so they face towards the holder. - Secure the nuts in the upper frame. - Stack the frames together (lower, mid, and upper), ensuring the nuts in the upper frame face outward. - Insert three screws on the exterior. Do not tighten them yet. - ... Complete the electronics setup ... - Slide the stack over the carriage edge until the hole aligns. - Attach the printbed using the springs. - Tighten the screws. - Tighten the printbed screw and roughly level the bed. <h1>Stuff</h1> Remixes and modifications are encouraged.
