Ormerod z axis upgrade

thingiverse

In my quest for a superior alternative to the M5 lead screw, I discovered that Acme lead screws have decreased in price due to increased demand. After figuring out how to implement this upgrade, I came up with this innovative design. This upgrade necessitates three printed components and a structural modification of your printer, which will require you to recalibrate your printer. --PLEASE NOTE-- The screws holding the IR probe may become loose over repeated homing of the X axis if you fail to decrease the X axis homing speed from F2000 to F1000 or lower. If this occurs, the probe may not recognize the end stop in time to avoid a collision with the Z axis screw. Bill of Materials: 437 4 M4x10mm cap screws 4 M4 t-nuts 469 3 M4x10mm cap screws 3 M3x12mm countersinks 425 2 M3 x 50 cap screws 2 M3 n/a countersinks X end stop switch 2 M2.5 x 6mm screws Print Settings: Printer Brand: RepRap Printer Model: Ormerod 2 528.4 Rafts: No Supports: No Resolution: 0.2mm Infill: 25% Notes: I have utilized Meshmixer to reorient the .stl files so that they rest on the platform in the manner I printed them. The parts are printed from Devil Design transparent PET-G with no cooling fan. Post-Printing: The 15mm gap Due to Z wobble, I believe it is essential to sand the 15mm thick "wedge" in part 437 and 469 to achieve a similar thickness on both components. This measurement was taken using a caliper. The gap relocates the motor away from the 20x40 extrusion, positioning the stepper motor spindle on the same plane as the original M5 lead screw was located.
