Description
In the pursuit of a better alternative to the M5 lead screw i saw that acme lead screws have come down in price due to higher demand. After figuring out how to implement this upgrade i came up with this design.
This upgrade requires three printed parts and a structural modification of your printer whichwill force you to recalibrate your printer.
--PLEASE NOTE--
The screws holding the IR probe will come loose over repeated homing of the X axis IF YOU DO NOT LOWER THE X AXIS HOMING SPEED FROM F2000 TO F1000 OR LOWER, the probe does not recognize the end stop quickly enough to avoid a collision with the z axis screw.
Bill of Materials:
437
4 M4x10mm cap
4 M4 t-nut
469
3 M4x10mm cap
3 M3x12mm countersunk
425
2 M3 x 50 cap
2 M3 x n/a countersunk
X end stop
2 M2.5 x 6mm
Printer Brand:
RepRap
Printer:
Ormerod 2 528.4
Rafts:
No
Supports:
No
Resolution:
0.2mm
Infill:
25%
Notes:
I have used meshmixer to reorient the .stl files to rest on the platform the way i printed them.
The parts are printed in transparent PET-G from devil design with no cooling fan.
The 15mm gap
Due to z wobble i feel it necessary to sand the 15mm thick "wedge" in part 437 and 469 to get a similar thickness on both parts. This is measured with a caliper. The gap moves the motor away from the 20x40 extrusion so the spindle of the stepper motor is located on the same plane as the M5 lead screw was in.
