Promega Triple Z Axis modification
Description
Modification to replace the original Z axis design with a triple leadscrew design, allowing auto tramming and true auto compensation. This is an involved modification that requires good workmanship and accuracy if you want to gain all the advantages of a triple leadscrew design Z axis. See the PDF for detailed instructions. This requires a well tuned printer. There are images showing the best part orientation for printing. Everything prints without support, except where noted below. Print the following with 1mm walls and 20% infill in the material of your choice: 2 - FrontRailTemplate 2 - 15x15to12Template 1 - StepperMountTemplate 1 - RearStepperMountTemplate Print the following with 2.5mm walls and 70% infill in PETG, ABS, PETG with carbon fiber. PRINT the Platform_Mounts with support (both versions): 2 - Z_Platform_Mount 1 - Z_Platform_Mount_Rear NOTE: I have removed the bearing mounts from the assembly, these cause more issues then they solve - so they're gone. Print the following with 2mm walls and 20% infill in your material of choice: 4 - Foot If you're using an optical endstop for the Z axis, print the following with 1.5mm walls, 20% infill, with support: 1 - Z Axis Optical Stop Housing 1 - Z Axis Optical Flag Good Luck! Let me know if it makes your printer better. I'll try to help you through tough spots - but I do have a day job, so help may be delayed sometimes. Regards.
