Mini Mill End Stops

thingiverse

These 3 parts serve as mounts for Makerbot mechanical endstops (or compatible clones) to a Harbor Freight (Sieg X2 class) mini mill. The Z axis bolts to the screw hole on the top of the column. The Y axis bolts to my Y axis (printed) conversion here: https://www.thingiverse.com/thing:2591938 . The X axis is mounted to the dovetail by removing the handle end of the mill and sliding it onto the dovetail. This does reduce your X travel by 20mm. These were not intended to be permenant, but something you could print up in an hour and get going. Ultimately I plan on replacing all the printed parts on my mill with metallic parts and when I do I'll optomize limit switch locations to maximize travel. On a related-yet-unrelated note if you notice flaky behavior or have some confounding, nondeterministic behavior it is likely because you have RFI issues. Your stepper cables are likely not shielded. For me I was able to get homing to work, no problem, but trying to enable hard limits was an exercise in futility.
