Sienci Longmill Mods

thingiverse

If you're looking to add endstops to your new LongMill, here are the parts I came up with. First, the Y-axis mounts on the inside of the y-axis gantry mount, using the two bolts that hold the delrin nut. I removed one bolt at a time, taking care not to strip the threads. Next, the X-axis mounts on the top left side of the x gantry. To secure it in place, I used a small (3.7mm) threaded insert to tighten the endstop against the plate. You could remix and scale down that hole and probably get by without using an insert. Lastly, the laser mount is a remixed version from Andy and Chris's Onshape catalog, designed specifically to fit the mounting holes of the laser diode I built myself.
