MIGBOT Z - Endstop limit adjustment

thingiverse

Can easily micro-adjust the height of the nozzle off the bed by turning the adjustment knob one-eighth to one-quarter turn. This is great when changing filaments and resetting the Z offset. After using it a while, you will develop a sense of just how far to turn the adjustment. Move it slightly, then hit "Z Home" and see the results. Print Settings Printer: Migbot i3 Rafts: No Supports: No Resolution: 0.2 Infill: 30 Notes: Lay the "Z-Limit switch adjust adjustment holder" on the back with the nut slots and mounting screw indents up. How I Designed This Reasoning behind build: Always had difficulty adjusting the Z-end stop limit switch. It was hard to get it positioned perfectly, then try and hold it in place while tightening the mounting clamp. The switch moved too easily up and down and all around the 8 mm polished rod. It was too easily bumped out of position. Wanted something that could be easily micro-adjusted, and was repeatable. Parts: (1) 4 inch 6-32 machine screw (4) 6-32 nuts (2) small washers (1) small 3/4 long spring Notes: The first one I made was for a Migbot i3 (manufactured by Electron). Made another later for a HIC-Mendel i3. The HIC-Mendel version needed a slightly different "Spacer Block". The spacer block is necessary to keep the limit switch mounting bracket from spinning around on the 8 mm polished rod. Since it uses the stepper motor mount bolts to hold it in place, you may have to use slightly longer metric bolts there.
