Sienci Limit Switch Holder

thingiverse

Limit or End Stop switch holder for Sienci Mill One. There are two models, one with horizontal and one with vertical adjustments. You may want 2 of each, or 4 of one. You should glue or stick the wires and switch to the holder in some way, I used hot glue. I made this model because taping the switches down wasn't secure so they would move after being bumped, and it did not offset the switches from the wall far enough. Locate the best place for the gantries to hit the button when moved out all the way, drill a hole, and bolt it in. Tape the wires along the enclosure and connect to limit switch pins on CNC Shield. Sized for a 1/4" or 6mm push button tactile switch to stick out just beyond the bolts on the angle stock mount. The bolt hole fits M3. Search Amazon or other source for "6mm 2 pin pcb push button" https://www.tinkercad.com/things/aWEstIAEG35 This is a good tutorial to follow, but you do not need the PCB sections for X and Y if you solder your wires directly to the pushbutton terminals and offset them from the wall. Remember to shrink wrap the connections. https://www.instructables.com/id/Add-Homing-Switches-to-a-Sienci-Mill-One-CNC/
