Limit Switch: Available at http://sirichaielectric.com/limit-switch-V-156-1A5-Omron-product 2. M3 x 15mm Bolts 3. 2 M3 Hex Nuts 4. 2 M4 x 10mm Bolts 5. 2 M4 T Nuts Adjustments: To get the microswitch to click at Y=220, it will work seamlessly with Cura right out of the box. However, I still recommend modifying your End G-code to wait for the hot end to cool down. The custom post-print G-code that works with Cura, Prusa Slicer, and Slic3r is: G4 ; Wait M220 S100 ; Reset Speed factor override percentage to default (100%) M221 S100 ; Reset Extrude factor override percentage to default (100%) G91 ; Set coordinates to relative G1 F1800 E-7 ; Retract filament 3 mm to prevent oozing G1 F3000 Z20 ; Move Z Axis up 20 mm for free filament ooze G90 ; Set coordinates to absolute M109 R40; Wait for the hotend to cool down to 40C G1 X0 Y{machine_depth} F1000 ; Move Heat Bed to the front for easy print removal M84 ; Disable stepper motors M117 Finish..
