Genmitsu 3018 CNC Endstops X, Y, and Z (No drilling into CNC required)

thingiverse

This endstop setup for the 3018 Pro CNC requires the following 6 pieces to be printed: - 1x 3018_endstop_x - 1x 3018_endstop_x (mirrored) (mirror w/ slicer of choice) - 1x 3018_endstop_y_stop - 2x 3018_endstop_y_switch - 1x 3018_endstop_z Both the x and y endstop mounts have internal channels to help with wiring/cable management. The x endstop (3018_endstop_x) will need to be mirrored in your slicer of choice if you want both a left (x-min) and right (x-max) endstop. Mirrored 3018_endstop_x is installed on the right-side (x-max) and the un-mirrored native 3018_endstop_x is installed on the left-side (x-min). The z endstop needs to be installed on the side of the spindle opposite where the x-axis motor is mounted so that it doesn't run into the bolt heads used to mount the motor. **Hardware used**: - [M3 3d-printed t-slot nuts](https://www.thingiverse.com/thing:3050607) - [M3 nut/bolt set](https://amzn.to/3c3Iqba) - [Micro-switches](https://www.ebay.com/itm/164660710238) Resize micro-switch mounting holes with an 1/8" drill bit to accommodate M3 hardware. The following list of console writes in Candle seemed to work to enable homing on the machine, however your mileage may vary. Please use the [Grbl reference](https://github.com/gnea/grbl/wiki/Grbl-v1.1-Configuration) to double-check the settings before proceeding. 1. $5=0 - limit pins are active low 2. $20=1 - enable soft limits 3. $21=1 - enable hard limits 4. $22=1 - enable homing cycle 5. $23=3 - home towards X-, Y-, and Z+ 6. $24=25.000 - homing feed, mm/min 7. $25=100.000 - homing seek, mm/min 8. $26=25 - homing debounce, milliseconds 9. $27=2.000 - homing pull-off, mm 10. $130=285.000 - X Max travel, mm 11. $131=177.000 - Y Max travel, mm 12. $132=41.000 - Z Max travel, mm
