CNC3018PRO Endswitch mounts

Simple holders for end switches to use with 2020 aluminum extrusions . Only one screw fixes the holder to the aluminum profile, for the switch I used M2x10mm hex head screws.

hardware u need:
6x M2X10
2x M5x10 with t-nut
1x M6x10 with nut
2x M3x10

I also added settings for the GRBL witch work for me. I will also ad a fix for the board witch worked for me, if somebody has any limiting switch related problems...
