I'm in the process of fitting my v-core 3.1 with an ERCF and I tried to get a toolhead sensor going, and after making one with a Hall effect sensor I realized that it's pretty bad and unreliable.
So I made my own version for the EVA 3 platform based on a well known design approach of using a ball bearing and a switch.
Required Parts:
- 1 x JST XH 3-pin male connector (not a must but makes for an easier wiring)
- 1 x Omron - Micro Switch (same one as the ERCF endstop)
- 2 x M2x8 Screws (its actually a bit less than 8mm so you might need to file the end a bit)
- 1 x 4mm ball bearing.
