ERCF dual filament toolhead sensor for filametrix system

[tawdry gulch]

Where does the wiring for the 2 toolhead sensors go? Do they go to the ERCF board?

I put mine going to the main printer/octopus board.
I had a non-CANbus breakout board that had extra pins I wasn't using

They go to any empty ground (no positive pins) and sensor ports on your printer controller boards. Mine went to the xy endstop pins on my nitehawk board.

I've used the two unpopulated gpio on the nitehawk since I'm not using sensorless homing. They are labeled FS and SU. I soldered 3 wire to a jst PH header for the two sensor and ground and soldered the matching jst on the sensor so everything is easily disabled. The 2 switch share a common ground. Remember to pull up the gpio if you end up using these.

have u seen the replies above? do they solve your question?

[tawdry gulch]

I believe so. If I understood correctly I should be able to connect them to the MMB board on the ERCF. This thing is going to be a nightmare to configure. Much larger of a project than I initially expected.

for ercf we have #ercf_questions im sure u will get better help there compared to here, which is just for V2 printers 🙂

if u feel like u are good to either alone or in the channel i linked u, feel free to add the "solved" tag to this post so people know
