Scared to rewire endstops, help me pick new ones?
-
@buurman yes, basically. although RRF only monitors endstops during a certain move type, theres still a change for EMC to cause false triggers of the endstops.
This is even more of an issue on the artillery printers that use ribbons. They are notorious for having false triggers etc especially when the wagster mod is used to add a bltouch -
@jay_s_uk yeah mine has the extra pins on the extruder board BLT so that should not be an issue. I could just run a cable up to the y endstop (thats the only one that goes through the ribbon).
Should be okay like that, right? Because i think i still have some new mech end switches laying around

@buurman give it a go and see if you get any trouble

There is a video out there showing that microswitches are actually very, very good when it comes to repeatability.
They are simple, safe and if you don't use the plain kind (not circuit board) they only need 2 wires. If you go the route be sure to the the COM and NC connections.
The kind with the circuit board have a couple of advantages (usually). They provide an LED to verify state. The signal is actively pulled-down or pulled-up so the signal wire to the Duet is never dealing with an open circuit which can act like an antenna pickup up noise.
There may be kinds a circuit board that don't behave that way but all the ones I have used do.
