zprobe Activity

recoush

Working on my Zprobe installation (Corexy Large Format)

Plan to use D59 for the probe pin

Noticing with the 12V NPN with internal pull-up Inductive sensor LJ12A3-4-z/bx

The signal (output) is wired to a 12v relay in1 (high/low trigger) The relay Common is wired to ramps VCC 5v and the NO is to signal pin (D59 not wired in)

Noticed:

when the  nozzle is within filament distance the Zprobe tends to trigger due to proximity to the bed (makes sense)

just monitoring the relay is not connected to pull-up D59

Just wondering? (did not find any notes on the forum)

during printing is the ZProbe inactive? (maybe ignored is a better choice )

thanks

There is an option in the configuration for 'only check endstops when homing'

recoush

well then , may  have to use an endstop and not D59 which is Aux2 guess i have to do more research that's why we test :>)

thanks

No, pin number is not relevant as long as you enter it in config.
What MartinH wanted to say is that z probe is always sending signals, but with ALWAYS_CHECK_ENDSTOPS 0 the signal is ignored when not homing or probing to solve the approximation problem.
