Probe header



  • What are the four probe header pins for? I'm using David's dIR probe. Do I use Z_PROBE_IN or Z_PROBE_MOD for the signal line?



  • Z_PROBE_IN the _MOD is for the modulated type that where supplied by RepRapPro on the Ormerod and is supplied for Compatability with those probes.

    I set mine up finally yesterday and hope to do some serious testing later today once I get work finished

    Currently the Probe connector is only for sensors that can produce an analog output, such as my IR sensor. As Doug says, ignore the MOD pin. Other sorts of Z probe should use the E0 endstop connector and probe type 4 in the M558 command in config.g.

    I plan to add probe type 5 which would be a probe with a digital output but connected to the Probe connector instead of E0 endstop.
