Z-Probe issues

rocketman051894

Hello all,

I am having some issues with getting my z probe to work. I am using it as the Zmin endstop and that works fine. But when I go to probe, it moves around and doesn't actually probe. Then it stops responding. I checked the endstops to see if any were activated and they were not. Also I got correct readings from the G31 command with the endstop. Below is my z-probing conf in my Configuration.h file:

// #################### Z-Probing #####################

#define FEATURE_Z_PROBE 1

#define Z_PROBE_BED_DISTANCE 5

Thank you

You have set Z_PROBE_WAIT_BEFORE_TEST which means you have to hit z probe to start it. That is for the case you have a switch that you place manually below the extruder. Set this to 0.

I having the same issue. I am using a FSR (force sensor) attached to the extruder for the Z-Min Endstop and the Z-probe. How should I have this configured for the Endstop and for the Z-probe?

I've tried Z-min as Switch on Ground, Normally open (wired to S and - on my RUMBA board) and it works fine as an end stop but not as a probe. I've tried Electronic, Normally Open (not sure what Electronic means but I assume that it means that it enables the pull-up resistor and pulls the signal to 5V) and it seems to work for a bit but then there is hysteresis in the signal; it appears to be OFF but when I make Z- moves it stops short as if the End Stop had been triggered, same goes for the Z-probe.

I'm not sure if I have the settings wrong or if I have it connected wrong, but I presume that I want the End Stop configured for Electronic, Normally Open and the Z-probe pull-up enabled as well. Am I correct?

That worked! Thank you very much!
