Hi i’m new here from the Netherlands. I’ve got a lowrider 2.
I’ve got a rambo 1.4 and everything is connected with the firmware dual endstop LR. My probe did function 1 week ago. But now it says with M119, triggered. I’ve tried to unplug everything and plug a endstop in to it but is still says triggered. Please help me!.
i’ve tried to change it. but then i’ve tried to change the code back and then upload it again. That didn’t work. So i’ve unzipped the file again and then again i’ve upload it. the only change that i’ve made in that file is de bedsize.
what does this block of configuration.h look like?
// Mechanical endstop with COM to ground and NC to Signal uses “false” here (most common setup). #define X_MIN_ENDSTOP_INVERTING false // Set to true to invert the logic of the endstop. #define Y_MIN_ENDSTOP_INVERTING false // Set to true to invert the logic of the endstop. #define Z_MIN_ENDSTOP_INVERTING true // Set to true to invert the logic of the endstop. #define X_MAX_ENDSTOP_INVERTING false // Set to true to invert the logic of the endstop. #define Y_MAX_ENDSTOP_INVERTING false // Set to true to invert the logic of the endstop. #define Z_MAX_ENDSTOP_INVERTING false // Set to true to invert the logic of the endstop. #define Z_MIN_PROBE_ENDSTOP_INVERTING true // Set to true to invert the logic of the probe.
It’s like:
**// Mechanical endstop with COM to ground and NC to Signal uses “false” here (most common setup). #define X_MIN_ENDSTOP_INVERTING false #define Y_MIN_ENDSTOP_INVERTING false #define Z_MIN_ENDSTOP_INVERTING true #define X_MAX_ENDSTOP_INVERTING false #define Y_MAX_ENDSTOP_INVERTING false #define Z_MAX_ENDSTOP_INVERTING false #define Z_MIN_PROBE_ENDSTOP_INVERTING true
it’s always says triggered. I’ve unplugged it i’ve changed the wires. I’ve made a closed loop with the wires. I’ve opened the wires. it always says triggered even when there is no wire in it.
I test the software on my desk by using a jumper between S and - pins. That should show open in M119. There are no wires or switches that can go wrong. The only thing is, I have to be disciplined to only change it when the power is off. If I ever jumper + to something, it will release the magic smoke.
If your testing determines that the pin is not working (which is very rare), then it is possible to reassign the endstop to another pin and therefore salvage your Rambo board.
