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 don’t know much about Gcod, yet!
I should never respond before coffee in the morning.
did you change anything firmware or wires since it worked?
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
that looks correct,
probe is hooked to the correct pins on z-min?
(https://docs.v1engineering.com/electronics/dual-endstops/)
of course 
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.
didn’t mean to edit my previous post. Does M119 say triggered with disconnected probe wires?
then it should be something in the firmware
I have an Archim board on my MPCNC… so I’m not much more help.
this thread is similar, Z probe not stopping Z axis
maybe #define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN should get commented out?
I’ve tried everything what was said in the thread but i doesn’t work. I’ve managed with the that thread to shut the z-max off.
I’ve double checked my wires with a multimeter. so that also not the problem
It may be broken hardware.
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.
How can I be sure that hardware is broken? Before I spend €200 to order a new rambo1.4.
The firmware in MarlinBuilder releases has been tested with a jumper. If yours isn’t working, it is hard to believe it could be anything but hardware.
The rambos are generally very tough. I have not seen a case of the endstops being broken. So it is worth trying the simplest test possible.
That’s dissapointed i thought when i order everything by v1 then it will be oke
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.
it was indeed a hardware problem. Uncle Ali did help me too bad that the orginial rambo was not available.
