Y axis endstop always triggered on Maestro
-
So...
No matter what I do M119 always says Y at min stop.
This started happening after upgrading my bed axis.
Endstop is connected as normally closed and set to normally closed in the firmware. I have no G90 in the wrong place, it just happened after the power cycle. I am losing hope quickly.

@Jaco-Conradie If you have a normally closed switch, then when it gets activated it becomes open circuit. So if a wire falls off, or you have a bad crimp or there is some other reason why it is open circuit, then it will act as if the end stop is triggered. If you have a multi meter, check continuity of both wires from the switch back to the board.

Connections are soldered and I replaced the switch with a new one.
What happens is that if I click "HOME Y", Z lifts by 5mm, Y moves about 5mm, Z goes back down and printer thinks it's homed. I can't start printing like this. Is there no way to just remap the endstop input to the extra extruder endstop? Seems kinda silly to me that a board this expensive can't do that. You can do it with the motor drivers very easily, why not the endstops.

Hi Jaco,
this is the way the RRF2 firmware works, your Y end stop must be connected to the Y end stop connector on the board.
In RRF3 you are free to map your endstops to the connecter on the board to your liking...

Or you could move the Y motor to the spare extruder stepper drive (assuming you only have one extruder), and then use the extruder endstop! So in config.g if you currently have:
M584 X0 Y1 Z2 E3 P3
Change to
M584 X0 Y4 Z2 E3 P3
This remaps E1 to the Y axis. If you have a second extruder, you can map this to the Y stepper motor driver:
M584 X0 Y4 Z2 E1:4 P3Ian
