Z axis not stopping at Endstop
-
My z axis keeps going through the min endstop and going into the bed.
Here is my Homez

G91 ; relative mode
G1 S1 Z-250 F300 ; move Z towards the switch until it triggers
G1 Z5 F100 S2 ; move Z back 5mm
G1 S1 Z-10 F100 ; move Z slowly towards the switch until it triggers
G90 ; back to absolute mode

what type of end stop is it ?? a switch, piezo probe \ bltouch ? have you tried manually 'switching' the end stop ?
-
its a switch and i have tried manually pressing it when the printer was lowering while it was homing but it still didn't do anything.
-
Does the light on the Duet board light up or turn off when the switch is clicked?
-
@phaedrux it lights up
-
Is this a new setup or did it just stop working recently?
Can you post your config.g so we can see how the endstop is configured?
What kind of switch is it?
-
@phaedrux here are the switches Gowoops 5 PCS of Mechanical Endstop Switch with Cable for 3D Printer Makerbot Prusa Mendel RepRap CNC Arduino Mega 2560 1280.
the setup is new and i have not printed anything yet.

@puppet172 said in Z axis not stopping at Endstop:
; Endstops
M574 X2 Y1 S1 ; Set active low endstops
M574 Z0 S1Where you have that, try this:
M574 X2 Y1 Z1 S0That's assuming you have the X end stop at the high end of travel and the Y and Z end stop at the low end of travel. S0 sets them to active low switches which should work with those makerbot switches.
