Hi I'm using Marlin 1.1.0 r6. When I send M119 and non of my end stops are activated ..oddly they are showing up as TRIGGERED. However when I actually activate the circuit by hitting the end stop, the end stop lights up and show up as OPEN Now I can move my my x,y,z axis forward but never backward because my min end stops are all TRIGGERED instead of what I guess should be OPEN instead for all my axis to move I'm using makerbot style endstops Thanks https://reprap.org/forum/read.php?406,685696,685696#msg-685696 Mon, 20 Jul 2026 21:54:39 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?406,685696,685700#msg-685700 https://reprap.org/forum/read.php?406,685696,685700#msg-685700
Eg in marlin find

const bool X_MIN_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.
const bool Y_MIN_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.
const bool Z_MIN_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.
const bool X_MAX_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.
const bool Y_MAX_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.
const bool Z_MAX_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.
const bool Z_MIN_PROBE_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.

and what ever you min endstops say, swap it to the reverse

eg const bool X_MIN_ENDSTOP_INVERTING = false;

make it

const bool X_MIN_ENDSTOP_INVERTING = true;

Change each min endstop]]> Dust Prusa i3 and variants Mon, 11 Jul 2016 00:30:53 -0400 https://reprap.org/forum/read.php?406,685696,685696#msg-685696 https://reprap.org/forum/read.php?406,685696,685696#msg-685696
