Can't move any axis back due to triggered endstops

Can't move any axis back due to triggered endstops
July 10, 2016 11:27PM
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

You need to invert your endstop in firmware, what m119 says is whats important

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
