End-Stops won't stop motors from turning
May 15, 2016 10:25PM
I am kind of new to marlin and 3d printing. I have been tinkering here and there with it but I cannot figure out what is wrong. I have a mini kossel 3d printer. I have endstops on the top of the x, y, and z axis to make homing easier at the top. The problem I am having is when i press home, it moves up but once it reaches the endstops, the lights trigger but they fail to stop all 3 motors from spinning making a horrible noise and i am always forced to unplug from the power source. I have included a snapshot of the part of firmware i think is relevant and a picture of my 3d printer set up. Please help! Also, when i send the m119 command it says,

SENDING:M119
Reporting endstop status
x_max: open
y_max: open
z_min: TRIGGERED
z_max: open

use m119 a bit more

First when no end stops are being pressed
Then then the X max is being pressed by hand
then when the Y max is being pressed by hand
and finally when the Z max is being pressed by hand

Each should change from open to TRIGGERED when you press them

Make sure the correct one gets triggered also, or it will stop the wrong motor and that gets really confusing.

If it doesn't change, check your wireing and firmware motherboard setting
If its a ramps make sure your endstops are plugged into the max endstops positions
