End stops don't work...

Hello all

I have some serious problems with end stops on my makergear prusa mendel.. Please note that I am currently only working on the X axis to dial that in before I start with the other axis... I am using Marlin firmware cause I want to use SD card later

Please see my code in configuration.h

If I set

const bool X_MIN_ENDSTOP_INVERTING = true;

to false on both MIN and MAX or just one of them the printer just bounce in the wrong direction and stops, but if I set them to true; the printer moves in the right direction but don't stop when it hits the enstop...

Can you see anything that needs chaning here? I am having the printer oriented the way that the Y axis motor is away from me, and the endstop for the X axis on the right side...

I wouldn't worry about moving the carriage yet, just hit the switch with your finger.

Make sure the endstop is working correctly
You can issue M119 through your host software to get the status
It will tell you if it's either open or triggered

It should report triggered when pressed, and open when not
depending on the type of switch you have, you may have to change the following line for it to be right

const bool X_MIN_ENDSTOP_INVERTING = true;

From what you're saying, setting false is probably correct

I'd change this line:

#define X_HOME_DIR 1

to:

#define X_HOME_DIR -1

Also ensure it moves towards the endstop when you tell it to Home X
If it does not, you might do one of 2 things.

Change this line
#define INVERT_X_DIR false //denne e OK
to true

Or flip the connector for that motor around.
