Help wanted. Calibrating issue on i3 build. Using Repetier. None of the axes are homing. What could be wrong? Pl. help.

Inverted end stops?

I don’t know if when I click the Repetier Home icon for say Y axis, it supposed to seek the end stop. That is what I want it to do though.

When I send M119, I get xyz min -open and xyz max triggered.

It sounds like your firmware has some conflicting settings regarding whether they are activated when open or closed, or perhaps things are trying to move in the wrong direction. I’m not familiar with Repetier, but it may not be configured to home to xyz min.

Is the printer at xyz max when like M119 says, or somewhere in the middle?

Somewhere in the middle.

Well, if it’s reporting xyz max stop are triggered when it’s not at xyz max, then something is wrong with end stop configuration in the firmware. If you don’t have max ends stops, make sure they’re disabled. Make sure the end stops are correctly set to expect the switch to be open or closed when the machine is at the stop. Make sure travel directions are correct, so that min travel is at the min end stop.

I will check. Thank you so much.

Yep. Bang on.
#define X_HOME_DIR -1
#define Y_HOME_DIR -1
#define Z_HOME_DIR -1

This was all at default 0 instead of -1
Thanks
