Need help changing the bed home to 0,0,0 and making the printer remember where it was
Hey guys I got another question for ya. I set limits as to how far my printer head can travel like this:
// Travel limits after homing
#define X_MAX_POS 100
#define X_MIN_POS -100
#define Y_MAX_POS 100
#define Y_MIN_POS -100
#define Z_MAX_POS 185
#define Z_MIN_POS 0
This doesn't allow it to go past the bed perimeters when I manually control the movement which is great, however, when I press home the head will go to the right (x+) and slam into the side past my limits.
Any fixes for that?
Another problem I'm having is every time I turn off my printer after a print, the printer forgets that it moved and makes the new location its new starting point. (the lcd says 0,0,0, even though its at say: 17,7,12)
Any fixes for this? thanks!

You need to tell it where the homing switches are in configuration.h. Without that it has no idea where it is when it is powered on.
