Help with Homing (2 replies)

Seems like this should be pretty simple once everything else is working but I have another question about homing the axis, watched a lot of vidoes of people showing it working but not how it was calibrated and the documentation I've read is not clear to me.

I move the Y axis all the way to the front, esentially Y bed is all the way back, X all the way to the left and Z all the way down a paper's width above the bed. My question is when I have it at that point do I just connect to pronterface and click the "Home All" button? Do I put the axis all the way to where the end stops are tripped when I cick home all or shuld they be just before triggering the end stops?

Also does anythign need to be done to save the settings or will pronterface reconnect where it left off last?

Thanks,
Marc
