I'm having this problem as well.
My printer is a Max Micron dual head prusa i3 clone, which I've heavily upgraded.
At random times the print head will suddenly travel to the X or Y limit, and then return to the print area and continue printing.
Sometimes, even worse, is it will do it in Z!
Imagine being 3/4 of the way through a print and then the hot nozzle suddenly tries to go straight down. CRASH!
For now I've gotten around it by printing via USB/Repetier.
I've re-flashed the firmware with one sent from the manufacturer, but no change.
It's very frustrating because of how random and intermittent it is. I'm very interested in the RCBugFix Marlin but I have no idea about how to implement that.
Do I just copy my configuration.h file into it? I've no idea.
Hope someone can help.
