No everything is ok, no shorting, or demons or something like that grinning smiley

I use marlin firmware, cura software and ramps board if that helps....

then im thinking maybe a slicing issue with cura. have you tried a G-code from Slic3r or anything?

Let me guess:
The print goes fine for a while, then you see some unwanted movement and either with that movement or right after the extruder goes nuts?
If that is the case I would suspect comnnunication problems.
Baud rate not high enough or not matching firmware settings, USB cable too long, too many other USB devices in use....

Can you attach the same exact GCODE file that causes the problem when printed? We would like to rule out the slicer as the error.

My machine has done this twice for two reasons, First time was a failing stepper driver, second time was a loose connection in the wiring.
