With the 14.12 and 14.12.1 firmware my UM2 freezes without showing an error. The display goes blank and printing stops. This always happens when the custom gcode of the 'pause at z' plugin is reached. I tweaked this plugin so it drops the nozzle temp before going into pause. So I don't know for sure whether it's the temp drop (M104 S40) or the pause (M0) that causes this. I reverted back to 14.09, works flawless.
