Dear gr5 thanks for your reply,
When the printer shuts down it jumps straight to the boot screen. In my experience, the machine usually shuts down when the M302 code isn't inserted in the starting G code. Although I have to say, I have seen it moving the XY axis but not extruding as well. Maybe I'm jumping to conclusions to fast and is it a power related issue. It didn't seem like a power issue because when I was printing with higher temperatures it didn't happen. Is it possible to check the power brick?
