Hi,

Been printing for over 12mths now and haven’t turned the unit off for more than 2 weeks total in this time.  
I have converted it to run 1.75mm filament with new hot end tube and printed parts also.  
Been working hassle free for ages but now it will only heat to around 170° to 200° then cuts out to a reboot screen.  
The ABS filament i use runs a nozzle temp of 270° and bed of 110° all day overyday.

Any help would be appreciated.

Ok so self fixed the issue,  
When i had it apart cleaning it i screwed the heat sink too close to the hot end causing them to fight each other giving me the low temp code for resetting the unit.  
Unscrewed them woth 5mm gap and all good now
