Power plug- can't unplug

Recommended Posts

I've got an Ultimaker 2 Extended.

I'm attempting to unplug the machine from the back. The user manual says that all I should need to do is slide the collar outwards and the plug should come out with ease.

Mine doesn't.

I've pulled the collar away from the machine, pushed it towards the machine, twisted it a little left and right- I can't find a position where it'll free the connector, and moderate force won't detent the connector. Is there some special trick that is missing from the description in the manual? Last thing I want to do is break it off the board.

The plug should be inserted with the flat part upwards. If you are standing behind the printer, grab that part that slides towards you and pull in that direction while holding the printer with the other hand.


Sorry for the weird camera angle. I can't access my printer easily from the back...

If you did not used glue (Joke) it is normal, it feels sometimes like tooth extraction because of the wall from printer pressing a Little against plug. You can remove it without causing any Problems.
