At the weekend I cleaned my Mr Beam II and unscrewed the bottom plate.
I discovered that there are two little round magnets in the boarders of the bottom plate but couldn't see an obvious reason for that.
My only reasonable guess would be that these two little magnets give contact to something inside the frame of Mr Beam preventing that one is able to do a laser job without the bottom plate being reattached to the frame.
Has anyone seen those magnets, too.
What are they for?
