3D Printing Rule 0

This is the most important rule for anyone with a 3D printer.

Never start to think of your 3D printer as an appliance.

My printer has been behaving very well of late. So well that I’ve started thinking it is something I can switch on and it will just work. Silly me. This morning I started a print and it promptly embedded the print head in the bed - necessitating a bunch of re-alignment and fiddling to get it back working again. Lesson learned.
