I've just had one of those "D'oh!" moments...

I decided that I wanted to make a small object in nice yellow PLA, so I grabbed the reel and mounted it on my CoreXY printer (my goto printer for most jobs). Set up the model - and it just wouldn't print. The first layer kept getting unstuck from the bed, no matter what I did with it (cleaned it, resprayed with hairspray, and so on), After wasting a ridiculous amount of time I decided to give up with the CoreXY (which can be fussy sometimes) and dragged out my slow-but-reliable Prusa clone. Still had problems with the first layers, but eventually managed to finish the print - which was a mess, with splitting layers and generally looking scruffy.

Sat and scratched my head for a while, then thought "splitting layers... not sticking to the bed..." - yep, I'd picked up a reel of yellow ABS instead of PLA as intended.

That was a couple of hours wasted... sigh...

I once forgot the buildplate and didn’t notice it until i had recalibrated the height to print on the magnetic base

Now if I had a day so good that I had only wasted a couple of hours I would regard it as a really good day. Come to think of it, if I had a week so good that I had only wasted a couple of days -- or a month so good that .....
Still, I guess that is 3D printing!!!
