"The road to hell is paved with good intentions." Topic

We changed the nozzle for a smaller one on our FDM printer and did testing then it was time to revert. I have changed nozzles before in the vary rare times it blocked with no problems. But this time I got it wrong, broke wires and then worse cross threaded the nozzle in the heater block. In the end I replaced the entire hot end to do it quickly. The moral of the story, don't mess about when you are tired and just want the job done, that's when you can make costly mistakes. ;-).

Sorry you went through that, thanks for the words of wisdom though. Some life lessons cost more than others unfortunately.

Agreed. At some point you have to say "I have reached my stupid point" and postpone everything requiring thought until you've rested and probably slept.

Every seriously stupid thing I ever did in my career was at the end of a long shift, and generally when I was hungry. That's not even considering the infamous Night Shift Wall, which went on ten feet past where it should have turned.

You know….. now that you phrase it that way (particularly the thread title, and thinking about 3D printing)…

I wonder if anyone has ever done a 'road to hell' model. Flagstone- or cobblestone-type road, with flowers and smiley faces and hearts and whatnot as the tiles, slowly changing to fire and skulls and spikes and such as you get closer to the "hell" end.

The point is not the good intentions, rotscheck: it's that the road to Hell is paved--smooth, easy and downhill all the way. Read Allingham's Tiger in the Smoke some time.

The rest isn't even a road--just bad maps, uncertain declinations and datums, and "they can't expect me to traverse THAT!"

Cross threading will destroy the most complex item in a way far and above the cost of the screw-in item.

Always pays to take one's time.
