Weird print failure at 85% point - looks like extruder left/right position shifted significantly to the right
I have a fairly simple design that I wanted to print tilted upwards 60 deg for a stronger part. The first print went fine, but subsequent prints failed at about 85% with a significant rightward shift. I checked for any physical impingements on the bed and/or extruder travel, but everything seems fine. I looked at the gcode with the Prusa gcode viewer, and it looks OK too.
Anyone have an idea about what I'm doing wrong here (.3mf, .bgcode, good/bad photos and a short video attached)?
TIA,
Frank
RE: Weird print failure at 85% point - looks like extruder left/right position shifted significantly to the right
Could be an optical illusion, but it looks in the 2nd picture like the part pulled up some off the bed compared to the 1st. If that happened it's likely the tool head crashed causing the later shift.
Are you cleaning the bed with isopropyl alcohol between prints?
I'm seeing the bright white line around the base on the first picture looks perfectly straight, while in the 2nd it isn't.

Hmm, you could be right - I'll try that again with better base support and see what happens. And yes, I'm keeping the bed clean. I don't clean it between every print - only when there are clear adhesion issues 😉
