Question:
1) It looks like two failed attempts? One with a brim and one without?
Just one attempt, two pics included (one a little closer). So this is one single print that went awry. Sorry if that was confusing.
2) Possible that the x-axis belt slipped and offset the hotend?
Not sure. What I've tried this far is tightening the z-frame (meaning the entire U-shaped scaffolding). The crews were not very tight, which may be because this was put together a couple of weeks ago and I've not retightened anything.
3) Possilbe the print came loose from the build plate?
The print stayed on very tightly - and actually, compared to my old printer (an Ender 3 Pro), this takes much longer to release a certain print after finishing. So the adherence to the hot plate is very good, if not a little excessive, frankly.
4) What slicer are you using? What were your settings?
Were you using supports for the bottom? Maybe orienting it standing up with a brim would be better?
I've been using Creality's own slicer, which I'm not in love with - I think it tries to pack more functionality than prior versions, but does that by putting certain settings in odd places and hides others altogether. Very tough to make sense of it, at least for me. Difficult to find are such things as settings for other PLAs (temperatures), or the "rafting" and supports, etc. Not to mention the lackluster wifi functionality, which is inexcusable in 2024. I'm still moving a memory thingie from computer to the printer.
If PruaSlicer, could you run a summary program I wrote (G-Code Viewer) and post a screenshot?
