I'm deliberately letting the current spool run out, gonna happen in about an hour.

After the runout sensor is triggered, there's going to be about ten inches still sticking out of the print head/extruder. It's a Creality Ender 3 V3 KE, in case that matters.

Anyone successfully recovered from filament runout? That interface layer can't be adhering to the lower layer properly, can it?

I have run out of filament and come home hours later and changed rolls and resumed my print and I've never had an issue with it. I even printed some silly stands for the chicken baby's water and food to elevate them and I ran out of filament twice and burned up 3 partial rolls getting it done. Three different colors. No issues

It sucks and it's not worth the trouble. If it's a print based on aesthetics, there's a noticeable line. If it's a functional print, your restart may be offset or you might not get good adhesion. Edit: I've also had prints stutter when the option is turned on, then the printer works perfect when I went ahead and turned the option off.

Yes, you can recover from filament runout. Often, there will be a noticable seam. You won't have much of a bonding issue, as the top of the dispersed filement is usually cooled anyway.

Just treat it like a nomal roll change. You won't get a prime though, so push the new filment through the nozzle and break off the cool end sticking out of the nozzle before you press resume.

You won't believe me, but I never had a roll change in hundreds of hours printing. Always avoided it like the plague. Good hint about the manual priming, thanks!

Doing this for science.

The new spool is going to be a freshly opened PAHT one. Let's see how dry it really is, fresh out of the pack.

I burn up nearly empty rolls on silly little projects with no aesthetic value. It's always the same material but often different colors and sometimes there are time gaps between changing the roll, I've never had an issue.
