Is this normal?
Recently had a power outage while printing, resumed a few hours later and left serious line issues. Seems to have “missing lines” or just not quite center to the original print. Chalked that up to well I’m lucky to still have my dragon. Just may have some minor issues.
Then recently had a filament issue where the AMS couldn’t pull back the material. Happened 6 hours before I woke up……So I got up and fixed it this morning and it started printing again……
It now has line issues.
Should I be expecting this anytime the printer sits for a few hours and has to resume?
Is there a setting I need to change to fix this?
If I sanded, filled and painted it I could hide it but that’s not applicable to everything I print.
Yep. Power outages in particular seem to cause layer shifts. Resumption seems to have enough issues that it doesn’t really work if it’s a model you want to look good.
If you have lots of power outages you might want to consider a UPS or just not print at risky times if you do have risky times.
There’s a few threads about this here already you might want to check out with discussions of backup power if that is of interest.

This occurs on both my A1, and my Ender 3 V3 SE’s.
I try not to pause for large amounts of time if I can avoid it. Even sometimes brief pauses (to insert a weight/object) give very minor artifacts on that line, so sometimes I just try to yeet the coin in while the extruder is partly out of the way.
If I may ramble for a moment: In some ways, the Ender’s speed control (1-255% in increments of 1%) work better for these kind of hacks than the bambu (50%-166% in 4 increments) because you can just slow it down to 10% for a brief moment and not have to incur the stop travel / restart without the ability to home again (cuz theres a model on the plate that would get crashed into if it home’d, just kinda the nature of a build plate system)
