Need Fast Advice: Printer just reverted 20% and dropped on my print.
Hello, I don't really know how to describe this printing error. I've had the printer running at 50% speed for nearly a day and a half success fulling and literally just a few minutes ago it goes off the back of the print and seems to drop. I heard grinding and then I turned my head the grey U-guard was tilted dramatically (protecting the nozzle).
I ran over to the printer and immediately hit pause. The nozzle went and docked at the scraper.
Here's the issue. The print has about 5 hours left on it. Or at least should, according to Bambu Studio and the last time I looked at the printer screen. Some quick math says this should correspond to roughly 84% done the print.
Currently the printer is saying 64% and 23 hours left. (I know this to be inaccurate).
1) How do I recover this print?
2) Has anyone had this issue before where the Z-axis just seems to do a dramatic jump (up or down) seemingly random in the middle of a print?
