This has happened to me about 5 times now over the past couple weeks. As far as I can figure out it is pretty much a design flaw.
My H2C works perfectly if I load a filament and start a print.
However, as in my last case, using only 1 filament spool, I printed the first print which I loaded the filament, printed fine. The print has 4 plates, almost identical, requiring the same filament which is already loaded. So now, simply resliced the 2nd plate and print.
The filament which was already retracted from the first print is still loaded and begins to feed to the H2C, Error occurs at this point as the filament fails to load. Error message indicates a blocked extruder and says a broken piece might be lodged in the extruder.
SIDE/ADDITIONAL PROBLEM: At this point if you try to reheat the nozzle, advance the extruder, move the print head, or unload the filament and the printer does not respond to the commands, so you can manually fix anything.
After fooling around trying to clear it at the extruder a few times, without success or cooperation (side comment), I manually pull the filament back out, use my cutters, cut an angle on the bitter end of the filament and reload the filament. Then the printer magically works and the error is bypassed.
The reason I say this is a design issue is Bambu recommends the filament be cut at an angle when loading it. Yet the cutting head cuts the filament from the previous job at a 90-degree angle causing this error when it calls upon a previously loaded filament.
Anyone have a solution for either of these issues? Sorry for being long wanted but wanted to be clear.
