A couple times recently I’ve left the A1 printing overnight on a simple project, and come back to find the plate has pulled itself off the unit and there is a spaghetti mess in it’s place.
This morning it was still attempting to print even with the plate partially off, and it gouged the left side of the plate pretty thoroughly in one spot. The majority of the items are still stuck firmly in place, one did come off. These are only about 2mm thick (keychain charms) that I’ve printed hundreds of times before, it’s not the file doing anything odd.
I don’t notice a difference between this one and the Bambu plates as far as magnetic strength, but if that’s the reason, is there not a failsafe to stop the printing? It basically went all night attempting to make something while scraping the plate and printing in the air lol.
It detects a build plate at initial of print. If its absent or badly placed it will report an error and won’t start to print. Definitly there is no protection in mid print.
I have one more idea: what type of infill did you used? Default grid infill cause some problems with nozzle scratching on it. You can counter it by changing infill type to gyroid or turning on a z-hop in the slicer. I prefer not to use grid infill.
Ahhh that’s the issue! I have 9 standardized files for these little keychains in different designs, and this ONE file wasn’t changed off the default grid infill and monotonic bottom surface, both of which have caused that nozzle scratching and plate issue before. Good callout.
I guess I thought it had more detection beyond at the start, good to know. I may also turn try using the zhop, now that you mention it. Thanks a ton!
