Prints keep failing. (lemmy.world)

I have been using my Bambu A1 mini for the last several months without major issue, but suddenly I can't get anything to print. Even a benchy detaches before finishing.

I have scrubbed the plate with a fresh sponge, soap and water. I kept my filament in a dehydrator for a couple of days, then immediately tried to print.

There is a local problem, where an illegal landfill caught fire, and it can't be put out. I smell burning rubber all the time. Could that be the cause of the print failure? What else can I do?

Lower the Z offset. Not by too much, or it'll scratch the bed.

"Everything is failing" is not useful info at all. Post a video of the failure happening if you don't know how to describe it.

Maxwell asked if it was all prints failing it just the benchy. OP replied "everything is failing".

Ok, I am having trouble uploading the video. Anyway, all of the prints will be fine up to a point, then detach. The nozzle is colliding with the models. In some cases, I can see the model being pushed down on one side or other by the nozzle before it detaches.

Yeah, if the nozzle is hitting the part, then it's very likely a cooling issue. If an steep overhang isn't cooled properly, it'll curl upwards.

Either you're printing too hot, or the fan is too slow or failing. For PLA, you can leave the fan at 100% after the first or second layer, and print between 195 and 205°C. Printing too fast also means the fan may struggle with the amount of hot plastic.

Can you paste your slicer settings?
