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?
Under Quality – Layer Height – First Layer Height. Adjust the layer height as needed. Generally speaking, your first layer should be no less than half the nozzle diameter. So, a .40mm nozzle first layer height should be .20mm. Thought for larger beds, you may wish to increase the first layer height a bit to help with bed adhesion over a wide area.
My first inclination is to got to Quality – Walls and surfaces – Avoid Crossing walls and check that box. See what happens when you print your Benchy.
If you still have issues, go to you filament settings for the filament you are printing with, (the little pencil to the right of the filament box), make sure you have the Advanced slider on, click on the Settings Overrides tab and check the Length, Z-hop height, On surfaces, (select All Surfaces in the drop down box to the right), Retraction speed, (the default is fine), the De-retraction speed, (set to zero), Travel Distance threshold, Retract on layer change, Wipe while retracting, and wipe distance.
This is a start.
