I have been using my P1S for almost two years, and I have always had a perfect first layer. However, over the last two weeks, I noticed that my first layers have started to show problems.
I performed a full maintenance routine: I cleaned everything, lubricated the Z screws, recalibrated the printer, and printed a single-layer test sheet, but the problem persisted. I also tried a new smooth PEI plate, and the results were exactly the same.
I assumed it might be a nozzle clog, so I performed a cold pull, but that did not help.
I then performed a manual bed tramming, recalibrated again, and printed another single-layer test sheet, but the problem remained unchanged.
I have been using Bambu Basic PLA for several months without any issues, and these problems only started appearing in the last two weeks.
I’m running out of ideas and hope that someone can help.
Thanks in advance.
Before diving too deep into troubleshooting, I’d start with the obvious, especially if the printer has already been in use for two years.
First, have you replaced the nozzle at any point? It may simply be worn out by now, which can lead to a variety of print quality issues.
Second, check the extruder gear as well. The teeth can wear down over time, reducing grip on the filament and causing under-extrusion or inconsistent extrusion.
Before spending hours troubleshooting, it’s worth ruling out these basic wear-and-tear items first.
Thank you.
I will try to replace the nozzle, i didn’t suspect of the nozzle or the extruder because the only defect i am detecting at the moment, is the first layer.
