Printer blobs

Bambu Lab P1 Series Troubleshooting
1

New ps1 purchased over black friday. Out of the box did flawless prints. With about 175 hours its starting to get messy. Lines and blobs/defects like seen in the picture.

The picture is of layer one/two of a thin round circle used to support esun card board filament holders. The 2 round holes are suppose to be there but the lines and blobs are not.

My guess is: the plate is contaminated with oil, especially the oil comes from your body. Just like how finger print left at crime scene.

First thing you can try is to clean the plate with soap/dishwasher and hot water, like 60-70°C hot. Scrub the plate violently with scotch-brite.

I will give that a try thanks.

Be careful though because you definitely don’t want any scratches on your print plate.
