I tried cleaning the build plate to discard bed adhesion issues and re running the bed level every time y start a print and the problem persist. As the photo shows looks like the flow is not consistent along the build plate only on one part of the plate with a correct first layer. Can anyone help me solve this issue or had the same problem?

Welcome to the community.

Well, the good news is that this is not a build plate adhesion issue. That would show blotches. Instead, this looks like a under extruded filament profile. Try two things, Calibrate the filament and/or increase the flow ratio.

This is what dirty build plate first layer test looks like. These fingerprints were deliberate in order to show the affect of a dirty plate.

Thanks for the quick response. What’s killing me is that in some parts the layer formed well with good material bonding between lines. I Will try to increase the flow ratio to check one of your tips but perhaps on the ok part now i Will have over extrusion.

New update. I performed flow calibration and PA calibration. It improved but i am still having problems with the edges of the plate.

That looks like a bed leveling issue. I recommend doing a full vibration calibration to be sure—it takes about 20 minutes. A factory reset might also help, but keep in mind that you’ll have to go through the “Bambu-Shuffle” :crazy_face: to reconnect your printer. If you have experience any network connectivity issues in the past, save that as a last resort. You know how unstable the connection can be once it’s broken, so proceed carefully.
