I am currently attempting to print something detailed and I am using a stock P1S with Bambu PLA Basic, on the default “Extra Fine” settings (with automatic tree supports enabled, and 4 wall loops).
Any idea how I can fix this issue? The outside of the print is also slightly ‘wavey’ in spots (no visible pattern as to why some areas are wavey and others are not).
To clarify regarding moisture. My printer is in a room with a 24/7 dehumidifier that keeps moisture below 35%, and the filament is sitting in a filament* dryer 24/7.
Im wondering if you have a partial nozzle clog or a piece of filament in the extruder gears. My first guess would have been wet filament though.
What is a moisture dryer? A box with some silica, or something with an actual heat source.
If you haven’t dried the filament properly with heat, then it is most likely not dry. Silica won’t make wet filament dry, it will only keep already dry filament dry.
It is an actual heat source with air circulation inside.
Doesn’t matter what it is, it doesn’t look like it’s doing the job.
Other possibility - you’re extruding waaaay too hot.
Is it a Sunlu dryer box? Those dont actually exhaust the air, they just recalculate the moist air.
Yes. I have been opening it to vent with a small airflow. It should be fine.
I am trying a temperature test print right now to see if I can dial in the setting.
I haven’t fixed it, nor have I changed any settings. I just started using Gyroid infill pattern (when your filament is slightly globy likely due to some incorrect extrusion settings, the overlap with grid causes the print to dislodge). I am still in the process of trying to optimize my calibration. Not done with that yet.
Did you do some basic work prior printing? Like a temp tower or flow calibration?
You should do this with every new filament you are using on your printer.
then you can see if it’s a temperature problem or a flow problem or if the two things are not affecting the prints maybe it’s something else. Then you become more clear of further steps. And it’s better for the forum helpers to help with the problem
I did some calibration and it toned down the issue. It’s at about 5-10% of what it was. I also switched to gyroid to prevent collision of the print head and the piece that grid infill has.
Although I haven’t completely eliminated the issue, I’ll say it’s good enough.
But thank you everyone for the responses!
