Thanks for the advice, I'll give this a try. So far I've been working around the issue by lowering the nozzle and then raising it once the outlines are complete.

<p>I switched over to a new filament recently (Sunlu PLA) and I can't get the first layer details to stick properly without squishing the first layer way too much.

What type of print bed do you have? Glass, BuildTak, PEI? Printer model might also be helpful. Please update the question by [edit].

Stringing on first layer unless I squish it

# Stringing on first layer unless I squish it

(Asked by: username_0 on 2021-08-17)

I switched over to a new filament recently (Sunlu PLA) and I can't get the first layer details to stick properly without squishing the first layer way too much. Prints don't always fail, but little circles and the initial skirt rarely stick as they should. The issue appears to be that when it starts to extrude at a new location, it's not always close enough or extruding fast enough for the initial filament to stick and it gets lifted on the next pass. Other things stick just fine, it's just at these transitions where things lift a little. My bed is level and in general things are printing just fine. It's just the start/end of initial layers that tend to have problems and lift just enough to cause problems later.

If I lower my nozzle enough, I can get it to stick more reliably but then I have other problems because the first layer is so squished that the ridges rise and cause problems later.

I've read dozens of articles and tried all these things already:

* Dried my filament
* Adjusted my Z-offset (BLTouch)
* Attempted to recalibrate my retraction settings
* Replaced my nozzle, cleaned the hotend, and replaced the Bowden tube.
* Tried different temperature settings
* Cleaned the bed
* Calibrated my E-steps and played around with flow rates further

It used to print fine, so I guess it could just be the filament but I'm hoping there's something I can still do. I'm using an Ender 3 v2 with a BLTouch, new springs, replaced Bowden tube and red metal extruder. Printing at 210 °C with 60 °C bed.
