Hi.
I have a P1S, that I’ve had for a few months now. I’m not new to FDM printing, but new to Bambu.
Steadily, over the time I’ve had it, I seem to have had poor bed adhesion of some kind with increasing regularity - whether that’s whole prints coming loose, or warping and curling at the extremities.
I mainly print with Bambu PLA, but have also been trying PETG-HF lately. This is on the Bambu PEI smooth plate, textured plate, and now the Supertack plate.
I’ve tried cleaning the plates with washing up liquid (what I assume is what Americas call “dish soap”?) and isopropyl alcohol. If anything this made things worse.
The latest print I’ve tried, I knew was going to be a challenge. It has a fairly small initial footprint. I’m using a brand new roll of PETG-HF, dried at 65degC on a brand new Supertack plate. All stock Bambu settings. I added a brim to give it a fighting chance of adhesion. However, when putting down the first layer, this is what I see…
(hopefully you will too, and I’ve uploaded the photo correctly)
Now, to me, there appears to be a definite gap between the walls of the object and the brim. This pretty much renders the brim useless, right?
My instinct is that the first layer isn’t getting “squished” enough - as in the bed is too far from the nozzle on the first layer. What do you think? This would potentially explain why things aren’t adhering well.
Or perhaps it’s something else? Underextrusion? Worn nozzle? (although it has only had a handful of PLA prints through it, and one of PLA wood)
I’d be interested in how someone with more expertise than me would tackle this. Calibration? As I say, I’m running everything with out-of-the-box settings, which worked great initially.
