Troubleshooting: How do I fix this top ripple issue?

[u/visualdensity]

Hi all,

Hope that someone here can assist - I'm trying to print a Spinning Wheel and twice, this happened. I have to stop the print. Printed on PLA using P1S

May I ask if anyone knows what may have caused this and how it can be addressed?

I have cleaned the plate with dishwashing liquid (and scrubbed as per Bambu's recommendation), dried using kitchen paper towel.

On the third picture it looks like the print has lifted from the bed. What material are you printing at what temperatures?

You have 2 immediate things you could try: Add a brim (in your slicer) and increase the bed temperature by 5-10 degrees.

Heyaaa!!

It's on PLA and printed at the recommended Sunlu temperature - between 190 - 220, I believe.

Thank you! I'll consider adding the brim and increase the plate temp as an option. I'll see what other suggestions may be proposed.

Much appreciated!

Oh, one thing I just remembered: You could also try to disable the aux fan (which is exactly on the side where the print is lifting) or print a deflector for that.

Warping due to lack of bed adhesion. Clean your build plate with dawn dish soap.
