I have tried various infill patterns, such as gyroid, etc. I always use flow calibration and have a profile for my different filament types. It is Azure PLA that I use, in various colors… It’s always a new spool, as 915 grams are used for this model!.
What you are seeing here is the model warping off of the plate and creating the irregularity in the top surface. Try thoroughly cleaning your plate with dish soap and hot water and adding a brim to keep the edges of the model secured to the plate.
The top of the skull likely needs a support, right up the middle, like the ‘moon globe’ might.
That or you can do variable layer height, a setting in bambu studio that allows you to set a more granular layer height at the top there so there isnt so much overhang.
Just to throw another thought into the ring…
I’m now seeing similar issues on my P1S printing models that I have been printing for months, using filament that I have standardised on (PolyLite PLA Pro) and with the filament dried before use from an AMS with good desiccant and a hygrometer reading around 20%.
I had printed some ABS GF for a while, so I swapped the nozzle incase it was the problem and recalibrated the machine… it wasn’t.
I tried all the usual things with no success until I went back to previous firmware, and ran the calibration again, and all is okay. I’m now running 01.05.02.00 firmware and slicing in BB Studio 1.9.7.52.
Tomorrow, I will reinstall the latest firmware and try again to see if the problem returns.
I get this intermittently, almost all due to warping when printing multiple parts. Changing seams to “Nearest” helped to not knock parts loose when travelling and let the print recover if possible. Quality will be impacted but that might not be a huge concern if the print finishes well.
How did it go? I’ve got the same problems OP showed in their video. I’m on a X1C.
I had same issue, slowing print down during fill process worked. I have a Panda Touch, I just changed speed to SILENT and problem disappeared. Thanks for the tip.
Hi, I just slowed my prints down during infill, this overcame the nozzle continually hitting previous infill layer
