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
This is a huge problem for me with high model, Any infill like aligned or rectangular where there is crossover is a huge problem for me when the model gets high. The rough surfaces cause the model to sway and knock over. I have tried to increase the heat, this still doesn’t help though.
The only thing i’ve found that helps is concentric, but this is not a good solution because of the strength for me.
has anyone logged an issue regards this? Is it really the firmware or does the speed just need to be reduced?
Have you tried unchecking reduce infill retraction in others tab?
I started having this problem today with a design that had no problem printing before. Using Inland PLA+ on p1S printer. Problem occurs with green but goes away with white PLA+. Tried slowing infill speed to 50% but did not fix green issue. Tried drying for 4 hrs and new sealed spool, neither helped.
I had that, changed a few settings and it was ok, but the problem randomly appeared and stopped production for 3 days while I did diagnostics…
That was not as irritating as having all my custom configs for filament get set to all print at 190 for everything, not sure how that happened but I am awefully glad I am so anal about backups…
I have tried every solution that I could find here and on the general web (reddit, etc.) I finally solved the problem once and for all. Now, I always print my important prints on my flsun T1. I like my A1 more ( by a lot) but, sometimes you just have to “do what you gotta’ do” to get things done while saving on filament costs.
Just encounter this and it’s because of grid infil crossing over itself on the same layer height, change to gyroid or rectilinear infil pattern.
