Overhang and update 01.07.02.00 problem

Hello, I have some problems and i dont know how to fix them. First thing is about new update to 01.07.02.00. After update i had some problems with infill, outer wall, spaghetti fails, not completed prints (bambu says it is completed) like some of this photos. This two things are printed similar before and after update. Strength fail everytime in same moment.
The second problem is: When i printing round overhang that everytime do this in same position. I tried change setting. I tried do automatic and then manual calibration too. I tried print it on A1 and its was printed normally but on x1c not. whats wrong? can somebody help me please?



Is tha aux fan on? I would turn it off or down to 20% or so if it is.

I taste from 100% aux fan take down to 50% and 20% but its same or worse. Its everytime next to the seam. Its not important if is seam stright or curved or random it makes every time line after the seam.

i have no problem its not the update

have same issue and it appears after last firmware update. Now when I trying to downgrade firmware it showing me same problem as in newest version. I never had any problem with my printer and prints like now.

God thanks…I am sorry about your problems but is a small consolation for me I am not alone. Thats mean we are not totaly useless. Can somebody realy help please? =)

This is happening to me too, on my Mini and regular A1. I found there are overhangs which otherwise should’ve printed perfectly, yet were awful. Slowing down helped a bit, but the issue persists.

I’m staying on 01.07.01.00 until I actually encounter one of the issues the release is supposed to fix. Why can’t they fix the flow calibration settings disappearing after a power cycle?

Cleaned and lubricated srews , cleaned carbon rods, belts tensioned, calibrated and this is result. Yesterday it was better then after maintenance

Ok, finally we found a solution to our problems… After repeatedly tensioning the belts, I tried a factory reset on printer. After calibration is everything ok.
