Until recently I have had very few failed prints that were not user error. A small issue with trying to print the HSW panels but thanks to the communities help I got that solved. The last four days I have had 3x the errors then all previous put together. It seems I am having adhesion issues to the PEI plate. It has been washed with Dawn and cleaned with 99% IPA. Sometimes these errors have been caught by the machine, on two occasions I only received an error when the head was knocked off and over 10 have been continued until I found the error visually. I have calibrated the machine numerous times. This morning I had a Z axis error that was caused by a chunk of PLA back and above the waste chute but I have since cleared and recalibrated the machine and my next print was also a failure. I am running the bed temp at 65 the nozzle at 220 and the filament is dry (AMS running at 16% humidity) The ambient temp has been between 60-75 degrees. Errors have occurred with multiple filaments and it seems the larger the print the more likely the failure. I will open a ticket with Bambu but the last time I did that it took 9 days to get a response so I’m not very hopeful. Any help would be appreciated. Please see attached pictures.
Have you tried another plate? Cold plate etc, or even flipping the one you have now. Also switch the AUX fan off as it seems to be that side lifting first. Sometimes its environmental, temperature in the room can add issues.
Super hot water, Dawn dish soap and a scrub sponge. Go to town 
If that doesn’t work a light rub with some real fine grit sand paper will help rough up the surface.
I will try the other plate and see what happens, I’ll also mark this one and try the other side. Good idea on the fan. Temp has been fairly stable 65-75
I scrubbed the you know what out of it with dawn and then dried and then hit with IPA. What grit on the sandpaper? I have 220 to 2000
1000 grit is what I have that came with other replacement pei build plates. I’ve used it on my oldest bambu plate with great results. I just lay the sheet out on a table and lay the build plate on it and slide it a few times.
I’m pretty sure prusa recommends a cleaning with acetone every once in awhile to help “reactivate” the pei so to speak.
Have you tried a factory reset?
I have not, I have updated the firmware and run full self test and calibration
as an update, I turned off the fan for the first 5 layers, total failure which didnt trip any sensors, all the filament ripped right off of the plate, I may try bumping up the temp slightly on the nozzle
I also flipped the plate, same result
bump up your plate temp 5-10 degrees
Honestly, try it without the IPA. I’ve stopped using it. Dawn and hot water for the win. Steel wool to refresh a textured plate is easier than sandpaper.
@RRubrig Bugger… Ok, have you tried the scouring pad or sandpaper (which is one recommendation on the Wiki) The Bambu Lab Textured PEI Plate troubleshooting guide | Bambu Lab Wiki
Will do that in the morning
Side note. Tried a very noncomplicated print with the cold plate, worked fine. I need the PEI to work to match the finish on a few panels, will try to refresh in the morning, surprised it would need to be after only two months of using it.
up to 75 on the PEI?
65c should be ok for stable prints, unless you have an inaccurate temp sensor (not unheard of). An IR temp gun would be ideal about now I run 65/55c on my high temp smooth plate, and 55 on my PEI most days.
Knowing the cold plate worked, I’d be inclined to persist with troubleshooting the PEI for sure (as the nozzle/filament/etc isn’t a huge factor now).
Sorry, didn’t notice you were already running it warmer. I run mine at 60 for when there are small parts on the textured. I’d lean towards a real good rough scrub cleaning of that plate or a few rubs with some sandpaper. Always helps me to get things sticking on the textured plate after a lot of prints. The cold plate working makes me really think its just a plate issue like GenericUser said.
I have had this same issue for several days now specifically with the Textured PEI build Plate. After trying to trouble shoot this further and even rolling back the firmware, I decided to try the cool plate and Glue again and found it would successfully print. Verified my settings and sliced again after a calibration and still would not print on the Textured Pei Plate. It was almost like the Z height was off for some reason but only with that plate.
Now this evening I decided to calibrate once again and see if I could return to normal printing, During the calibration process it dug the nozzle into my build plate effectively ruining it. Ive decided to open a ticket for this issue.
If you are using a brand of filament other than Bambu or filament labled high speed then slow down your print speeds
A decent work around is under your speed setting set slower layers to a minimum of 10
But if your filament can not keep up with the speeds you will get a plethora of issues such as nozzle drag over the infill, artifacts on the outer walls, or even a nozzle clog
Slow down 
If the same filament had not worked on the same plate for over 100 prints I would go with this but I am not thinking it is the issue, I’ve also tried it with 2 other filaments and both have had failures. Going to try a large flat print on the cold plate and scrub the heck out of the pei plate and see what happens
Is the black pla the only one doing this and what type of pla pro or basic ?
Try setting the ( initial layer height ) to 0.25 set the ( initial layer speed ) both to 40 mm/s this way we can see what happens and tune from this point.
60c textured pei bed plate and aux fan off for next test.
Your z offset should already be -0.04 in the start G-code unless you changed it ?
