Over the past 2-3 weeks I’ve been having failure after failure where prints are lifting up.
This is happening with;
Both PLA and PETG
Using generic, Bambu, or previously working calibrated filament profiles.
.2 and .4 nozzles
PEI and Cooltack sheets
Cleaned plates with dish soap
Dried both types of filaments
Any combo of door and lid open/closed.
Updating 6/16
Slowing down first layer
Brim or no brim
Aux fan disabled
Doesn’t pertain to a specific STL as even the initial purge line can and does peel up. I’ve raised the bed temps, increased the initial layer height (as an example, .2 to .24 and .28), and increased nozzle temps.
I also cannot calibrate as those won’t adhere to any bed. I’m at my wit ends with this machine. It’s behaving worse than my old POS Qidi Xplus. I could really use some guidance.
Take a macro picture of your purge line. I am interested in the shape of cross-section of the purge line. Is it laying flat or more like oval?
But generally, bad bed adhesion relates to contamination of oil or cross plastic contamination if the purge line is flat.
Plastic like PETG and PLA does mechanical bond and chemical bond to PEI, that leaves permanent contaminated PEI surface. If so, light sanding with steel wool or superfine sand paper would remove contamination a lot better than soap + hot water.
Just list all possible causes, check them and cross them out one by one, then “whatever remains, however improbable, must be the truth”
Hey there. I am new to 3D printing and P1S is my very first printer. I’ve used it for under a month now and noticed that the printed models are pealing away from the build plate after about 30 minutes into a print. This only seem to happen in the far left and right corners and the centre of the build plate is not effected. It all begins pretty well (first layer seem to be stuck pretty well, but sometime into the print it slowly starts pealing off. I’ve done about 400 hours of printing in total now and it was never an issue to begin with. So, my issue is probably different from yours.
I’ve done some investigations and testing after following advice from the support team. I’ve set the Aux fan to 10% and closed the doors and use 5mm brim. Not had an issue since that.
Cheers
I have had this issue on multiple printers, usually resolved by thoroughly cleaning the build plate in the kitchen sink using dishwashing liquid and a soft bristle brush. Scrub well, rinse while scrubbing under running water, and dry with a clean paper towel. Let us know if you see any improvement.

Hello guys, got the same issues than you…
I juste modified the level of the Z axes on the plate i use in the starting gcode of the machine. As the following example :
;===== for Textured PEI Plate , lower the nozzle as the nozzle was touching topmost of the texture when homing ==
;curr_bed_type={curr_bed_type}
{if curr_bed_type==“Textured PEI Plate”}
G29.1 Z{-0.07} ; for Textured PEI Plate
{endif}
After G29.1, i went from -0.04 to -0.07 and it solved my problem.
Be careful with this height, be sure of what you are doing.
