Hello. Sorry for my bad english.
This is the first time I try to print a big piece on my P1S.
The piece is peeling off at the ends. I print with PLA, and I tried to put the bed temperature from 55°C to 70°C whithout success and I tried to make a bed leveling before printing without success to.
How can I fix this issue please ? It seems that the problem appears on the periphery of the bed.
Thanks.
Hello. Do you have the “aux fan” turned off? I would make sure the “aux fan” is off and also clean the build plate really well.
Also, use glue on the build plate. If it still lifts, consider using a brim with zero clearance around the part for greater surface contact with the build plate.
And meticulously clean your bed with water, dishwashing liquid and a clean brush. Especially after having increased the bed temp as that can “bake” hard to remove residue/contamination into the textured plates valleys.
You can print a full area, single layer height cube primitive to check your plate condition.
For large/long objects, you may also want to use mouse ears to reduce the effect of warping.
Besides a brim you can try placing tabs at the corners in the slicer. This will help hold the ends and corners down
Before trying to level the bed, check the first layer to make sure it is even. Just start your print, then stop it when the first layer is done.
If it looks like you need to tram your bed (physical leveling) there are instructions here. (X1 and P1 are done the same way).
Thanks for all anwsers. I’ve just washed the bed and try a new print with a brim and aux fan off.
Alternatively I’ll verify the bed leveling knobs after the print.
Which type of glue can I put on a tectured bed ? I’ve never put glue on this plate since I bought the printer.
Unless the printer is in a cold room, PLA should be printed with door open and/or glass top off.
it looks like good with brim 0.
the printer is in an office where the T° is about 17/18°. I’ll try without fan and with all doors and glass open (or just the door open because of ams).
Thanks 
You can dissolve a small piece of PVA glue stick in water and use that to create a nice, thin PVA film. Or go for the (overpriced) liquid glue.
Regarding open or closed lid/door, I always print fully closed (chamber temp usually at 39°C with a 55°C Smooth PEI) to minimize warping and curling and never had a heat creep related failure with PLA. Except for the one time where I used ironing!!!.
I use Bambu’s liquid glue (<- click on highlighted text to view in Bambu store) for both textured and smooth build plates. It works very well and is water soluble so easy to wash off when cleaning the plate. The bottle has a foam head for easy application.
I will test that asap.
thanks
I put a chunk of Elmers glue stick in a small spray bottle, add IPA and let it sit for a while. The stick dissolves, making a slightly thick liquid that evaporates quickly, leaving a fairly even layer of glue on the plate.
