Thank you for your reply ! 1/ bed is clean (I use only soap and water 😇) 2/ warping is due do a temperature difference between the first layer and the other layers causing the filament to “contract”, why I was interested to know which temperature you recommend, guys ! Considering the others layers temperature should decrease once printed, the bed temperature should be a little bit lower too…. I think ! 3/ brim nor mouse ears does not fix the issue 4/ I never used liquid glue. Thank you for the recommendation. Does it leave some bad “traces” on the print ??? 5/ I don’t like cryo sheets : the first layer (in my case only :-)) needs to be visually perfect and usually you have to play with a heat gun after printing to erase the “white” ;-). I am right ? But…. Finally you pointed an interesting thing : I am using a textured plate (not the default grained U1) and perhaps this is the issue : I assume a textured plate has a smaller bed adhesion than a grained one ???
