Can warping be solved with higher bed temperature?
Hi,
I think there is a spot on my heated bed where my 3d prints (always) warp or even come loose (even with brim). I will check it with thermal camera (later) to see if it is still heated but in the assumption the heatbed is OK, can I solve warping/sticking with a higher bed temperature (printing with PLA)?
The glue (that came with the printer) helps but is a bit messy :p

Hi Mario,
I think you may be using a Sledge hammer, to Crack a nut...
Glue stick is provided to reduce adhesion for PETG Prints
I don't use any of the other surface treatments, no IPA, No Hairspray, No Magigoo, No Painters tape, JUST CLEAN Prusa PEI sticker, or Clean Prusa Powder coat. 
occasionally I need to add a Mouse Ear, on something that is Pointy (Sharp corners tend to lift) these blue mouse ears are 5mm diameter, 0.2mm thick. in this case I am using a Prusa Textured sheet.
PLA 'Should' Bond well to a prusa build plate without need for any other surface preparation apart from being clean and contaminant free...
I make sure 7x7 Mesh Bed levelling is turned on,
(LDC Menu option under "Settings>Mesh)
then I take my build plate to the kitchen and clean it very well with Hot Water and a touch of dish soap (Basic Dish detergent, like Dawn or Fairy liquid)
I rinse well, and dry with plain paper towels, then I do not touch the clean surface with my fingers... 
I use 'Life Adjust 'Z' My Way'
https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-assembly-and-first-prints-troubleshooting/life-adjust-z-my-way/
to set live Z (In preference to the Prusa first layer calibration tool)
then when I slice my own files, I set the heatbed to 65C or 70C

@joantabb
Do you use something THAT abrasive on the build plate?

Hi Matto, Some folk use 1000 grit wet and dry paper, I generally use the yellow side of the sponge, the green side doesn't appear to damage the powder coat if you do use it...
