    print hotter 190 ?
    wow. Don't think I've ever printed pla lower than 200 and 210 is my standard for 90% of prints.

    Corners are lifted because you've got shrinkage - it's slightly fatter due to the 'smoosh'.
    With some filaments you can't get round it.
    But try printing it at 210.

    Also fan off for first two layers and print the first layer very slow.

    I tried printing at 210 but something went wrong and the top of the dust boot became a spaghetti mess. I'm printing at 200 and I hope that it will work.

    What's the best way of cleaning the PrintBite surface? I tried leveling the bed and cleaning the surface with 70% Isopropyl Alcohol. Sanding the surface with very fine sandpaper and then cleaning the surface with alcohol worked in keeping the first layer flat.

    A quick wipe every couple of months with a little acetone on kitchen paper is all i do.

    why would you sand it ?

    Before I sanded the surface, most prints failed because of layers lifting off the surface. My printer has dual extruders. I didn't know that I can use acetone to clean the surface.

    yes you can - I always have.

    what do dual extruders have to do with it ?

    I think that the extruder not being used try to lift layers off the surface. I know that some of the new 3D printers have two extruders that move independently of each other.

    ah right, yes if your nozzles aren't perfectly level they will cause problems. In the end I removed the right nozzle from my flashforge creator. Never used it. All that side has now is a printed stepper motor shape - you ned it to engage the endstop :-)

    I know the thread was revived after a couple years but just wanted to add some important info for others who get here from google.

    There's a lot of misinformation in here.

    Most notable fixes: don't use alcohol on printbite and increase bed temps slightly.

    PrintBite has helpful instructions on their site:
