Hello @Nomad, it looks like you are getting some lift on your print. This is likely an adhesion problem, try these things:

1. Print with a raft
2. Level the build plate
3. Clean the build plate with isopropyl alcohol to remove any grease that may have come from your hands
4. Scuff up the build plate with sandpaper or whatever you can find

Hope that helps!

hi jeremie

i have level the bed with the blue tape on it.the 4 corners are good but in the middle is not so good. thats why i thought the bed was not good.okay adhesion means ( stycky problem  ). i have isoprofyl alcohol ,

thanks jeremie.

Nomad, put UHU stick glue on the blue tape for better adhesion. For slicing i use Repetier-Host : https://www.repetier.com/download-now/

the sticky problem is solved.but i notest the bed is bend.also i see a missing page in settings on the printer. i dont see this page as in the pic. do you have an idea ,if you use your android phone as wifi for the cura,will that cost alot? i have a look on your link.and i have UHU sticks. thank you for responding.

You have too much air circulation and the pla is cooling at different rates. We resolved this by placing a box over the printer.

Also, the other main reason for lifting on the edges is due to the plate being too far or too close to the print head.

Take some time to calibrate the print head against the bed as often as possible.

hi dj my printer sits in a closed. i level the bed about 30 min and in all corners and middle. the bed is bend i cant get a good bedleveling. i bouth this on ebay,new in box.i think the seller got me there.
