3dprint 3d print layers are peeling themselves off

[itsosaid]

I have 2 3d printers, Wanho i3 and ender 3 and both of the printers have the same problem, the prints are just peeling themselves off from the layers.
What am i doing wrong?
is there any guide book or tutorials as to how to solve this issue?

what type of plastic are you using?

 

there's many things that can be wrong here:

- printing too thick layers for the width of nozzle you're using

- not printing hot enough

- depending on the type of plastic, moisture can cause weird issues

- feed axis isnt calibrated, so you're underextruding

- probably some more i cant think of.

What plastic are you printing with?

How are you storing the filament?

Are you keeping desiccant with your filaments?

Have you done anything in the slicer that could result in this?
