first layer problem  

Re: first layer problem

If you haven't seen this thread https://shop.prusa3d.com/forum/-f6/life-adjust-z-my-way-t2981.html , that is the best way to make sure your live z is correctly tuned.

Also make sure that the bed is correctly cleaned up. Once these 2 things are take care of, things will work fine.

Hello ibrahim,

did you already try to clean the Printbed/Steel sheet?
If your first Layer Calibration is (quite) ok, it is possible that you have some kind of grease etc. on the flexplate.
Even touching it could be enough to cause adhesion "problems".
Give it a good wash with disch washing liquid and dry it with a paper towel.

Hi Ibrahim,

for larger prints you sometimes have to adjust settings for the edges of the bed

these adjustments can be found in the calibration menu on the LCD

under the Bed Level Correction option
you can adjust up to +50 micron or - 50 micron as required.
