first layer issue - blobs  

Re: first layer issue - blobs

good morning Hamza

the Prusa first layer test is not very good.

try downloading the files at the bottom of the first post in the following thread
https://shop.prusa3d.com/forum/assembly-and-first-prints-troubleshooting-f62/life-adjust-z-my-way-t2981.html#p125948

it would be good to see the pictures.

use the attachments tab below the message window when writing a post

files like gcode and STL need to be zipped, but JPG is ok without zipping

regards Joan

Re: first layer issue - blobs

I ve uploaded files as attachments now.

So basically, my layers are sticking well to surface, but they arent equal despite calibration and auto leveling.

UPDATED photo "issue4" - last test at 0.702 Z height with test from "jeffjordan" and my results are now better, but now my layers are separating, and on one side not bonded between each others.

Re: first layer issue - blobs

Hi Hamza,

that seems to be a great improvement on your previous attempts,

next you need to do the bed level correction test,

this tests the outer edges of the bed

if you download the attached zip file,

and unzip it, there should be three files, a 200mm square pla test file, a200mm square PETG Test file and an STL for a 200mm square, in case you want to make a test object for a different filament

when you print the appropriate test file, the printer should try and print a square, using concentric infill...as this starts to print you may notice areas where the filament does not stick and areas where the filament is too squished

stop the print, and go to bed level adjustment in the LCD configuration menu.

if your front edge of the filament is not sticking, then change the front edge setting, more negative
if the back left corner is not sticking, then adjust the left side and the back side values more negative

if a side or corner is squishing too much then adjust that side or sides more positive

then try printing the 200 mm square, again if necessary re adjust ant test,until you are satisfied,

regards Joan

After Bed level adjustment calibration my layers on corners showed good results untill it passed few more layers.
As you can see on photos , issues appear:
- Right front corner (inner side of print) has curling/wawy delaminated effect
- Left side is improved, but still has gaps
- Overall inner layers are totally separated from rest of the print, and made huge mess?

Re: first layer issue - blobs

Reduce your bed level correction negative values a little on the right and left. And try again
