Initial Layers Problem....

[nick_moss 0]

Hi, I'm new here and I could really do with some help to point me in the right direction.

 

I'm using Cura 5.2.2 on a Creality CD-10 printer and I can't get a satisfactory print - I am using Sunlu PLA Plus filament. I have no problem with the print adhering to the glass plate, but it seems that whatever settings I use, and I'm on about print number 50 with everything that I've tried, the first few layers are not printed correctly - please see the picture. Really frustrating. The first few layers appear to be unfused, but the nozzle heat setting (225) and bed setting (75) are unchanged throughout the print and the the remainder of the print is quite acceptable. I've tried Skit, Raft and Brim and all yield the same result. I even print upside down and the part that was previously good exhibits the same problem, so I know the STL file is good.

 

Any suggestions anybody?

Not sure if this will help but i have printed sunlu pla+ at nozzle 225 and bed at 40 with no problems.

not sure if this will help but ive never had my bed above 60c for PLA (or pla+) maybe its too hot?

also is your first layer perfect i mean maybe you are too far from bed and its just barely sticking? use hairspray on 60c glass bed before print works for me. also do you have mesh bed leveling enabled maybe its not working correctly and it usually tries to turn itself off gradually by 2mm tall so maybe thats something to check (make sure bed is perfect and disable mesh leveling)

 

let us know what you find out!
