I have creality cr 10 smart pro and totally new to printing. I calibrated it well with cube and heat tower prints. Using PLA at 210C and 60C bed temperature. I’m having this issue sometimes. How do I prevent this Thank you

    I would reference a Print Defect guide, such as the following:

    https://all3dp.com/1/common-3d-printing-problems-troubleshooting-3d-printer-issues/#section-fdm-3d-printing-problems-my-print-looks-bad

    Perhaps the section for “Some Layers Are Missing”

    The absence of material leads me to an under-extrusion, though that could be influenced by a few things.

    Your reported temps are fine, looks like bed adhesion is ok. So if there is an absence, the plastic didnt make it there. You have to ask why. Is it a restriction (resistance in the movement of the filament), filament defect (water content), extruder issue (nozzle), cascading first layer issue (clogged nozzle/z-cal).

        I’ve been 3D printing for years and this looks like a nozzle clog to me. The other possibility would be underextrusion but I’d put 5$ on this being a clog. Have you been using multiple types of filament?
