What am I doing wrong
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
Is it a brand new printer? I could be wrong but it looks like under extrusion, blocked nozzle, did you leave it preheat for too long?
Id say partial clog. Do some cold pulls and/or purge like 200 mm at 230C. If that doesnt help get a new nozzle. If that doesnt help check extruder. Be carefull when tightening the nozzle hotend must be heated
Id purge at high speed at the max temp your hotend allows. Maybe open a window tho if you're concerned about the gasses from going above your max filament temps
I would reference a Print Defect guide, such as the following:
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).
thank you for the answer, I think my nozzle is the problem, I'm gonna try to replace/clean it
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?
Do the gaps match up with where the seams are? You can check where the seams are in the slicer. If they do match, it might be retraction settings, or it could be seam settings.
