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

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
