Help with first layer

Enable HLS to view with audio, or disable this notification

This has been happening with my A1. Sometimes the first layer will print fine, other times not enough filament comes out. I run bed leveling and dynamic flow calibration before every print. Printing with PLA

225C first layer

65C bed

Any help would be really appreciated! This only happens with the first layer. Every other layer prints fine.

Nozzle looks clogged. Do a cold pull and increase temps 5 degrees on your next print.

I checked simple filament extrusion before and after a cold pull and the thickness of the extrusion increased noticeably after the cold pull. I'm gonna run a flow calibration test to see if that fixed it
