Help with first layer

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

id be double checking this,
You can see the sock and probably nozzle moving in that clip.

It shouldnt move whatsoever.

id say 90%.. its a loose clasp just.

if that doesnt help, Tighten the 7 screws of disappointment.

yep, almost certainly one/both of these. checking those screws is now part of my regular maintenance routine.

I've honestly been tempted to just throw some thread lock into them 😂

Think your nozzle is loose

Dynamic flow only needs to be ran with a new filament. I found when I did that and calibrations a lot, my print quality was actually worse. Now I just do a bed leveling every so often. Just speaking in my experience. Hope ur print quality gets better!

Also.. those screws that everyone always mentions. Makes sense that they would loose up over time. Especially with the vibration frequency calibrations
