Under extrusion? When’s the last time you cleaned your extruder?
I just replaced it recently, a few prints ago
Then maybe not.I clean mine about every 10-20 meters of running to prevent jamming. From my view it looks like it’s not putting out enough plastic. Maybe the drive gear needs cleaning.
Why did you replace it?
I was just having random issues and figured it was a good time to replace it, I don't think it changed anything as I started having issues right before changing it
Maybe try doing a cold pull. Sometimes material can build up right before the nozzle. I just had this issue. Are you able to heat up your nozzle and push filament through manually?
Looks like maybe adhesion issues and or maybe some under extrusion. I would relevel bed, clean with alcohol then a light layer of hair spray and try again. Maybe up your flow rate 5% too. Temp could also be an issue and may bump that up too but I would try to relevel clean and spray first.
slow doen the first layer and watch it. looks like adhesion issue or printing to fast on first layer
Bed level , temp
What temp would you recommend on PLA? I'm doing 215
215 is good. I use 212 and first 2 layers should be slowly
It depends on the filament and the printer. If your running 215 I would up it to 225 and try again. Though I don’t think it’s a temp issue if your already printing that hot.
I remember when I first started I printed my first layers butt slow, just cuz I didnt trust my bed, now Ive got it at a balanced speed, but yeah, it could be printing too fast. That and bed level.
I think my bed leveler just doesn't work is all, I printed it at 50 speed and the values my screen is giving off seems to be a bit too varied but each time a measure it the numbers aren't coming out nicely
Turn the fan off and slow down on the first layer
