I’m using regular black overture pla. I was having issues where my prints were losing bed adhesion and going off the bed at the start of my prints. I slowed the first layers waaay down, to observe what was going on. And it looks like I’m not printing with proper flow or something?
Dynamic flow calibration is turned on btw.
I have a brand new mini with maybe 40 hours of use. It has always performed perfectly until I changed from a generic black PLA to a generic marble PLA. With the marble every thing is fine except for the first layer that looks something like yours. I’m guessing it’s an extrusion issue, but, like you, I don’t yet know.
How does it look in the Slicer? Maybe another pattern will help.
As it turned out, the marble PLA I was trying to use (Duramic brand) clogged both-- my new A1 Mini and my new P1S. I’ve ordered a 0.6 nozzle to see if the filament can be used with that larger diameter. Oddly, I never had any problem running it through a 0.4 nozzle on my primitive Ender 3s with their brass nozzles. I’d like to experiment with different settings, but its a PITA to unclog a nozzle on the Bambu printers. I’m used to merely chucking a ten cent brass nozzle on the Ender 3. So cheap, why bother trying to unclog them. $35 bucks for a new (complete) hot end for the Bambu P1.
I have start putting glue on the bed for any small print pieces. Cause once the machine starts going faster it would knock lose my prints. It works great.
