Would you call this "stringing"?

Hey. On my X1C with PLA Matte/PETG HF/and TPU I often get these “strings” on the first layer. It’s usually fine but every now and then it’ll cause a failed print.

Would this be called “stringing”? Usually happens either when there’s an internal bore, when the first layer is done and the printhead moves to wipe, or after the auto flow calibration when the head moves over to print

That’s on Bambu’s PETG HF fully dried for like 3 days straight lol, and manually calibrated [both Flow Dynamics and Flow Rate] just last night. Machine was recalibrated a few days ago as well.

What’s that called, is that normal, and how can I minimize this?

EDIT: Oh no [it’ll be fine]:

I would refer to that as oozing. It is material coming out of your nozzle during a travel (where, I assume, the extruder is not being commanded to extrude)

Is your retraction on?

If the flow/PA cals are good, it’s not dry. For whatever reason, your dryer didn’t do the job. I print a lot of PETG. Fully dried it does not ooze or string.

Unfortunately, the forum no longer appears to let you embed a larger image that can be seen by clicking the inline image in a post. So I can’t zoom in to look more closely. But this booger is pretty big and it looks exactly like what a moisture-induced ooze should look like.
