Advice on stringing only on circles?

[celoranta]

Hi All.

Still working on printing a chassis I’ve mentioned in several other topics.

P1S
0.4mm Stainless Nozzle
AMS
PETG-BASIC

I get layer issues and stringing when the hotend moves in circles:

In this case the problem showed up in the early layers of a ‘tree’ support.
I’ve had many other cases where even small circles fail… not always due to stringing.

Just cooked this filament for 2 days at 85C, so it shouldn’t be moisture-related.

Any advice?

Couple of things come to mind:

1. Speed. Slow down the speed. Use either the profile or check the quiet mode during printing.
2. Change print to Outer/inner
3. Change to avoid crossing walls which will force the nozzle to minimize moves when moving through or near circles.
