Upping the flow isn’t the problem then. In my experience, flow only ever varies between 95 and 105%. It’s there to compensate for thinner or thicker than expected filament. The under extrusion is caused by something else. Possibly a blockage, possibly to much drag. Pushing harder, aka more flow, might not help.
Comment on I'm doing something wrong; can't print this PETG
csm10495@sh.itjust.works 1 day agoWhat’s the recommendation to fix under extrusion? I tried changing the flow in cura to 102 then later to 118… no obvious differences.

PETG isn’t very tolerant of too much retraction. Given your fine first layer I suspect you’re developing a clog as the print goes on, which would result in under extrusion. Turning retraction completely off will make it very easy to rule out as a possibility.

What should I see differently with retraction off? Like it failed but what should I look for then try next?

Did it look more solid or did print quality basically remain the same?

It pretty much self clogged a few layers in. So about the same?
