If you’re slowing down significantly and seeing an improvement, I wonder if it’s an adhesion issue vs an extrusion issue. It is very weird that it’s so localized though. I almost wonder if the nozzle might be influencing things somehow. Is it clean? Get it up to temp and give it a wipe with a folded over paper towel.

I’ve cleaned the bed and not applied 3DLAC, and it hasn’t helped.

  That’s disappointing. I’m sorry to say, but I’m out of ideas. Maybe try the Voron design forums since they have more active users?

I tried a never-used nozzle with no difference.

The bed hasn’t been cleaned in a while, but the parts that aren’t underextruded stick very hard. And it happens the same in every place on the bed (I’ve tried about 8 now, always with the same pattern) and 2 different beds.

I’m still thinking it’s a pressure issue, where it initially doesn’t have enough pressure for some reason. But I turned up the KAMP purge flow and it made no difference, and extruding 2 skirt lines made no difference that I could tell.

My next step is going to give the bed a good cleaning… And even try the other side that I’m pretty sure I’ve never used yet.
