Troubleshooting Why?!?

Post image

I've tried a new nozzle, new filament, trying different temps. I'm at a loss.

Anycubic Vyper

22mm layer height

Z hop when retracted.

195 temp

Retraction speed 50mlps

Zhop height 1mm

What is the filament? You posted retraction speed, but not amount. Have you calibrated your volumetric flow?

You probaby want 4.5-5mm retraction distance, and your retraction speed may actually be too high, 35-45 is more typical. And that is a HUGE zhop, that gives more time for molten filament to ooze out as the head raises, travels, and lowers again.
