First layer clogging

I have been suffering from my nozzle being clogged (printing PLA) for weeks and tried everything I can think of. I have the z-offset correct, but partway through the first layer the extruder starts clicking and I can see it's clogged.

Before I went back to recalibrating everything it would get a few layers up and then clog.

I've remeasured the bed mesh, recalibrated flow, reduced retraction down to 0.5 and speeds to 30mm/s. First layer print speed is now slower than my Prusa Mini. Tried tight extruder idler tension, loose idler tension. Increased temp to 220, but still click click click.

The nozzle is usually quite easy to clear, although the Orbiter makes it really annoying to yank the filament out.

Does anyone have any ideas on what I'm doing wrong? Should I just go hotter and hotter? I don't feel like I'm going fast enough to go crazy at 21 mm/s where it clogged in the attached picture.

V-Core 3.0 500, EVA 3.0 platform, E3D V6 hotend, 0.6mm CHD nozzle, Orbiter 2.0 extruder, BLTouch, Prima textured PEI sheet.
