Hergonoway my hero!

That has improved things a lot (1mm wipe and retract during wipe) - still not perfect, but I can tweak further from here.

I've tried those settings before, but obviously not in the right combination. I thought it looked like it needed a retraction at the end of the inner perimeter, but hadn't fully comprehended how the wipe worked.

It is quite a long Bowden (approx. 55cm Capricorn tube), so I was anticipating some nozzle pressure problems.

Thanks again.

Did you manage to solve your blob problem?

I've recently converted my Hypercube to Bowden (Titan with a V6 Hot End), and I'm getting blobbing on my Benchys very similar to yours. I've been able to determine the blob happens at the start of the outer perimeter as the nozzle moves from the inner perimeter, so I'm pretty sure it isn't retract related because there is no retract move at that point.

I've tried just about everything I can think of (tweaking temperature, extrusion multiplier, pressure advance, speed, acceleration,jerk, retraction etc), but I can't get this blobbing to go away.
