I don't think so. (1) I was careful with retraction to avoid this problem; (2) I've checked the filament itself and found no problem of "eating".
Reading some other posts I tried reducing the temperature to 195 degrees. Using the "Move filament" control I got nice strings of filament out of the nozzle. See the picture. Using a calliper I measured this at between 0.32 and 0.56 mm diameter. So it seems to flow OK at this temperature.
So I had another go at the print. This is what I found:
And here is a detail:
After this I looked at the filament driver (the entrainure) and, following a video on the Ultimaker site, reduced the tension (white indicator to the highest position), though, to be honest, there was no obvious change.
Then I modified the temperature again, to 200 degrees. Watching the machine it seemed OK for the first 10 minutes. Then it started showing signs of under-extrusion again, so I increased the temperature to 205 degrees. It got better, but after leaving it for a while I returned to find this:
Obviously I've aborted the print now and I've given up. It's looking like I can't print anything now, at least with this nozzle. As I said, it was a new one. More accurately, it was an unused 3dSolex one bought 2 years ago.

Hi
Is that your filament does not get eaten by the entrainure during the printing ??
