Hi Roxy

OK, I've levelled the bed back out so it's now within about 0.3mm across the bed.

I've done two test prints, one using G28 followed by G29 T n5, and one just G28. The print with just G28 seem to print better, although far from perfect. The one with bed levelling was far too close on the front-left (nearest X0,Y0) to the point where it was just blobbing.

Here's the 'G29 V4 T n5' response you wanted to see:
