Left the z calibration for another day and thought I'd try a benchy. I think I might have to check the temperature settings that I had on my proforge mk 1 as I think the ones for the mk2 might be too low for my filament. Lots of layer separation.

After taking an age to build it (health issues) I finally started printing tonight. Amazingly something appeared on the plate. Looks like I have some z calibration issues to sort out for the 2nd extruder, but all seems ok otherwise. Happy days.
