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.
I changed the temperature setting for the hotend and had success. It does depend on the make of
filament as to the correct temperature. When I find out what works I write it on the spool so I don't forget.
I had a same problem in first print.
I don't know why I also wait for others comment
