So I ended up with a Mk8 0.4 CHT Nozzle. 
I thought to install it on the Artemis to see if I could speed up it's print speeds and maintain quality. I'm mostly printing PETG and some PLA. 
I installed it but now when I delta calibrate all seems fine until I print. I'm scratching the glass with the nozzle. I have to baby step 0.3 mm above the glass to get a decent first layer. Is there some setting I needed to change in terms of the z-offset? Shouldn't the delta calibration get me closer than 0.3 mm off? 
Any help would be very much appreciated.

Re: 0.4 CHT on an Artemis
Are you running the 3.4.4 firmware?  If not, it cures a lot of weird little calibration issues - just make sure to no use the bed mapping function as that's still problematic.  The instructions for that are here: https://docs.google.com/document/d/1IQf ... share_link

Re: 0.4 CHT on an Artemis
Yes I'm using 3.4.4 and not meshing, just using the wavy delta calibration icon. 
Nevertheless even with the Z-offset set in cura, I could not get the CHT to print well. Went back to a 0.5 seemecnc nozzle out of pure frustration. The CHT just doesn't seem to be a good fit for this machine and PETG.
