boelle:
i just click verify/compile as i dont have the printer close enough that i can upload
That's fine. From your previous error message I couldn't tell if the problem was occurring during compilation of upload. Now I can see it's during compilation so it would never get to the upload anyway.
Try the attached boards.txt file, following my previous instructions. I only added the new modifications to the [BootloaderCDC]SAV-MkI board since that's the one your error message indicates you're using.
