Hi Paul,
Ah no problem. I have a similar feeling with the resin printing - the process of washing and curing concerns me a bit, but I think that's more because I dont understand it, or the machinery to do it! You have my thoughts and best wishes with the negs, I have over 170,000 negatives here ... yes I have started scanning but will it ever get finished!
I am reasonably competent with Fusion360, so if I can help feel free to shout! A friend of mine is a CAD designer by trade and having never used F360, he's a Creo man like you, he managed to teach me most of the basics (and a bit of an advance course!) within three evenings. So I doubt you'll have too many problems, but if you do shout, if I can help I am sure he will.
Thanks for the reply, and hope you enjoy the Mars printer when you get to use it!
Richie
