Yes Christian confirmed, I did email him to see weather his developing a workaround but he's not got back to me yet.
I think Oozenest have a relationship with Vectric so probably tricky for them to recommend another platform.
As it seems a bit vague which software (outside of Fusion and Ventric) will work with Duet, I might buy an Arduino system for the short term and use that to make life easier while I'm starting out.
