Dear Daid,
Thanks a lot, will try!
Concerning the mechanical problems, i am not aware i have. Sometimes the first part of the first layer(s) go well, but later on it gets worse, and the platform seems rather flat.
This problem exist mainly with thin walled items, but we want ot be able to produce those a welll. like you're saying, it's not functional to keep messing.
Rgds, Paul
