PS, this is a cross posting in OneCNC, MadCAM and VisualMill threads here.

Hi there,

Our setup is as follows:
Rhino 4 and currently 5wip for all surface modeling
Alibre expert for all solid modeling
QuickCNC with syntec controller and 4th rotational axis

I'm trying to evaluate what we could use aside from the AlibreCAM (part of Alibre Expert which does only 2.5D work), to machine both alibre models and Rhino surfaces.

Our main machining needs will be high density PU foam and Resin boards (Rhino surfaces), followed by aluminum parts in 7075T6 (alibre designs, which can be easily exported to Rhino in Step format).

In the evaluation process I have shortlisted the following:
MadCAM
VisualMill
OneCNC

I'm sure that you folks have already treaded the selection that currently I'm struggling with. So can you please give me your reasons for going with OneCNC. Something else that comes to mind is: Suppose I have a model in Rhino, I generate the tool path for it and now I make a small modification, will I need to do all the tool path generation again? Anyone here who's got a syntec 940M controller and knows how to generate post for it?

Thanks a lot,
N
