I’m looking at getting one of these machines because I need to make RC aircraft molds from MDF board to make carbon fiber/fiberglass parts. I have 2 questions about this I’m using Fusion 360 to design the molds. Sometimes I need to make positive molds. Sometimes, I will need to make negative molds. Can this machine be used for this procress? I notice that the working height of the machine is about 3 inches on the Z axis. Some planes I plan on making are pretty large. Is there any way this can modded (and still work) so that working height on 5ge Z axis can be increased to 4, 5, or even 6 inches? Thanks again in advance.
