I just curious that nobody here not to build diy waterjet. It is because too expensive. What I want to ask are:

1. Is there any different between waterjet gantry and plasma/router gantry. Maybe its strength?
2. If gantry is the same, can we add waterjet head on z axis instead of router or plasma.
3. Should we use specialized control? Can we use mach3 and gecko or...?
4. Parts for water jet?

Thanks.
