Design in Progress
We need to move away from being dependent on Vention products, this will be a clean sheet design:
They are not compatible with other similar parts and are often discontinued.
Limited choices are causing sub-optimal design decisions.
Existing gantry is limited in width, the optimal solution is a gantry that is the width of the entire plot, thus eliminating the need for turning / complex navigation systems.
We have decided to use the Fam-ng Amiga robot as the base power unit for BB 3.0
The concept design is for a 20ft wide gantry, but it can be configured in many widths, definitely smaller and possibly larger with further engineering verification.
