Just a place to dump ideas for now.

We need to move away from being dependent on Vention products, this will be a clean sheet design:
|
...
Many motion components are overkill.
...
Cost is relatively high.
Motion Control System
ClearCore Industrial I/O and Motion Controller Platform; $99 (teknic.com)
...
Integrates with servo or stepper motors and sensors easily
Provides all necessary I/O
Relatively easy to program (compared to other non-purpose-built options)
Small, easy to integrate
VERY flexible
Can work standalone or controlled by an external PC like a Rpi or anything else
Low cost
CPM-MCVC-2310S-RLS | torque = 223 oz-in, speed = 4000 rpm (teknic.com)
...
Integrated motor driver and position feedback
Much higher power for the size than steppers
Good IP rating for weatherization
Integrates well with ClearCore motion controller (although they can both work with other 3rd party systems)
Large voltage range, can be directly battery powered

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.
