This contains the design information pertaining to the arm itself with regards to wiring, layout, possibly software for the motors etc.
Current diagram for the arm connections from the Arm section in the drive.
What motors are used on the arm?
Motor drivers for the base (stepper NEMA 17 or 21), Claw rotation (stepper), Upper Joint Mount (stepper), and future revision (mid joint stepper but is actuator presently) use TB6600 (https://www.robotshop.com/ca/en/tb6600-stepper-motor-driver.html)
