I'm in progress printing 3D part of AR3 and read through the user guide. I notice 1 section mentioned
Please note this assembly manual does not show wiring of the enable circuit. The enable circuit will likely not be used by most and is used to disable the motor drivers. The enable circuit disables each of the motor drives when 5vdc is applied to the enable terminals on the driver.
I thinking is it possible during assembly process i prepare enable/disable switch for all joint, so we can hand hold 'train' and record robot arm movement?
i'd tried assemble the AR structure (only), stepper motor off seems allow all joint (1-6) move by hand. I know it still have far way to go (especially software and route planing), but at least it tell me AR3 is possible to train by hand. However, i notice backlash at some joint. hope it not effect my research.
