Can I run third party hardware (edelkrone, Noxon, etc) through the DMC-16, in order to get its functionality?
The Performing Rigs equipment is made to be run via our DMC-32 (or DMC-16).
Ditogear equipment can be run via the DMC-32/DMC-16, if you have their DMC-16 adapters. (Ditogear is no longer in business.)
Other than that, most third party systems are closed systems. They have their own control signals, drivers, etc, with cabling that is not documented.
The DMC-32/DMC-16 outputs step and direction signals. These can only go to devices that have inputs for step and direction signals. Typically, that would be a stepper motor driver.
