Thinking of a new 2 axis build. It would require 4 actuators - 2 for each axis. The Blackbox makes it easy to slave one axis (using Y and Y2 ports) but not sure how to go about slaving the other two actuators that I'd like to use for the second axis (that would be plugged into the X and Z ports). Looked through the docs and it looks like the jumper can only be moved to change which axis the Y2 port is slaved to. Thanks
You can wire two motors in parallel to one output, provided of course they each get less current than if they had their own driver, but usually still more than adequate
