Hello, I have installed a second shutter motor controlled by a second driver TB6600. I wired the signal ports from the original driver parallel to the second TB6600. I connected the second motor on the power side of the TB6600 and i inverse the red and blue wire to make the motor run same direction as the original one. Everything works good when i use the rocker switch on the shutter assy, i open the shutter and when reaching the sensor it stops, the same when i close it. When i connect the pc via Device Hub, if i command to open i just hear a clic and nothing move. then I open the shutter completely with the rocker switch and then command the closing via pc and it close but trying to reoppen it via pc does the same clic and nothing move. I can see something different from the past : I do not see anymore the shutter position on the nexdome window ?? I dismentle all my new hardwares and tried it with the original config and the problem is still the same. I updated the firware but no result ?? did someone do this modification and what is your opinion about my problem ?

The Beaver board integrate the stepper driver on the PCB so you can't drive 2 motor, only one. Don't even try to connect 2 motors to the stepper terminal on the Beaver as it would probably kill the Trinamic stepper driver on the Beaver (too much amps being pulled)..
Also if you have an existing rotation controller that is not based on the enw Beaver board, it can't talk to a shutter Beaver... both controller need to be of the same type (rotation and shutter should either be the older Arduino type or the new Beaver ones, you can't mix-match).
I use my own controller ... and my own X2 dome plugin for TheSkyX :

I'm in the process of adding the 2nd motor controller and stepper on my 2021 shutter, along with some potential other hack on it.
