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 ?

If your dome is brand new (2021) then you probably have a Beaver controller (what ASCOM driver are you using if you're on Windows ?) .
This means.. you can't do the dual motor modification as you can't connect a 2nd motor to the board and as the board are full shutter controller you can't use 2 in parallel.
As for my own system, I developed a new controller for myself (dome and shutter) to replace the one based on the Arduino as the 3.x and 4.x firmware were ... not up to my standard to say the least.
As for TheSkyX as this is what I use I wrote the X2 plugin for my own controller (I also wrote the X2 plugin for the Beaver controller for the new NexDome: https://rti-zone.org/software_x2dome_plugins.php#beaver ).
X2 is TheSkyX Pro own standard to interface with hardware and it's multi-platforms (Windows, macOS, Linux X86_64, ARM32 (Raspberry Pi and the like) and ARM64 (Odroid, TheSky Fusion)).
As this is a DIY project ... it's up to the user to do the assembly. I can probably produce a few board with the component soldered but the user need to get the controller, motor .... and as you already have a new Beaver controller I'm not sure you'd want to rip that out to use my DIY controller.
