But it always shows error "Not a valid motor controller firmware file".
I tried to install that via hand controller but still same error.
Then I installed this driver "Firmware: Universal Stepper Motor Driver with Built-in USB port, Version 3.39" for my Sky Watcher AZ-EQ6 pro. It worked but can't fully use it. When I use PHD2 guiding it always say pulse command to mount failed. Please help me.
