You can control your motor devices from Horus. Before using the motors, configure them in the motor settings menu where if the device has some problem this will be highlighted by an exclamation point at the bottom right.
At the top of the window you can homing and/or stop the motor. Once the homing has been performed correctly, it will be possible to have full access to all the features.
Otherwise check the motor settings menu if there is any error.
At the bottom you can move the motors in jog or set the position manually.
Choose the axis you want to move, use the + or - keys to move manually (the current position is indicated between the two keys) or enter a value and press the GoTo key to go to a specific position.
