Often in our examples, we use MECHA to show you how to automate the process of taking photos for panoramic photography. But MECHA can be used anytime you need to rotate or move an object or device around an axis or along a rail, for example.

In today's video, we will show you how to perform continuous rotation horizontally and vertically simultaneously with MECHA DAC using the RAW Interface this time.

To use the RAW Interface, first connect to MECHA's Wi-Fi network using your phone or computer. Then, access the '/config' page and find the option 'Enable RAW Interface'. Ensure this option is checked, then click the [Apply] button.

Now access the '/i-example' page. Here you can see some RAW Interface usage examples and use this page to control MECHA. We will disable 'Simulation Only' and 'Auto Refresh'. This is useful when using the C2 Controller.
Additionally, we will leave the 'Absolute' checkbox unchecked so that the rotation angles are relative to the current position.
Please read the notes below for details, and we also recommend reading the chapter 'RAW Interface' in the C1 User's Guide.

Let's see how to instruct MECHA to perform a simultaneous 360-degree horizontal rotation and a 360-degree vertical rotation from the parked position. The upper rail has three basic positions for preset launches: parked, level, and raised.

When using the RAW Interface for the first time, the easiest way to send a command is by changing an example command. Click the [FishEye 6 around] button and look at the Console; all the commands are added right there. They are not executed because 'Auto Execute' is not checked.
What we need to change are the values of 'rd1' and 'rd2'.
'rd1' is the rotation angle from the current position for the lower rotator. We want the lower rail to perform a complete rotation, so 'rd1' should be 360. At the same time, we want the upper rail to rotate from parked to raised and back to parked, performing a full 360-degree rotation vertically. So 'rd2' should also be 360.
We can delete unnecessary parameters and commands.
Let's duplicate this command so MECHA will execute it twice.
Now we will click the [Execute] button and see the result.

Notice MECHA stops after the first command, then continues with the second.
What should we change to prevent that stop at the end of each command?

We can specify a multiple of 360 degrees both horizontally and vertically. For example, 1800 degrees gives us five complete rotations without any pause, which is equivalent to a continuous rotation.
The 'sp1' value represents the rotational speed of the lower rotator. You can change this value as needed. You can set a different rotational speed for the upper rotator using the parameter 'sp2'.
For simplicity, use the parameter 'sp' to set the same speed for both rotators. 
To achieve slow motion, set a lower value.
