I have a 2006 Feeler VMC with a carousel toolchanger and Mitsubishi Meldas 60S control.

I don't know the proper toolchanger command format or I might have a functional problem.

Is there a toolchanger dry run program or cycle I need to run?

The machine was shipped to the US from China. It thinks tool #20 is in the spindle.

If I program M06 T01 in MDI and run it, the spindle goes up, the carousel moves right, the spindle rises and the carousel rotates more than 360 degrees and then throws an error.

If you have a tool in the spindle, than you first should remove it. If no other method is provided, you should search for the solenoid valve for the Toolcylinder.
If you have access to the parameters, you should look for the toolrevolver. I think there is a parameter who is called "axis is modulo" or similiar, then try to change it from 0 to 1 or viceversa.
