Having never needed to use a servo my best guess would be the same port as is used in FDM printing for a bed level sensor From what i can see it goes on AUx 1

One thing you have to remember is that it is drawing power from the arduino so be careful not to overload it !!!

I think you need to do more research on servos and servo control in order to understand what it is you are doing. I would certainly recommend detaching the servo from your printer while you experiment.

There are 4 3-pin headers next to the reset switch that are for servos. Depending on your Marlin firmware and g-code command, it should be one of those. I am not at my machine right now, but I believe I used D5 (3rd connector from the left on this image).

Sorry for the delay in getting back to you. I got the M codes from the muve3D installation guide.

Shutter open:
M280 P2 S160
Shutter closed:
M280 P2 S10

The values control the angle, so you will need to test them to get the correct angles for open and closed.
