It is your responsibility to read, understand, and adhere to the applicable documentation for this controller board and any other devices that are to be attached to it.
Lack of adherence / compliance to the equipment manufacturer’s documentation and warnings can result in equipment, personnel, and property damage.
Do not use any power supply while wiring the board unless you're asked to do so.
If you have the WiFi version of the Duet 3 Mini 5+, don't forget to connect the external antenna. Ideally, mount the antenna and Duet on your machine first.
The antenna connector is quite a tight fit, and is not intended for frequent connecting/disconnecting.
Carefully align the connector as square and straight as you can before firmly pushing on.
You can also unscrew the aerial from the other end of the cable, which you'll need to do to mount the antenna, and leave the other end connected to the Duet.
The antenna mounts through a 1/4" or 6.3mm hole.
The antenna is not shown in the forthcoming photos.
Never attach / detach motors when the board is powered!!
Never blindly trust stepper motors’ wiring colors, always check phases. Mixing the phases up on the 4-pin connector can and often does result in damage to the stepper driver. Be especially careful when using stepper motors with detachable cables!
