CNC v3 Assembly Overview<\/strong><\/p>\n\n\n\n

The Arduino CNC Shield v3 works with UNO and allows control of 4 stepper motors<\/p>\n\n\n\n

To control 4 stepper motors, 4 stepper motor drivers are required, these are daughter boards that do the actual control<\/p>\n\n\n\n

There are several different models of Stepper Motor Drivers<\/p>\n\n\n\n

All Stepper Motor Drives require installation in the correct orientation, if installed in the wrong orientation, they will be destroyed<\/p>\n\n\n\n

To install correctly, find the EN or ENABLE on the CNC v3, then find the EN or ENABLE Pin on the Stepper Motor Driver board and install the Stepper Motor Driver so the Pins match up on both devices<\/p>\n\n\n\n

The cheapest Stepper Motor Drivers are the A4988, which have a Green Model and a Red Model, which are equivalent in functionality<\/p>\n\n\n\n

The next step up in performance is the DRV8825, which provides better functionality, warning – these have the opposite orientation in mounting on the CNC v3<\/p>\n\n\n\n

The A4988 and DRV8825 are common lower end Stepper Motor Drivers, and can be found on aliexpress.com for less than $1<\/p>\n\n\n\n

There are many higher end Stepper Motor Drivers, and the cost goes up considerably, All of the system I will experiment with will use the A4988 and DRV8825<\/p>\n\n\n\n

The CNC v3 Shield installs onto the UNO, and the Stepper Motor Drivers install onto the CNC v3 Shield<\/p>\n\n\n\n
