UNO CNC-Shield V3

If you need control several stepper motors with an Arduino UNO board, this CNC shield should be the perfect board for you. It is well designed board which will house 4 stepper drivers and allow easy configuration of parameters ( Example: configuring the steps of stepper controller with jumpers). Combining with this stepper driver, A4988 you can drive 4 stepper motors.

The shield allows external power supply upto 36V for powering powerful motors, Also has the pins for setting up end stops, hold & resume operation.

• Arduino UNO shield form factor, compatible with Arduino UNO, UNO.
• GRBL v1.1 compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals)
• Uses removable A4988 compatible stepper drivers (Not Included) PWM Spindle and direction pins
• 4-Axis support (X, Y, Z , A-Can duplicate X,Y,Z or do a full 4th axis with custom firmware using pins A4 and A3)
• 2 x End stops for each axis (6 in total) + one Probe
• Coolant enable output
• Jumpers to set the Micro-Stepping for the stepper drivers.
• Compact design.
• Runs on 12-35V DC. (Depending on Stepper driver
