DESCRIPTION
The Arduino CNC Shield is a board designed to allow Arduino boards to control various CNC machines, such as routers, mills, and lathes. The shield is compatible with a variety of stepper motor drivers, including A4988, DRV8825, and TMC2208. It provides a convenient interface for connecting stepper motors, limit switches, and other components to the Arduino board.
The shield consists of two main parts: the control board and the driver board. The control board is the base board that sits on top of the Arduino board and provides the connection between the Arduino board and the driver board. It includes various pins for connecting the stepper motors, limit switches, and other components. The driver board, on the other hand, sits on top of the control board and houses the stepper motor drivers.
The shield supports up to four stepper motors, each of which can be controlled independently. It also includes a spindle control pin for controlling the speed and direction of a spindle motor. The spindle control can be used for various purposes, such as controlling a router or a milling machine. Additionally, the shield includes pins for connecting limit switches, which can be used to prevent the machine from moving beyond certain limits.
The Arduino CNC Shield is programmed using the Arduino IDE and a CNC-specific library, such as GRBL. The library provides a set of functions for controlling the stepper motors and spindle motor, as well as reading the limit switches. The CNC machine can be programmed to perform various tasks, such as cutting or engraving materials, by sending commands to the Arduino board via a computer or other input device.
FEATURES
- 4-Axis support (X, Y, Z , A-Can duplicate X,Y,Z or do a full 4th axis with custom firmware using pins D12 and D13)
- 2 x End stops for each axis (6 in total - each axis pair shared by same IO pin)
- Spindle enable and direction connection
- Coolant enable connection
- Uses GRBL as control software
- Uses removable stepper drivers (DRV8825 or A4988)
- Stepper motors can be connected with 4 pin dupont/molex connectors
- Jumpers to set Micro-Stepping
TECHNICAL DETAILS
- Input Voltage: 12 - 36V (only the DRV8825 drivers can handle up to 36V so if using A4988 do not exceed 24V)
