DESCRIPTION The Arduino CNC Shield is a board designed to allow Arduino Nano 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 fits the Arduino Nano board and provides the connection between the Arduino Nano 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, houses the stepper motor drivers. The shield supports up to three stepper motors, each of which can be controlled independently. 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 3-Axis support (X, Y, Z) 2 x End stops for each axis (6 in total - each axis pair shared by same IO pin) 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:7.5 - 12V Compatible: Arduino Nano SHIPPING LIST 1x CNC Shield V4
