CNC Shield V3 Engraving Machine Expansion Board A4988 Driver Expansion Board for Arduino 3D Printer CNC A4988
- CNC Shield V3 Engraving Machine Expansion Board: Compatible A4988 or DRV8825 stepper drivers
- Input Voltage: 12-36V DC
- Each road stepper motors only need two IO ports. In other words, six IO ports can be well managed three stepper motors. Very convenient to use.
- Stepper motor wiring as follows: 2A, 2B is a group (red, green), 1A, 1B is a group (blue, yellow), if want to change direction, can be change the position of one group , for example 2A, 2B mutually exchanged.
- GRBL 0.9 compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals)
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 D12 and D13)
2 x End stops for each axis (6 in total)
Coolant enable
Uses removable A4988 or DRV8825 compatible stepper drivers
Jumpers to set the Micro-Stepping for the stepper drivers. (Some drivers like the DRV8825 can do up to 1/32 micro-stepping)
Compact design.
Stepper Motors can be connected with 4 pin molex connectors or soldered in place.
Runs on 12-36V DC. (At the moment only the DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)
Please note that this is an unassembled kit and Basic soldering skills are needed
