Descriptions : Arduino CNC Shield V3 Expansion Board For 3D Printer

This expansion board as a driver expansion board, can be used for engraving machines, 3D printers.It is a total of four slots, can drive four A4988 stepper motor. 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.

Specifications

1.Latest CNC Shield Version 3.02.GRBL 0.8c compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals)3.4-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)4.2 x End stops for each axis (6 in total)5.Spindle enable and direction6.Coolant enable7.Uses removable Pololu A4988 compatible stepper drivers. (A4988, DRV8825 and others)8.Jumpers to set the Micro-Stepping for the stepper drivers. (Some drivers like the DRV8825 can do up to 1/32 micro-stepping )9.Compact design.10.Stepper Motors can be connected with 4 pin molex connectors or soldered in place.11.Runs on 12-36V DC. (At the moment only the Pololu DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.

• Use removable A4988 or DRV8825 compatible stepping driver.
• The extension board can be used for engraving machine or 3D printer driver.
• Compatible with GRBL 0.8. Open-source firmware operated on Arduino UNO, converting G code command into stepping signal.
• PWM spindle and direction pin, 4 shaft support (X, Y, Z, A – you can copy X, Y, Z or use pin D12 and D13 customize firmware perform complete shaft 4).
• Compact design, stepping motor can connect 4 pin connectors or be soldered.
• This is a set of disassembled part, and you need basic soldering skills to solder them together.
