Arduino CNC shield V3

Arduino CNC shield V3

Arduino CNC shield V3 is an extended shield for Arduino Uno that allows control of laser engraving machines, cnc milling machines or mini 3D printers. Shield allows up to 4 stepper motors to be controlled through the A4988 or DRV8825 driver (there are jumpers to control the stepper motor in full step, haft step, 1/4, 1/8 or 1/16 mode). It is also possible to attach additional travel switches for the X, Y, Z, E axes (for 3D printers only) or control the CNC engraving heads, laser heads and cooling fans.

SPECIFICATIONS:

• GRBL firmware support
• Control up to 4 stepper motors
• Driver compatible: A4988 or DRV8825
• Add jumpers to control the full step, haft step, 1/4, 1/8, 1/16
• Travel switches for X, Y, Z and E axes
• Controlling CNC engraving heads, laser engraving heads
• Control the cooling fan
• Power supply: 12-36V (independent of Arduino Uno)
• Size: 70 x 55mm
