Take your builds to the next level with the all-in-one CNC xPRO V3 Controller Stepper Driver! 

CNC xPRO V3 further expands the capabilities of the board and simplifies the users experience. 

 Product Details

• 4 stepper connections
• Full to 1/32 stepping
• Options for input and feedback include E-Stop/Reset, Feed Hold, Cycle Start, Homing Location (X,Y,Z Limits), and Z-Probing.
• Spindle Direction and PWM Control output
• Current limiting adjustments for each axis
• Heat sinks installed
• Latest stable version of GRBL installed

New Features (V3)

• Redesigned silkscreen (more pictures, less words)
• New/Improved FTDI serial USB interface
• Auxiliary PC fan header (12/24VDC depending on supply voltage)
• 100% Input buffering to include limit switches (prevent false triggers)
• Motor driver output LEDs
• Step/Dir breakout pads to add external drivers
• Beefed up overvoltage/reverse voltage protection
• Z-probe pin now accessible from screw terminal
• Default set to mixed decay (easily changed to slow or fast with jumpers)

Use the CNC xPRO Controller to Drive:

• 4 Axis CNC Mill
• 3 Axis CNC Mill With Multiple Drive Motors
• Laser Cutter With XY, Auto Focus, and Rotary Attachment
• Plasma Cutter 
• Pick and Place for SMD components
• Or wireless robotics (would love to see this used on a wireless quadruped)

Software Details

The CNC xPRO is designed to run the opensource gcode interpreter GRBL, opensource programming environment Arduino, or anything you can write in AVR studio.  The xPRO comes pre-flashed with GRBL so all you need to do is wire up your motors! 

From the computer side we have found that ChiliPeppr - Grbl Panel - Universal-G-Code-Sender and GRBL Controller 3.0 work extremely well (and are free downloads). 

The software stack used at Spark is:

• SketchUp, Inkscape, or Solidworks to design parts
• Openbuilds SketchUCam or CamBam 
• ChiliPeppr -  GRBL-Panel - Universal-G-Code-Sender or GRBL Controller to send gcode to the xPro

NOTE: "Please do not use the mass settings updater within GRBL 3.6.1, setting are not properly mapped for GRBL 0.9g"

Basic Setup

• xPro wiki 
• xPro GPIO pinout
• xPro schematic
• xPro quick-start guide 
• Support Forum
