Take your builds to the next level with the all in one xPRO CNC Controller! 

 SPECS:

• 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
• Heatsinks installed
• Latest stable version of GRBL installed

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

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)
• E-stop now tied to hardware and software
• Uses the ATmega328PB (new version of the ATmega328, includes more timers, USART, etc)

USE THE XPRO CNC 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:

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 we use here 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"

Most of these are opensource!
