Bare Board CNC xPRO

Assemble your own CNC xPRO Controller!

BOM and Placement Files available here.
 

USE THE CNC XPRO TO DRIVE:

  • 4 Axis CNC Mill
  • 3 Axis CNC Mill With Dual 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 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:

Most of these are opensource! 

SPECS:

  • 100% GRBL version 0.8c compatible
  • Capable of powering from ATX PSU (these are dirt cheap and we have tons laying around from recycled desktops)
  • Capable of powering from a dedicated 12V/24V two wire power supply
  • Drive 4 motors with DRV8825 Stepper Drivers - 2.5A (peak) with 1.75A (RMS) with up to 1/32 microstepping
  • 1 Driver capable of cloning X,Y, or Z or being run as an independent axis
  • Hardware support for both USB and Wireless Operation (XBee, WiFly, or RN42-XV)*
  • Emergency Stop to cut all motor power (with optional override)
  • 12V and 5V** outputs for powering peripherals (fans, pumps, vacuums)
  • Quickly connect to Stepper Motors and limit switches with 3.5mm screw terminals
  • Expansion port for coming upgrades (handheld jog controller, integrated spindle speed control, etc.)

*For CNC applications we recommend RN42-XV 
**5V output available with ATX PSU
