The CNC xPro V3 Controller is a complete multi axis GRBL Controller. It is a specifically designed CNC Controller for applications that require precise motion control. The CNC xPro V3 is equipped with 4 embedded DRV8825 Stepper motor drivers capable of driving 4 small or large motors, this allows for a dual motor configuration on the X, Y or Z Axis. The latest version of GRBL is pre-flashed onto the CNC Controller, you only have to simply wire up your machine to get it working!
New on the V3 is:
- Improved FTDI serial USB interface.
- Auxiliary PC fan header (12/24VDC Depending on supply voltage).
- 100% Input buffering on limit switches.
- Step/Dir breakout pads to add external drivers.
- Z-Probe pin now accessible from screw terminal.
- Plus many other tweaks.
- Integrated Motion Control, using the Atmel ATMega328 running at 16Mhz
- 4 Embedded DRV8825 Stepper Drivers with improved thermal management, capable of supplying 2.5A. Up to 1/32 micro stepping.
- 4th Driver can clone either the X,Y or Z Axis, or be used independently.
- 3 Mechanical Endstop inputs.
- Screw terminals or Terminal headers
- Power supplied from either an ATX PSU or 12-24V Power Supply
- 12V & 5V outputs for power accessories.
- Latest GRBL Pre-flashed
- G-Code From either the USB Port or Wireless (Xbee, WiFly, or RN42)
The CNC xPro controller comes pre-flashed with GRBL and interprets G-Code Commands. To send G-Code we recommended using either Universal G-Code Sender or Chilipeppr. Chilipeppr is especially good when combined with a Raspberry Pi running a JSON Server for wireless operation!
Please note that the CNC xPro is not compatible with Mach3
WARNING: GRBL Controller from www.zapmaker.org, has in some instances bricked the CNC xPro V3. So please avoid using this G-Code sender.
For the latest xPro V3, $4 needs to be set to 1, and $10 also needs to be set to 1.
For initial setup please refer to the CNC xPro GitHub Wiki page here:www.github.com/Spark-Concepts/xPRO/wiki
