Hardware_Description - Spark-Concepts/xPro-V5 GitHub Wiki

The CNC xPRO V5 is an easy to use high power motion controller for CNC machines. The CNC xPRO is capable of supporting a wide variety of CNC machines with up to 4 motor working independently or ganged (multiple motors working together to move one axis like the Workbee machines, also called dual drive, cloned, etc.). The CNC xPRO-V5 runs on a 32Bit processor and has integrated Wifi and Web Interface capabilities.

The xPRO V5 uses Trinamic stepper drivers to drive 4 high Power MOSFETs per axis and capable of driving motors up to 6 amps.

Specs:

  • 24v - 15 Amp Input Power Fuse
  • Built-in Heatsink & Temperature Controlled Cooling Fan

Motors

  • Control up to 4 coordinated axes (XYZA)
  • Each axis can have 1 or 2 motors each for a total of 8 motors
  • Dual motors axes can optionally auto square using a home switch and independent control for each motor.
  • Motor drivers can be dynamically assigned to axes, so a 4 motor XYZA controller could be converted to a XYYZ (dual motor Y axis) without any hardware changes.
  • Step rates up to 120,000 per/second.
  • Up to 1/256 Micro stepping (Defaulted to 1/8 for higher Torque).
  • Trinamic (SPI controlled) stepper motors are supported including StealthChop, CoolStep and StallGuard modes.
  • Sensorless homing can be used.

Peripherals

  • Limit/Homing Switches with debouncing
  • Up to 24v 5A switched output for coolant devices such as 24v DC pumps, solenoids, contactors, or Solid State Relays
  • Configurable Relay for generic use cases (Plasma trigger, Coolant Pumps, Spindle control, etc)
  • Configurable Macro input
  • Z Probe (XYZ)
  • Safety Door Switch

Spindles

  • PWM
  • RS485 Modus
  • DAC (analog voltage) 0-10V
  • Relay Based
  • RC type Brushless DC motors using low cost BESCs
  • Laser PWM with power/speed compensation
  • Easy to create custom spindles

Connectivity

  • USB/Serial
  • Bluetooth/Serial Creates a virtual serial port on your phone or PC. Standard serial port applications can use Bluetooth. WIFI
  • Creates its own access point or connects to yours.
  • Built in web server. The server has full featured CNC control app that will run on your phone or PC in a browser. No app required. Telnet sending of gcode
  • Push notifications (like...job done, get a text/email)
  • OTA (over the air) firmware upgrades.
  • SD card (Gcode can be saved, loaded, and run via WIFI)

Compatibility

The xPro-V5 is fully backward compatible with GRBL and can use all gcode senders.

Customizable

  • Easy to map pins to any functions.
  • Custom machines can be designed without touching the main code.
  • Custom initialization
  • Kinematics
  • Custom homing
  • Tool changer sequences
  • Button macros (run gcode sequence, etc.)
  • Custom end of Job sequence
  • RTOS Real time operating system allows background monitoring and control without affecting motion control performance
  • Fast boot
