HXCNC-4A engraving machine control board is an integrated control system specially designed for small desktop engraving machines/3D printers/laser engraving machines/mechanical arms. It consists of a high-performance core board with FPGA-ARM architecture and a backplane with rich peripherals including five high-voltage drives. It supports five-axis linkage and arbitrary curve interpolation, as well as the Liberoll motion system with G+ multi-channel programming (multi-threaded) features.
The following hardware resources are onboard:
5 stepper motor drivers, each with a maximum current of 2.5A, supports 42 and 57 series stepper motors.
Onboard voltage regulator output, 5.3V-12.5V, adjusted by program, can drive external servos or other modules.
5V and 3.3V fixed power output.
Spindle PWM driver – 12A MAX.
Heat bed PWM driver – 12A MAX.
Digital servo connection port (universal serial port) X1.
4 Output channels to the external drivers.
Voice broadcast, directly connected to a 1.5W speaker.
Bluetooth interface.
Parallel LCD interface.
Travel switch input interface X5.
General ADC input X2 and GPIO X2.
Temperature sensor input X3.
Universal driver output (1A MAX) X4.
Remote control interface (universal serial port) X1.
SD card socket.
U Disk socket (USB OTG).
USB interface.
3 user buttons.
ARM CortexM4, Spartan3 FPGA, SRAM, online USB firmware update.
Features of HXCNC-4A:
It can be configured as a five-axis engraving machine XYZAB controller, or a 3D printer XYZE0E1 or a robotic arm controller, or used for a laser engraving machine, etc.
Rich on-board hardware resources.
Arbitrary space curve linkage and IO operations, with precise synchronization mechanism and predictive interpolation capabilities.
Powerful programming ability, support G+ system and MCC integrated development environment.
Super fast (>500KHz when four axis linkage, >5MHz when single move).
