Technical Specifications

  • Supports 3 axis in Step\Direction method
  • Supports UniPolar Step Motors
  • Can work in either Full-Steps or Half-Steps for higher precision
  • Connects to the computer using the parallel port (LPT)
  • Complete optical isolation from the computer - protects the computer from possible CNC malfunctions.
  • Home and limit switches support for the 3 axes.
  • Header access to every free LPT input\output (can be used to enhance the CNC control by adding vacuum cleaner, lubricant
  • Maximal voltage: 55v
  • Maximal current (for each motor): 10A
  • Seperate control for each motor!
  • Maximum of 35,000 steps per second for each axis
  • Heat-Sink ready
  • Actively Ventilated package (fan)
  • Firmware upgradable
  • Supports 5,6,8 wired motors
  • Supported by Linux CNC (EMC2), Mach3, Kcam

CNC Controller Case

  • 3 "one way" connectors for easily connecting the stepper motors while preventing mistakes
  • DB-9 ("serial") connector for limit-switches input.
  • Emergency Stop Button (the red button in the corner) that completely shuts down the electricity. The button is lit (using a bright led) while the machine is ON.
  • Well ventilated case using a 60mm brushless fan.
  • DC (12v) connector
  • General bench-top power supply connectors for the motor's electricity.

Your CNC controller appears to be great. Will you be suppling it complete, as a kit, PCB and programmed chips.......?

Can you display prices and options on your web site asap please. Please include postage for Europe too......

regards

Andy
