Features

• Connected via USB to the CNC machine (LinuxCNC driver available).
• Up to 6 linear and 3 angular axes.
• Continuous or incremental jogging via buttons.
• Incremental jogging via torque encoder.
• Configurable feed override potentiometer.
• Master spindle control.
• Motion-halt button (soft-estop).
• Configurable twohand (deadman) switch.
• Displaying of machine state on the LCD (axis position, feed, etc...).
• Easily configurable via LinuxCNC HAL file.
• Easily extensible (completely open source under libre license).
• Firmware update via USB.

Prerequisites

• The LinuxCNC HAL driver requires LinuxCNC 2.5.0(-pre) or later.
• USB-2.0 or USB-3.0 port on the CNC controller computer.

FAQ

• Q: Why isn't there a real emergency stop switch?
  A: A real emergency stop switch cannot be implemented via USB. A real estop would require an additional hardware wire to the CNC machine's motion controller. However, there is a software motion-stop switch, which stops all machine motion within the constraints of USB and userspace HAL component latencies.
• Q: Do you sell the hardware or parts of it?
  A: I'm sorry, I don't. But all drawings and schematics are free and can be found in the .tar archive. Feel free to contact me on any questions.
