LinuxCNC controls a large plasma cutter

Summary

Maker Works builds a rigid CNC plasma router with servo drives, gear reduction and LinuxCNC as an open machine control. The project cost about 8,000 US dollars. X and Y use NEMA 34 servo motors.

Ideas

  • Aluminium profiles form a precise machine frame.
  • Servo motors drive the X and Y axes.
  • LinuxCNC generates precisely timed motion commands.

Insights

  • Open control makes large workshop machines adaptable and repairable.
  • Mechanical rigidity and control together determine the quality of the cut.

Recommendations

  • Contain plasma interference electrically and spatially.
  • Test the emergency stop and limit switches before any cutting movements.

LinuxCNC gets an integrated CAM tool

Hackaday describes LinuxCNC-Features, which creates simple machining sequences, exports them as G-code and visualises them directly in LinuxCNC. At the time of the report, LinuxCNC-Features had been available for about two years. The tool supports milling and turning.

Linux controls a real 6502 processor

Hackaday shows how a BeagleBone loads, starts and operates a discrete 6502 as a remote processor from Linux via GPIO. The project uses a discrete 6502. An ARM-based BeagleBone serves as the host.
