Kossel Clear Delta Arm Crash Sensor

Hi All

This simple hack uses some limit switches to monitor the arms on a delta printer. Should the print head ever crash for whatever reason, the printer would pause, instead of bashing the arms around for hours. Only had 2 crashes in 1.5 years, 1 i think was a power glitch, and the latest was the wires catching on the print itself. Fixed the wires by attaching them to one of the arms via rubber bands.

The switches hook in electrically, by simply passing the filament sensor signal through
