Delta optical endstop problems

  • I have a Delta printer, optical endstops at the top.

    No matter if I have the endstops set high or low, they don't trigger the firmware.

    the lights operate on the board, (light goes on when endstop hit) but the machine properties in the settings tab do not show a change of endstop either on high or low.

    Where am I going wrong?

  • Make sure you have thick black flags. The lights can dim on the duet but not trigger. This was my experience.

  • Sensors were not producing high enough voltage. Changed resistor from 1k to 330ohm. (BIv25 printer)
