Red Light On Boot

A red light as soon as the feeder is connected to power means that the feeder was unable to find a slot.

  • Check the spring pins and ensure that they're all straight and extended the same length.
  • Try reseating the feeder a couple times. In rare instances, just the angle/way of putting dropping the feeder down can cause power to come up before the 1-Wire pin is connected.
  • Try moving the feeder to a different slot. Does it still turn red?
    • If so, it's probably an issue with the feeder.
      • Check the spring pins on the feeder PCB. Are they all straight and the same length? Gently adjust them with tweezers if need be.
    • If not, it's an issue with the slot.
      • Check the pads of the slot. Are they clean and free of debris? Power off your machine and wipe them clean, then try again.

Red Light After Feed

A red light after attempting to feed with either the buttons or through OpenPnP means that feeding failed. It can take a few seconds for the light to come on after commanding the feed.

  • Try feeding the feeder using the forward button with no tape loaded. Does the red light still come on?
