Panel Due 5i USB vs Control Board Power Anomoly

  • When I conncet my Panel Due 5i up via a USB Power and not have the Printer on all seems good. However when I let my Printer (Ender 3 with DUET 2 Maestro) power it the touchscreen goes non-functional, i have restarted the printer numerous time and a couple times the panel responds to touch but for the most part it doesnt. Again if powered by external 5 volt USB Source only all is good. Is there something I can check in order to resolve this issue?

  • @bfpa40 I recently had my PanelDue become touch unresponsive, but not everywhere on the LCD. I had to reroute the main 4 wire cable to a different position. Looks like there is some interference it doesn't like.

  • try a ferrite bead at the end of the 5V cable? you can buy cheap ones that just clamp on to the cable, super easy.


Looks like your connection to Duet3D was lost, please wait while we try to reconnect.
