Duet 2 Wifi shutdown immediately after restart



  • Hi all,
    i just end to build my printer, i'm using a regular 24v 500w psu, a ssr 25DA and a temporary 220v switch to allow auto shutdown.
    M81 is working fine, i put M80 at the start of config.g.
    Every time i chose to restart the board when config.g is saved, the board restarts but immediately the psu turns off.
    The PSU is set to 24.2v.
    Any suggestion?
    Thanks

    Can you show us your config.g and maybe a diagram of how you have things wired?

  • Please help me



  • Resetting the board has the same effect as M81 on the PS_ON pin, so that is expected behaviour even if not desired.

    You can move the PS_ON pin to GND while setting up the printer to work around it, and move it back to PS_ON when you need to turn the printer off from web.



  • You could try putting capacitor on SSR input.
