Duet 2 Wifi randomly shutoff and won't power back on
Momentary push button with SSR connected to PS_ON
Last night I was leveling my bed and my printer randomly shutdown. I tried to power it back on but it wouldn't stay running. after extensive wiring troubleshooting I decided to start fresh and install a backup Duet 2 1.04 board, PSU, SSR, switch, and new wiring. Nothing else is connected to the board except VIN power and ground and the PS_ON to the SSR.
When I hold the momentary button down the green 3.3v, red 5v, blue VIN, red diag LED turns on. I was able to get it connected through USB and use Bossa to upload the firmware. The device shows in device manager as Duet 2 wifi.
I connected with YAT and configured the web server so I can now connect through the webpage but nothing works to get the board to power on and to run config.g
After updating the firmware through the web interface the Diag LED is no longer on.
For some reason the printer doesn't want to power on from M80
Printer is running but M80 does not work. I had to install a normal on off switch for it to stay powered on
@dhusolo, normally I would say that it sounds like the PS_ON mosfet has failed. But it's unlikely to have failed on 2 Duets, unless it's because of a fault in the PSU.
@dc42 agreed. Is there a work around where I can still use that function or another way to test?
@dc42 Strangely enough I moved from the 5V PS_ON pin to an open 3.3V endstop pin and it works now...
