Weird behavior after M112/M999



  • Hi,

    I'm having several issues since I upgraded to 1.19+1.
    most of them are disconnects while uploading gcode files. (WiFi signal strength -61dBm)

    Another issue I just encountered: I just powered the printer on and changed my G31 settings in both config-override and config. I did not accept to reset the duet.
    I was connected to the usb with pronsole and did M112/M999, here are the results after I connect again with pronsole

    here are the results after I connect with the web ui:

    another M999 in pronsole and everything is fine, it seems very weird and it's not the 1st time it happens to me.

    Thanks for your report. I will correct the error message in firmware 1.19.1. Looks like the Duet received some junk on one of its GCode input channels.
