Bug report: DWC reports "Heater Fault" after fault cleared



  • After clearing a heater fault and getting everything working & printing normally, if I disconnect/reconnect DWC, I get this popup:
    0_1535998481202_Heater Fault.png
    Per the photo above, the printer's heaters are both active and working - there's no fault.

    I originally saw it inside Firefox, so to check if it was some stored state in Firefox, I disconnected, closed Firefox, and opened DWC in Microsoft Edge. I got the same erroneous message (the photo is actually from Edge). If I close the warning, everything works normally until there's another disconnect/reconnect or connection from a different browser or PC.

    It sounds like the firmware has lost track of the number of devices you have connected, so it still thinks there is a device connected that hasn't been sent the heater fault message.

    btw Duet Web Control 1.22.3 is now the recommended version to use with RRF 2.01.
