      Why does the direct filament switch over DWC
      0_1542332669445_Change Filament.jpg
      fail with this error:
      Error: M701: Unload the current filament before you attempt to load another one

      When I first unload and then load it works

      Here are my macros

        I still could not find a solution?

        DWC sends the following code:

        T0
        M702
        M701 S"GreenTEC black"
        M703
        

        After unloading comes this error:
        Error: M701: Unload the current filament before you attempt to load another one

        Does nobody else have a problem with that? (Affects only the direct filament change via DWC)

          Chrishamm is the expert on both filament management and DWC, so I have asked him to reply.

            To me it looks like M702 completes before it is actually finished, so M701 is called out-of-order which generates this message. We will investigate why this is happening.
