      hello everyone !
      i have 2 duet boards one on a delta and one on a certesian, driver 3 blew on the cartesian, i tried taking unused driver 4 from the delta board and all went well desoldering no shorts etc, but unfortunatly now driver 4 reports short to ground/over temp, and even when i disabling driver 4 with m569 p4 r-1 but that only stops the short/overtemp message, still unable to move with the board saying motor phase A may be disconnected reported by driver(s) 0 1 2 of course i checked the cables with no issues, sooo do i need to solder driver 4 back where it was ? can't the duet function with only 4 drivers ? does it need to be soldered because it's powering the other 4 drivers ? thanks !

        @gz try firmware version 3.4

        [Duet 2] If a TMC2660 driver was removed from the Duet or Duex then none of the TMC2660 drivers would start up
