      I added on a Duex5 so I could do independent Z-axis bedleveling.

      While doing that, somehow I removed the voltage setting for Extruder.

      When I went to do extrude movements, I got a warning that the stepper wiring appeared disconnected.

      I spent a bit of time tracing my wiring, making sure nothing was wrong before I noticed the M906 lacked the usual E600 setting I use.

          Steps to reproduce:

          1. In config.g, remove the EXXX setting from the M906 line.
          2. Restart
          3. Heat hotend until extruder controls unlock.
          4. Retract hotend.

          Following message appears:

          This error does not appear if I remove the X or Y settings from the M906 line

            Thanks. The issue is that if the motor current is set to zero then the "motor disconnected" warning may be triggered. In a future firmware revision I'll set a minimum motor current for the warning to be active.

              How about a warning that they are trying to use a motor with no current defined?
