      @dc42 - would it be possible to modify the firmware to set the idle factor per axis? As you saw with our printers, the z-axis is belt driven and requires a high idle percentage to remain stationary where the other axes do not. Thanks

      edit great to meet you, btw!

        M906 line for each axis with I value is what I do

          @tecno I just re-tested to make sure it wasn't that simple.. that appears to set the idle factor to the value in the last M906. Thanks

            I have to check and see the behaviour on my printers. Interesting....

              You are so right, missed that one. M906 line can only have one I value. I hope we can get a solution for this.

                @oozebot I believe it's in the list to look at. It's currently only a single value for all

                  @jay_s_uk correct, I plan to support per-axis idle current percentage in RRF 3.5.
