      Hi i have a problem with m221.
      If i send M221 D0 S108 and then M221 D0 i receive a message: Extrusion factor for extruder 0: 108% and thats ok.
      But if i open DWC or check PanelDue there will be 110% so it was rounded.
      If i try to change it with slider or buttons to 103 or something like that, it is changed to 100% so it is also rounded.

      I checked Object model, and there is the rounded value, but M221 D0 returns correct value.

      I prepared video from PanelDue

        @szendo thanks for reporting this. The reason is that RRF is only reporting the extrusion fraction to 2 significant digits to DWC and PanelDue. So they display the rounded value. The same applies to the M220 speed factor.

        I will change this to 3 significant digits in RRF 3.4.0 stable.
