Controls for the R1+
The CONTROLS tab is where you can physically control your printer through the software. Here you can preheat your extruder and heated print bed, and even adjust your print speed while printing.
While your printer is idle, you can use the movement controls on this panel to move the X, Y and Z axes. The extrude/retract motor movement keys help in loading and unloading filament as well. You can unlock the motors after a print job in order to move them around by hand if need be. Also, if you need to home any or all of your axes you can do it here as well.
Speed and Extrusion Control
If you need to adjust the speed at which your extruder is printing, under Tuning Adjustment, use the Speed Multiplier slider at the bottom of the screen. If you want to adjust the rate at which your printer is extruding filament use Extrusion Multiplying. Slide it left to slow it down and right to increase the speed or flow rate. (This will only work while printing.)
