I finally slowly got to the commissioning part of the construction. However before going ahead i turned on and wanted to check that all wires are well connected. Unfortunately i have noticed that if i try to move the axis, the motor moves in one direction and not the other, while the extruder do not move (but maybe because temp is too low). Any idea what is going on? I glanced at commissioning and it looks like it assumes I can use the LCD controls to do it, but it will be impossible if I do not understand what my problem is. For reference, I have a hybrid titan dual (modified, but this should to matter as electronics is the same).
