I have a Makergear M2 with dual extruders mounted together in the same printhead. As you can see the offset for extruder 2 is -31.1mm and Cura accounts for that correctly as I can't print on the far left of the bed with extruder 2.
Here's the rub, extruder 1 CAN print anywhere on the bed. Shouldn't disabling extruder 2 by unchecking the box shown below "disable" extruder 2 allowing me to utilize the entire bed?
