I have two similar parts (in size) and each one is small enough to have their own side of the bed. I have Cura setup so each part has it’s own extruder. If I select Dual mode on the printer, I am guessing both parts can’t really print at the same time because the extruders share the same X axis rail even though the parts have the same footprint. Am I missing an opportunity to increase productivity?
You are looking for the copy mode. It is intended to print identical objects in parallel.
The dual mode will print the two objects sequentially by switching extruders layer after layer.
