Hi,
It will be cool to have an option of "on Demand layer Height" the basic idea is when you have to print somethink that does not need much quality in some parts and in other yes. like a box. during the printer is doing the wall or the base it can make thiker layers like 0.3 0.4 etc. but when it comes to parts that need hi resolution itmakes thiner the layer to example 0.2 . so you can print "fast" in the simple shape aparts and get acurate when you have bends or somethink like that.
