Cura 2.6.52 manual Z move

I notice that the Z axis will not move if the step size is less than 1mm. Is this normal or a bug? I was trying to use for a feeler gauge measurement between nozzle and build plate…need small steps and it would be convenient to be able to type in small numbers.

What value are you trying to use for your movement? I just tried a .1 mm movement command using Cura 2.6.66 and was successful. Give that a shot and see if it works for you!
