I understand your answer. First of all, i have a z motor which has precission of 0.0002mm and also, i have removed the extruder and the filament as i would be using this 3d printer as a x, y and z stage for a different project where i need the z to be 0.0002mm.
According to what you said in the answer, i would set the layer height at 0.05mm in cura and then generate the gcode.
Then edit the gcode and divide every z value by 250.
First of all, the gcode wouldnt be increasing the number of coordinates for printing after i divide the z value by 250. Also, is there a program which can do this as manually replacing all the z values will take a lot of time!
