Good day to you all. Strange issue with my build. When I print a cube 20mm on 0.3 resolution it prints perfectly.
If I change the resolution 0.2 the z axis does not move. I keep my hand on the lead screw to see if I can feel it move and it does not. This is the same for 0.1 resolution
Does anybody have any ideas.


I am using a CTC duel coveted to Ramps 1.4 marlin
