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
what slicer are you using ?
Sounds like a gcode issue.
I'm using Cura. I am going to reluctantly dive into the G-Code and find this flipping error as it is all that it can be.
Hi
Just for reference, how many steps per mm is Marlin set up for?
Bob
X = 99.652,
Y = 93.894,
Z = 406.7484,
E = 97.2575
X and Y are perfect within 0.01mm
Extruder is spot on
Its just when changing resolution i get this issue
G-Code on a Friday im so cool
Hi
So you should get a bit over 80 steps at a Z of 0.2 mm. You are way away from any sort of rounding, micro step, or binary boundary issue at that point.

mattbatt84 - what do you see when you do a layer-by-layer review of the print in a gcode viewer? Some slicers have one built-in, or a popular one is available at gcode.ws
If the viewer doesn't show the entire height of the print as you expect, you know the issue is in the slicer.
EDIT: It's always a good idea to look the gcode in a viewer when a print isn't coming out as expected. Slicers have limitations on what they will command a printer to do. For example, if your print involves very thin walls, you could have a combination of slicer settings (maybe layer height, nozzle size, extrusion width) that causes the slicer to think it can't print them. Unfortunately, you get no warning in these cases - the slicer just ignores that part of your object and provides no gcode for it. If nothing else, checking the gcode in a viewer is at least a quick and easy thing to do.
