Hello, I’m a longtime cura user and I’m trying to print some gears on my k1 using creality slicer. The gears are printing stuck together so I’m trying to use horizontal expansion settings to open up the tolerances. The problem I’m seeing is that no matter what values I put into horizontal expansion, The print is coming out the same. Is there some other setting thats preventing horizontal expansion from working?
Hello @joshua_O
Welcome to the Official Creality Forum 
How are you printing them so they are stuck together…?
Picture maybe so someone can get a better idea for suggestions…
I’m trying to print the planetary gears on this model → The Ultimate Propeller Launcher w/ 64x Gearbox by NikoKun - Thingiverse
If I was using cura, the horizontal expansion setting will put a larger gap between the gears, but in creality slicer, it’s not doing that.
I would recommend trying Creality Print instead of Creality Slicer as the Creality Print software was designed to be used with the K1 series printers.
You could also try using Orcaslicer as it has profiles for the K1 series and tends to be a more powerful and feature rich slicer.
Creality Print latest version V4.3.8.6984 isn’t working either. It doesn’t seem to be completely ignored - the horizontal value entered appears in the gcode, but it only seems to make a 3rd or 4th decimal place difference to x- an y- coordinates and feedrate, and no discernible difference to the print.

Hello, I have the same problem. I use other slicers, but the Creality one doesn’t matter what number I put in the horizontal expansion, positive or negative, it doesn’t change anything.
did you ever figure this out ? I started using the V3 KE and would like to keep using this slicer is at all possible because Im sending prints to it through the slicer. Yes I am sure there are other ways to do this blah blah but horizontal expansion is one of the 3/4 settings that i really only ever mess with. It was driving me nuts and I finally google and find this. Any ideas ???
I think I’m seeing the same issue here (with Creality Print). The K1 Max is my first 3d printer, and I’ve been wrestling with this for a few days (various little things I’m printing). In my case, I’m printing holes for parts to fit into (they don’t need to be precise fits, so drilling seems like overkill).
When I need to, I can work around it by tweaking the hole size to make it a bit bigger (holes are printing about .4mm too small), and that works of course, but it adds steps (and makes the drawings ‘wrong’) that I don’t like.
From my reading, the Horizontal Expansion seems to be the solution to this problem, but I’ve tried small (0.2 - 0.8mm) and large (1-2mm) values in my “Parameter Config” (like a profile) and they make no significant difference in the output results. I’ve tried both negative and positive values, since I’m really not sure which I should be using. I’m leaning toward negative, but I’ve seen no results to support either way 
Like OP, I’m kinda wondering if there’s some switch/value elsewhere that prevents the setting from having any effect.
I guess the answer will be to try another slicer 
I get it, there are better slicers available. I’m just enjoying the end-to-end integration I’m seeing right now. Too bad it’s not really totally working.
I’m gonna do a bit more testing, maybe try a print with a crazy value (100mm/-100) and see what happens, or do some gcode diffing.
What do people like that works well with the K1 max? Cura? Others?
