Uneven Layer Lines?

[sand lava]

Just recently got my new CR 10 Smart Pro. Got a perfect first layer but the print has uneven layer lines? In the photo, you can see the different shades resulting from the layer lines. Any fixes?

Usually it has to do with the hardware of the printer. Any disturbances on the lead screw(s) and you’ll get variation. Loose gantry, too. But printing slower can also help

[sand lava]

@molten roost none that I know of? Any way to know which specific things to check?

I'm printing at 50 so it's on the slow side

[molten roost]

You probably won’t even notice the issue. Just a thorough cleaning and reassembly

[sand lava]

which parts should i disassemeble and clean?

cuz it's pretty much brand new

[molten roost]

Oh it could also be filament variation, while we’re at it. If the diameter isn’t consistent this can happen

I would pay particular attention to everything touching the lead screw, tho

[sand lava]

Hm this filament on the ender 3 s1 and it came out flawless

the leadscrew as in the two z bars that the extruder rides on right?

[molten roost]

Yeah, the greased screws

[sand lava]

idk what to go about troubleshooting this

every print has come out with these uneven layerlines

[molten roost]

Also idk how this is on that particular printer, but if there’s a brass bushing around the lead screw on the gantry, sometimes loosening it can help

Actually its not a bushing its threaded lol, mb

[sand lava]

lemme send a photo

This is on both my z screws

[molten roost]

Yeah are those two little screws with locknuts tight?

[sand lava]

Lemme give it a nudge

Yeah they seem tight

[molten roost]

Loosen them all half a turn

So the fitting can move a little

[sand lava]

Loosen these right?

[molten roost]

Yeah

Srry im at work lol

[sand lava]

yeah no worries

it still doesn't seem to fix ti
