Weird top layer texture | 3D Printing | Page 1

My ender 3 neo (modded into a s1 pro with klipper) has a problem where half of the top layer has a really weird texture. The bottom layer is also weird under the weird part of the top layer. The weird texture is on the right of the print

It sounds like you may be experiencing issues with uneven extrusion or possibly a leveling problem. Here are a few troubleshooting steps you can try:

Check the Z-axis alignment and make sure it's consistent throughout the print.
Verify that your extruder is properly calibrated and not skipping steps during the print.
Ensure that your filament is properly loaded, dry, and not tangled.
Check your slicer settings, particularly for infill patterns and top layers.
Make sure your printer's belts are properly tensioned and not slipping.

If these steps don't resolve the issue, it may be helpful to share some pictures or videos of the print so others can better assist you.

The mods are:

#

Dual z screws

#

Sprite pro

#

X Linear rail

#

Klipper

#

Crazy ass hot end fan thing

#

(Taurus V5)

#

Has BL touch

#

The really old probably extremely wet filament might be the problem but I don’t know

The first image is your first layer? Your bed is very skewed in relation to your gantry. You're too high on one side, and too low on the other, which means that side on the top builds up material and causes that rough surface.

#

Tram your bed and also make sure your gantry is aligned properly. Dual Z, so it could be skewed.

#

After that, calibrate Esteps, and extrusion multiplier for that spool if you haven't already.

#

Also obligatory dry your filament it's good for you.

I did the automatic bed leveling before printing with the bl touch so that should have fixed that problem

Ok I see that now

#

ABL is just mesh compensation, it can only do so much, and also depends on how high resolution of a mesh you have.

#

You still want a decently trammed machine.

#

Mesh is 7x7

#

One side of the print is definitely thinner than the other

#

The linear rail is a little bit skewed

You've changed a lot, and you probably want to go over your entire machine and ensure it's square and sound, with a decent machinist square, as well as retram the bed.

Unskew it. \o/

How would I un skew the z screws

#

And would I need to do it every time I accidentally push the carriage down?

safe narwhal How would I un skew the z screws

The way my machine does it is just whack itself to the top of the frame till it skips steps some. And yeah, probably, that'll probably skew your gantry.

ok

#

Ofc, you want a nice square frame as well. Enders rarely are. My old ender needed shims to get it reasonably square.

a problem might be that the range for the bed mesh is 1.2
