AI Help

It looks like you are experiencing Z-axis banding artifacts in your prints. This issue can be caused by an inconsistency in the Z-axis movement, resulting in visible bands on the print surface.

Here are some steps you can take to troubleshoot and fix this issue:

  1. Check the Z-axis lead screw and ensure it is properly lubricated and free from any debris.
  2. Make sure the Z-axis motor and coupler are securely attached and aligned.
  3. Check the Z-axis stepper motor driver voltage to ensure it is properly calibrated.
  4. Verify that the Z-axis steps per mm are correctly set in your printer's firmware.
  5. Consider upgrading to a stiffer Z-axis coupler or adding a Z-axis stabilizer bracket to reduce wobble.

Implementing these steps should help you resolve the Z-axis banding artifacts in your prints.

if u need more information about anything, printer, filament etc, i would be willing to say it to you, if its helps to solve this, i would be thankful

your case looks like ringing paired with underextrusion. what speeds do you print with?

#

@ripe gate also does your ender have direct drive or still bowden extruder?

ripe gate
#

it has direct drive, and for this calibarations test im printing at 90 mm/s

#

the steps of the extruder are calibrated,when i put 100mm to print, it prints exactly 100 mm, and i just calibrated the flow for this filament, its brand new.

#

i can make some photos of my printer so you can see the hardware more or less.

stoic spade
#

have you tried printing slower just to make sure?

#

also do the y axis wall look good? cant tell from the picture

ripe gate
#

bouth axys are affected, and yes i have tried printing slower, and the problem still there, idk why, could be a very high presure advance¿

stoic spade
ripe gate
#

yes, its worst, th problem start even earlyer

stoic spade
#

okay, that almost sounds like extruder gear grinding on the filament or the filament has inconsistent diameter across the spool when printing

ripe gate
#

how could i fix that? the extruder is a bmg bondtech, and its actually really tight

stoic spade
ripe gate
#

yes i tried two, one from creality and this one that is from smartfill

#

i just finished the same print, tuning some things from the prfile, and at least it doesnt explode

stoic spade
#

the creality one printed just fine?

I tought it could be moisture, due to the water boiling inside the filament that could be popping like bubbles, generating that holes, so i changed the filament to this new one, but now i see that is like a pattern or something like that, idk what can i try next.

stoic spade
#

what slower speed did you testprint?

ripe gate
#

60 for interior perimeter 30 for exteerioir perimeters, nothing incredible, and i would say that this velocity is actually slow af
