Bad surface quality

The surface quality is really bad for this print, does anyone could give some suggestions on the problem?
Thanks!
The Z-Suite is 2.30.0.0 and firmware is 2.6.6, M300 Dual.

Hello,

Could you send me the zprojx and zcodex of the model?

Best Regards

Did you notice if your extruder bearing skips when loading/printing?

You could for sure try performing the extruder maintenance.

When was the last time you replaced the hotend module it could possibly be a problem with heating or extruder cable.

Do you have issues with other models/materials?

Best Regards

Hi,

Thanks for the reply. The hotend module has never been changed. This machine just work for 500h.
No issues with models are found.

Thanks.

You can try printing the ribbon test and send me the results.

But please position the models as on the photo.

Best Regards
