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.

Hello,

Sorry for late reply.

I think this could be a problem with your hotend module.

Please check if the screws that secure the heater and thermocouple are tightened (in both hotends).

Also please check if your material didn’t get damp, does it make noise when being loaded?

Black materials tend to shorten the life of the hotends.

Also please check if your fan shrouds and fans are working properly.

Best Regards

Hi,

Here comes a late reply. The problem is in the clogged nozzle. After changing a new one, the printing quality is good.

Thanks for the help.
