Wanhao i3 extruder clicking/thumping noise

[rastoma]

I have a Wanhao Duplicator i3 that is making a clicking noise at the extruder. Most prints look very good even with this clicking… or it’s rather a thumping sound I guess.

I have replaced the brass gear with one with more teeth for better extrusion. But I had this thumping noise before the new gear. The filament is not slipping.

Other than being annoying, I can’t get 100% reliable prints and have a feeling what ever is causing the thumping is causing various print problems. Again more often than everything looks pretty good, but I have enough failures that it’s more than “it happens sometimes”.

Any suggestions?

Your extruder gear is slipping on the filament. It might be the quality of the filament or the temp you are set at. What type filament are you useing and do you have the all metal upgrade?

I have the same problem time to time, I discovered that it’s happening because bad wire connection of extruder motor. Check wirings. Good luck!

I think it more the temps your printing at. try first a good flush with prints set to 250 running ply then bring down to 10 deg higher than what you where printing at. All filaments require 3 things to be correct for 100% quality, heating, speed, cooling, a lot of people ignore cooling but can be very pronounced in different materials. sure you,ll find it

If it’s a new gear did you check that it got enough grease where it spins? Also you mean that have tried it but I think you can use a very tiny bit of vegetable oil to help you filament flow.

Usually that sound means the gear is grinding your filament.

Sounds like one or more of three things. Either e-steps is too high and its trying to over extrude, nozzle too close to the bed or, partially clogged nozzle
