Geeetech

I have a Geeetech i3 pro b which is only 4 weeks old. Build went smoothly and it printer some good items. Last week it started to fail as the extruded was found to be clicking. I have tried all the suggestions on the forum without success. On stripping the extruded down I found the marks as seen in the picture. Is this a manufacturing problem as I would have thought that the wheel should not touch the heat when filament is in place. Any suggestions please. I have ordered a replacement extruded and hot end assembly to see if this sorts the issue. Although as the printer is new is this a warranty issue?

Hi, can you provide the print quality picture？
from the picture can't see what happened.

Hi,

I was trying to print a Benchy. See attached. The print stars ok. After. A while usually about when it gets to start the cabin etc it stops laying down layers and extruded starts clicking. Sometimes the filament is stuck in the hot end and I have had to strip it to clean it out. On rebuild and test before printing filament flows ok when pushed by hand or driven by the motor. I have tried various temperature combinations. Last was bed 45 degrees and hot end 205 degrees C. As state I have previously printed good items see pictures. I bought the unit from Amazon so will return as faulty if cannot fixHope this helps. Dennis

Hi，I thought you would provide a printout with printing problems,
You can check the spring tension of your feeder,
Whether the extruder motor is running

Hi, the motor runs and then starts clicking, I have tried another motor and same happens. If I pause the print and pull the filament it is as the pictures Attached. If I cut it and re insert and continue with the print it works for a short period and then stops feeding again. Clicking noise. The gear has physical damage the teeth have a groove in them so to me looks like mechanical damage. I have measured the filament and this is shown in the pictures. Also I include the failed print which shows where it started to fail and not lay down enough filament. At the start it looks good to me. I have not changed any settings on the printer. I checked by printing a part that had been successful before and this failed the same way. I have tried adjusting the screw but nothing happens to improve the feed. I did not touch this between the successful prints and when it started to fail. Regard

Hi, It doesn't look right,
If the gear is defective,
You can contact your sales for replacement processing.
