My CR6 keeps clogging, I have been unable to finish any pla print in weeks.
The issue seems to be associated to parts that need a fair amount of retraction. I have also installed a Capricorn tube, with no benefit.
I have also tried increasing the hotend temperature. Any suggestion?
A different filament, not newer neither better kept, allowed the print to be finished.
However there wasn't a real clog. I just changed the filament and try to extrude the filament and there were no issues.
I believe that the filament, a geeetech silk pla, got a little brittle and the oscillations of the spool in retraction intensive parts increase the probability that the extruder ruin the filament, stopping the extrusion.
I will be doing some test, printing a new holder.
@Gracy I have tried all the steps, not just once.
The weirdest thing that happens is the fact that I hear I little bang from the extruder, like a big missed step. Not sure if this is just the consequence or something in the extruder weakened overtime.
I have also tried replacing the original lock in the hotend with the one that comes with the capricorn tube, it went a little over, but I wasn't able to finish the model.
I will try with a different filament.

Hi, @guivo You can also check whether the nozzle temperature is 200℃, too low temperature will lead to clogging;
Check whether the nozzle fan is running normally, and it will cause a clog if it is not cooled in time;
After cleaning the nozzle and tube according to the tutorial, try to feed filament manually and check whether it is blocked.
@Gracy the filament is not brand new but it seems well kept, I'll try a different one to check.
Installing the Capricorn tube, I kept the original plastic holder, not sure this makes makes any difference.

@guivo 1. please refer to this video on nozzle and tube cleaning:
2.Please keep the filament clean and dry. If dust adheres to the consumables, dust accumulation will easily lead to nozzle clog during printing.
