So ive been printing some larger projects with my cr10s pro. And intermittently it seems the bowden gets ripped out from the extruder side causing filament to go all spagettie around the printer.
So settings wise this printer has mostly been printing pla and has completed a 60 hour print with the same spool of pla. Ive used the same slicer stock settings for the cr10s pro in prusaslicer and used the stock settings for prusament pla.
Currently my fix has been replace the bowden tube as it has cut marks in it from the push in fitting.
The push in fittings seem in good order, and ive never had this problem with my other printers. Of which i usually go with stock prusament settings.
Other than go direct drive, what ideas does the hive mind have for this.
If i had to guess it seems to be creating too much pressure behind the nozzle, and that coupling may be the weak spot. Could it be worth while looking into a different style of coupling or different hotend (its currently the stock creality one which has silly nozzle threads). I cant confirm the other times if ground up filament was an issue too, but judging from the scrap filament from this mess, it looks like there was a good bite out of it from the extruder.
I cant confirm if this issue has occured with capricorn tubeing, as currently ive installed some stuff i got in bulk from 3dpc.
Any ideas/suggestions are all appriciated.
