I have a creality ender 3 pro. I use creality pla+ filament. It breaks right at the Extruder. It breaks between the pulley and the gear on the stepper motor. it is the original setup from the factory. The only thing that i change was the hotend and that was a year ago. it looks like the filament is grind in half. It will work good for one print and then the next print it will break off. I check everything and it looks good. I even tighten the screw to make it tighter. thanks for the help i get.
Hi there…
I advice you to use a plastic container for the spool and some kind of tubing to cover the filament all the way from the box to the extruder to ensure it to be moisture free.

I think i got it fix. My tube that goes into the hot end was melted a little and i cut the end off and put it back together and seems to be working now. I am ordering more tubes from Amazon this week just to have them. So hopefully it is fix. Thanks for the help.
