Hello,
I just builded a Prusa i3 from makerfarm. The Hobbed bolt is digging into filament always at the same spot (please refer to the picture) ,
I tried without results:

1. Adjust the idler bearing at different settings
2. lower the tempeture of the hot end
3. lower the speed in slic3r from 30 to 15




No matter what i do The hobbed bolt always digg the filament in exactly the same place,

Can you guys give me your advice?

Warm Regards

Emmanuel

Looks like your nozzle is blocked

that is an unusual amount of die swell on the end are you using 3mm feedstock or 1.75mm? it looks from the die swell that the hot end may be a 3mm? it looks like makerfarm only sells 3mm kits of this model.

Yup, I'd guess 1.75mm Filament in a 3mm Hotend.

you guys are genius, I got a 0.35 mm nozzle. I check the filament i got and it says 1.75 mm in the spool. They sent me the wrong filament ,because i am such a newbie i did not double check.

Thank you, i just order new filament, i will keep you updated
