  1. I'm new to 3d printing but I'm trying to learn as fast as I can. I have a prusa i3 clone and it uses cura software to slice and print. I'm having an issue where the machine will retract the filament ( and by retract I mean alot of retraction) and the soft filament hardens in the tube going to extruder head, causing a jam. I'm not sure what I'm doing wrong, but I tried to turn off retraction all together in the cura settings, but the machine still does it. Is there anther setting on the machine thats doing this? I've read that retraction helps with 'stringy' prints, but do I even need retractio

  3. No loading it isn't the issue, its when its already printing. The reason I know it gets stuck is that filament stops flowing and when I depress the lever to pull out the filament it doesn't move. I took apart the extruder and found that it's getting stuck in the screw tube going into the nozzle head. Is it possible the nozzle is clogged or something?
  4. Also one other issue I've just run into is that while trying to print, the filament will get stuck while being fed into the extruder nozzle guide pipe if that makes sense. Is there a way to fix this? I figured it must be something I'm doing wrong or don't know about.
  5. hey guys I'm a brand new rookie to 3d printing. Very excited to learn all the ins and out of it. I'm having some issues with printing right now. Here's a little background and my systems/hardware: -Alunar M505 printer (prusa i3 clone, cheap DIY printer to learn on) -Cura 3.1.0 software -painters tape print bed -1.75mm PLA filament After assembling the printer and doing my best to "zero-in" and calibrate the bed and all the axis, I've tired to print out a test print to see the quality/make sure I did everything right. Well here's the thing, I can't get the filament to stick to the print be
