My son was gifted a ender 3. We finally got x y and z running smooth.
The extender and hot end are directly connected.
Now when we use pronterface and hit extrude it runs smooth.
When we try and run a test print it spits out an initial line/glob then stops extruding and when we take it apart we find a knot or kink that looks warmed up at the top of the ptfe tube.
Thanks in advance
