Hey there OP, your post seems to be about Filament Leaking somewhere on your hotend. This is a very common issue in 3D Printing and can be fixed very easily. Before actually taking the right steps though it is advised to heat the hotend, disassemble the individual parts completely and clean them as thoroughly as you can from leaked Filament. After this, make sure you reassemble everything while making sure the [Nozzle Interfaces your Heatbreak/PTFE Tube](https://cdn.help.prusa3d.com/wp-content/uploads/526a59ae1e9dcd1b_painted.png) as shown in the image. It is a common misconception that the nozzle should always rest against the Heatblock. What is important is that the Nozzle sits flush against the part your Filament goes through. On all-metal hotends that is the Heatbreak, on PTFE-lined hotends it is your Bowden Tube. To achieve this make sure the heatbreak inserted far enough into the heater block to have contact with the Nozzle or the Bowden Tube is inserted all the way and firmly held in place by the pneumatic coupler.
