Hotend Problem
Hello people, I'm new here in the forum and for 1 year in 3D printing.
I hope you can help me, I've been solving my problem for a month, but without success.
Basic data:
- Tronxy X3 Bowden extruder
- 0.4mm Nozzle
- Autodesk Fusion 360
- Cura 3.0.4
My problem is that after about 10-15min the hotend nothing more extruded.
And if I restart the printing without any change, no more filament comes out.
What I have done:
- With the original Hotend
- Nozzle Cleaning
- Throat Cleaning
Everything without success. Starts well, but after a few minutes less and less is extruded.
- Buy a new Hotend (Clone E3D V6) with Nozzle, different Throats, Heat block, Push Fitting and PTFE Tube
- Everything without success, exactly the same problem.
- tried different Throats with PTFE tube and and Full metal
- tried different filaments PLA, ABS, PP
- Because the filaments were 1 year old, I bought a new PLA filament.
- tried different temperatures from 190 ? C to 240 ? C
The problem is not the extruder, because if nothing else can be extruded, I try to push it by hand and it comes out very little or nothing at all. If I then clean the Nozzle or do a "cold pull", go it again for a few minutes.
I hope you can help me, because I've run out of ideas.
Edit:
Prints with retraction to 4.00 mm and speed 30mm/s
push through the hotend without nozzle
push through the hotend with nozzle
( nozzle cleaned shortly before )
1 Print with 220?C
Pictures from the first print
2 Print with 195?C ( 2 Print because 1 print was too hot for the Filament )
Pictures from the second print ( left 220?C; Right 195?C )
how that should look like
Before the problem started. I could print with 60mm`s without over or under extrusion with straight and sharp edges.
Likewise, the top layer was perfect.Last edited by Phunkstar; 11-04-2018 at 07:06 AM.
