Unable to extrude (new printer)
I am assembling 400 machine from ratrig standard kit and have yet to print. Motors and heaters and fans all work as expected. From Klipper screen, pressing the extrude button does not do anything
Steps: Start machine. hot end is set at 200deg C. Klipper "load filament" and the gears turn on LGX Lite. filament advances. Press extrude or prime blob and nothing is seen.
Retract and unload turn the extruder backwards and filament moves out of spool end of PTFE tubing.
What do i need to do? Do i need to take apart the whole eva toolhead? Can i do this without disconnecting the belts?

How far does the filament advance? You will need around 100mm from the extruder until extrusion comes out of the nozzle
If it doesn't advanced that much, the filament is probably getting stuck somewhere between the extruder and the nozzle
About 10-15 mm to load nozzle. Then nothing as it tries to extrude, just the gears clicking
Then the extruder is pushing it into something and it probably doesn't advance further
Sounds like I need to take it apart to find the obstruction.
I would take the extruder off and run it without it being on the toolhead
See if it does advance that way
And indeed check for any blockages
Will check in few hours when I get home
Good luck!
The inside PTFE got mangled and was not open enough for filament. Pulled it out and replaced the tube. Now works and extrudes filament. Thanks for help.
Nice! Good to hear extrusion is happening 🎉
