Autoload filament not pulling through
Hi all
My filament will not autoload when i press the knob. However, if it choose to unload filament, the cogs move and the filament unloads fine. Is there something I need to check, clean or replace for this to work as it was before?
This is most likely a blockage.
Attempt to load flament. It will fail. Mark the filament at the point where it enters the extruder (sharpie) and unload.
Now offer the filament up against the extruder, aligning your mark, and you will see how far down the blockage is.
The block may be above the heatblock. Sometimes a fragment of filament can lodge here if your unloads are blobby at the tip - sometimes it's caused by a distorted PTFE tube. Either will need partial disassembly.
If the blockage is in the heat zone then loosen off the idler, heat the extruder and attempt to push filament through by hand - if this works then follow it up with a cold-pull and you should clear it.
Cheerio,
