Extruder

Grinding: One Side Keeps Grinding.

Problem

Only left or right side of my extruder keeps stripping when extruding.

Solution

Wall-E may be tightened, in a skewed position.

Make sure both ports have filament inserted.

Loosen all three M4 screws.

Look for a shift in the Wall-E position, when loosening. The Wall-E should shift into its natural position, if not already all there.

Lightly tighten the all M4 screws.

Extrude again for 400 mm (minimum). Look for a grinding.

If still skipping, continue reading.

There may be artifacts or clogging in your filament path.

Remove the Wall-E. Follow the Uninstall Extruder guide.

Remove the plastic insert: K'Tana or Compound.

Look for artifacts.

If it's a clog, follow the Unclogging Nozzle guide.

Skipping: No Extrusion. All Skipping.

I hit extrude. Only one side extrudes.

Solution

There may be artifacts in your filament path.
