Make sure the right side Heater Block Mount and Clamp screws are loose.

Make sure that the Liquefier Alignment Rod is straight. Roll the Rod along a flat
surface to check for bends. Straighten as necessary.

Caution: Use care when moving the Toggle Bar. Forcing the bar, or applying too
much pressure, will damage the Liquefier Alignment Rod and cause a
misalignment of the Liquefier Tubes with the filament path.
Note: Make sure that the Heater Block does not move while tightening the mount
screws.
