Adjusting the Drive Gear Clamp Distance¶
The drive gear clamp distance is adjustable to accommodate different types of filaments. Rotate the Limit Screw counterclockwise (toward the marked "(-)") to decrease distance or increase clamping pressure, which is ideal for hard filament, or clockwise (toward the marked "(+)") to increase distance to decrease pressure, ideal for softer materials.
Note: Avoid forcing the screw beyond its stopping point to prevent damage to the extruder.
