Extruder Gearbox is the mechanical part of an 3D printer

Extruder Gearbox is the mechanical part of an 3D printer that translates commands from the computer into movement of the print head. In most modern 3D printers, this is usually accomplished by using gears and motors.

The extruder is the part of the printer that moves the filament and builds objects.

Common Extruder problems include damaged gears or belts and clogged print heads,

But the material you use can also be a culprit. For example, if your printer’s extruder is made of plastic and has been damaged in some way, it’s possible that any number of things will cause problems:

• Clogged print heads – If your extruder gearbox isn’t properly cleaned out after each print job, bits of filament can accumulate inside the machine and make it difficult or impossible to remove them. This causes clogging in the extruder mechanism itself—which means that even if everything else works fine (like gears), none will move freely enough to push filament into position before it reaches its destination at the end of each stroke.
• Damaged gears – A similar problem occurs if there are worn-out teeth on one or more gears inside this part of a 3D printer’s overall assembly line—and we’re not talking about just any old wear here; these kinds of damage requires serious attention from someone who knows what they’re doing!

All Extruder parts are replaceable, but replacements are pricey, so it helps to learn how to repair them on your own.

All Extruder parts are replaceable, but replacements are pricey, so it helps to learn how to repair them on your own.

This guide will teach you how to fix your extruder gearbox with the help of some simple tools and common materials that you can find in any hardware store or online retailer.

It’s important to know what you’re doing if you’re going to be fixing anything more complicated than a broken belt or motor mount (which we’ll get into later).

If there’s no one around who knows how this works exactly—or if they don’t have time/money/energy/etc., then learning how yourself makes sense as well!

Clean the extruder assembly before replacing a part.

• Make sure the extruder is free of debris.
• Remove any loose parts.
• Clean the extruder assembly, including:
• The print head (the actual inkjet printing mechanism) and its associated bearings and gears; it may be necessary to remove them from their mountings in order to access them more easily when cleaning.
  
  A small amount of lubricant such as white lithium grease can help reduce friction between moving parts and make for easier removal later on during maintenance procedures if needed; however, do not use petroleum-based products such as WD40 or other oils because these will contaminate sensitive electronics inside your printer! If you don’t have access to any alternative solutions then applying some heat from an oven mitt should do just fine too—just remember not too hot though!

Inspect all the gears and belt for wear, cuts and abrasions.

Inspect all the gears and belt for wear, cuts and abrasions. Check for broken or damaged parts, missing or damaged parts, loose or broken parts and missing or damaged belts. Make sure that your extruder gearbox is not leaking oil into your main gearbox. If it is leaking oil, you should get it repaired as soon as possible!

Be especially careful to check the drive gear that goes between the motor and gears on the extruder assembly.

Be especially careful to check the drive gear that goes between the motor and gears on the extruder assembly. If this is cracked or worn out, replacement is definitely in order. Use a dab of super glue to ensure that it stays put when you replace it. Note which side leads to which part of the machine for future repairs or replacements

Replacing parts doesn’t have to be expensive or difficult

Replacing parts doesn’t have to be expensive or difficult. At least, not if you know what to look for and how to buy them. In this guide, we’ll cover all of the different types of replacement parts available for your printer and when it’s best to replace them.
