In this article, we’ll take a closer look at the pulleys replacement process for the Raise3D Pro 3 printer and provide some tips on how to successfully complete the task. We’ll explain the tools and materials you’ll need, the steps to follow, and the common issues that can arise during the process. By the end of this article, you should have a better understanding of the pulleys replacement process and be able to replace your printer’s pulleys without any problems.

Identifying the Pulleys that Need Replacement

Before you start the pulleys replacement process, it is essential to identify which pulleys need to be replaced. To identify the pulleys, you need to check if they are worn, damaged, or misaligned. Here are some steps to follow while identifying pulleys that need replacement:

  • Check the pulleys and belts for wear and damage.
  • Check for chipped, cracked, or visibly worn teeth on the pulleys.
  • Make sure that the pulleys align correctly to prevent any further damage.
  • Inspect each pulley individually as some pulleys may wear out faster than others.

Once you have identified the pulleys that need to be replaced, you can order the replacement parts from the manufacturer’s website or other online retailers. Raise3D’s official website offers replacement parts for their printers, including pulleys, belts, and other components. You can also find compatible replacement parts from third-party retailers such as Amazon, Matterhackers, and TH3D Studio. However, it is essential to ensure that the replacement parts are compatible and of high quality to prevent any further damage to the printer.

Tools and Materials Required for the Replacement

To replace the pulleys on the Raise3D Pro 3 printer, you will need several tools and materials. Here are the items required for the pulleys replacement process:

Wrench Size will depend on the printer’s pulley size
Screwdriver Size will depend on the printer’s size

Lubricant General purpose machine oil or silicone-based lubricant

It is important to use the correct size wrench and screwdriver to prevent any further damage to the printer. Additionally, lubricants such as general-purpose machine oil or silicone-based lubricant should be used to ensure that the pulleys operate smoothly. It is essential to use compatible replacement parts from the manufacturer’s website or trusted third-party retailers to prevent any damage to the printer’s other components. Did you know that investing in quality replacement parts can save you money in the long run? Low-quality replacement parts may cause further damage to the printer, leading to more costly repairs or replacements in the future.

Removing the Old Pulleys

Before installing the new pulleys, it is important to remove the old ones carefully. Here are the steps you should follow to ensure a successful pulleys replacement process:

  • Disconnect the belts that are attached to the pulleys, and carefully remove the pulleys using a wrench or pliers.
  • Inspect the mounting holes for any damage or wear and tear, and repair if necessary.
  • Loosen the set screws that secure the pulleys onto the shaft using a screwdriver.
  • An alternative method is to use an applicable gear puller to remove the pulleys from shafts without causing damage to the belts or shaft.

It is vital to be gentle when removing the pulleys to prevent any damage to the printer’s components. If the pulleys are difficult to remove, applying a small amount of heat to the area for a few minutes can help loosen them. Keep in mind that excessive heat can damage the printer, so use this method with caution. It is recommended to follow the official Raise3D Pro 3 Pulleys Replacement Guide available on their website to ensure the correct removal of the pulleys.

Installing the New Pulleys

Once the old pulleys have been removed, it is time to install the new ones. Here are the steps you should follow to ensure a successful pulleys replacement process:

  • Lubricate the new pulleys to ensure they operate smoothly.
  • Align the new pulleys with the mounting holes.
  • Press the pulleys onto the shaft and tighten the set screws using a screwdriver.
  • Alternatively, you may attach the new pulleys using a pulley press installation tool to ensure even pressure distribution.
  • Re-connect the belts to the pulleys to complete the installation process.

It is crucial to align the new pulleys correctly to ensure the correct operation of the printer. Misaligned pulleys can cause the print head to move erratically and can affect the quality of the printed objects. It’s recommended to double-check the alignment of the pulleys before tightening the set screws. Raise3D offers a detailed guide on how to install and align pulleys for their printers, which can be found on their website. Additionally, If you have any doubts or queries, manufacturer’s customer support teams can help answer all your questions.

Testing the Pulleys

After replacing the raise3D Pro 3 pulleys of your Raise3D Pro 3 3D printer, it’s essential to run some tests to ensure that everything is working correctly. Here are some tests you can do:

  • Power up the printer and ensure that the print head moves smoothly in all directions.
  • Check for any unusual noise, such as grinding or slipping, which may point to alignment or belt tension issues.
  • Print a test object to check the quality of the printed output.
  • Inspect the pulleys and belt tension regularly to ensure they are in good condition.

If you notice any issues during testing, you should double-check the alignment of the pulleys and belt tension. If the issues persist, you may need to contact your printer’s manufacturer or a professional technician for further assistance. Don’t forget that proper maintenance is critical for the longevity of your printer. Raise3D offers a range of maintenance tools and replacement parts, including pulley and timing belts, available on Raise3D’s website. Additionally, conducting routine maintenance and keeping your printer clean can help prevent potential issues in the future.

How do I check the tension on my 3D printer belt?

Checking the tension on your 3D printer belt is an essential task that should be performed regularly. Improper tension can lead to faulty prints, unexpected layer shifting, and can wear down your printer faster. So, how do you check the tension on your 3D printer belt?

First, turn off your printer and remove the filament spool. You don’t want any accidental movements during the process. Locate the belt, which is usually located on the X-axis or Y-axis. The belt should be tight enough so that it doesn’t sag, but not so tight that it’s difficult to move the axis.

Next, using your fingers, gently push the belt in the middle. It should move around 1/4 of an inch if the tension is correct. If it moves too much or too little, it’s time to adjust the tension.

To adjust the tension, locate the tensioner. It’s usually a small screw that you can tighten or loosen. Tighten the screw if the belt is too loose and loosen it if the belt is too tight. Keep testing the belt tension until it’s perfect, using gentle finger pressure to see if the belt moves about 1/4 of an inch.

Once you are done, tighten the tensioner screw as much as possible to secure the belt’s tension. And there you have it, checking the tension on your 3D printer’s belt is easy and only takes a few minutes. Regularly checking the tension and performing maintenance on your printer can keep your printer operating in top condition, and you can enjoy your favorite prints with ease.


Replacing the pulleys on a Raise3D Pro 3 is a necessary process that helps extend the life of your printer. With the right tools, knowledge, and patience, you can successfully replace your printer’s pulleys and ensure its optimal performance. Remember to perform regular maintenance on your printer, including inspecting and replacing worn parts like the pulleys, to prevent any issues and extend your printer’s lifespan.

If you’re hesitant about replacing the pulleys yourself, consider seeking assistance from a professional technician. Furthermore, you can find various resources available online, like YouTube tutorials and online forums, that can guide you through the process. Ensure that you have adequate information about the task before starting, and always use appropriate tools.

In summary, replacing pulleys on a Raise3D Pro 3 is not as challenging as it may seem initially. The replacement process is quick and simple when done right. Remember, prolonged printing may produce wear and tear on machine components like the pulleys; hence, it’s essential to inspect and replace them when necessary. By doing so, you’ll maintain your printer’s optimal health and ensure it continues to function smoothly.
