Key Differences Between Raise3D Pro 2 and Raise3D Pro 3

The Raise3D Pro 2 and Raise3D Pro 3 are both impressive 3D printers, but they have some key differences. Let’s delve into the comparison:

1. Changeable Hot Ends:

   • Pro 2: The Pro 2 features a fixed hot end design.
   • Pro 3: The Pro 3 introduces changeable hot ends, allowing users to swap out nozzles for different materials or nozzle sizes.

2. Flexible Build Plate:

   • Pro 2: The Pro 2 has a rigid build plate.
   • Pro 3: The Pro 3 boasts a flexible build plate, which simplifies print removal and minimizes the risk of damaging the build surface.

3. Redesigned Printhead:

   • Pro 2: The Pro 2’s printhead design remains unchanged.
   • Pro 3: The Pro 3 features a redesigned printhead, enhancing overall performance and reliability.

Replacing Y-Axis Bearings in Prusa i3 MK3S+

Replacing printer bearings can improve print quality and reduce noise. Let’s focus on the Y-axis bearings for the Original Prusa i3 MK3S+. Here’s a step-by-step guide:

1. Introduction:

   • This guide covers the replacement of Y-axis bearings.
   • All necessary parts are available in the Prusa3D e-shop. You’ll need to log in to access the spare parts section.

2. Tools Needed:

   • Prepare a 2.5mm Allen key (ball-end recommended).

3. Preparing the Printer:

   • Remove the steel sheet from the printer.
   • Press the LCD knob for 1 second, then rotate it to move the Z-axis all the way up.
   • Ensure the printer is cooled to room temperature and turn it off.

4. Removing the Y-Axis Belt:

   • Carefully turn the printer on its PSU side.
   • Locate the Y-belt tensioner at the bottom of the Y-carriage.
   • Release the long screw joining the belt tensioner and belt holder.
   • Remove the tensioner with the belt from the Y-carriage.

5. Removing the Y-Belt Tensioner:

   • Unscrew the y-belt tensioner.
   • Take the free end of the belt and guide it through the y-belt idler out from the printer.

6. Removing the Heatbed:

   • Place the printer back on its feet.
   • Release all nine screws from the heatbed.
   • Set the heatbed aside on a clean surface.
   • Remove all nine heatbed spacers from the Y-carriage. Keep them safe; they’re essential!

7. Removing the Y-Carriage:

   • Release the screw on the top of each y-rod holder.
   • Remove four screws from the front plate.
   • Turn the printer so that the Y-axis motor faces you.
   • Repeat the process for the rear plate.

8. Disassembling the Y-Carriage:

   • Place the Y-carriage with the top surface facing down.
   • Remove all four y-rod holders from the smooth rods.
   • Pull the smooth rods out of the bearings (direction doesn’t matter).
   • Release the screws on the bearing clip and remove the bearing and clip from the Y-carriage.

9. New Bearings: Parts Preparation:

   • Prepare three new linear bearings.
   • Use paper towels to wipe oil and grease from the bearing surfaces.

Testing and Verifying New Bearings in Your 3D Printer

After replacing the bearings in your 3D printer, it’s essential to test whether the replacement was successful. Here are some steps you can follow to verify the functionality of the new bearings:

1. Visual Inspection:

   • Clean the bearings thoroughly.
   • Examine the condition of the bearing raceways and external surfaces.
   • Check for any cage wear, increased internal clearance, or degradation of tolerances.
   • Look for possible damage or other abnormalities.
   • Determine if the bearing can be reused.

2. Functional Test:

   • Perform a test print to observe the printer’s behavior.
   • Pay attention to the smoothness of movements in the X, Y, and Z axes.
   • Check for any wobbling or irregularities during printing.
   • If there was a specific issue before bearing replacement (such as noise, vibration, or uneven prints), compare the before and after performance.

3. Additional Considerations:

   • Ensure that the belts are properly tensioned and not slipping.
   • Tighten any loose screws related to the bearings.
   • Verify the alignment of components like pulleys and lead screws.
   • Use calibration prints to assess overall printer performance.

In conclusion, the bearings replacement process for your Raise3D Pro 2 printer is essential for maintaining optimal functionality and print quality. By carefully following the outlined steps and handling the components with care, you can effectively replace the bearings and prolong the life of your printer.
