Raise3D Pro 2 Extruder Replacement Guide

Are you looking to enhance the performance of your Raise3D Pro 2 3D printer by replacing the extruder? Understanding the intricacies of this process is crucial for maintaining high-quality prints. In this guide, we will walk you through the steps involved in replacing the extruder nozzle on your Raise3D Pro 2, ensuring a smooth and efficient transition.

Let’s delve into the world of Raise3D Pro 2 extruder replacement and unlock the potential of your 3D printing endeavors.

How to Replace a 3D Printer Nozzle on Raise3D Pro 2

Replacing the extruder on your Raise3D Pro 2 3D printer is a straightforward process. Here are the steps to replace the extruder nozzle:

1. Power off the printer: Before starting any maintenance, ensure the printer is turned off to prevent accidents.

2. Remove the old nozzle:

   • Check if the hot end is covered with a silicone sleeve. If it is, remove the silicone sleeve from the hot end.
   • Use an 8mm socket wrench to unscrew the old nozzle from the heating block. Be gentle and avoid exerting force on the throat tube.
   • If there’s any remaining filament in the nozzle or heating block, preheat the hot end to melt the filament. Then use a spatula and tweezers to remove the melted filament.

3. Clear the hot end:

   • Insert a cleaning rod completely through the hot end to ensure the tube is clear of any blockages.

4. Install the new nozzle:

   • Screw the new nozzle into the heating block, leaving a visible gap between the nozzle and the heating block.
   • Hold the heating block and tighten the throat tube by rotating the heat sink. The nozzle should “catch” on the tube.
   • If the heat sink is loose on the throat tube, secure the fixing screw before tightening the throat tube.
   • Finally, tighten the nozzle completely using an 8mm socket wrench while maintaining the gap between the nozzle and the heating block.

5. Reattach the silicone sleeve:

   • If you have a silicone sock, adjust the heat sink so that it is flush with the bottom of the large cylinder.
   • If not, lie the hot end assembly on a flat surface, rotate the heat sink, and tighten it into place.

Common Extruder Issues

Extruder issues can impact the quality of your 3D prints. Let’s explore some common signs and how to address them:

1. Over-Extrusion:

   • Signs: Blemishes, blobs, stringing, and poor dimensional accuracy.
   • Causes: Incorrect settings (nozzle temperature, filament diameter, flow rate, or e-steps), wrong nozzle size, or filament type.
   • Fixes:
     • Adjust slicer settings: Lower temperature, match filament diameter, calibrate e-steps, or reduce flow rate.
     • Benefits: Improved print quality, reduced jams, and less filament waste.

2. Under-Extrusion:

   • Signs: Incomplete layers, thin layers, gaps, and structural weaknesses.
   • Causes: Dust, debris, moisture in filament, inaccurate diameter, air bubbles, poor storage, or clogs due to burnt plastic.
   • Fixes: Check filament quality, ensure accurate diameter, store properly, and maintain correct printing temperature.

3. Other Extrusion Problems:

   • Signs: Vibrating extruder motor, skipping steps, clicking sounds during printing, or lower print quality.
   • Causes: Various issues related to extrusion mechanics.
   • Fixes: Investigate motor issues, check for obstructions, and ensure proper assembly.

Steps to Replace Extruder on Raise3D Pro 2 Printer

Replacing the extruder on your Raise3D Pro 2 printer involves a few steps. Let’s walk through the process:

1. Power Off the Printer:
   Make sure the printer is turned off before proceeding with any disassembly.

2. Unloading Filament from the Extruder:

   • Access the “Utilities” tab on the printer screen.
   • Set the nozzle temperature to the proper unloading temperature (e.g., 215°C for PLA).
   • Select “Unload” to pre-extrude the remaining filament and withdraw it.
   • Gently pull out the filament from the extruder.

3. Position the Print Head for Easy Access:

   • Unlock the print head carrier from the “Utilities” tab.
   • Move the extruder to a position suitable for operation.

4. Removing the Left Extruder:

   • Turn off the printer and disconnect the power.
   • Release the red buckle and remove the interchangeable hot end from the printer.
   • Remove the back cover and unscrew the 7 screws (6 with a 2mm hex wrench and 1 with a 2.5mm hex wrench).
   • Pull out the left extruder motor cable and the hot end connecting cable.

5. Install the Replacement Extruder:

   • Align the replacement extruder with the slot and securely install it.
   • Tighten the 3 screws on the side of the left extruder using a 2.5mm hex wrench.

6. Reconnect Wires and Assemble:

   • Reconnect the extruder motor cable and the hot end connecting cable.
   • Securely mount the extruder board to the side of the print head.

Remember, these instructions are specific to the left extruder. If you need to replace the right extruder, follow similar steps for the right side. If you encounter any issues or need further assistance, consider reaching out to Raise3D’s support for personalized guidance

Step-by-Step Guide for Replacing the Right Extruder

Here’s a step-by-step guide for replacing the right extruder on your Raise3D Pro 2 3D printer:

1. Unload Filament from the Right Extruder:

   • Ensure that you’ve completed your printing task.
   • On the touchscreen, select the “Utilities” tab.
   • Set the nozzle temperature to an appropriate unloading temperature (e.g., 215°C for Raise3D PLA).
   • Choose “Unload,” and the nozzle will heat up.
   • When the target temperature is reached, select “Unload.”
   • The extruder will pre-extrude any remaining filament and start withdrawing it.
   • Depress the quick connector ring and remove the filament guide tube.
   • Gently assist in removing the filament completely from the extruder.

2. Position the Printhead:

   • In the “Utilities” tab, select “Stepper Motor Unlock.”
   • Carefully position the printhead for easy access.

3. Toggle to the Left Nozzle:

   • Still in the “Utilities” tab, select the “Left” L-nozzle icon.
   • The right-side extruder should move to the upper position, which is ideal for removal and installation.

4. Remove the Right Extruder:

   • Power off the printer and disconnect the power cable.
   • On the right interchangeable hot end, release the red buckle.
   • Hold the handle on the front of the interchangeable hot end and remove it from the printer.
   • Install the replacement right extruder, aligning the bearing with the slot.
   • Securely mount the extruder to the printhead.
   • Pass the right extruder cable through the empty slot on the device.
   • Pass the hot end connecting cable through the empty slot on the device below.
