If you own a Funmatte HT 3D printer, whether it’s the enhanced version or the non-enhanced one, at some point, you might need to replace the extruder motor. This guide will walk you through the process step by step, so you can keep your 3D printer in top shape.
Tools You’ll Need
Before we begin, make sure you have the necessary tools at hand:
- A 2.5mm Allen key
- A 3mm Allen key (included in your kit)
Step 1: Loosen the Tensioner
Start with the 3mm Allen key to loosen the tensioner. This will make it easier to work with the extruder motor.
Step 2: Remove the Arm and Spring
Use the 2.5mm Allen key to remove the upper left-hand bolt that holds the arm in place. Be careful when you remove it, as it’s spring-loaded. Once the arm is off, remember to catch the spring. Set the arm, spring, nut, and bolt aside as a single piece.
Step 3: Remove the Motor Bracket
Switch back to the 2.5mm Allen key and move to the upper right bolt. If it’s been sitting for a while, there might be some tension. Once it’s removed, there’s nothing behind it. The two bolts at the bottom are the last ones holding the motor in place. Remove these two lower bolts to take the bracket off as well.
Step 4: Disconnect the Motor
Now, use the 3mm Allen key to remove the two lower bolts. This will give you access to a brass nut that you can clean. Make sure to disconnect the motor from the Power Distribution board, but remember to turn off the printer first. Gently pull the motor’s cables and feed them around to avoid damaging other wires. The motor is now free.
Step 5: Reassembly
Reconnecting the extruder motor is a reverse process of what we’ve done so far. Here’s how you do it:
– Reconnect the bottom of the front bracket using the 3mm Allen key.
– Use two longer M3 bolts with 2.5mm Allen key to secure the bottom of the stepper motor in place. Tighten them gradually, ensuring it’s even against the bracket.
– Secure the upper right side with a smaller M3 bolt.
Now, comes the trickiest part – placing the spring. Make sure the tensioner screw is loose. Hold the right side of the spring and push it until it’s properly seated. Once it’s in place, tighten the tensioner screw.
Check the alignment to ensure everything is properly set up. Once that’s done, plug the motor back in.
Final Thoughts
And there you have it! You’ve successfully uninstalled and reinstalled the extruder motor on your Funmatte HT 3D printer. If you have any questions or need further assistance, don’t hesitate to reach out. Happy 3D printing!
