If you have tried calibrating the Mini and adjusting the Z-axis offset, but you are still having issues. For example, prints won’t stick to the print bed, or the tape on the printing bed has been scratched, we recommend following this guide to adjust your X-axis support.

---

Connect to a PC, open XYZware, and click on Printer monitor > Setup > Jog mode. Then click Home axes.

Check and make sure the Extruder module has returned to its home position.

---

Move Z-axis up by 10mm.

---

Manually move the extruder module to the right.

---

Open the black cover on the left-hand side of the machine.

---

Take the leveling tool supplied with the da Vinci Mini, and place it on the print bed under the X-axis support.

---

Unloosen the 4 screws manually, but do not take them off completely.

---

In Jog mode, move Z-axis downward by 1mm.

Repeat the above steps until the X-axis support and the leveling tool are flush.

---

Check that the leveling tool and X-axis support are in full-contact with each other, then tighten the 4 loosened screws.

---

Remove the leveling tool – X-axis adjustment complete.

Before trimming the guide tube of the da Vinci Mini, you need to unload the filament. Instructions for this can be found in the link below:

---

Remove the guide tube from the feed module.

Push down on the black ring on the feed tube grip and pull out the feed tube.

---

Remove the guide tube from the extruder module.

Push down on the black ring on the feed tube grip and pull out the feed tube.

---

Prepare the following:

• Feeding path cleaning wire
• Diagonal pliers
• Scissors

---

Insert the feeding path cleaning wire into the guide tube.

---

Use the pliers to cut the guide tube cleanly.

---

Remove the feeding path cleaning wire from the guide and reinstall the guide tube.

Note: If the guide tube is under 50cm, we recommend that you replace it.

---

During filament unloading, if the filament breaks off or gets stuck in the drive gears, you will need to clean the drive gears. Below is a detailed explanation on how to do this.

Push down on the black ring in guide tube connector and remove the guide tube from the feed module.

---

Open the feed module cover.

---

Unloosen the screws on both sides of the cover.

Note: do not remove them entirely from their sockets – you will be tightening them back up shortly.

---

Remove the cover protecting the motor.

---

Clean the left side idle roller and right side motor gear with the brush.

---

If the filament breaks off inside the feed module, or is stuck, push the release arm and remove the broken filament.

---

Reattach the cover protecting the motor, then reattach the screws.

---

Reattached the feed module cover.

Before cleaning the nozzle of the da Vinci Mini, you need to unload the filament. Instructions for this can be found in the link below:

Unload filament 

---

In the printer monitor panel, click Extruder > Clean Nozzle.

---

Click Start to begin the cleaning process.

---

After the extruder module has moved to the center of the print area, remove the guide tube from the extruder module.

To remove the guide tube, push down on the black ring around the guide tube connector. This will release the teeth that hold the tube in place.

After removing the tube-end, place the tube to one-side.

---

Insert the cleaning path feeding wire deep into the extruder – any remaining molten plastic should come out of the nozzle head.

---

Using needle nose pliers, hold the cleaning wire and insert it into the nozzle head.

Insert the cleaning wire at different angles to make sure that the nozzle is clean.

Caution: The nozzle head is hot, be careful when handling the extruder module.

---

Holding the extruder module with one hand, insert the cleaning path feeding wire again to remove any excess filament.

---

Reinsert the guide tube into the extruder module.

---

In XYZware, click Finish to complete Nozzle cleaning.
