Y Axis V Wheel Replacement

Fault Description:

1. Y-axis abnormal noise.

2. Layer shift in the Y-axis direction during model printing.

3. V-wheel deformation, flat spots, V-wheel peeling, and shedding.

 

Method of Replacement:

1. Remove Printing Platform:

   1. Remove the PEI board.

   2. Use an H2.5 hex wrench to loosen the four bolts fixed to the print platform.

Remove Aluminum-Based Printing Platform:

• Remove the aluminum-based printing platform.

Remove Y-Axis Belt Tensioners:

• Use an H2.5 wrench to loosen each of the two Y-axis belt tensioners.

• Remove the belt with the copper sleeve at the rear end (near the belt tensioners).

 

Remove Belt Tensioners:

• Remove 2 belt tensioners.

• Use an H3.0 wrench to loosen the belt tensioners and remove the belt.

1. Remove Bottom Shell End Cap:

   1. Use an H2.0 wrench to unscrew the 2 bolts at the bottom of the M5 rear end and remove the bottom shell end cap.

2. Remove Support Bracket:

   1. Place the aluminum-based platform at the rear end of the M5 and remove the support bracket from the M5.

3. Replace V-Wheels:

   1. Use an M8 wrench and the H3.0 hex wrench to twist off the four V-wheels respectively.

   2. To replace the four V-wheels, use an M8 wrench and H3.0 hex wrench, which will be installed on the support bracket.

4. Reinstall Support Bracket:

   1. Slowly push the support bracket into the M5 Y-axis slot and slowly pull out the lower belt.

5. Reinstall Belt Tensioners:

   1. Install the pulled-out belt into the 2 belt tensioners using an H3.0 wrench.

   2. Place the belt tensioner into the Y-axis card slot and clip one end of the belt copper sleeve into the support bracket.

6. Adjust Belt Tension:

   1. Use an H2.5 wrench to fix the belt tensioner and adjust the tightness of the two Y-axis belts.

7. Check for Shaking or Noise:

   1. Move the hot bed assembly back and forth, and shake it up and down to check for shaking or noise.

   2. If shaking or noise, use the M10 wrench to adjust the lower eccentric nut and verify again.

8. Reassemble Rear Bottom Shell:

   1. If there is no abnormal sound, use an H2.0 wrench to fix the M5 rear bottom shell end cover.

9. Reattach Printing Platform:

   1. Use the H2.5 hex wrench to tighten the 5 screws fixed to the printing platform and place the PEI board to complete the Y-axis V-wheel replacement.
