First, it's important to determine whether the issue is happening with ALL needles, or just one or a few.
If it's only happening with one or a few needles, it's possible that the issue could be related to the Upper Dead-End Point. Adjusting this point can often resolve the problem you're facing.
If the issue is happening with most or all of the needles, you can try to adjust the Upper Dead-End Point on the needles having issues to see if this resolves the problem. Otherwise, you will most likely need to replace the Reciprocator.
To adjust the upper dead-end point, please move the head to the affected needle and perform the adjustment below:
- Turn the Main Axis on the back of the machine to 100°.

- Remove the front cover on your machine.

- Disconnect the LED Light Cable.


- Push down the top of the needle bar until the needle catches and stays down when let go.


- Loosen the 2 Allen screws holding the Upper Dead-End point adjustment plate. Once it is loosened, the plate should slide down.


- Turn the Main Axis to 360°. The needle will move up and push the adjustment plate up.

- Once the machine is at 360°, tighten the 2 Allen screws.

- Press the 100° Reset button on the screen to reset the axis. The machine should cycle to 100° and should not have any needles down.
-
Press the Scissor button to test the needle.
If the adjustment was performed correctly, the needle should cycle down and back up.
Once the needle is correctly cycling up and down, you have finished the Upper Dead-End point adjustment and can reassemble the front cover on the machine and test the needles.
If the needle did not cycle down and up, you can try to repeat steps 4-9.
If after making the adjustment, multiple needles are still having issues, you will most likely need to replace the Reciprocator.
Below is a video guide for replacing the Reciprocator:
Once you remove the reciprocator from the machine, you will need to assemble the new reciprocator if you are using the spare included in the toolbox.
