¶ Compatibility
This article applies to the following model and module. Please take note when referencing:
Model: U1
¶ Issue Description
After assembling the U1, you may encounter an anomaly during the first calibration or initial print job where the toolhead cannot be picked up or parked correctly.
¶ Possible Causes
-
Excessive force applied while installing the filament holder may cause the left inner panel or right inner panel to pop, obstructing the toolhead from returning home.
-
The latch was not positioned correctly when placing the toolhead onto the toolhead rack. The red indicator should be visible before installation and hidden after the toolhead is secured.
-
The timing belt is not properly tensioned.
-
The pick-and-park coordinates of the machine are incorrect.
¶ Troubleshooting Steps
¶ 1. Check the left inner panel and right inner panel
Check whether the left inner panel or right inner panel has popped out. If so, reinstall them securely and test again.
¶ 2. Confirm the latch red indicator status
When all four toolheads are placed on the toolhead rack, the red indicator on each latch should not be visible. Refer to the sample image for confirmation.
¶ 3. Re-tension the timing belt
If you already adjusted the timing belt once during assembly, please follow the guide to adjust it three additional times.
Manual tensioning can vary slightly, and repeating the adjustment helps ensure proper belt tension. Follow the instructions below and check whether the issue is resolved.
¶ 4. Adjust the pick and park coordinates
If the above items are all normal, the issue may be caused by incorrect pick-and-park coordinates for the affected toolhead. Follow the steps in the wiki article below to correct the coordinates. The procedure may be detailed, and we appreciate your patience.
¶ 5. Record a video and contact support
If adjusting the coordinates does not resolve the issue, record a video that clearly shows the anomaly and contact Snapmaker Support for further assistance.
