Description:
Due to the complexity of the cause behind #904, it's important to note that reading this article may not provide an immediate solution to your problem. Nevertheless, by carefully following the steps below, you will gather valuable information that can help your resellers or FLUX Support in pinpointing the issue more effectively. This, in turn, will contribute to reducing the overall time required for troubleshooting.
Possible causes:
- The system fails (Re-update the firmware, reset to factory, or reflash SD card.)
- The mainboard/MB/motherboard is malfunctioning.
- The limit switch is malfunctioning.
- The guide rails rusted or are damaged.
- The X-axis levelness is not horizontal.
- DriverIC is malfunctioning.
- The step motor is malfunctioning.

Step 0 - Use the checklist while going through the steps:
This checklist will be used to record all your taken actions in this article.
After completing the checklist, please print it to save as PDF and send it to your reseller or FLUX Support if necessary. This will be useful information for us to troubleshoot and narrow down the issue.
Please refer to the link: 5-2-5 #904 Homing Failed Checklist (beamo Series)
Step 1 - Check if the laser head is physically stuck:
- Turn off the machine and unplug the power cord.
- Manually move the laser head toward all four corners.
(*A HEXA is used to demonstrate the behavior in the video.)
Determine your result and the next action to take:
Step 1.1 - Lubricate the rails:
- Please refer to the instructions in the link below to lubricate the rails.
[4-3-1 Lubricating]
- After lubricating, try moving the laser head again and see if it can move like in Step 1.
Determine your result and the next action to take:
- Yes, it can be moved like the video in Step 1. >> Problem solved

Step 2 - Exclude the possibility of firmware issues:
Sometimes, the homing issue may be led by firmware being incorrectly installed.
Resetting the system is a simple and quick way to fix the homing problem.
-
First of all, try to Reset Mainboard Settings.
(Machine > Hardware Settings > Reset Mainboard Settings)
-
Next, try to Reset to Factory. (Machine > Reset to Factory)
-
Finally, update to the latest firmware and try homing again.
(Machine > Update to the latest Firmware) or you can use Beam Studio to update. (Link)
Determine your result and the next action to take:
- Yes, the homing is now done properly after the reset >> Problem solved
|
Step 3 - Check the behavior of your machine when homing:
Please turn on the machine and press "Maintain" to start homing and determine which behavior is similar to your machine's and take action accordingly.
-
Behavior #1:
The laser head is not moving and is not being locked.
However, it can be moved manually while the panel shows "Homing".
(*A HEXA is used to demonstrate the behavior in the video.)
|
-
Behavior #2:
The moving direction is opposite or the head is moving back and forth.
(The correct movement is to go top first and go left after. It will never go down or right when homing.)
(*A HEXA is used to demonstrate the behavior in the video.)
|
-
Behavior #3:
The head reaches the top or the top-left corner but it doesn't stop and makes a grinding sound.
(*A HEXA is used to demonstrate the behavior in the video.)
|
-
Behavior #4:
The head is making a grinding sound even if it does not reach the top or the top-left corner.
(*A Beambox Pro is used to demonstrate the behavior in the video.)
|
-
Behavior #6:
The head shakes a few times then the error pops up or it reaches the top and it shakes then the error pops up.
(*A HEXA is used to demonstrate the behavior in the video.)
|
-
Behavior #7:
The Head bounces back when moving up toward the Y-axis.
(*A beamo is used to demonstrate the behavior in the video.)
- This is more likely to be caused by the plastic chain hitting the frame of the machine.
Manually adjusting the chain by pulling it up or pushing it down is suggested to solve the issue.
|
|
Step 4 - Reflash SD card:
Sometimes, if the operating system in the SD card is corrupted, the homing issue won't be fixed by resetting and updating the firmware. It will have to be fully rewritten by reflashing the SD card.
Determine your result and the next action to take:
- Yes, the homing is now done properly after the reflash >> Problem solved.
|
Step 5 - Swap DriverIC:
DriverIC is a component on the mainboard/motherboard and it is used to drive the motor in order to make the laser head move in different directions. In this Step, we will have to test if the homing issue is led by the DriverIC.
- Turn off the machine.
- Open the front case to find the mainboard. Please refer to the article where how to open the case is mentioned.
- Unplug the DriverIC of the X-axis. Please refer to the diagram.
(Make sure you remember which IC is for which axis originally)
- Unplug the DriverIC of the Y-axis. Please refer to the diagram.
- Swap both DriverICs and make sure the direction is the same as in the diagram.
- Turn on the machine and try homing again.
Demonstration:
(This video shows swapping the ICs of the X-axis and Y-axis.)
Determine your result and the next action to take:
-
The homing now works properly >> Problem solved
- Possible cause: improper connection
|
Step 6 - Check Limit Switches:
A limit switch is used to stop the laser head when it reaches the end.
Homing issues may be led by the limit switch being faulty which will result in the laser head not stopping or stopping too early.
- The limit switches' locations for beamo:
- Please see the video below to check if your limit switch icons are reacting correctly when being pressed. (Pressed = icon closes / Not pressed = icon opens)
(*A HEXA is used to demonstrate in the video.)
Determine your result and the next action to take:
Step 7 - Check the levelness of the X-axis:
- Refer to the link below for how to test and adjust the levelness of the X-axis.
Make sure that the pulley/wheel is not loose referring to the ending of the video.
[5-29 X-axis Levelness Adjustment]
Determine your result and the next action to take:
- The machine can now home after the adjusting >> Problem solved
(Possible cause: X-axis was misplaced.)
|
Step 8 - Adding Foam to trigger Y-axis Limit Switch:
- The limit switch's triggering metal as circled in red might get loose over time and it will affect the sensitivity of the limit switch to be triggered. This usually happens with a Y-axis limit switch.
- Here is a quick fix. Please add a piece of foam to the X-axis motor as shown in the photos below.
- Make sure that the foam is lower than the frame. Otherwise, it might block the path to reach the limit switch.
Determine your result and the next action to take:
- The machine can now home after adding the foam >> Problem solved
|
Step 9 -Report to the local reseller or FLUX Support:
- Please follow the instructions in the link below to properly report an issue to your local reseller or FLUX support. [Contact Customer Service]
- Make sure you've completed the checklist and saved it as a PDF file so you can share your taken actions.
*The collected information such as photos or videos that show the problem of your machine in this article will be necessary to be shared with the reseller or FLUX Support.
