------------------------------------------------------------------------------------------------
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.
Determine your result and the next action to take:
- It CANNOT be moved like the video above. >> Go to Step 1.1 - Lubricate the rails
- It CAN be moved like the video above >> Go to Step 2 - Exclude the possibility of firmware issues
------------------------------------------------------------------------------------------------
Step 1.1 - Lubricate the rails:
- Please refer to the instructions in the link below to lubricate the rails.
[4-3 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
- No, it still cannot be moved like the video in Step 1 >> Hardware issues: rails may be rusted
>> Take photos or videos and Go to Step 9 -Report to the local reseller or FLUX Support
- Examples of the photos or videos for reporting:
- X-axis rail:
- Y-axis rail - Left:
- Y-axis rail - Right
- X-axis rail:
- Examples of the photos or videos for reporting:
------------------------------------------------------------------------------------------------
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
- No, the homing is not done properly after the reset
>> Go to Step 3 - Check the behavior of your machine when homing
------------------------------------------------------------------------------------------------
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".
>> Go to Step 4 - Reflash SD card. - 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.)
>> Go to Step 4 - Reflash SD card. - Behavior #3:
The head reaches the top or the top-left corner but it doesn't stop and makes a grinding sound.
>> Go to Step 6 - Check Limit Switches. - 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.)
>> Go to Step 5 - Switch DriverIC. -
Behavior #5:
The head stops at Y-axis.
(*A Beambox Pro is used to demonstrate the behavior in the video.)
>> Go to Step 6 - Check Limit Switches. - 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.
>> Go to Step 6 - Check Limit Switches. - Other behavior:
- If none of the examples above is similar to your homing issue, record a video showing your whole homing process from the beginning til it fails. (Video example)
- After recording the video, go to Step 9 -Report to the local reseller or FLUX Support
------------------------------------------------------------------------------------------------
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.
- Please refer to the instructions in the link below to reflash your SD card.
[5-24 HEXA - Reflashixng SD Card]
Determine your result and the next action to take:
- Yes, the homing is now done properly after the reflash >> Problem solved.
- No, the homing is not done properly after the reflash
>> Go to Step 5 - Switch DriverIC.
------------------------------------------------------------------------------------------------
Step 5 - Switch 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.
- Remove the side cover of the machine. Please refer to the article where how to remove the cover is mentioned.
- Unplug the DriverIC of the Z-axis. Please refer to the diagram.
- Unplug the DriverIC of the Y-axis or X-axis depending on which axis has failed during homing.
(Unplug Y's if it failed to go top. Unplug X's if it failed to go left after reaching the top.)
Please refer to the diagram. - Switch both DriverICs and make sure the direction is the same as in the diagram. (Plug Z's into the other axis's and the other into Z's)
- Turn on the machine and try homing again.
- Try using the autofocus function.
Demonstration:
(This video shows switching the ICs of the Z-axis and Y-axis.)
Determine your result and the next action to take:
- The homing and autofocus now work properly >> Problem solved.
- The homing works but autofocus does not. >> Hardware issue: DriverIC
>> Record a video showing your problem (Video example) and go to Step 9 -Report to the local reseller or FLUX Support: - The homing still does not work >> Hardware issue: Motor, Mainboard, or DriverIC
>> Record a video showing your problem (Video example) and go to Step 9 -Report to the local reseller or FLUX Support:
------------------------------------------------------------------------------------------------
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.
- 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)
Determine your result and the next action to take:
- Both X-axis and Y-axis work properly as in the video >> Go to Step 7 - Check the levelness of the X-axis
- One or both don't work >> Hardware issue: Mainboard or Limit Switch
>> Record a video showing your problem (Video example) and go to Step 9 -Report to the local reseller or FLUX Support.
------------------------------------------------------------------------------------------------
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
- It is parallel but Y-axis fails in homing >> Go to Step 8 - Adding Foam to trigger Y-axis Limit Switch
- It is parallel but X-axis fails in homing >> Unknown issue
>> Record a video showing your problem (Video example) and go to Step 9 -Report to the local reseller or FLUX Support
------------------------------------------------------------------------------------------------
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 photo below.
Determine your result and the next action to take:
- The machine can now home after adding the foam >> Problem solved
- Homing still fails >> Unknown issue
>> Record a video showing your problem (Video example) and go to Step 9 -Report to the local reseller or FLUX Support:
------------------------------------------------------------------------------------------------
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.
