5-5 Material cannot be cut through

FLUX Support Team
  • Updated
Descriptions

When materials cannot be cut through, there are many possibilities that may cause the issue such as focus distance being incorrect, the optical path being misaligned, laser tube decline...etc.
However, based on our experience, it is USUALLY caused by the optical path being misaligned.

Please follow the steps below to determine what causes the issue.

 

Possible Causes

  1. The optical path(OPA) is misaligned.

  2. Wrong focus distance

  3. The mirrors are dirty or damaged.

  4. The focus lens is dirty or damaged.

  5. The system fails (Re-update the firmware, reset to factory, or reflash SD card.)

  6. The power rate and speed are set wrong in the software.

  7. The laser tube has declined.

  8. The material is hard to cut.

  9. The laser power supply (Laser PSU) is malfunctioning.

  10. The honeycomb platform level is not horizontal. (Less likely)

 

Preparation Items

The necessary tools will be mentioned in each step as some steps might be skipped. 

 

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: 6-3 Cut Didn't Go Through Material (Beambox)

 

Step 1 - Clean all the mirrors and the focus lens

Dirty mirrors and a focus lens will cause the laser output to be weaker. 

 

Step 1.1 - Make sure the parameters are correctly set

Sometimes, people forget to change the parameters on the panel or in Beam Studio.

 

Step 1.2 - Check the focus distance

An incorrect focus distance will affect the cutting or engraving results to be unacceptable.

 

Step 1.3 - Check the optical path

Based on our experience, when materials cannot be cut through, it is USUALLY caused by the optical path being misaligned.


Before going to the next step, please do know that:
All steps after Step 1.3 will be based on the optical path is well aligned.
If you still cannot confirm whether your optical path is good or not after reading the article mentioned above, please stop going through this article and directly contact your local reseller or FLUX Support for help.
(The collection of tapes will be key information to target the issue of OPA.)

 

Step 1.4 - Run the same task

  • Run the same task with the same material and see if it can now be cut.

Determine your result and the next action to take:

  • Yes, it can now be cut >> Problem Solved

 

Step 1.5 - Testing material preparation

In order to do further testing, please prepare either one of these two materials as listed below.

Step 2 - Center Cutting Test

We are going to test the cutting ability in the center of the bed.

  • Place the prepared material (3mm acrylic or wood) in the center of the bed and make sure to focus.

  • Cut the example file in Beam Studio.
    Step


Determine your result and the next action to take:

 

Step 2.1  - Reset to Factory

Sometimes, a firmware failure may cause the output of the laser to be abnormal.
In order to avoid firmware issues, please reset the machine.

  • Reset to Factory. (Machine > Reset to Factory)

  • After the reset, please cut the example file again, as in Step 2.

 

Determine your result and the next action to take:

 

Step 3 - Bottom-right cutting test

In this step, we are going to test the cutting ability in the bottom-right area of the bed.

  • Place the prepared material (3mm acrylic or wood) in the bottom right area of the bed and make sure to focus.358165.jpg

  • Cut the example file in Beam Studio.
    Step


Determine your result and the next action to take:

  • Yes, it can be cut in the bottom-right area >> The machine is considered no issue >>
    The problem might be material-related. Please customize your own parameters.
    (Increase power rate, lower speed, or execute more times)

 

Step 3.1 - Re-check the Optical Path

Based on the condition of the machine, if the material can be cut in the center, but not in the bottom-right area, it is likely the optical path can be re-adjusted and improved.

Please go back to Step 1.3 - Check the optical path. and make sure that your OPA is well aligned.

If you still cannot confirm whether your optical path is good or not after reading the article mentioned above, please stop going through this article and directly contact your local reseller or FLUX Support for help.
(The collection of tapes will be key information to target the issue of OPA.)

 

Determine your result and the next action to take:

  • Yes, it can now be cut in the bottom-right area >> Problem solved

 

Step 4 - Increase the power rate and lower the speed

In order to narrow down the issue, we are going to check if raising the power rate and lowering the speed can improve the cutting result.

  • Beam Studio:
    Step


  • Raise the default power rate by 20%.
    (If the default is 15%, then 15% + 20% = 35% will be set)

  • Lower the default speed by half.
    (If the default is 300mm/s, then 300mm/s *0.5 = 150mm/s will be set)

  • Run the same task and see how it goes.
    • If it failed in the center last time, re-test the center.
    • If it failed at the bottom-right area last time, re-test the bottom-right area.

 

Determine your result and the next action to take:

 

Step 5 - 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 actions. 

*The collected information, such as photos or videos that show the problem with your machine in this article, will need to be shared with the reseller or FLUX Support.
