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.
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: 5-2-7 Material cannot be cut through (beamo)
----------------------------------------------
Step 1 - Clean all the mirrors and the focus lens
Dirty mirrors and a focus lens will cause the laser output to be weaker.
- Please follow the instructions in the link below to clean all the mirrors and lenses.
4-3-4 Mirrors and Lens Cleaning - After cleaning, go to Step 1.1 - Make sure the parameters are correctly set
----------------------------------------------
Step 1.1 - Make sure the parameters are correctly set
Sometimes, people forget to change the parameters on the panel or in Beam Studio.
- Beam Studio:
- Panel:
- After checking or adjusting, go to Step 1.2 - Check the focus distance.
----------------------------------------------
Step 1.2 - Check the focus distance
An incorrect focus distance will affect the cutting or engraving results to be unacceptable.
- Please refer to the article below to make sure you focus in the correct way.
[5-2-16 Adjusting the focus] - After checking or adjusting, go to Step 1.3 - Check the optical path.
----------------------------------------------
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.
- Please carefully follow the instructions in the link below and realign the optical path if necessary.
[4-3-5 Optical Path Inspection] - Please keep the collection of tapes after finishing the inspection.
- After checking or realigning, go to Step 1.4 - Run the same task
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
- No, it still cannot be cut >> Go to Step 1.5 - Testing material preparation
----------------------------------------------
Step 1.5 - Testing material preparation
In order to do further testing, please prepare either one of these two materials as listed below.
- 3mm transparent acrylic (Recommended)
or
3mm MDF wood - After the preparation, go to Step 2 - Center Cutting Test
----------------------------------------------
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.
Please make sure to focus before starting the task. - Cut the example file in Beam Studio.
Determine your result and the next action to take:
- Yes, it can be cut in the center >> Go to Step 3 - Bottom-right cutting test
- No, it cannot be cut in the center >> Go to Step 2.1 - Reset to Factory
----------------------------------------------
Step 2.1 - Reset to Factory
Sometimes, a firmware failure may cause the output of the laser to be abnormal.
In order to exclude the possibility of 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:
- Yes, it can now be cut in the center >> Go to Step 3 - Bottom-right cutting test
- No, it still cannot be cut in the center >> Go to Step 4 - Increase the power rate and lower the speed
----------------------------------------------
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.
Please make sure to focus before starting the task. - Cut the example file in Beam Studio.
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) - No, it cannot be cut in the bottom-right area >> Go to Step 3.1 - Re-check the Optical Path
----------------------------------------------
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
- No, it cannot be cut in the bottom-right area >> Go to Step 4 - Increase the power rate and lower the speed
----------------------------------------------
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:
- 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:
- Yes, it can now be cut in the bottom-right area or the center >>
Hardware issue: Laser tube decline or Laser PSU having problem >> Go to Step 5 - Report to the local reseller or FLUX Support - No, it still cannot be cut in the bottom-right area or the center >>
Complex issue: Laser System (Laser tube/PSU) or Control System (Boards or Sensors) >>
Take a picture of the failed result >> Go to Step 5 - Report to the local reseller or FLUX Support
----------------------------------------------
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 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.
