5-7 Material cannot be cut through

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.

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.
  Mirrors and Lens Cleaning
  

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, making them unacceptable.

• Please refer to the article below to check your focus distance and readjust it if necessary.

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.

Step 1.4 - Check the power curve settings

The laser output may be affected by the setting of the power curve.

•  Please refer to the link below to set the power curve to 25/100.
  (The low/left value does not have to be changed.)

Step 1.5 - Run the same task

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

Determine your result and the next action to take:

Step 2 - 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
   

Step 2.1 - 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 perform auto-focus.

• Cut the example file in Beam Studio.
  

Determine your result and the next action to take:

Step 2.2 - Re-update the firmware

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 focus.
  

• Cut the example file in Beam Studio.
  

Determine your result and the next action to take:

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:

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] 

*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.
