Loss of power when sending the same program for engraving again

LightBurn Software Questions
1

Hello.
The problem is the loss of power when sending the same program for engraving again.

I manage the LightBurn program with ComMarker B3

I run the same program over and over again. The first time, I see that the laser has reached the desired power; the target area glows brightly white, and the expected behavior occurs. Then the program ends, I place the next part and press start, and instead of a bright glow, I get a barely visible laser trace. If I try again, the situation repeats itself; the machine doesn’t reach the desired power.

If you restart the program or the machine itself, the first few times it executes the program correctly, but then again it does not reach the specified power.

I use LightBurn 1.6.03
I also tried the latest version of the program.
EzCAD doesn’t have this problem.

During setup, I used the EasyCAD file that came with the machine.

I would also add that if you stop the current engraving using the STOP button and then start it again, this problem does not occur.
