Power peaks on the begin and end of the pass
Hi there,
I have a problem with my Universal ULS25E laser engraver. It seems that the laser power fluctuates and it's higher on the beginning of the pass, then it drops and peaks again by the end of the pass.
Please have a look at the attached screenshot. It's an raster engrave. The material is transparent acrylic sheet painted white and black.
Anyone experienced something similar? What might be the cause?
The machine has replaced X-Axis motor to a different one. It has the same rotations per step but it draw more amps and it's bigger. However I doubt it's related. I believe if there would be a problem with the motor I would be getting distorted image not peaks in laser power.
Best,
Bartek
