Focus issue with Acmer P1

[rusko]

Hi guys,

I made a "focus test" with my new Acmer P1 10w and the result is... well... go on reading.

Left side is on the base, right side is 15mm higher. I made 4 lines:
1) 300mm/min, 1 pass, 70%
2) 300mm/min, 2 pass, 70%
3) 500mm/min, 1 pass, 70%
4) 500mm/min, 2 pass, 70%

The marker "Focus" (in the middle) is where the laser is at the "nominal" distance (set with a "spacer" mounted on the laser itself), the marker similar to a Φ (on the right) is where the laser touches the board (3mm thick).

This is the Front side.

Here is clearly visible how thick the line is on the right and how thin is on the right.

This is the back side.

down.jpg (50.43 KiB) Viewed 307 times

Here again, the board is cut near where the laser touches it.

I was expecting to see the "best cut" near the "focus" marker...what's is going on?
Any suggestions/ideas?

Thank you very much for your attention and for any advice you can give me!

Regarding the focus issue with Acmer P1, ensuring proper focus is essential for achieving optimal laser engraving results. Start by checking the focus lens and making sure it's clean and free from any debris. Additionally, ensure that the material surface is flat and positioned at the correct focal distance from the laser head. Experimenting with different focus settings and running test engravings can also help pinpoint the ideal focus for your specific application. If the issue persists, considering reaching out to Acmer P1's customer support for further assistance.
