Hello all,
New here, I've been working on getting a Chinese fiber laser to work for the past couple days and have had this really weird scaling issue.
When using 110mm field size the laser seems to take short cuts when engraving text, it engraves boxes just fine. I did the scale calibration method of burning a box and measuring with calipers and changing the F3 parameters to adjust. But no matter what the laser seems to be incapable of engraving text. I made a video of the issue and increased the text size to display how increasing the size of the text and leaving the field size the same (110x110mm), allows the engraving to get better and better.

I found that increasing the text size and field size to a huge number , allows the engraver to inscribe near perfect small text and features. The Field size set to 5000mm, and using 200mm height text I could get this perfectly inscribed text, the measures roughly 10mm high with calipers on the work piece. The fiber laser machine is a Raycus 50w laser, and I checked online for the exact focal length, and doubled checked it against the red line pointers on the machine. The focal length to the lens case was exactly 7.49in and it lines up perfectly. Does anyone know what this issue could be ? software settings off? or maybe hardware related? Anything helps, and thanks for your time!
