Possible to fill flatly without any bevel?

[burnedpickle (Rick Hathaway)]

Hi. I am new to this and have a Longer RAY5 (5W) laser. I am getting an automatic beveling that occurs during fill. Notice the higher center line in the vertical line of the E and side border. Is this an option that can be turned off so that the filled part is flatly engraved, with no shallower center line?
Thanks in advance.

I can see the issue I believe… Wish I had an answer. Maybe someone that uses grbl more than I do can suggest a course of action or debugging to find the issue.

I have 3 machines like yours and a couple other similar types with larger beds.

Since it’s always lined up, I’d check mechanical as a start, but I don’t know what else you might try from a settings point of view…

Good luck

That looks like you are using ‘Offset Fill’, not ‘Fill’. Use normal ‘Fill’ and you won’t get that interior shape.

Thanks Jack for taking time to look at it.

Thanks Oz. I will experiment. So are you saying the ridge is normal for “Offset Fill”, or just that I can work around a faulty “Offset Fill” by doing a normal “Fill”.

Offset Fill isn’t faulty - it just changes speed a lot because it’s following the contours of the shape, and as that happens the laser power varies, so you can get some inconsistency. It was never intended to be a general use replacement for Fill mode - it’s meant for very specific cases, like large open frames with lots of empty space.

Normal fill mode uses very simple movement, scanning side to side, turning the laser off & on as needed while keeping the speed very consistent, and will always give you better quality results than Offset Fill, Flood Fill, etc

Thank you Oz! I am new to all this but love LightBurn. I appreciate that you took time to answer.
