Add lines to fill?

[aberegal (Stefan)]

Hello,

I have searched a little bit now, but I cannot find an answer to the following question:

Is it possible to add the dimensions of the lines to a fill?

What I mean by that: If I had a 3px thick line, where 1px is filled and a 1 px line is burned on the left and right side of the fill, then I would like to include this line in the filling.

So I would like to get a 3px line only by filling without having to line afterwards. Is that possible somehow? If I burn very thin lines, then these become too deep when I line after filling.

I’ve tried it with the offset shape-function, but this did not worked as expected …

Best regards
Stefan

Do you have Z control on your Ortur Machine? If not, you could still perhaps manually out focus Z for the thicker vector engraving.

‘Fill’ happens within (and including) the lines you define the shape with. Lasers don’t use “pixels” because I have no idea how big your beam spot is. Just fill, but use a small enough interval value (or high enough DPI) to get good vertical resolution.

Hi,

thank you for your replies.

Okay, I probably expressed myself badly

I have traced a B/W PNG to be able to “flood fill” it instead of burning the image:

The Preview of the fill looks like the desired result.

I start to fill with the following settings (15w version of the laser master 2)

but the result does not look like the preview. The lines are way to thin especially the line left of the C27:

Only when I line it up afterwards it looks something like in the preview. But this makes thin lines too deep and it takes longer because of the extra step:

I don’t have a Z control so I’m hoping for some kind of setting to get the flood filled lines as thick as they look in the preview. I’ve tried it with more power, slower with more power, with more lines per inch (200, 254 and 300).

Edit: Oh and it doesn’t matter if the image is burned 55 mm or 160 mm wide. I’ve just made it smaller now to save time but the lines are to thin, even if the burned image is much bigger.

You might not have your focus set properly - diodes are quite sensitive to this. The lines you’re showing don’t look thin, exactly, they look like they’re not fully engraving. Flood fill is not advised on complicated images like this, because it will jump all over the place. You’ll get more consistent results if you just turn on ‘Fast Whitespace’ in Edit > Device Settings, and set the skip speed relatively high. If you do that, you can set the burn speed a little lower, which will also help.

You might need more overscan too - if the laser is not moving at the requested speed when it starts burning, it will reduce the power output to compensate for it, and some material has a threshold below which it won’t burn.
