Just ran a 16" diameter Acacia wood piece on my Xtool D1 10 watt (non pro) in Lightburn. Had to do a ton of editing on a saw blade perimeter graphic to get it all closed up but it was a good learning experience. Initial check showed it was gonna take 11-12 hours to burn. Found out about the whole flood fill and fast white space. Selected flood fill on these layers and set fast white space to 7000mm. Cut my time down to less than 2.5 hours so I proceeded. There are some odd areas around the perimeter of many areas shown in the photos. They are deeper than the surrounding engraved areas. The two settings above changed how it engraved (didnt do the printer back and forth across the whole puece) What might cause this? Its never happened on any other engraving ive done not using these commands. Im hoping i just missed a couple other settings i should have tweaked.
Exactly what you changed.
Because the laser is scanning only within the letters, it must speed up and slow down within the letters, rather than running at a constant speed across the entire design.
Although the controller tries to adjust the power to compensate for the varying speed, the complex interaction between speed / power / material results in varying burn depth.
If you want a constant result (color / depth / texture / whatever), you must set the machine to scan across the entire design at a constant speed.
You may be able to do that by filling each letter separately with overscan on each side; check the Preview simulation to verify the overscan area is behaving the way you need.
Thank you gor the info. Ill check the overscan and see if things change.
