I have a 50W Chinese CO2 with a 2 inch focal length lens.
I tried different scan angles and setting it to a 90 degree (vertical) scan dropped the estimate to about 51 minutes (so it dropped around 6 minutes).
It’s at 250mm/s, 35% power, 0.100 Line Interval, 254.00 Lines per Inch. Other than the 250mm/s & 35% power, these settings are the defaults that Lightburn had when I connected it to my laser. I used 250mm/s because when I tried engraving aluminum business cards, I saw some blurring of the text at 300mm/s (although that was before I changed heads and the mount for the head).
The material is the 99.5 % coir, 0.5 % polyethylene door mat from IKEA.
I don’t believe I’m using an image mode. Everything in the Fill layer is an SVG or text from Lightburn. There are no bmps or other images.
I’m not trying to hit a specific target, I’m just trying to see if there is a way to make the engrave fill take less time. The fact that it’s skipping around so much makes me think that there has to be a better way to optimize the burn. If I can’t lower the amount of time it takes, it makes me second guess if I should be making these for sale.
