While trying to cut some fabric with the Ortur Laser Master 2, we ran into a strange curiosity in light burn. We found that different SVG types generated different GCode for the same shape. After this we managed to put together a table of cutting settings for various fabric colors.
SVG Types
The rectangle SVG type ends up with different GCode that is much less powerful when cutting (fabric in this case). While the path SVG type ended up with strong cutting power through the fabric.
The path type with the exact same settings and same square shape cut perfectly where the rectangle type would just engrave the black fabric (and do absolutely nothing to white fabric)
Cutting Settings
This is all with the G8 lense on the Ortur Laser Master 2 20w model. Below is a table of the cutting settings we used on various fabric types, this is all with the path type for SVGs.
