I went to make some bits for halloween and downloaded these silhouettes from Inventables: https://www.inventables.com/projects/halloween-silhouettes?ref=intercom&utm_source=Intercom&utm_medium=Prospective%20Halloween%20Projects&utm_campaign=Cutouts

When I put the svg into Laserweb and generated the gcode and ran it through (TinyG, 5W laser, 6000mm/min) the straight lines were normal speed, but the vectors were incredibly slow - so much that the acrylic felt I was cutting just melted and shrank.

So… I ran the SVGs through AI and simplified the paths, but still ended up with huge gcode files (for the bats, over 1.1M - 60,000+ lines.).

Is there a setting I’m missing? If I make a couple of arcs and use the same settings, it works fine - curves are cut at the same speed as straights.

Or - are they just shitty SVGs?

Use the file segment and type in 0.5 as a value. Most likely the curves are many small paths , this should speed thing up just make sure it does not change the original shape

@Ariel_Yahni_UniKpty thank you. I will give it a go.

@Ariel_Yahni_UniKpty Thats was it. Along with an incorrect setting for my laser beam width.

I went back and simplified the path in AI, tried a number of segment settings from 0.25 - 2mm and ended up with the result I wanted. Thanks Ariel!
