Just an FYI really, I don’t expect anything to be done about this. The “Clip” feature in inkscape is not supported by GF. Neither is the use of stacked objects and/or layers to prevent the cutting of lower layers. It seems an obscure issue and in a way it is, but clipping lets you effectively cro…

[image] sqw: That doesn’t explain the random walk that is the actual laser cut :slight_smile: Laser cuts produce heat and when you concentrate too much heat in an area, you get material warping, so cuts are spread out to reduce that possibility, when possible.

Here’s the thing also. They haven’t worked extensively on cut path optimization. It saves a minuscule amount of time. My example above shows that. I saved one minute on over 500 inches of cuts. That’s like what, 5%? It takes longer to self-optimize the file than the time savings. I do it because I …

That is true. On a 12"x20" bed, path optimization just does not save much time.

I get optimisation isn’t huge, nor would I put it at the top of the priority list. On the other hand, it is (a) trivial and (b) done on the big cloud server, so for not a lot of coding for even a couple of percent improvement in cut time I’d take that. I’ve said this elsewhere, but cut a living hi…

[image] sqw: it is (a) trivial LMAO over that one. Route optimization is one of the hardest problems in mathematics. Google “traveling salesman problem” and prepare for a rabbit hole. Laser path optimization is just a specific case of that class of problems.

[image] mpipes: Laser cuts produce heat and when you concentrate too much heat in an area, you get material warping, so cuts are spread out to reduce that possibility, when possible. I call BS, the random cuts of the GF are not to reduce heat. I’ll try and put up a video later you’ll see w…

@dan has made a few comments (the most recent was literally today, to you, so I’m not sure why it’s coming up here too?) about how optimizing paths between cuts doesn’t really net you much of a time savings. Today: [image] 13 Things GF needs Everything Else We’ve measure…

You’re just splitting hairs at this point. If speed is an issue people just need to realize they’re up against a wall when they choose 40/45watt hobby machines instead of higher power production units. If you’re seeing really random behavior like partial line segments being cut, then the laser jump…

[image] sqw: I know, because this is the exact area of work I am in right now. That’s great. Can you point me to where to find the solution? Google Nav & Waze have lots of issues that I’d love to find a solution for. I participate in a sport where this is the fundamental problem - how to rout…

As mentioned before, the GF orders the cuts by color.

So you can optimize the ordering of cuts by giving them the right ordering of color.

But then you might have the problem of having to specify in the GFUI a lot of cuts, engraves, and scores.
