I have been carving lithophanes and the files are huge, between 1.5 and 2 million lines. The problem is that UGS will run the file till about 1/2 to 3/4 of the way through and then freeze up. i dont really see how i would be able to condense the file but is there a different program that i should be running instead of UGS or is there somthing im doing wrong that makes it freeze up?

I've never attempted a cut with that much gcode, but my first thought would be trying to split it into multiple files. Whether you can do it automatically in software will depend on what you're using (you might want to run us through your workflow - I will be of no assistance, as I am a relative newb, but I think it will help our more experienced folks help you find a solution). If you have to, you should be able to manually cut and paste the code into multiple files. As long as you don't alter your work zero between files, everything should line up correctly, I would think. With that many lines of code, it might be a pain in the butt, but less of a pain than failed cuts!

I can't fathom why you have so many lines of code. What is your workflow? It sounds like you're using a tiny mill for the entire project?

That is a large file.
bCNC is more efficient for these really huge files if you want to check it out.
Also, this can depend some on your computers resources I think.

Haven’t done a lithophone yet but do want to do one very soon Jeez the most I’ve had yet is about 500000 and that was complex. You must have a really small bit. What bit and what step over are you using?

It seemed large to me too but that's what it comes out as. I'm using a 1mm ball nose with a .06mm step over. I tried it at .11mm step over but couldn't get enough detail with that size. The picture I am doing is about 100x135 mm so it's not that big. I'm using deskproto to create the file. I stopped using a roughing step first because I'm only going down 1.5mm and the 1mm but can handle that all in one pass. I wouldn't think that would make any difference though

I wonder if you're cutting to shallow and thus barely cutting with the tip of the ball opposed to the whole radius?

Sorry I was editing when you wrote that. I'm only going down 1.5mm in a single pass

Sorry I was editing when you wrote that. I'm only going down 1.5mm in a single pass I was editing too so you answered my question. Lol. You might try roughing it with a 1/8" ball at a 40% step over leaving about .005" of material. Then go back with your 1mm ball at 10% and see how that works.

Also, is it cutting both directions?

I tried roughing with an 1/8 flat endmill at .32 step over and then finishing with .11 step with the 1mm ball nose but it lacked a lot of detail. Do you think the roughing with the endmill would have anything to do with that. What do you mean is it coming both ways?

Cutting moving right and cutting moving left. Maybe it's because it's late and my brain isn't working right, but what do you mean lacks details? It's just not picking up details or it's leaving a rough surface?

Ya know I thought about that but it doesn't seem like it's cutting when it's going back to the left. Which I assume means that it's only stepping when it's going to the right which would pretty much double the code unnecessarily. Wei8th the .1 step over it leaves like lines and when you hold it up to the light it looks like your looking at a blurry picture

Maybe I missed it somewhere in the thread above, but what software are you using to create the code? That seems like a huge file. I've done a few Lithophanes and they are no where near that long of a file.. Using a 1/16" tapered ball nose with a 6% step over, about 250k lines of code and a 5X7 size output.
