a good trace and an LPI of 340 or higher will help reduce this aliasing as well:

I’m really glad that there are much more knowledgeable people than me working on this stuff…
I get most of what you’re saying, but there are parts in there that make me feel like Penny when she talks physics with Sheldon

If you need further explanation, let me know. Ill be glad to go into detail. I think I wrote up a whole tutorial on tracing images for the GF already. lemme see if I can find it.

Awesome, yes, would love to read that, thank you! One of the main things I wasn’t to make is engravings…

Oh, and this is where I got the pic from, if it helps anyone in any way:

Here ya go. This should explain the trace function, as well as some other potentially useful things:

That “connect the dots” looking trace will be engraved just fine by the forge?
well I went to test it to make sure, but I got this error:

whoa, they taking away your pre release?!

No I think I made the file to be uploadable to the forums, but that makes it not work in the GFUI. Let me upload a zip for you. (thats the first thing you start to think though! haha)
flag.svg.zip (34.3 KB)
Hehehe, scary, right?
AND HOLY COW, THAT’S SO CLEAN!! Thank you!!
So that is just from using Illustrator’s Trace function??

I see it somewhat differently. I don’t see it as banding above/below EMPIRE, I see it as overly darkening on the left and right sides of EMPIRE. You also see it happening right across the window of the Tie-Fighter, where you’re getting some denser dark/white spots. The above/below being lighter looks to me that it’s ‘recovering’ more.
I think the laser or PSU is having a hard time switching states. It’s either staying energized for too long, or the amount of energy is collapsing too quickly, like a curved amount of energy output rather than linear.
yeah super easy and quick. Thats why its my favorite thing in Illustrator =)

I’m blown away, changing my world…
Thank you SO much

There is a thin border that goes all the way around the outside of the image. In the raster version you can see the power loss propagate even out to that outer border, so it really is a loss of power. Im almost 100% sure it has to do with the design of the cooling in the tube in my unit. It has way fewer coils than the newer models.
My k40 experienced similar issues when too much water from the cooling pot evaporated causing the heat dissipation to drop. It would start banding in areas that required more output.
I have a few more examples I can probably show. Ill have to dig them up. I bet if I amped up the cooling in this pre-release version I could get it to engrave without those issues.

Here you can see a consistent depth across the piece, except right before and after where the letters sit.
You can see the ramp up at the beginning from proper height to that peak that is created right before going back down to the correct depth when it hits the lettered areas.

Yeah, you’re probably right it’s more related to cooling than drive power. Thinking about it harder, if it were drive power then your edges of dark/white transitions would be more inconsistent (and probably more zigzaggy, since the head flies in both directions)… With better cooling, it would affect the heat transfer more, letting it be more consistent.
Have you tried letting one of the newer PRU’s burn your files?

Yeah, they run perfectly now. Maybe even a bit too much power. Really good to see. Cant wait to get my hands on a working on. So many things Im waiting to make… I literally have shelves of materials waiting

Not a problem man. Ive been a photoshop user for most of my life. I never really had too much of a reason to use illustrator very often until now. Im really loving it when working with the laser (one that can accept vector images at least =) )
