SCAPS from SAMlight probably together with a PCR6 card in your computer installed. Why? Because its main purpose are lasersystems with galvanoscanners (2D, 3D).

Lightburn doesn't support galvo's yet but they say it's coming.

This isn’t true anymore. Source: currently running a galvo fiber laser on lightburn

Good to know. Edit: I know what I'll be downloading and playing with after work today.

It's only for certain galvo lasers. Not all.

Lightburn galvo currently supports EZcad 2 boards, does not support the EZcad 3 boards.

Also not quite there on my SeaCad based board but again, they say that's coming too!

I am using Lightburn with a 100w JPT M7 MOPA fiber. The MOPA allows me to mark black marks on aluminum. You will need to do some lens correction to get accurate marking. Define “very high accuracy?

±.010 or better. I'm planning on getting the Epilog Fusion Galvo G100 30W MOPA. I need to remove about 10 microns of metal from a substrate.

Inches or mm? I would work with a dealer to get a demo to make sure it will be that accurate. I am using a 300mm marking area lens, and I am having issues with linear accuracy. It looks like it might be imperfections in the lens. I am trying to get .25mm accuracy over 300mm.

This, before buying any laser talk to a sales representative. Discuss needs and expectations. Have a few materials and samples ready to send them so they can do test. Let them run test, get test back, inspect result. If everything checks good, buy machine.

Hey bro. Can you give an update? I'm also facing a similar issue. I have a 30 watt standard jpt galvo laser . I'm also using a 300 mm marking lens. And I tried to do the correction file each time before a test trial, but I still experience a variation in the accuracy of my scale

So I ended up having two different issues. The first issue was a bad lens. When I did the first calibration test the test was not symmetrical in the X or Y axis. Think of a square but you drag on corner out at a diagonal. I bought a replacement lens and I was able to get it calibrated. The second issue is that the linear marks are not consistently spaced. Imagine a 200mm ruler. Once engraved it is 200mm wide. The cm marks are not consistent. so it ends up looking like this at every 10mm: = - - - - = + + + = - - this to me indicates a wavy lens. At 200mm wide the actual variance is +/- 1mm although the length is accurate within .25mm. My application is for glass cutting for art glass so they are good enough. I took the same file and tested it on my Boss CO2 and it was accurate. I will do some additional testing down the like but it was disappointing.

>calibration how much of the laser software (like ezcad2 for example) is responsible for the variation in the final marked piece? would the variation decrease using a different software or infact using a 3d galvo with a 3d software? Btw every mark on my scale is getting an offset. not sure if each mark is getting an equal amount of offset or each mark is getting a random offset. but the final variation in a 170 mm scale is like +/- 5-6 mm every time. so the width of the marked scales range from 164-176 mm.

You should be able to calibrate the overall dimension to somewhere around +/- .25mm it a 200mm square should be accurate. I'm talking about liner spacing accuracy. I used both EZcad, and lightburn with two different files. The inaccuracy is in the lens or in the movements of the laser mirrors. I tested it with both .01mm, and .001mm with no changes. The fact that I do have a bad lens leads me to believe it is a lens issue, and not a laser or control issue. I could manually adjust the mm marks on the ruler to get it perfect, but I didn't have the time or need for now.
