GBR files

Save the g-code and run it through a simulator?

What simulator?

I think I've used freeware called camotics or something like that for some of my cnc work earlier; not sure it will work for a laser - but it should render toolpaths non the less. Haven't spent any time looking for a replacement as Fusion 360 does CAD, CAM and Simulation for me now.

It looks like a registration issue between the raster and vector, probably due to the tracing algorithm.

It's usually very accurate but it's possible that for small traces / pads it could be causing a problem.

What resolution are you using? I did tests at 0.05 (small circuit board someone provided) and engraved on poster board with the contour outline and didn't see an issue.

.05

Just tried to import the gerber again.  All I get is either a circle or a complete blanked out square.  Not sure what is happening.  I reloaded the software and get the same results.  Too cold in my garage tonight to troubleshoot.

Send me the file and I will test it (you can post it here too if you prefer).

Zax,

these are the same files that I have been working with.
Here they are again.

[Zax]

Since they're the old format you need to make sure the units are correct.

Zax,
I'll give it try tomorrow.

Thanks,
Phil

hey zax.  I was trying to invert the colors on a black and white photo and my photo disappeared.  It was a png. I tried another photo and it worked fine.  So I tried a few more.  It seems to be hit and miss which ones will invert the colors and which ones disappear completely.  The files are out in my garage so i'll post them a little later for you to play with.

It is probably related to png format, I look forward to checking them out.

Sorry I posted this in the wrong thread.  I'll post the files in the updates thread
