No-Math Focus Ruler

As long as the material is inbetween these lines does the machine automatically focus or is that a option I am looking over on my page? If you are using a non proofgrade material it asks for you to give an estimate on height…

Thanks for the tool!

Yes and no. It will autofocus either when you use the set focus tool or at the beginning of a print. The advantage of using the set focus tool first is that it will change the camera view based on the height it determined and so placement should be fairly accurate, this basically removes the need to enter a manual material height.

Is the set focus a button in the UI ? New user here… can’t find it! Thanks for the help

It’s behind the gear in settings.

So you don’t need to put in the height of the material even if it’s not proofgrade? Do you just ignore that? Do you have to also go to settings and hit set focus?

Correct, you only need to use the set focus function. That will automatically calculate the material height and change the camera view for that specific height.

Excellent! Thanks! Now with this new no-maths tool I’ve built up the courage to pull out the crumb tray and experiment. Next up, pass through slot!!!

I’m new to this and a little confused.
I thought the material thickness was just that, how thick the wood is.
Not the distance from the laser head to object, which would be the focus…

By inputting the thickness, you are actually telling the machine where to focus. This is why with the honeycomb tray removed, you still must get the material in the range of .001 to .05 from the lens.

The material thickness setting assumes that the material is sitting on the crumb tray, which is approximately 1.4 inches above the bottom of the GF. That setting is only used to adjust the placement of images, not the focus.

As long as the material is between 1.4 and 1.95 inches above the bottom (the lines on the ruler), the GF will be able to focus automatically.

OK, I think I understand it now. I had it in my brain that the thickness setting was to tell the GF on what power level to use according to the thickness. But that is all preset or manually input.

Thank you

The circle hole you cut at the top of the pattern, is that just a holder or does it line up to something?

No, it’s just a hole for a keychain, etc.

Can someone point me in the right direction on how to use one of these files? Do I import it to inkscape? Or do I just put it right into glowforge app?
