When I look at my screen to design the text and font onto an object in the glow-forge, all looks great until I hit print! The text on the bottom is immediately off and this throws off the entire project, ugh!
As @beerfaced says, set focus is your friend. It really makes a difference.
From your photo - it looks like your candle lid is sitting on top of another 1/8" sheet of something? My candle lids are on the fat side, make sure that your total height isn’t more than 1/2", the GF can’t focus higher than that.
That’s definitely chunkier than 1/2". You’ll have to take the crumb tray out and prop the lid up to the proper height to get a properly accurate focus. I @dwardio’s no math focus tool for jobs like this
To keep from wasting supplies, you can add some masking tape and a power of 1 to see ‘where’ it’s going to laser. Remember the camera is fisheye so what ‘looks’ right on the screen isn’t necessarily the right place to print it!!
