Thank you for the additional context. I can see how printing on a wide range of materials and objects could make setting up prints challenging!
As far as general tips go, here are two posts in particular where other Glowforge owners have shared methods they used beyond the tools in our app to align prints:
- Glowforge Interface - How to Align a Double Sided Engrave
- Placement of Designs in WebApp is off because of Distortion of Bed Image due to Fish Eye Lens
We’ll ensure that your suggestion is shared with our product team. If you run into trouble with your Glowforge, or have other questions, please reach out and we’ll be happy to help!
