Hi guys, It seems i have been able to find the answer to all my other problems through Bitcoin and its community so here goes another attempt.

I am looking to have a laser engraver engineered that does not suffer from the "straight line" problem.

The straight line problem can be better understood by watching this video

Buying and off the shelf laser engraver means i could only engrave things that are round which have a perfectly straight line to write on, So something like a vase which has curves cannot be engraved as the laser is out of focus on any part of the vase that is not on the focus line.

I would be willing to offer a negotiable fee or bounty to anyone who could solve this engineering problem. You would not need to build the actual machine. Just provide engineering documents and a parts list so i could build it DIY style.

Thanks

Did anyone ever provide this for you?

+1, sounds easy to fix. What's the focal distance tolerance?

Distance could be changed with adjustable optics, but angle on highly sloped surfaces would still be an issue. You might need to tilt the laser head in addition to adjusting the distance. Depending on your setup, controlling the z distance with a slide rail might be easier than adjustable optics. It'd be a fun project, but I'm sure there must be something out there that does this already.
