Jigs - what I just found out
... and I wish someone would have told me earlier.
I have been fighting with my jigs for a while. I cut them with the laser, out of wood, assembled them together, they fit well etc. And still every engraving is slightly off and I need to adjust it, sometimes a lot sometimes less. Frustrating.
I went and ordered them made from aluminum.
It is like heaven. Every engraving is EXACTLY the same place.
I spent months fighting this when a simple switch in materials solved the problem.
