Question about sliding table in Galvo

Thank you.

The plan is to be used in any kind of repetitive job including pen, cutlery, tags, etc…
The stencil will be made from acrylic to be free from moisture, warpage, etc

I have the same doubts about alignment and focus, and this is a reason why I will get a slider with linear rails instead of beams or V-Wheels. Also the bed will be 20120, single piece.
The hard part will be to align the bed perfectly parallel with rails during assembly.

Ps. Can you tell which 3rd party software you use or it’s not allowed?
