Hello again,
I have since called the laser manufacturer and was told that their software can accept a DXF file. The person that owns the laser engraver is not a very computer savvy person. For that reason I was trying to make it simple for him. I do realize that what is on the screen represents a bitmap. The suggestion to draw a square around the encoder pattern suits the situation just fine.
He will understand that it is a 3 inch square and will adjust the output accordingly. Also I understand that it will not be exactly 3 inches. If he gets it to plus or minus 1/32 that with be sufficient. Whatever the error is it can be compensated for. I'm very grateful for all the very thoughtful comments.
If this does not work (and I think it will) I will go over to his place and show him how to import a DXF file.
Thanks to everyone,
Bob B. |
