Art,
What is the tolerance bar, is the the slider in between the two screen monitors?
Regarding the camera height, how close is good enough? If I measure 8 inches and Mach3 reports 6.5, is that close enough to get some accuracy?
As implied above, I have an 8 inch (200mm) camera height. I will try a larger block, but I think the short focal distance will make it impractical for the block to grow larger then 65 mm.
Have you posted any version revisions yet?
Thanks,
Dave
