We’ve had discussions on the forum about the actual dimensions of the Glowforge product, and of materials. Of interesting note was the article sharing an “unscientific survey” in which 1/3 of those polled were unaware of the difference in actual measurements from the nominal dimensions in which lumber is usually measured.
The Glowforge is going to be used by many people who may be effected by butting up against the very edge of some measurements. We’ve already seen issues with dimensions changing from the original crowdfunding campaign to the actualized product. There are actual measurements of materials that may give us grief (1/4" acrylic is not exactly 0.25" thick). We’ve also seen issues from the metric/imperial measurements, some of which @palmercr has brought to attention.
How might the actual measurements of materials and the machine itself cause problems with users projects, and are there ways to buffer these problems for even the most unexperienced of users?
Measure twice, laser once?
