Week 2 Laser
|
|
|
|
This week we focus on tools, and we learn about images.
|
|
|
|
1. Coordinate system
|
|
|
|
Last week we used the Absolute Coordinates system. This week we get some practice using the *Current Position*, as well as *User Origin*.
|
|
|
|
Additionally, we will learn how the *Print and Cut* feature can be used to recover cuts that may have gotten out of alignment.
|
|
|
|
2. Tools
|
|
|
|
We will create a *speed/power grid* that we can use any time we are working with a new material in order to tune our settings. This tool will help us to find pleasing levels of "grayscale" that we can use in our fills.
|
|
|
|
Learn to create a *settings library* that you can save and keep for your use.
|
|
|
|
Exercise: Fake Transparency
|
|
Overlap two fills. Learn to create a boolean difference between them. Use selections from your speed/power grid to make it look like the overlapping fills have transparency.
|
|
|
|
3. Images
|
|
|
|
Learn the difference between grayscale images and dithered images. Learn when is the best time to use each.
|
|
|
|
Dithered images are technically black-and-white images that "fake" grayscale via the patterns they employ. These are good on all materials, including those that have a very narrow flashpoint, such as acrylic. (Grayscale does NOT react well on acrylic) |
