2D Plotter Designed and Engineered from Scratch
The orders are slowly starting to arrive. I've also 3D printed all the parts. I was able to connect the first motor and wrote demo code to test its movement.
Just loaded all the parts needed for printing into Cura. I'll be starting printing tonight or tomorrow! Come join me live on Twitch on Tuesdays as I stream: https://www.twitch.tv/travis_the_maker

Today I decided to switch gears and setup a little circuit that would test all the components (2x stepper motors, input mechanism, screen, brain) that I'll need for the plotter. This was the result - a joystick that can increase, decrease and reset values; a screen to display the current value; and a stepper motor to position itself (0 = start, 100 = half turn, 200 = full turn) where that value is.
It looks like I made no progress, but I swear I did! I now have the foundation for motion in both directions. The first stepper motor (which controls the direction of the other stepper motor) will be with a threaded rod. The second motor will use a belt to move the painting apparatus (aka a pen, marker, etc.) around.
