I worked on the X-axis system today. I tried a lot of ideas, but I think a pancake stepper motor with a belt drive is the best option becuase it should be smoother and more accurate. I also made a servo design, but the shape did not work well and the whole setup was alot too big.I also CADed the electromagnet so I could see how it would attach to the moving carriage. This helped me check the spacing between the belt, motor, pulley, and magnet holder. The hardest part was fitting everything into a small space while still making it strong and precise. Next, I want to test the movment across the board and see if it lines up with each chess square.
