After learning so much about 3d printer, I am excited to continue. My current printer can make some pretty nice things, but it is limited in the size that it can make. There are many things that I would like to print that it just isn’t quite big enough. After doing some research of printer designs, I have decided to build me a CoreXY style printer. The first step was to design the XY section. There will be two stepper motors with two belts and pulleys to control the XY motion. I am building it out of 2020 extruded shapes but instead of using aluminum I am trying to do it with all printed pieces. This may not work, but it is worth a try.
