The ball screw fit for the linear guide

thingiverse

I spent a considerable amount of time deliberating whether to construct an entirely new XYZ machine or upgrade my existing Delta, which I'm not particularly fond of due to its difficulty in adjustment and lack of precision. One of my friends recently built a linear guide version delta with three ball screw pairs, and it looks impressive. I decided to design a ball screw specifically for the linear guide. Initially, I was planning to use the 1204 screw, but I'm concerned that its length might be too short. My stepper motors have a resolution of 1.8 degrees per step, which translates to 200 steps per rotation or approximately 0.02 millimeters per step. Additionally, I've implemented a 1/16 subdivision system, allowing for a precision of 0.00125 millimeters per division. To move the machine by 0.01 millimeters, it would only need to advance eight divisions, ensuring that all movement is calculated into whole numbers of steps. With the design complete, I'll be purchasing new 2020 aluminum bars to upgrade my Delta. Fingers crossed that everything goes smoothly without any issues.
