After my last video there were many questions about my decision to use lead screws, so here is a post to kick off a bit of discussion around this topic
I have not covered everything yet (No Moment of inertia calculations for example) but I think it will help to understand how fast screws can turn and that this is not a limiting factor, and that Screws can bring a significant improvement in resolution and accuracy, especially with heavier loads as would be seen with a hybrid machine or one with a big heated bed.
