Hello, I plan on building a robotic gantry to do some light duty material handling (less than 10 kg) with an X span of about 3 m, I intend to use V slot components. I'm looking for ideas on what I should use to drive the X and starting to wonder if I'm over complicating things with regards to precision. All the information and threads around here pertain to CNC and 3d printing; I don't need that same degree of precision. I need to the mm rather than .001 mm, plus the gantry will always return to a home position after every stop (goes from A to B to A) where it could be zeroed out. My problem is I get all caught up with the cool stuff like servobelts and roller pinions when a simpler, cheaper solution would work just as well. So what should I be looking at to do 10'?
