What are the cheapest high speed components to use in a plotter that would NEVER see any side cutting forces. It would only hold a marker, that would be attached using a free floating design that utilizes a spring for the pressure and could conform to a slightly non flat surface <.100" (worst case scenario say if a piece of wood from home depot isnt "machined flat".
I would like it to be extremely fast, 500IPM+, Cheap, and light. It does not need to be the most accurate thing in the entire world. Things like backlash would hardly matter for my purpose with it.
The usuable area would need to be about 30"x 30"x 3"
Parts: (just initial thoughts)
skinniest, lightest, cheapest, bolt together, 80/20 frame.
Unsupported linear round rails and bearings from keling.net
Rack and pinion from mcmaster
solder together hobby pro 3 axis board
steppers
Trying to do this on the cheap, i will be making A LOT of the parts. Just need to know if there is any way to obtain the speed easily. ball screws are way out of the price range of this build.
Thanks for the advice!
