CNC plasma gantry
thingiverse
I built this with a little inspiration from "square tube linear guides". I needed a gantry that would fit a 2x2 stainless steel square tube because the old one I have will not fit the racks I bought. The link is to eBay were I purchased the rack and pinion (https://www.ebay.com/itm/292211784802). I have not completely put this together so I'm unsure if the tension pivot will function properly. the only steel I had was 1/4" plate so this is designed for that thickness, its a little over kill for a plasma cutter but it will work.
