This will be a long, drawn out thread, as I've barely got an idea what I'm doing, and don't have the budget to buy everything at once... but I'm jumping right into the deep end, building my own CNC router. My goal is to make it as light as I can, so I want to build it out of extruded aluminum. Here are the parts I've already ordered: 2 x SBR16 850mm 16mm Fully Supported Linear Rail Shaft 4 SBR16UU Block | eBay 1 INA F 303363 CNC Linear Rail 1 INA Ball Bearing Block 600mm x 25mm | eBay Wantai CNC 3Axis Nema17 Stepper Motor 4000G cm 1 7A Driver 1 7A 36VDC 128MICRO | eBay Nema17 stepper motors SHOULD work if I can keep the gantry light. I still need to make plans for my build and figure out the lead screws I'll need... If anyone else has built one let me know. I can use all the help I can get. I might wind up ordering a Gecko G540 some day, but we'll see. For now I'm going Chinese parts, I've read good things about them, and can always upgrade in the future if need be.
