Hi, I'm currently planning my first dyi 3D printer and got tons of stuff to sort, but one thing that I keep coming back to is the lead screw and BL nut. I hope someone could help me. The printer is going to be large, 500x500x500 active printing area - atleast. With a bed of prob closer to 600x600 in aluminium. All high quality rails. Basically quite heavy. I got recommended to go with a 10mm 2mm lead acme lead screw for Z, but to my question/concern. I can't find a block type anti backlash nut for 10mm (like the one for 8mm in here) and need that for the type of design I'm thinking. Will it be smarter to scale down and go with 8mm screws to get access to standard blocks and parts or just make my own nuts? Cheaper, but strong enough? Everything on the machine will be milled or laser cut, so no printed parts.
