Hey all I know you are SO tired of the same questions. I am wanting to build a d-bot (core xy) style printer. I have stripped my Rapman 3.2 for the parts so i have a bunch of stuff to reuse BUT most importantly i have 3 NEMA23 and one NEMA17 steppers. So i need a design that will allow only ONE stepper for the Z azis to move the bed. What do you suggest before i go and buy all the alu extrusions i need and then change my mind LOL So in short i want a 300x300x400 bed. I could go bigger but i have to wonder if i really need bigger... i doubt it... Anyway any thoughts?
