hi jazz

I was suggesting options for 4ft by 4ft table, up to a full size table, and just trying to give him a general idea. . If you read my post, i had suggested that, i also said i did not know enough about R&P.

If price was not an issue from him, i would say 25mm rails and screws and servoes, but he is clearly looking for cheaper options, and it is that i offered advice on, but he clearly want to have a crack at this on the cheap. and it is doable, i was just trying to help him understand, that he can not go cheap on motors and drivers. I do have some experience with that type card

ther are many wrong approaches to machine building, but there are also a few right ways. not just one. If it was like that, you would just point him to this thread, and say build that

Well engineered, well built, and he lists what he would change

But he is clearly looking for cheap options, and wants to hobby build. and remember were the hobby built cnc machine started, For me, a graph plotter with a drill strapped to it, 1989/90 machine running it was amstrad 1512, and we had to write the actual code that run it, My current main hobby ( robotics/electronics ) and previous hobbies ( UAVs and RC stuff, kart racing ) all work on very fine tolerances, am used to having to get things a lot more refined than is needed for cnc design, granted, on a smaller scale. I do clearly mark any post that i have given advise on thought that i am a newbie,
