Rostock max is too small...

[DavidF]

So im thinking about building something bigger. Delta of course. Question is how big can one be built on the nema 17 steppers? I was thinking about something along the lines of a 24" radius and 30" z, keeping the weight down the best i could would this be possible? Ive browsed over some stuff on openbuilders.com and would be using thier 20/40 extrusion for the frame work and printing the corner brackets.
Any advice you can give me would be very welcomed.

So timely for this article to appear recently in my twitter feed. I eventually want something like this too.

Though, the pictures don't make the print envelope seem as big as they say it is...

Still to small, plus i woud rather build it myself. Mostly questioning the resolution of the steppers and electroincs if i did build something this size.

Have you thought about how large this machine will be? The arms to do a 24" diameter platform will be about 24" long, add that to the 30" build height(sine, cosine etc) and you've got a 5' tall machine.

It'll be neat though!

You could go with a board that has step/dir pins accessible(smoothie, etc) and use off-board drivers to run Nema 23 or 34 motors or even servos.

Now you're talking. I seriously want a part-daddy. Maybe a part-daddy junior.

I've been pondering a cartesian, with a build area of 36"x18"x12". Maybe 36"x24"x18".

Im kinda hung on a delta. would also like to keep things in budget and run nema 17 steppers and inexpensive electronics. Havent really put any thoughts of direction into this yet, just know what I need as far as build envelope. I could possibly tone down the x-y a bit which would keep me from pulling my hair out. But whats the fun in that?

i was just thinking about my next printer build having a build volume of around 24 x 30 and to keep the weight down i was looking at trick laser they some parts you might want to look at. you could use carbon fiber arms, and maybe more teeth on the motor
