Hello everyone!
I'm from Finland so you have to excuse my broken English :)
This is going to be my second machine build so I hope that I'm not going to do the same mistakes this time.
Previous build: Svenska ElektronikForumet • Visa tråd - Daniels lilla cnc fräs // ny skärvätskeannordning
It's in swedish but google translate might help or you could just look at the pictures ;)
So on to the new bigger machine, it's going to be built of epoxygranite and will be using star/bosch and THK linear rails. The ballscrews are 1605's from lmb2008 at ebay.
The work envelope is going to be around: (mm)
X: 490
Y: 305
Z: 334-490
All axis in zero:

And in their maximum position:

This is an rather old drawing but sketchup is a real pain to work with..
I'm drawing up a version in solidworks at the moment.
Here is all the screws and linear rails i'm going to use for this project:

Some blocks didn't make the shot but you get the point :)
The bearing blocks for the ballscrews feels very cheap but after some cleaning they feel at least ok.
I did this to get my inspiration flowing and hopefully get this project done:

I almost forgot about the electronics:
I'll be using 1.5NM (1NM @ 1000rpm) steppers for X & Y but I still need to find one for the Z axis. I haven't decided on any bob's or drivers at this point.
It's always fun with some feedback so feel free to leave a comment or two ;)
