My first 700 x 500 x 300 Mill/Router machine

[Lovre]

Hi guys,

This is my first post.

I'm planning to build my first CNC machine, it should be rotuer/mill machine on which I would do some work on wood and if possbile on aluminum - for rest it seems that budget must be huge.

First parts are ordered , SBR16 supprted rails , stepper motors , ballscrews (SFU1605), cheap chinese stepper controller up to 3.5 amps, breakout board ...

Now I have couple of questions ...

1) I would appretiate if you would take a look at attatched picture and give some comments .. I plan to use aluminum 100x10 mm for building gantry, or at least most of gantry, cause it could that 100 mm is too narrow for some parts of Z axis. But I will deal with it later.

2) Ballscrew end support seems to be really expensive(at least 160 usd for 3 Axis, BK12 and BF12) , is there any cheaper way of doing this ?

Thats all for now ... Thanks and I'll keep you posted ... I hope to finish this in next couple of months, I'm just waiting for a lot of stuff to arrive and it seems to be taking a long time from China to Croatia :)

Kind regards
