I'm building new cnc machine, my second build.
First machine was from MDF (hobby design and all... )


I learned a lot on fist machine and here i will put build log for second machine.

This is construction for second machine.




More pictures you can fine on my site where it will be more detail text and pictures.

before you proceed the linear rails for the long axis are too low - pls don't do the mistake I have already done.

Why do you think it's low ?*

WOW! Your machine is looking very profesional.
I will be following your progress attentivly.I love the ball screw and rail combo .Looks like a rigid setup,you should be able to make acurate parts.

As i started with mdf machine (my first) this one now for me is unbelievable good.
I did little measuring, and on Z axis ( measured with indicator) i can move axis to 1/10 mm (0.1 mm) and 1/100 mm Mach3 and indicator show same number,

I hope you have seen my build - what happens with your and my setup is that as we start inchreasing the height of the gntry the whole thing begins to shudder when there is sudden change of direction.

I am most worried taht you will face the same problem, then ou will have to reduce the speed at which you are running your router.

pls do reconsider and do necessary changes before its too late.

believe me - you will be much happier.

there are a couple of Australian builds you can probably look at - http://www.cnczone.com/forums/showth...t=71219&page=3

My datacut machine shutters when I change direction. It has a 80lb gantry, so no wonder why.

All I did was add a few cross braces and adjusted the deceleration/acceleration. The shutter is reduced and does not present an issue. Chris the builder of the original datacut says his shutters and it has not caused any kind of a problem in the 4-5 years he has been running it.

This is video of testing milling rosfrai, with end mill 3mm -0.2 in Z

First of all the machine looks great.

Secondly, to my untrained eye the sides of the gantry look very thin compared to the rest of the machine. I'm not sure if it's just me but it looks as if they will flex a bit.

I always wanted to know where you get the metal for the machine. I tried some metal manufacturers but the metal is very expensive.

So can you give some info on where to get some aluminum supports?

Machine is made for wood carvings, 3d and stuff. ALU is hardest material i will use. Rosfrai and other things are just me testing

Fair enough. As I said it looks great ! Good luck with it.

Thanks for the info, also if you dont mind giving some tips on my machine.
