Im new, am a 3D designer. Need a New cnc machine and need advice and guidance

[FlyHighRC]

Hey guys, Spent most of the day researching CNC designs. I am now pretty sure I want to design my own. I Feel i am able to build this machine...I have a decent workshop filled with tool and my grandfather has a model engineering workshop with manual mills which could come in pretty handy.

The only issue im having is pairing up the hole sizes in the rails to be able to fit the extrusion. This is becoming pretty frsutrating as I cant seem to find extrusion,rails(supported round and linear) that want to fit eachother easily.

Could you guys point me in the right direction of parts that are almost plug 'n' play please.

I also found this CNC Kit it seems pretty good to me but im not the expert here haha. If you could help Id really appreciate it

No extrusion then aye...bummer, look much simpler haha

Ye it can be simpler but not has much as your probably thinking and it will cost at least 3 times the price of steel. I build a machine that uses HD profile but it's used in a very specific way and using thick aluminium plate machined to match so it's not exactly DIY or cheap and you need CNC machine to help build another.! . . Chicken and Egg.!!

Steel will be much cheaper and far easier for first time DIY build.

is the above link good enough for the steel frame?

Im hoping to base the machine loosly off of this guys machine...though due to workshop size and the way this machine works it would be difficult to anything over 600x600mm cutting area...just because of the fact the table slides ather than a moving gantry...which to me looks like the better way to get the job done.
