Stell frame cnc 1500X1000. Adjustable table your opinion please

[Jonathan]

Plenty of readings regarding the accuracy in my build log.

Of course that says nothing about what might happen in the months after pouring, if the frame isn't stress relieved...

Bit of difference in size Jonathan it's 2x width and 3 x length.!!

Thanks everybody for your answers
Reading all these useful comments I want to say that I this machine won’t be used to achieve magic tolerances. As Dean said
“…router designed for mostly for wood……… is to be used for cutting aluminum then again the tolerances needed are still low because it will be mostly limited to and probably used mostly for profile cutting”

To be honest I don’t know yet what exactly I am going to use the machine for. I just build a “weapon for hunting” I have never been in the “forest” before with that kind of automated “weapons”. Till now I hunt with catapult (traditional handy tools).
I get involved with many kinds of materials ( wood, steel, alloy) and like to mix them in my construction. That is why the machine is a middle solution (all around machine). That of course means that when you earn in one level you will miss in another level. I think an all purpose machine is impossible to be build as there are parameters opposite each other ( accuracy vs size, stiffness vs light weight and all these vs cost ). The main principal that I try to achieve ( not only in cnc construction but also in my way of life ) is to have the best value for money. So I am trying to achieve the better result with the means and the efforts that I have.
The added value of course at this attempt is your help, even your well disposed disagreements that make me understand things better. In my country we use to say that “sciolism is worst than ignorance”. Many times here in mycncuk I realized that I had sciolism for many aspects that had to do with constructions. Many myths in my mind have been basted especially with Deans help who is something more than an “auto-answer machine” . I could not not mention Jonathans help especially through his Servo sizing software and his inspired constructions, and also I cant forget that the main idea for my machine frame, come out from Syliavskis thread. And all the others that these last months participate to encourage me, correct me, and generally help go one step beyond. I know that I am not too fast in making steps, but I also know that ( for me ) the most important is to make small steps than trivially jumps. This attempt for me is like a trip. I prefer to make the “trip” with a slow train looking “out of the window” , more than ride a fast car and reach the end some days earlier. A Greek poem describes it better. Whoever want to read it (in English ) can find it here

"Sciolism" that's got to be word of the Day Vagelis. (I had to look it up) . . . . In my part of the country it would be called " Talking Bullshit " and yes lots of Sciolism goes on in Forums. .

Dean you know more than anyone that my English are not good
Often i use Google translation



Even (as other say) i use the Greek language very good, i cant say the same about English
So i have no tension to show that i know and use rare words, i just try to find the appropriate word and the only "friend" here is Google. For me was the first time I saw this word (sciolism)
To be more specific the word in Greece is "ημιμάθεια" that come from the words "ημι"=half + "μάθηση"=knowledge, so you could say that "ημιμάθεια"=half knowledge of a subject, and we use that word for people who don’t have a full knowledge of a subject, they know only some aspects of the subject and in the same time they talk as they know everything about it.. Other Greeks that follows the thread I think they know what I mean.

Vagelis your English my friend is better than mine and I know Zero Greek so your way in front.!!

Google gives me two words
#1 Humble
#2 Modest
both words with the first letter capital
You choose which one I should use to characterize you
Lets change «channel». For a moment I thought that we are in a literary forum…
