I am from Romania...
The thing is that i work at a marble and granite manufacturing factory: we make all types of items from these natural stones: stairs, vases, flower pots, tiles,monuments and tombstones... And the boss has purchased 2 CNC Router machines from China, the 3D design software is a very old version of ArtCam an the machine control program is NCStudio (also from 2000 or 2002).
My job title here is Production Operator - i register the documents for the entering and the exit of the proucts, in order for the sales depart to make the final paper bill. So at first sight you must understand that I should have nothing to do with programming andd machining the CNC Router.
Even so I seem to be the only one here to really understan english and to be able to learn a design program... and so I did. But now a brand new problem: after I establish the exact size of the material (in mm) and I center the model to carve, i save the toolpath and then load it in NCStudio.
And there comes the problem: if i establish a X lenght of 400 mm it goes 480 mm...and also on the Y axes. Otherwise the machine is following my instructions.
What might be the problem and how could i solve it?
P.S. I am no specialist, a Level zero user at the moment but i have made some work that weren't all that smooth but looked just fine for a first or second trial
