Hello, I had istalled a factory new VF-7 in january and since the start it never worked good; it came with a table with steps on the sides and curved down to the center; i managed to get the assistance form the HFO that installed it just at the start of this week, and anyway they decided to face the table, because it was a long way out of spec (it was so not flat that if you tried to slide a granite block on top of it it gets caught in in the t slots); after facing the table it resulted in an inverse banana compared to how it was; and the tech guy that came also noticed that if you touch with one hand the table it moves down considerably and if you pull it up goes up by quite a margin; furthermore the renishaw toolsetter gives different lenghts up to 0.066mm and 0.01mm in diameter variance even if the measurements are repeated back to back in less than 2 minutes timeframe; furthemore i have done a testpiece doing bores and squares and with the same tool the squares are good in dimensions to the 0.002mm while the bores are always smaller by 0.03mm more or less but the center it is good to the 0.002mm; they don't know where to start, and it doesn't look acceptable to me to have all these problems and not being able to use the machine because right now it's useless, what do you think guys? what could be the problem?
