What a great answer!!
Usually I use the search engines on the forums before asking things that are probably reashed over and over.... but this time I got stumped as I did not even WHAT to ask, what keywords to use.
I am not a newbie in machining, not that I am a machinist, but I a an electrotech in a shop where we build custom machinery for food/pharmaceutical industries...
And the boys find this gantry interesting enough to help me with it and the boss is all for it since we will get a certain level of expertise in this field. Free for him! heh heh!
Thanks again, Luc
