Im having problems with my hardinge 3 axis superslant lathe, Its been troublefree untill recently , now it appears that i need to replace one of the many boards in the fanuc gn6tc controls at a cost of $1700.00 . Im thinking why piss away money on 20 year old technology when i can retrofit it and keep her going another 20 or more? Can anyone recommend a good retrofit and what should i expect it to cost if im just buying the parts and retrofitting it myself ?
