I have a Mazak VTC-20B with M Plus controller. When I do3 D or anything with lots of g code, I get parity errors multiple times throughout the process. Also, the movement is slow and interrupted. Unless I turn the feed way down. I am using a dnc device to feed the machine through a cat 5 cable into serial port. How can I improve this situation? Other than buying a newer machine? Thanks in advance!
