I have a Bridgeport interact 1 series 2 fitted with a Heidenhain TNC150 controller. I now have a need to do a lot of contour surface milling which will exceed the controllers memory. To my dismay I discovered the TNC150 will not accept 'drip feed' data from an external source. I have looked about and found a Heidenhain TNC151A control which I am told can do the job - transfer lots of G code data from the output of my CAM program - Can anyone please confirm this to be true ? Any other info greatly appreciated.
