Hi All,

I have two bridgeport interacts with TNC 145 and have been looking at CAM software for a while now.. downloaded a few trials etc but have never got further than that.

Anyway, i was looking again today and realised Autodesk do "inventor HSM" and the 2.5D software is completely free! Perfect as i already have inventor.

So, i have had a good play around and drawn up a few tool paths, found a post for tnc 155 which will hopefully work, post processed the tool paths and im happy with how the programme looks.

...this is where i need help, i have no idea where to start when linking the computer to the machine and transfering the programme. I have a rs232 cable & serial adaptor which i have had much success with on a harrison alpha lathe, does anyone know of a step by step guide to linking a 145? I've read a lot about 151's but cant seem to find much for the 145.

Any help would be greatly appreciated and thanks in advance.

Best Regards,

Jack
