Linking Inventor HSM to Bridgeport

[jackpat]

Thanks for quick response!

Heres an update: -

When establishing connection in TNCremo, its giving me a "no response from tnc" error...? I had the cable made up for me, it works perfect on the lathe.

For now i am programming in office, dropping files onto memory stick and using them in tncremo on laptop in workshop. I will make up a long cable once i get things running :)

Programme has a .H extension (145 cant convert to G-code i believe), so on line 0 i need to write "1.H" and the same on the last line?

Baud rate is set at 2400.

Thanks for the help! - look forward to hearing back.

Program format is absolutely vital - other wise it's ignored - here is an example pasted - don't seem to be able to attach as file :(

You have read the bit about setting the TNC 'mode' haven't you re EXT FE etc - sounds like your cable or setting are wrong rather than the pogram though

Yeah i think it sounds like the cable, i've been told pin layout will be different on the one i have... So ive just been to maplins for the bits to make up a new one :).

The programme the cam has generated looks absolutely fine.

Cheers,

Wired cable up 2-2, 3-3, 5-7 and still no joy. Will try with 4-8 6-4 7-5 and 20-6 aswell and see how we get on (wiring from post on cnczone).

There is a Heidenhain publication called

Data Interfaces
of HEIDENHAIN Devices
Service Manual

Google it and down load - if you can't find it pm me your email address and I'll send you a copy.

It describes all the parameters and setting for the various controllers for RS232 comms - this is a small extract that is probably in your manual anyway but it has far more detail

[jackpat]

Andrew,

How funny, i started looking through the interfaces manual just as you posted. Hopefully i will have some joy with it...

Cheers,

Jack

Hi Andrew,

Managed to get back to the bridgeport today, i rang heidenhain for pinouts so cable is sorted. TNC server and controller coming up with no errors, however i can only send a programme to the laptop from the controller! Which is the opposite of what im trying to do. Whenever i try to send the opposite way, TNC server just says "receiving file" for a couple of seconds then goes back to doing nothing.

Any ideas?

Cheers,

Jack
