Thread: Heidenhain TNC 151b & G codes
01-07-2005, 08:10 PM #1
I understood that the Heidenhain TNC 151 controllers obeyed Heidenhain's own codes and not normal G code, BUT I've seen an oblique reference in an online operators guide to being able to enter normal G codes, and there being a clip on overlay held on by magnets to customise the controls keyboard (presumably just the legends).
Anyone any experience of this - is it only certain firmware levels that do it - spill the beans !!
The manual in question is at:
Open the TNC 151B User manual and search for Programing in ISO codes

Yes Andrew there is a small keyapd that's just a series of overlay buttons that press the ones underneath.
Only difference is they have ISO codes on the top set.
You select ISO codes by a series of key presses,
See page 259 of the book.

Andrew,from the 151 on there is a clip on overlay which allows you to programme in G codes and I know a man in your neck of the woods who has one for a 151 as fitted to a Beavermill.I`m not sure if it will fit the Interact.
Before you spend money you should try the Heidenhain control as is.We have a 150 on a Beavermill which my son who had never before programmed anything mastered quite easily.

I am familiar with the TNC151 as they were used on the Bridgeport Interact machines. The G and M codes were a little different from what Bridgeport used on the BOSS machines and what Fanuc uses. Also you have to go to the MOD key, they cursor up/down to get to the page which gives you the choice to switch between conversational and G & M codes. If my memory serves me correctly, the control will reboot and convert whatever was in memory to the current mode you have chosen.
