« on: September 25, 2012, 09:51:52 AM »
I know I have read some posts on here re tool change and codeing I have had a good and I mean good look through post and done a few searches but sofar nothing.
Does anyone know of a tread or remember one as at the moment I am having a few little issues and wanted to look through old post to see how others were doing it or if its my post doing the code wrong?

Doing a search for radius comp or height comp should bring up something but there is also the explanation in Mach itself when you click on the G Code button on screen.

G43H* is all you need,  what the G43 does is look at the tool table for the length offset that you have called.
So for example  G43H1   would look at the tool table for tool 1's length offset and apply it.

Having a G49 in the code will cancel the offset and set to zero offset.

If thats not what you are asking then just shout.
