I want to set tool 1 and reference the other tools from there, sounds like what you are doing too. So, after setting tool 1, I next find the offset for tool 2. Are the offsets entered by editing the tbl file with a text editor? I looked a the g-code reference but when I clicked on G43, it looked for an internet connection, that computer isn't connected to the internet. I was wondering what the X and Z did from G43, are they the offset amounts or are they move commands?
Thanks!
