Hi Forum,

I am trying understand G43 (tool offset) and ant to ensure my interpretation is correct (et. a sounding board), from reading this is my take (ope for guidance/correction):

- I set stock surface Z (z zero - mach 3 script), usually done with the first tool identified in the code as a touch probe...
- This is 'stored'
- on tool change G43 offset adjust for tool height etc.. (which is ok for auto tool changer, which I dont have)
- this is where everything goes pear shaped

When i do a tool change I use the script to set Z (touch tool script)

so I assume i need to either ensure G43/44 type code on my post processor is removed or cancel the G43 (e.g. G49, HOO or M30 - although i am not sure which would be best of these ?)

any pointers are welcome

If you are using an auto zero script for each tool, than you don't want any G43's in your code, as you aren't using it.

ok - that was my assessment - but i wasnt sure i was on base - thanks for the info
