A bit of a stupid question, which shows my ignorance in NC coding. These imperial programs I am using have a tool change callout G43. This line is causing me an issue on some of the latter programs I am running, as I have limited Z axis travel and don’t have the luxury of allowing the spindle to go to Z1 an inch above the work piece. It’s weird why the programs have tool changes specified as it’s all one tool.

Can I simply remove the line from the programme ... or do I just modify it to say Z0.25. I am not clear whether the program refers back to the tool change or not. I have searched the program and it only has one g43 callout.
