Hubert, there is also the option of integrating a tool length sensor. With the first tool set the home position of the Z-axis and use the tool length sensor to record a tool-sensor offset. After changing the tool, go back to the tool length sensor and determine the tool length, minus the offset is the new home.
This does involve some extra G-code after a manual tool change but it is a great way to prevent problems due to changes in the tool length. This is the way I like to use a tool sensor but it is still not done... I still use different files for different tools but this means I do make mistakes from time to time: Forgetting to load the new program, wrong order of programs or just forgetting to set Z=0 with a new tool. There is, as far as I know, no way to use MDI during a program. If it was possible then how would EMC know how to move back to the last programmed position/ Rob Hubert Bahr wrote: > Is there anyway to use MDI during a program run.
