Hi and thanks for your help.

I have some problems to understand why sometimes i cant put to zero correctly and i need to reboot all for start.

I doesn't understand correctly the tool height gcodes and ATC M106 tool changes/operations.

I have all tool heights sets in tables (i have one macro for measure all tools and work good).

Anyone can tell me the correct G i need to stay for set to 0 the tool with atc manually, some questions are:

I need to stay with tool g43 enabled when zero with a tool
If i change manually i put m106 t1 only i need to specify H1? (sorry im very lost, because this problem only occur some times and all is when i change manually tools or after use a gcode i think).
g53 or g54


One example of my Gcode i use and work correctly (but maybe this affect when i change 0).
