1. how to do new tool = current tool ignore tool replacement.


This is automatic with the standard M6, the tool-change - tool-changed handshake is skipped.
So whether you actually need to do anything depends on how the toolchange is being handled.

2. my machine requires tool orientation


Is this handled by a mechanical stop or by encoder?

Sorry for the lost translation
My machine has 10 + 10 tools set to Y0 10 tools and Y4100 10 tools
i have sensor in atc and encoder
My problem with the code is when I restart
program from the beginning and if I worked with T1
the machine again goes into position T1 leave the tool and then take it again

thanks for the bry response

It is hard to speculate about what needs to change without knowing how your system is controlled.

It can't be identical to sim/axis/remap/rack-toolchange as that has no measurement phase.

Do you have this file: github.com/LinuxCNC/linuxcnc/blob/master...ines/rack_change.ngc

Maybe change it to
o<rack_change> sub

M73 (auto-restore modal settings on return)

O111 IF [#<_current_tool>  EQ #<_selected_tool>]
    O<rack_change> RETURN [1]
O111 ENDIF

;(print, rack_change: loaded tool=#<_current_tool> current pocket: #<_current_pocket>)
;(print, rack_change: selected tool=#<_selected_tool> selected pocket: #<_selected_pocket>)
