the problem : Step by step from T2 M6 to cnc starts the correct ... macro ... for starters, please.
< what code, in what file and where is the file located; >
And see the INI entries mentioned over at
forum.linuxcnc.org/qtpyvcp/48401-py3-pro...version-doc-lcnc-2-9
where there are a bunch of commented out lines (#) that are uncommented if you wish to use the probe basic carrousel style ATC tab and included subroutines
but to build a Rack / linear ATC you will want to ignore the existing bits in PB and the above config and build you own M6 remap
a few example of a rack m6 remap have already been pointed out
and I found this one too
github.com/GuiHue/myfenjalinuxcnc/blob/m...cros/rack_change.ngc
based on
"home at : x0 y520 z110 ( left back top )"
you seem to have your machine Z0 at the bottom of the travel (bed height) and the axis going positive from there,
most have Z0 at the top of the travel and going negative towards the bed
lot of existing examples code with be expecting Zo at the top, where a move to Z0 is consider safe (by moving tool all the way up)
