Remap of M6 not working correctly

Hello!

I am trying to implement a remap of M6 command as a part of a Biesse retrofit. I am running 2.9.3 on Bookworm.
The machine has 5 tool posts that can be considered as a tool rack (each tool post raises/retracts with pneumatic cylinder and some other bells and whistles but principle remains) as well as 26 vertical drills and 4 horizontal drill heads where drill bit can be inserted on both sides to drill a workpiece from all 4 sides.
Remap is through g-code routines with tool_change.ngc as main subroutine that calls either tool_put_move.ngc or tool_get_move.ngc for unloading or loading tool respectively. These files are copied (with minor edits of XYZ coordinates etc) from previous retrofit of almost identical Biesse that I did few years ago.
I have tool 1 in spindle on startup so I run "M61 Q1" in MDI and then I run M6 T2. Nothing happens - no motion, nothing at all, on very top of Axis GUI I see that it is in tool_put_move.ngc. Printed messages in terminal are shown in attached picture.
I see several issues:
1) (MSG, whatever text) or (DEBUG, whatever text) in the ngc file does not display the respective message in Axis GUI. Only way to get some message so that I can follow the actual execution of code is with (print, whatever text)
2) Line 27 and Line 29 from tool_put_move.ngc are about printing message in terminal. But the move in line 28 is not executed which makes no sense to me as it is straight linear move.

I tried in MDI - those M64 P3 and other commands do work properly in terms of switching the actual solenoid valves

I have attached the screenshot as well as the config. Subroutines are in nc_subroutines folder in config.
I would appreciate any hints what am I missing or doing wrong.

Try t2m6

Aciera thank you for explanation!
Then something is wrong there because this is beginning of tool_change.ngc (which is main subroutine for tool change procedure):

o<tool_change> sub

M73 (auto-restore modal settings on return)

(MSG, Tool change: loaded tool=#<_current_tool>)
(MSG, Tool change: selected tool=#<_selected_tool>)

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

; unload previous tool - if next tool is also in spindle 1, then have to actually unload it first, so second parameter for tool_put_move is 0;
o100 if [#<_current_tool> GT 0]
o101 if [#<_current_tool> LE 5]
o102 if [#<_selected_tool> LE 5]
o<tool_put_move> call [#<_current_tool>] [0]
o102 else
[code continues but it I am now testing with a scenario that "o102 if" statement is true and <tool_put_move> subroutine is called with first parameter as current tool number and second parameter as 0]

I get to the point where a next subroutine is called so I would expect ALL the lines before that to be executed but those (MSG) messages are not displayed.

How do I check of what exactly is wrong?

I did insert G0 G53 X20 Y20 Z80 right after that M73 and the move is not executed. Ok, I will go back now and try your suggestion.

Ok so what I did and what whas the result is shown in 2 pictures attached.
In the tool_change.ngc I added following lines so that the beginning was this:
The result is that in the terminal only the first message is posted. Meaning that it did not get past that queuebuster line. What was expected behavior there? I do not have anything connected to motion.analog-in-00 so I would expect it to read value "zero" and move on...
