hi all,
I am writing subrutine for automatic tool length measuring, as I have to change 
tool manually on my 5 axis ...

for now I came this far:

o<tool_probe>sub

#1002 = #5223                           (store G54 Z offset)

G49                                     (cancel existing offset if it is any)

G30                                     (to probe location)

G91                                     (incremental mode)

G38.2 Z-150 F300                        (probe fast)

G0 Z5                   

G38.2 Z-10 F80                          (probe slow)

#1003 = #5063                           (store probe resault)

#1000 = -[#1001 - [#1003]-[#5223]]      (calcutaing tool length ~ #1001 is 
previous probed distance without tool)

#5223 = [#1002-[#1000]]                 (correction in G54 Z offset)

G10 L1 P1 W[#1000]                      (Updating tool table)

G90                                     (absolute mode)

G30                                     (to safe distance)

T1 G43                                  (selecting tool)

G1 W0 F500                              (zeroing W axis for kinematics)

o<tool_probe>endsub


So, with this I get correct tool length in my tool table, but problem I still 
have is that when subrutine ends, and for example next line in code is just 
going to Z0, machine goes higher for the distance of measured tool length (G54 
Z variable number is correct Z offset according to new tool length), and if I 
enter in MDI manually  G0 Z0, then it goes to correct Z height, which is on 
same location as before calling subrutine and without any tool compensation.

For test purpose I was calling subrutine with:

G0 x0y0z0

o<tool_probe>CALL

G0 x0 y0 Z0

M30
What am I missing or doing wrong?
