Help With The Siemens 840D Tool Retract

Hi All,

Could one of you smart people answer me a question please?

I have a Siemens controlled machine that skips the tool change when the same tool number is requested via the program,
The Vericut simulation shows it different, It simulates the tool going to the home position each time.

I've found the sub which looks like this :-

%SPF300
D0
IF ($AA_IM[B] <> 0.00)
   G00G90Z351
   G00B0
ENDIF
G90G00Z490
G90G00X-134
G90G00Y175
M6
M17
;

Could somebody please show me how to mod this to simulate correctly?

Cheers in advance

Alan,

The subroutine you included checks for the B axis position being something other than  zero.  It is not checking the tool name/number.  Something  else must be doing that check.
