Is that all of it?

Try:

Code("G53G0Z-0.5")
While IsMoving()
sleep 100
Wend

Code("G53G0X24Y1")
While IsMoving()
Sleep 100
Wend

I think the answer is in the M6end macro. It deals with safez IF z >safez then it does a traverse move and that may be at Frate IF Z=< than safez then it moves at rapid rate.

Might want to check that. It may explain the different rates.

REM The default script here moves the tool back to m6start if any movement has occured during the tool change..

x = GetToolChangeStart( 0 )
y = GetToolChangeStart( 1 )
z = GetToolChangeStart( 2 )
a = GetToolChangeStart( 3 )
b = GetToolChangeStart( 4 )
c = GetToolChangeStart( 5 )
if(IsSafeZ() = 1) Then
   SafeZ = GetSafeZ()
   if  SafeZ  > z then StraightTraverse x, y,SafeZ, a, b, c
      StraightFeed  x, y,  z  , a, b, c
else
Code"G00 X" & x & "Y" & y
end if



   
That is how my unmodified m6end looks like

but it does not move at rapid rate that is whole point. it moves at previous feed rate to last location within last tool path.

I think I found bug in my script for probing, it sets feed rate to prior feed rate.

Ok now that I found where it comes from and tested it.
I would like to add command to my script f=rapid feed rate
How would I do that?
