Hi you all!
Hope someone can help me!

Just got me an Emco VMC-100 and have upgraded this with new electronics, pokeys57cnc controller and ofcourse mach4.

But I encounter a strange problem. If I write "G40" in the MDI and run this line, the G41 disapears.
But if I run a G-code  with toolchange, it suddenly comes back to G41. (it stops when "G43 Z15. H10")

This is frustrating because the program then stops because of G28/G30.

What I use is SolidWorks with HSMworks U., Mach 4 postprosessor.

Code used:
(1_SOFT_JAWS_FOR SETTER)
(T3  D=4. CR=0. - ZMIN=-5. - FLAT END MILL)
(T10  D=6. CR=0. TAPER=118DEG - ZMIN=-11.813 - DRILL)
G90 G94 G91.1 G40 G49 G17
G21 G40
G28 G91 Z0.

I've tried changing the values in configuration -initialization values(only use G40)
changed the modal values in the screen editor...

So why is it returning to G41 after my toolchange?

I've added my M6.mcs-file

Sorry for my bad english

made a quick fix...
Think it happens in my tool change macro/script(don't know why), but I put in G40 under each tool change and then voila, it worked!
