I also find that typing "T<n>" as a code, either in the program or MDI, does not seem to change the tool number.

use     T0101    for toll #1 in the MDI

When I start my Mach3 Turn,

I randomly get one of 3 different splash screens

That is what you originaly posted.
Then you reply
I have only one screen set, it's not that which is different between launches.

Me confused ...........

Pics of screens

Aha!  Just checking all 3 of these are in the "Bitmaps" folder (not surprisingly), so for some reason the system must make a random choice of which one to display.  Not a bug but a "feature"?

And some more progress.  I have made the config changes suggested by TPS and checked that my M6start macro contains the correct instructions.  The M30 and Rewind issues are fixed, and I find that if I put a "T010x" instruction in the g code it does select the right tool offset though the tool number doesn't change.  I guess there may be a format issue with the tool no. DRO display box? - will check that.

The rotating "splash" screens are a normal part of Mach.

Thanks Mike!  A feature then.

Where did the splash screen set come from?

Rich, as I said, the splash screens are in Mach3/Bitmaps.  It is not a "screen set" in the Mach sense, but a set (i.e. collection) of screens...
