Graham,
Why do you put the g41 code where you did?
When I copied your code and took mine out
it worked like I thought it should.
But why?

You have to start the G41 on the first feed move. Rapid moves vector so the start point is wrong.

You can reverse the direction by setting the X & Y scale to -1, beware that everything will be reversed.

You can put G51 in the program to reverse sections and then G50 to revert to normal.

Man you are making my grey matter work overtime.  ;D
