anyway, if you will not find any errors in Mach config you always can use postprocessor remap.
remap("G02"->"G03","G03"->"G02");

See gcodetools post-processors for more info.

Many thanks for your help

You were right about my Mach3 settings. In Mach3 general configurations I had 'IJ mode' set to 'Absolute' you have to set it to 'Inc'

And now works beautifully.

Great

Yeah.... I think we should add G91.1 and G90 to the standard header. To ensure that this problem wont come up in the future.
