Well, I can report progress! Today I downloaded the latest Mach3 lockdown version, uninstalled the pervious driver and deleted all the files having first taken a backup of the config xml. Re-installed Mach3, now find the rather than having to load the Shuttle plug-in it is part of the release. After carefully checking that the Shuttle Express works as intended following the instructions, I set it up and try it out. Now works much better but I still find that the X direction it moves in response to the jog wheel is counter-intuitive: the crossfeed screw turns anticlockwise when I turn the jog wheel ckockwise and vice-versa! Z feed works fine. In the latest version the check-box option to reverse the feed has been removed as well!
So question: is there a way to fix this please or do I have to get used to it?
Thanks,
John.
