Give this a go... please be careful as it needs to be tested before you can rely on it. Also Mach does not display the stock correctly but the cuts look ok from the DROs. I would recommend cutting air a few times before using it to do any work.
All the other wizards work with "Reversed Arcs" checked. This one seems to require it be unchecked - otherwise the arcs look a mess. Anyway, it cuts a convex arc (like OD Arc 3). Also the Z Start and End (May be should be changed to Z Centre..) are swapped.
The gcode file puts out TyyyM6 for a tool change. The M6 needs to be omitted.
