Cutting Cogs for Wooden Clocks

[Oldbill]

I am fairly new to the cnc world and I just finished the Rockcliff router and things have turned out well.
My question is that when I draw a clock cog on autocad and import the file to Mach3 software the G code is generated and all seems well until I acutally run the program. The toolpath seems to follow the inside of the cog and not the outside. Am I missing something in the G code to compensate for this?

Thanks

Yes, read page 9-1, 9-2, and 9-3 in the mach 3 manual. Your on the wrong side of your cutter path. Make sure your tool table is set up properly with the correct tool diameter, and mahe sure in your tool change you are calling up the correct information. use a g41 to turn comp on and a g40 to cancel it in your program. Hope this helps, Pat
