Hello,

I am looking to Gcode a basic arc, however I have no idea where to start, I have written taper, and (thanks to Graham) doubble tapers so I suppose an arc is the next logical progression. I know they use the I and K values however this is the limit of my knowledge.

If anyone has a straighfoward example they could share or code somthing up quickly that would be great.

I am useing a small sherline cnc lathe.

Cheers,

Andy
