Heloo,
I am trying for 2 days to write a code just for the arc shape of this piece for my lathe but I receive an error thath the radius to end of arc differs to radius to start....please help me with a Gcode for this shape.
Thank you.

For a lathe arc you need to be careful about radius mode and diameter mode.
Also be aware that in a right-handed coordinate system and a front-toolpost lathe the sense of G2 and G3 is as viewed from underneath.
