Honestly, I don’t think I followed most of that. Might be that I haven’t finished my coffee this morning, or just a translation issue with you being new to the world of CNC work but from what I think I do understand, it sounds like you’re trying to use the profile tab in Pathpilot conversational to create your part based on an existing drawing?
Assuming that’s correct, you can use the dimensions on your drawing directly with the following considerations:
X = diameter, not radius so be sure your drawing shows the diameters of each section
Z 0.0 is typically set to the face of the bar stock farthest from the chuck and all movements towards the chuck are in the negative Z direction.
There is no way (that I’m aware of) to reference one Z position from the previous position in conversational, everything is relative to the end of the bar so you may have to do some math depending on how your drawing is set up.
All positions that you enter into the table are based on endpoints, so if you have a radius from one diameter to the next, you need to know where that radius starts and ends in X and Z. The center point is not used.
Threading is a separate function from profiling. You would want to turn the starting major diameter in the profile tab, then create a threading program in the thread tab. You can append the thread program to the end of the profile program if you want, or you leave it as a separate file.
