Flip confusion, when does it happen?

Morning All,

LIkely I am overthinking something here. I am creating an EPS blank to make a cast pulley.

My difficulty involves the flip.

Three files, first is the index holes, second is the top surface, third is flip and back surface.

One of the features is a set of three equally spaced holes for the lathe to grip. My problem is the holes have been coming out elongated. I think my confusion is when to flip.

Since my two sides are supposed to be identical, I start with the same cut file top and bottom, insert the flip between… Do I flip the second file at this point or will kiri flip the file before converting to cnc file?

Thank you.

David

thanks for the workspace. this video shows the intended use of flip. selecting flip -> flip flips the part and opens the operation chain for the other side. you maintain the operations for each side separately.

but using your workspace, i did notice that the registration function appears to be offsetting the part, which could be leading to the ovals. i’ll dig into this.

Morning Stewart,

I have another part to my question!

Before exporting the third file which involves the flip and rough, should I manually click the flip and then export or do I leave it alone, assuming the computer will flip the drawing?

you need to export gcode for each flip

Do I need to trigger the flip in Kiri before the export, or does Kiri do the flip itself before the file is written?

you export → flip → export … the reason is that you may decide to just modify and re-export one side and no have “automatic” behaviors interfere with that

Got it, will give a try in the morning. thanks you.
