Key hole app

I tried using the Key hole app but it does not make a keyhole. All I got was a slot . What did I do wrong?

Did you use a keyhole router bit?

I did use a keyhole bit. What I didn’t do was set the depth correctly in the settings.

If I’m going to use the keyhole function I have to repeatedly check everything, not only the numbers I’ve inputted but also the piece is secure. It’s easy to underestimate how brutal the slot is made. I now run it incredibly slowly.

Why not just save the g-code and use the same one every time?
