    What's Wrong with this Arc G-Code? Trying to make an arc in Z

    I am wanting an arc segment in the YZ plane with a 100" Radius in the Z axis Picture a huge smiley face or an upside down rainbow. I want it to start the Z plunge at Y24 dive in with the arc and have Z exit the workpiece at Y9.3

    Here's my Code segment. What am I doing wrong?


    G00 Z.1
    G00 X9.25 Y24
    G01 Z0
    G02 Y9.3 Z0 J-7.35 K100
    G00 Z.1

    I'll try it in my editor. I'm not sure my old G-Code interface will understand G19 though. So what's going wrong there with my original code?

    EDIT: just tried it in an editor and I'm getting two HUGE circles not just the sliver of the arc I'm looking for. Also, I don't think G19 works on my machine.

    Ok, it actually does work. Preditor Editor didn't like the file but when I tried it on my machine, it works just fine. Problem solved.

    Ok got it to work as is. For some reason Preditor Editor didn't like it. But the machine ran it just fine.
