    Help request

    I have an old Fadal that I am trying to run a simple interpolation program on with cutter comp.

    Here is the entire program:

    o5434
    T3M6
    G54 G17 G90
    G0 x0 y0 Z0
    G41 X1. Y0 F30. D3 G1
    X-1. Y0 I-1. J0 F30. G3
    G3 X1. Y0 I1. J0 F30.

    The machine reads the G41 line, makes a linear move to that point then stops.
    However, if I set the tool diameter for D3 in the register to 0, then it will execute the entire program.

    Is there anything wrong with this code?

    After this, I will need to figure out how to interpolate in the G19 plane with cutter comp. I'm just starting with something simple just to understand all the basics.

    Any help will be much appreciated! We are looking at buying a right angle head for the fadal in order to do some horizontal thread milling on 24 inch long plates.

    Thanks

    code looks ok.... but..

    your nc example is missing the remaining lines.
    ... normally.. most nc controls look ahead when using cutter comp, so to calculate the continuing adjusted path.

    try posting the full nc code up to the G40. so we can give a better diagnosis.

    Re: Help request

    What is the center coordinate when the tool stops?
    Does it alarm out also?
    What is tool radius?
    Does it work with G42?
    Replace G0 x0 y0 Z0 by G00 X1 Y-1 Z0. Does it work ?
