    Guys I am having a problem with RhinoCam and Mach 3 G02/G03

    I am trying to cut a CBORE as shown below with the following code.
    The rhinocam simulation shows it cut correctly, however when the code is loaded into Mach3, I don't see the same tool path and the cut is incorrect. The only way around this was to change the arc output setting in Rhinocam and output as lines. However if I am not mistaken, Mach 3 does interpret G2 and G3 codes doesn't it?

    Code:
    G00 G49 G40.1 G17 G80 G50 G90
    G20
    (Hole Pocketing_CBORE 0.3)
    M6 T3
    M03 S13500
    G00 Z1.5000
    X-5.1574 Y0.6252
    G01 Z0.0250  F60.0
    G17
    G02X-5.1573Y0.6250Z-0.1500I-0.0952J-0.0002 F190.0

    G01 X-5.1573
    X-5.1574 Y0.6252
    G02X-5.1573Y0.6250Z-0.3000I-0.0952J-0.0002

    Mach 3.

    The cut piece resembles the Mach 3 path.

    FoxCNC1,

    I am guessing however have you tried switching the IJ Mode setting?

    was not aware of that setting, but when I made the change the path looks extremely large - out of scale.

    Disregard the suggestion if it did not help.

    RhinoCAM is not outputting all the code. What you see in Mach3 is all that RhinoCAM is sending.

    Never used RhinoCAM, so can't help any more than that.

    Let me check / compare code before and after output. Its very weird.
    to rule out that I am not crazy, Mach 3 can interpret arcs and helix?

    Re: Guys I am having a problem with RhinoCam and Mach 3 G02/G03

    Is there a particular way Mach3 likes the code for arcs and helix?

    Here is the post editing options, maybe I am missing something:
    I appreciate the help.

    I believe that the Arc Center should be "Vector from Start to Center".

    nothing works. very weird.
    The only way to get that cut correctly is to output helix and spirals as lines. I have a PMDX-126 breakout. Would that have anything to do with it?

    RhinoCAM is not outputting the g-code. It's 100% a RhinoCAM issue. It's not that mach3 is not running the code correctly. The code is NOT there.

    Thanks I will contact customer service then. Maybe they can help with what is going on with my post.

    Hi FoxCNC1. Are you sure that you selected all MOPS for posting? It looks like a lot of code is missing?

    Yep, doesn't make a different if I select the MOP or the SETUP. I even made a different file just rule out corruption and nothing.
    I am on 2014 from 2012..I don't like how 14 does the "tabs" to hold down parts either..

    Could you upload or send me the 3dm file so I can post it on my end and see if I get the same result?

    yeah I would appreciate that.
    I got a reponse from support, and they are saying that maybe my CNC Controller does not support spiral interpolation. What is the "controller" I thought that was Mach 3? or it is the UC100 USB interface or the PMDX-126 driving my system.. can you please clarify this?

    PM me your e-mail.

    I believe they are talking about mach 3. I have thread-milled with mach 3 in the past. It should be able to handle that. PM sent.

    The spiral moves are not in your g-code.

    Mach3 is the control, but it can't read what's not there.

    thank you for the clarification Ger. Make sense, I was told in the e-mail it is not set up.

    Re: Guys I am having a problem with RhinoCam and Mach 3 G02/G03

    Well I tried getting Mach3 to perform a true spiral and I can't seem to find any Rhino output that will work with Mach3. There is a "circular pocket" wizard in Mach3 that will create the spiral code for you using a series of 180 degree arcs, but that does not solve your problem with Rhino. I don't think Mach3 will support a full spiral without breaking it up into arc events. Here are screen shots of the wizard and toolpath:
