    Hi Kumar,

    Great. Thanks for posting back.

    If you find time please try to troubleshoot why you weren't compiling the code. Some things I sometimes do is to put an intentional error in the file that I'm changing. If there isn't an error when compiling I know I'm changing the wrong file. Also check the timestamp on the executable to see that it has actually been re-built.

    Regards

    Hi tom,

    Thanks

    Actually timestamp on the Kmotioncnc.exe file was not changing. When i was trying to compile the code earlier but after you compiled timestamp was changing. How is that even possible.?

    Thanks

    Hi Amit,

    Were you compiling the Libraries (BuildAllLibs.sln) or the Examples (BuildExamples.sln) ? KMotionCNC is an example Application not a library. The Kinematics is part of the Libraries.

    Were you looking at the correct Debug or Release directory depending on whether you were building the Debug or Release Configuration?

    Was the build successful? Did the build compile the file?

    Regards

    Hi Amith.

    How are you, Just know i was speaking to Mr.Naveen.
    He told me that you are facing RTCP problem with your controller.

    Need any suggestion call me.

    Hi Tom,

    I have successfully built and complied the files.
    I am able to turn off the RTCP using G49 but when i try to turn it back on by using (G43,4 H1001), I am not getting the correct results.
    The RTCP is not turning back on in the same state that we turned it off at. I feel that there is some problem with the tool height optimization.

    Awaiting your earliest response.

    Thank you,

    Regards

    Amit Kumar

    Hi Amit,

    What happens? What State is different? What Tool and Length was selected before?

    Regards

    Hi Tom ,

    TCP seems to be working fine by using G43.4 H1001 command.

    It is optimizining according to the tool length in tool table.

    But the problem we are facing is the value mentioned in tool table has to be in inches but the optimization and DRO shows values in MM.

    For example My machine coordinate is Z110 at some point and we are taking tool length of 36mm and value of this tool height i input in tool table of H1001 is 36/25.4 = 1.417 inch.

    So after i turn on G43.4 H1001 command. TCP is working with Z74 (110-36) and it is correctly optimizing.

    But in Machine coordinates (Orange) it is showing Z110. And in Work Coordinates (Green) It is showing Z108.583.

    And TCP optimization is according to Z74. So i want this Z74 to be displayed in work coordinates (green).

    I think the issue is with the value putting to DRO from tool table. Optimization is correctly working.


    Waiting for your kind reply.

    Regards

    Amit Kumar

    Hi Amit,

    I believe that issue was discussed and solved here:
    https://www.cnczone.com/forums/dynom...ml#post2137030

    It should also be fixed in Version 4.34k. See Changes.

    Note that a bug was introduced in Version 4.34k where Screen Script Buttons that invoke Actions will fail. If you need that functionality you should apply this patch.

    HTH
    Regards

    Hello,

    Can I ask a bit of a basic question?

    I'm looking at building my second 5 axis CNC router. This time I want to have the RTCP path planning in my machine controller, rather than hard-code it into the gcode. I'm just starting to research Kflop and KMotion. Am I correct in saying that KMotionCNC can have its kinematics layer code modified by the user to achieve the desired kinematics to produce RTCP, as well as other path planning logic like limiting rotational motion to a certain angle? For example, a 5 axis machine that has RTCP and will also perform mid-operation C axis unwinds?

    Hi ChristianLL,

    Sorry I missed this but somehow it was posted with no subject title and so doesn't show on the forum.

    But yes KMotionCNC and our Libraries have a Kinematics Layer you can modify.

    Not sure what mid operation C axis unwinds are. But probably not. You can reset an angular axis to its 0-360 degree equivalent with an MCode.

    Regards
