    Here is my answer to your question and your machine....

    Hello Robert,

    here you can download the used config:
    https://github.com/aschiffler/linuxc.../machine_cloud
    Perhaps it is difficult to understand. (perhaps erase all commented
    lines for a clear view)

    Here are some preconditions:
    - The drive for the A-Axis / Lathe-Main-Spindle can be switched from
    position control to speed control mode and vise versa
    - In my setup all drives have a digital field bus (ethercat); the
    communication is done via the module "lcec"; lcec.0.6 is the
    lathe-axis-drive.
    - To switch the Operation Mode lathe/A-Axis you "online" you have to
    unhome/home the a-Axis. (Therfore i have added some buttons in pyvcp,
    see vcp.xml)

    Hope that gives some hints to help you.

    The config 'machine_cloud' has add. data logger functionality; see video
    linuxcnc2cloud on my youtube channel for background.

    Regards
    Andreas
    Andreas thanks for the information. I am also currently working on a hardware/software solution that would have the spindle as default but switch to A-Axis when selected.

    I should be posting new pictures and video soon.

    Thanks

    I have been working on a design based on the iBOB2 and Gizmosphere 1. The Dimensions of the GQ1 are Width 6.79", Height 6.61" and Depth 10.29". It has 6 axis of +- 10V analog servo control and all I/O are available on 2 DB50 and 1 DB 25 connector. The RJ45 is for a pendant interface. It could also be made for step and direction. I prefer true closed loop control. I plan on selling the iBOB2 for anyone who wishes to make a ultra small CNC controller or place the complete controller within a small case or enclosure. The small circuit board in the back left is the iBOB2.

    Where did you get this control panel from?

    He built it. As in the pictures right above the one you linked.

    Thanks but I am not that dense that, I can't see or read the posts. That was not what I was asking about, I want to know about the control panel he has mounted in his enclosure. I fixed my post so the picture shows up.

    Dan I found it new, on ebay a few years ago. I am currently connecting the functions to a Mesa 7i77 card.
    The MPG and E stop were added later, also found new on ebay.

    Thanks,

    I have had to repair the encoder, it was faulty / defective. I have posted all the information that I could locate that might identify the encoder.
    It appears to be a 755A with a 10mm shaft with flat. In the Novaturn, only A and index are used.
    I modified my encoder to provide all signals, A A', B B', Z Z' which will be used for position control.
    I had to replace the ET7272B as it was faulty. I may modify the case to accept a 10 pin connector for quick disconnect.
    For those of you who might have a damaged or faulty encoder, please see the information below.
    I am currently designing a circuit to interface the Hardinge control panel to the MESA 7i77. This circuit will control the leds and membrane switches without using any additional I/O on the 7i77.
    Has anyone else looked at the Gizmosphere for CNC / control applications?

    I hope this helps,

    Default PathPilot on AMD Gizmosphere1, T40E + iBOB2

    I am almost finished. I have PathPilot running on the GizmoSphere 1.
    Specs:
    G-T40E dual-core processor running at 1.0 GHz, combined on a single die with AMD Radeon™ HD 6250 discrete-class graphics. The board provides a performance capacity of 52 gigaFLOPS (GFLOPS) at less than 10 watts. Custom high- and low-speed edge connectors enable a full range of functions. This unprecedented level of integration between serial and parallel processing offers a power-efficient foundation for high-performance multimedia content delivery across a broad range of embedded designs such as digital signage, x86 set-top box (xSTB), IP-TV, thin client, information kiosk, point-of-sale, casino gaming, media servers and industrial control systems.

    Currently decoding I/O on the Hardinge interface. The MPG, Axis select, and Rapid Override are functioning under Linuxcnc. I just need to change the bit file and 7i77 I/O for complete functioning.

    The Denford NovaTurn uses Inductive Sensors, BES 517-352-NO-L. I currently have them functioning in PathPilot. X and Z reference works correctly and also sets the soft limits.
    Will post video soon and use PathPilot to make initial test parts.
