    Default Automatic Tool Height Sensor input to KFLOP

    Hi everyone,

    I am looking to install a Auto Tool height sensor or Z zero sensor and then add tool height to tool table.

    I have a Z plate to do that. I have to touch the tool with that Z plate and set the height in tool table accordingly.

    same as seen in auto tool height setter in youtube.

    So which program do i have to run for doing so.

    And Please help me in wiring same to kflop

    Waiting for your Reply

    Thank You

    Hi Amit,

    Its up to you to interface your probe to KFLOP. Are you trying to just check continuity from the tool to the touch plate? Is the tool isolated? Do you have any opto isolated inputs available?

    Once Interfaced you might start with the ProbeZ.c example:
    Code:
    #include "KMotionDef.h"
    
    main()
    {
        Jog(2,-100);                       // move Z down slowly
        while (!ReadBit(1040)) ;           // wait for switch to go high
        Jog(2,0);                          // Stop
    }
    Regards

    Are you trying to just check continuity from the tool to the touch plate?
    Yes i want to check continuity and enter the automatic tool height in Z direction.

    No i don't have isolated input. I just want to calculate tool height using Z touch plate.

    waiting for your kind reply.

    Hi Amit,

    Its recommended to use an isolated input. Jeremy in the video apparently used an opto isolated KStep Input Bit number 171. If you don't use an isolated input you will be wiring a part of your machine directly to a KFLOP input. Any noise, static electricity, ground noise can cause KFLOP to malfunction or be damaged. Do you understand the danger in doing this?

    Regards

    Hi tom

    Thanks for your reply.

    there is one more addition in my problem, the tool height setter i am using is of laser and its automatic.

    So according to that which io and c program i should use with laser or non contact tool setter.4

    Waiting for your kind reply

    Hi Amit,

    You would need to tell us more about your tool setter. Only saying it is non-contact and has a laser is not sufficient for us to be able to help you.

    #1 what is it?

    #2 how does it work?

    #3 what kind of output does it have?

    #4 is it isolated from ground?

    Regards

    Hi Tom,

    Thanks for your reply

    NC4 non-contact tool setter here is the link for NC4 non-contact tool setter.

    Now please look into that and let me know.

    Waiting for your kind reply.

    Amit, what interface are you using with the NC4?

    Renishaw probes/sensors don't provide a digital output (and having checked the datasheet for the NC4, the sensor provides 2 analogue outputs), and rely on a dedicated interface to provide outputs suitable for controllers.

    Hi Tom,

    Thanks for you reply.

    I am using a touch plate for measuring tool height.

    I have a Metal push button which is mounted at a fixed height from the spindle. When tool presses the push button kflop is getting the signal either high or low.

    But now i want to measure the tool height from the same metal push button as all heights are known reference height from spindle non rotating part to button, and tool tip to button.

    So what should i add into my probe.c program to perform the following operation.

    I also want that measured tool height from push button to write into tool table for respective tool number.

    How to do that also?

    Waiting for your kind reply.


    Thank you

    Regards

    Hi Amit,

    It seems you forgot to post your probe.c program.

    Please look at the ToolTableSet.c example.

    Please read this Thread:

    mmurray70's method may work for you.

    Regards
