    MAHO 600E

    Hello, I`m a proud owner of a MAHO 600E with philips 432 cnc.
    I intend to upgrade it to MACH 3/4 using the indramat drivers (+/-10v), KFLOP+KANALOG and heidenheim linear scales.
    My first problem is the heidenheim scales, wich are Sin/cos type.... what comverter do you recomand to covert the to TTL or someting that will work with Kflop.

    Hi swat cat,

    Congratulations,

    Regarding scales I'm not familiar with anything in particular. I think you will need to determine if your scales output current (11uA?) or Voltage (1Vpp). I hear many find used ones on ebay such as these:

    Good luck

    Hello,

    Make your life easy and don't fix what is not broken. The original controller works just fine. The only issue on this machines is the fixed speed gearbox.

    Regards

    I have this problem. In some g code kflop is ignoring my mach3 motor tuning setings. It's trying to move with max acceleration

    i have this setings. On other g code file it`s working good with mach3 motor speed and acceleration

    Hi swat cat,

    It seems you are getting "zero radius arc" errors. I'm guessing you might need to change your Mach3 Configuration | Motion Mode | IJ | to incremental instead of absolute.

    In your Initialization C Program please set all of your MaxOutput settings to 2047 to avoid wrap around effects on Kanalog DACs.

    HTH

    I've modified to increment mode. It s not surpassing the error any more. But in the same zone i think it's pulling more acceleration than the config in mach3.

    Re: MAHO 600E

    Hi swat cat,

    I believe your C Program has Acceleration configured to be about 5 times what you configured in Mach3. This higher acceleration will be used for rapids.

    500000 counts/sec^2 / 1000 counts/mm = 500 mm/sec^2

    Does the problem occur on a Rapid?

    The video is not very helpful. Please run tests to determine what in GCode is causing the problem. Then post the GCode and your Mach3 XML file. What Version of KMotion and Mach3 are you using?

    Thaks for the reply. I tought speed and acceleration from step respose it s just for testing axis. An the Mach 3 motor tuning values matter in motin. Now it s working good after setting the good values.

    Re: MAHO 600E

    Hi swat cat,

    That's a good question and I don't have a clear answer. Mach3 normally creates the trajectory based its Acceleration. Unless the plugin is told to tell KFLOP to do something like a tool change, probe, home, etc. where KFLOP performs the motion itself.

    Re: MAHO 600E

    Can you post the G-code you're using?

    A couple things that stand out, is you go straight to a G3 from G0, and I'm wondering if Mach is then using rapids for the arcs. In which case from my understanding, Mach isn't controlling the motion profile, it's simply passing the required movement to the KFlop to handle at rapid speed.

    Also you don't need to continually define G17. G17-19 are Modal, which means once set, they stay set until changed. Most controls will default to G17 anyway, so you usually don't even have to define it.

    I don't have the. G code anymore.

    Some experiments.

    Re: MAHO 600E

    Tom, can you help me with a code for the main program for axis enable via binary input?

    When i power down Indramat i want k-flop to disable axis. Now when i power down and start it back up, all axis "jumps".


    And how can i fix Feed Over Ride in Mach 3 to respond instantaneously?

    Thx.

    Hi swat cat,

    When i power down Indramat i want k-flop to disable axis.
    How would KFLOP know you powered down the Indramat (I assume that is your analog amplifier) ?

    Now when i power down and start it back up, all axis "jumps".
    What do you mean by "Start it back up" ?

    And how can i fix Feed Over Ride in Mach 3 to respond instantaneously?
    There is no easy way to do this. You can reduce the delay by reducing the amount of buffering in our Plugin Configuration. Otherwise you would need to change the Mach3 Screen to add a Hardware Feed Rate Override and send the value to KFLOP.

    Re: MAHO 600E

    Hello. Indramat is the Servo Driver. I will use an Opto In from Kanalog board.
    If i power down servo driver, Kanalog will still try to compensate an error, and will start increasing Analog voltage until it will reach maximum value.When i power on servo drive,it will start to move cause of the voltage.

    I guest i need to link mach3 screen to hardware. Don`t you have a mach3 screen with all the fixes for the dellay?

    Re: MAHO 600E

    Hi swat cat,

    Yes if you interface the Drive Status back to Kanalog then you can monitor it and disable all of your KFLOP Axes. Then hopefully you can re-enable the servos in a graceful manner after power has been restored.

    You might start with the EStopDisablesAll.c example shown below.

    HTH
    Regards

    Code:
    #include "KMotionDef.h"
    
    // Watches for EStop Input and disables Axes when detected
    
    main()
    {
        for (;;)  //loop forever
        {
            WaitNextTimeSlice();
    
            // if ESTOP present disable any enabled Axis ??
    #define ESTOP_BIT 180
            if (ReadBit(ESTOP_BIT))
            {
                if (ch0->Enable) DisableAxis(0);  // axis still enabled?  - Disable it
                if (ch1->Enable) DisableAxis(1);  // axis still enabled?  - Disable it
                if (ch2->Enable) DisableAxis(2);  // axis still enabled?  - Disable it
            }
        }
    }

    I have some issues:
    1.i have home position set to 0,0. When i cycle start the g code te machine goes over the machine 0 point , in to hardware limits. After i hit stop and rewinde all is ok. Is going to machine 0.

    2. G code request a tool change but not updating actual tool.Must type manualy.

    3. Tool offset are weird. In the video, make tool change, cycle start. It takes a tool offset. But it s not the set one. I press stop and type again tool number the it takes the good tool offset.

    Re: MAHO 600E

    Have you looked at Centroid or DeltaTau for motion control? You're trying to mix hobby stuff with professional equipment. I don't think it will end well. At best you'll have a professional machine with a hobby shop control, and all the problems and shortfalls that come with it.
