  1. Re: Limit rotary axis motion to +/-180 degrees

    Hi Zach,

    This is very insightful thanks. I had dreamed up such a mechanism, but dismissed it as being overfussy. It's reassuring to know it is used for industrial applications. Do you know of such...
  2. Re: Limit rotary axis motion to +/-180 degrees

    Thanks for your reply. I'm using KFlop, which indeed is highly configurable. FOr SW I'm using my own application - but lets say Mach3 or KmotionCNC since I can apply the same principles in my...
  3. This is brilliant, thanks very much Tom....

    This is brilliant, thanks very much Tom.
    Confirmed it's working fine for me.

    Great to have Kmotion and KmotionCNC working too!
    I hope that it's possible to continue to distribute 64-bit version...
  4. Limit rotary axis motion to +/-180 degrees

    Hi, I need some advice about designing max limits for a rotary turntable.


    The axis is a stepper motor driven rotary stage.
    The turntable can rotate continuously, but for my application, I need...
  5. Re: 64 bit version of KMotion libraries for MATLAB and other 64 bit platforms

    Sure, here you go. I'm using the KMotion_dotNet.dll in the release directory....
  6. Re: Announcing Kogna 16-axes Ethernet Motion Controller

    Looks fantastic. Having some onboard analog I/O will be really useful. I look forward to trying it soon.
  7. Re: 64 bit version of KMotion libraries for MATLAB and other 64 bit platforms

    Adding the location of KMotionServer to the Windows PATH environmental variable sorts that out, thanks!
  8. Re: 64 bit version of KMotion libraries for MATLAB and other 64 bit platforms

    That did the trick thanks, the example works. It also seems to be working fine with MATLAB now - I've made a quick video showing it running.

  9. Re: 64 bit version of KMotion libraries for MATLAB and other 64 bit platforms

    Thanks Tom. Since my last post I've continued chipping away at this. I see Kmotion, KMotionCNC applications in this release are 32 bit. That's fine, I only need the libraries.


    The 64 bit...
  10. Re: 64 bit version of KMotion libraries for MATLAB and other 64 bit platforms

    Hi Tom,

    That is extremely helpful thanks! I've just dowloaded it and see that KMotion excecutable doesn't run (missing GCodeInterpreter.dll). Looks like some of the libraries are not built.
    Do I...
  11. 64 bit version of KMotion libraries for MATLAB and other 64 bit platforms

    Hi All,

    I'm attempting to use the wonderful Kflop from MATLAB, a popular numeric computing platform. My initial plan is to use the KMotion_dotNet dll since MATLAB has a .NET interface.

    Re: Is KFLOP right for my application

    I've received my KFlop+Snapamp+Kanalog. Many thanks.

    Should the motor power supplies for the SnapAmp be regulated or unregulated DC?

    Thanks.

    Re: Is KFLOP right for my application

    Excellent. I think I'm ready to order KFLOP+SnapAmp +Kanalog (for some AD/DAs).

    Silly question - can you confirm if the ADCs and DACs on the Kanalog are DC coupled, i.e. can output and read DC...

    Re: Is KFLOP right for my application

    Great, thanks TomKerekes.
    I took the cover off our encoder and found a TTL line driver IC,

    Also after some more searching through the our U500 controller manual, found: Encoder feedback channels...

    Re: Is KFLOP right for my application

    Hi TomKerekes,

    Thanks for your previous reply. On encoders, I've noticed that KFLOP only supports encoders with digital outputs. I can't find a part number for the encoders on out motors but it...

    Re: Is KFLOP right for my application

    Hi TomKerekes,
    Thanks for the reply.
    I'm an idiot, I totally meant that we were considering SnapAmp for this application (was reading up on KSTEP for a personal 3D printer project) Very good to...

    Is KFLOP right for my application

    We're using a laser vibrometer to perform vibration scans on various objects.
    The system consists of an Aerotech U500 motion controller (PCI), and a pair of Aerotec 1000DC servo motors, one of...
  19. Re: Advice and recommendations for replacing an ageing controller

    Ah, that looks like it could be perfect. Thank-you for the suggestion ger21. I see there is even a sub-forum for KFLOP controller here on cnczone. Always a plus to have a decent community of users.

  21. Re: Help needed for small mill to cut molds for an injection molding machine

    Fascinating thanks probinson. The stratasys example is shows some potential, although I'm still confused by how a mold can hold it's form when injected (with moderate pressure) by melted plastic...

    Tkamsker, what a great little machine, that could be perfect. I'll look at it in more detail. Thanks!

  24. Re: Help needed for small mill to cut molds for an injection molding machine

    speedtwin69, thanks, yes I've been quite tempted by the chinese 6040 machines on ebay (accepting they need the stepper wires chaanged and control unit upgraded). You can buy just the machine body...

    I've been trawling though the threads here, but it seems that my requirements might not fit the typical cnczone metal machine purpouses, so I'd appreciate some guidance.

    Basically I...
