  1. Re: Milltronics Partner 1 Kogna Conversion: Build thread

    Hi Nate,

    ok. Note: rapids are performed with 3rd order limited Jerk, so can be quite smooth even with higher velocities and accelerations. So if you re-visit this try lower values of Jerk.
  2. Re: Milltronics Partner 1 Kogna Conversion: Build thread

    Hi Nate,

    Looking good.

    I see about 1700 DAC counts are required to do 300ipm. So 400ipm would be 1700 * 400/300 = 2267 is more than the DAC range of 2047. So I think you will need to change...
  3. Re: Milltronics Partner 1 Kogna Conversion: Build thread

    Hi Nate,

    You are correct there is a bug where the Kogna DAC is not being zeroed on disable. We will fix this in the next release. A work around would be to add:


    KOGNA_DAC(0, 0);
    ...
  4. Re: Milltronics Partner 1 Kogna Conversion: Build thread

    Hi Nate,

    This shows the commanded DAC voltage. It should be exactly 0 if the axis is disabled. If the offset pot has been adjusted for no motion when DAC 0 is commanded I don't understand why it...
  5. Re: Milltronics Partner 1 Kogna Conversion: Build thread

    Hi Nate,

    Sorry I somehow missed your earlier posts.

    Usually you should set the Gain Pot such that at 10V the system moves at a bit higher velocity than you will ever use. This allows use of...

    Re: If (Check) {Do Something}... ?

    Hi Jeff,

    A general way to handle multiple events using a single Thread is to use a State Machine, See the untested example below:


    #include "KMotionDef.h"

    // Press Brake control

    enum {...

    Hi Jeff,

    Is that a typo? Can you explain more clearly?
  8. Re: Press Brake with Linear Encoders with a Reference Mark: How to wire to Kanalog Bo

    Hi Jeff,

    Encoder Ref Marks are handled in KFLOP/Kogna Software so can be connected to any available input. Differential signals can be connected to any unused A or B differential encoder input. ...

    Re: My Fadal 4020 Kflop Retrofit

    It's hard to say if the 160V is needed, Do you have the motor spec? If not you might run a test. The speed of a DC motor is basically proportional to Voltage under light load. So you might apply...
  10. Re: Milltronics Partner 1 Kogna Conversion: Build thread

    Well we did say "basically" :)
  11. Re: Milltronics Partner 1 Kogna Conversion: Build thread

    You might read this. The Driver's + and - outputs basically switch from less than 0.4V to greater than 2.8V relative to its ground in a complementary manner. The receiver checks which signal is...
  12. Re: Milltronics Partner 1 Kogna Conversion: Build thread

    Hi Nate,

    Encoding should work fine just change the MPG C Program to look for the codes instead of individual bits. However I don't think it is wired correctly. Kogna/KFLOP JP7 inputs are logic...
  13. Re: Considering Milltronics control retrofit: questions

    Hi Nate,

    Thanks for your insight. You have logical thinking and good communication skills so I have no doubt you will succeed. I think you lose nothing by utilizing the existing drives. Worst...

    Consider a Dynomotion KFLOP / Kogna Controller with Free KMotionCNC GUI and Kinematics :)

  15. Re: Considering Milltronics control retrofit: questions

    Hi Nate,

    Yes Kogna is software and hardware compatible with KFLOP. The same C Programs for KFLOP will run without changes in Kogna.
  16. Re: Considering Milltronics control retrofit: questions

    Hi Nate,

    That could be correct. It depends on whether the number 1024 refers to quadrature transitions or quadrature cycles. When you say counts I think of transition counts. Normally cycles...
  17. Re: Considering Milltronics control retrofit: questions

    Hi Nate,

    The simulated resolvers should work but hard to say what the accuracy would be. Assuming the lead screw directly connected to the motor and 1024 counts per rev that would be 0.0002"...
  18. Re: Upgrading KFLOP 4.33 on old win XP Computer to New Computer Win 10 and Kflop 5.3.

    Correct
  19. Re: Upgrading KFLOP 4.33 on old win XP Computer to New Computer Win 10 and Kflop 5.3.

    Hi Eric,

    Keep a backup.

    If you copy the contents of the previous Data folder to the new Data folder any new files should not be affecteded.
  20. Re: Preventing G-code execution in C, and problems evaluating while loop conditionals

    Hi Andy,

    That should now be Threadsafe.

    Thanks for posting the code.
  21. Re: Preventing G-code execution in C, and problems evaluating while loop conditionals

    Hi Andy,

    I don't understand. Are you still executing code without the changes I requested? Please attach the files you are using.


    Unless there is a WaitNextTimeSlice() in the loop then the...
  22. Re: Preventing G-code execution in C, and problems evaluating while loop conditionals

    Hi Andy,

    You might remove all Axes from the Coordinated Motion System with:

    DefineCoordSystem6(-1,-1,-1,-1,-1,-1);


    I can't explain this, but one possibility is there is noise on the...
  23. Re: 64 bit version of KMotion libraries for MATLAB and other 64 bit platforms

    Hi George,

    Thanks for the time for posting back.

    Yes all future Versions will include both 32 and 64-bit Versions.
  24. Re: 64 bit version of KMotion libraries for MATLAB and other 64 bit platforms

    Note the 32/64-bit code has been released. See the 5.3.0 announcement here.

    Hi Troy!

    Thanks much for sharing.
  26. Re: 64 bit version of KMotion libraries for MATLAB and other 64 bit platforms

    Hi,

    You should just be able to unzip KMotion5.2.1x64 and use it like any other installation and it has the x64 libraries pre-built in the \KMotion\Release64 folder.

    KMotion.exe is only a 32...

    Re: Upgrade issue

    Hi Ted,

    After this you should get a Disconnect message. Click OK. Then Flash New Version. Then re-boot KFLOP and restart KMotion.

    Re: Logitech F710 Game Controller Issue

    Hi Ted,

    I think there are some settings in Windows for reducing drift with gamepads/joysticks.

    But yes an MPG such as that directly connected to KFLOP would be much better and have guaranteed...

    Re: Problem with Encoder output on DMM drives?

    Hi Mark,

    I would expect something like that if the scope was not grounded. Obviously the measurement is incorrect as 100V would have already damaged Kanalog.

    It looks to be around 20KHz which...

    Re: How do I override the limit switches?

    Hi Lotrek,

    It would be better to eliminate the noise.

    But to disable limits see my previous post.
