  1. Re: Tool length Offset activated as part of Initialization file

    Hi Dan,

    If offsets are screwing up when finding tool height then I would think you would want to clear them when finding tool height not only when homing.

    You could clear the Global Offset by...
  2. Re: MAHO 1000 c hardware with Kanalog KFlop controller advice

    USDigital is a good source. You will need to select what will work for you mechanically. Most any digital incremental encoder should work. Choose a differential output as that can work with either...

    Re: C code for button

    Hi Joe,

    To move to GCode Coordinates rather than Machine Coordinate zero you might use GCode instead of C Code. Create a GCode file (MoveToZero.ngc) something like this:

    G0Z-0.75
    G0X0Y0
    M30...

    Re: Lagun FTV3

    Hi Jeepguy,

    single ended encoders should not be connected to Kanalog.


    It probably won't work reliably. To be within specification the + and - inputs must have > 0.2V differential positive...

    Re: Lagun FTV3

    Hi Jeepguy,

    A differential encoder must be connected to Kanalog's differential encoder inputs. See our FAQs here and here.

    You can purchase 3rd party cables/modules to convert single ended...
  6. Re: Mach 3 does not recognize home position.

    Hi Peter,

    Please try setting the M3, M4, M5, and S Actions to Exec/Wait.

    Please zip your C:\CNCLathe directory and post it for us.


    Can you repeat this and describe more precisely what you...
  7. Re: Taig CNC-Controller Replacement-Dynomotion Suggestion

    Hi Peter,

    Kanalog is required to connect to KFLOP's JP7 connector. Adding a Kanalog will require you to remove KStep from JP7 and you will lose the extra KStep IO (16 opto inputs, 2 opto outputs,...
  8. Re: Mach 3 does not recognize home position.

    Hi Scott,

    great. Next check if KMotionCNC | Tool Setup | M3 M4 M5 S Actions are configured to use the Correct Jog Programs. Post a screen shot.

    What happens when you enter M3 S500 in...
  9. Re: Mach 3 does not recognize home position.

    Hi Scott,

    ok great, DAC commands are working. Next try Jog commands. I believe your Spindle Axis is #4? If so then try Jog4=10000. Of course the Axis needs to be configured and enabled by...
  10. Re: Mach 3 does not recognize home position.

    Hi Scott,

    No. You should be able to just use the Screen Set I posted here previously.


    Probably both. Those should be two separate and independent problems.

    I'd work on getting KMotionCNC...
  11. Re: Taig CNC-Controller Replacement-Dynomotion Suggestion

    Hi Peter,

    OMG 8 relay driver boards for $12 with free shipping. How do they do this?

    I think your connections would likely work and could not possibly cause any damage.

    But technically it...
  12. Re: Taig CNC-Controller Replacement-Dynomotion Suggestion

    Hi Peter,

    Higher resolution is always better until you exceed the count rate of the encoder input at maximum RPM. KFLOP can conservatively accept 1 million quadrature counts/second.

  13. Re: Taig CNC-Controller Replacement-Dynomotion Suggestion

    Hi Peter,

    Wow 300mm 5um resolution linear scale for $50 + shipping? I couldn't find the pinout but it says TTL/EIA422 (differential) so it should work.


    Yes it is compatible. Purchase the...
  14. Re: Mach 3 does not recognize home position.

    Hi Scott,

    Not sure what you mean by this. What file? I already made a screen set with the code in place for the Home All Button, All you should need to do is save the file I posted. Remove the...
  15. Re: Taig CNC-Controller Replacement-Dynomotion Suggestion

    Hi Peter,

    On the bench steppers can run really fast. You really need to have them connected to the machine to see what they can actually do loaded then back down to provide a good margin. Here...
  16. Re: Mach 3 does not recognize home position.

    Hi Scott,

    Strangely it seems the standard Lathe 1024.lset screens don't have anything assigned to the HomeX, HomeY, or HomeAll buttons. Switching to the standard 1024.set screens for a mill and...
  17. Re: PID Servo Tuning with SnapAmp Chicken and Egg Variables

    Yes 4th power with radius and 1st power with length. Much of my experience has been with laser scanning mirrors that have very high accelerations. People often suggest increasing motor size to draw...
  18. Re: Taig CNC-Controller Replacement-Dynomotion Suggestion

    Hi Peter,

    There isn't any tuning involved with steppers they are open loop. It is really just a matter of finding your limitations on velocity, acceleration, and Jerk. You might read this. I...
  19. Re: PID Servo Tuning with SnapAmp Chicken and Egg Variables

    Your hired:). Yes 5th power of size. Mass is 3rd order with size. Then each particle of mass further out needs more torque to get the same force and also needs to accelerate to a higher speed.
  20. Re: PID Servo Tuning with SnapAmp Chicken and Egg Variables

    Hi Jason,

    No, I think that is reasonable.

    btw I think the moment of inertia increases with the square of the gear ratio.

    Which reminds me of my favorite job interview question: How many...
  21. Re: PID Servo Tuning with SnapAmp Chicken and Egg Variables

    Hi Jason,

    Is the encoder on the lead screw or the motor?

    Higher resolution and more torque to the lead screw would be good.

    But how lower gearing will effect the control loop is hard to say...
  22. Re: MAHO 1000 c hardware with Kanalog KFlop controller advice

    KFLOP/Kanalog conservatively accept up to 1 million quadrature counts/second. So for example if the max RPM of the encoder is 3000RPM then the maximum encoder resolution will be:

    1e6 / (3000/60)...

    Hi Mark,

    Re: Lagun FTV3

    Hi JeepGuy,

    Yes, much of KFLOP (DSP, Boot FLASH, SDRAM, FPGA Configuration) must work for that to occur. But that doesn't mean those might not be partially damaged in some manner.

    Re: Lagun FTV3

    Hi JeepGuy,

    Only one blink of the LEDs indicates it thinks there isn't any USB connection. You might try a different USB cable, or USB port, or PC.

    The encoders do need to be common GND to...
