Its not clear how that should work.  Maybe use the Rapid Speed Override Slider/setting to also change the Jog Rate?  But that could be confusing for the Operator.  We're open for suggestions.

I suppose if we added the capability for KFLOP to read the Rapid Rate Override then each User would have the power to handle it however they wish.

Or better yet, can the feedrate be used for continues jog buttons some how?

SetJogOverrideFromKMotionCNC-14707(1).c
GetJogOverrideFromKMotionCNC-14707(1).c

Hi Troy,

I suppose that is possible using KFLOP's capability to set a Jog Speed Override.  See the attached examples that Get/Set the Jog Speed Override.

Combining that with code to read an Edit Control on a custom Screen should work.  See the Add.c example that reads two Edit Controls from the Screen.

Does that make sense and seem reasonable?

Regards

TK

 

Hay Tom,
 Can the Slow Percent box on the Tool Setup>Trajectory Planner tab be added to the Custom screen by using the Screen Editor?

Thanks,
Troy

ScreenValueToJogSpeed.c-14717.txt
DualPane3AxisSplitJogRate.scr-14717.txt

Hi Troy,

No worries.  I'm trying to understand and find the most general approach.

Regarding ips vs ipm.  That's just to be confusing :)  The idea is to have all the parameters in consistent units of Time - seconds.   Jerk, Acceleration, and Velocity.  I think it is more common to use seconds when calculating trajectories and such.  But I realize Machinists like to use minutes as rates were typically very slow.  But the Machinists and Operators will never see those parameters anyway.

Because adding a Jog Rate the way I described is easy and doesn't require any KMotionCNC code changes I went ahead and did it.  Maybe you could try it out and see what you think.  I've attached a screen script and the associated C program.

Here is a Video describing how it works:

Hi Tom,

"You should be able to add a Slow Jog Percentage the way I described
earlier. "
Using another DRO for jogging feedrate works ok for me. Will have to see if i can figure out as much as i can before i start bugging you on how to add it. ;)

" For example if the Jog Speed for an axis was configured for 5ips
and the operator enters 2ips (or 120ipm) then KFLOP could set the Jog
Speed Override to 0.4"

This brings up something that is a bit confusing to me. Why is it ips instead of standard ipm?
And why is the Feed and Rapid override DROs in KCNC a decimal format instead of percentage?

"I would think some Operators would find it annoying or confusing to have
the system Jog at the last entered feedrate or feedrate of the Job they
ran some time ago."

I kinda see how it might affect other users. But anyone who is used to industrial CNC controls, will operate jogging in the manner iam describing. Using current feedrate and FRO for continuous manual jogging.
Some controls use a percentage of currently selected incremental move similar to how KMotionCNC does it.

" Also not all Axes in the system may be possible to
Jog at that rate."

Wouldn't the axis just move at its maximum?
How does it work now?

Hope i dont sound like iam picking. :)

Thanks,
Troy

Hi Troy,

Sorry to hear about your Drive.  But I always say if you don't blow something up once in a while then you aren't trying hard enough.

That function GetEditControlDouble should be included in the latest V4.34i KflopToKMotionCNCFunctions.c

Are you referencing an older Version?

Regards

TK

KMotionCNCSimple3AxisStepDirV6-14725.c

Hi Troy,

That brings to light some issues we hadn't considered.  The update takes about 0.5 seconds because it involves 5 commands to KMotionCNC and KMotionCNC only polls for a command ~ 10 times per second.  So dropping that in your loop which previously looped about 5000 times per second doesn't work (switch debounce time becomes huge).

Give us some time to figure out a solution.

Regards

TK

 

Ok. New jog DRO works but none of my physical input button/switches work now. Does there need to be a different kind of wait loop in C program for switches and Jog DRO to work?

Troy

Hi Troy,

No this is something we'd like to work well.

Here is a patch that adds a mechanism that informs KFLOP whenever something is typed/changed in an edit control.  Every change increments a count (EditChangeCount) and the count is sent to KFLOP with every status update.  That way KFLOP can update the Jog Speeds only when the Operator changes something on the screen rather than all the time.

The patch involves:

 - A new KMotionCNC.exe

- New KFLOP Firmware that needs to be copied to the DSP_KFLOP directory and Flashed

- The example ScreenValueToJogSpeed.c changed  (please merge the modified UpdateJogSpeeds function into your Init C Program)

Here is the patch

http://dynomotion.com/Software/Patch/AddEditControlsChangeCountToKMotionCNC_V434i/

 

Ok. Hope i didnt open a can of worms for you. ;) No hurries. Wish i knew more so i could help out.
Thanks again,
Troy

KMotionCNCSimple3AxisStepDirV6-14751(1).c

Hi Troy,

Oops.  Forgot to include the new KMotionDef.h which defines the EditChangeCount as an external integer.

It is now added with the patch files. Copy it over the old file in the DSP_KFLOP directory.

You should remove the 5ms delay in the loop.  Leave only the WaitNextTimeSlice() so the loop runs at your original rate (~every 180us)

 

Hi Tom,
 Iam trying to compile my main INIT C program at my desktop PC and i get a error stating: C:\KMotion434i\C Programs\SimpleHome.c:38: 'EditChangeCount' undeclared
Attached is my C program.

Troy

Hi Troy,

Strange the new KMotionDef.h should have that defined in it.  Did you overwrite the original in the DSP_KFLOP directory?  If you open it in an editor does it contain:

extern int volatile EditChangeCount; 

void EditChangeCount; probably wont work.  You would need to add the line above to it references the external variable rather than creating something new and of the wrong type.

Thanks

TK

 

Ok. After i added the new KMotionDef.h i got this error: tcc: undefined symbol 'EditChangeCount'

So i added to beginning of my C program: void EditChangeCount;
Is this correct? As i dont get any compile errors now.

Thanks,
Troy

Hi Troy,

Strange.  No it shouldn't matter where the C Program resides.

Try deleting or renaming the KMotionDef.h file and verify you get a file not found message to verify it is really using that file in that location.

The Compiler will search several locations for #include files but it should start with the DSP_KFLOP directory.

What is the exact directory path+name of the KMotionDef.h and the path of the KMotion.exe file?

Regards

TK

 

Yes i replaced the original KMotionDef.h in DSP_KFLOP directory. I checked and the line:
extern int volatile EditChangeCount;
is in file.
Does it matter that all my C programs that iam using are in there own folder within the C Programs directory?
Troy

Hi Troy,

I was miss-reading the error message.  Actually the error message:

tcc: undefined symbol 'EditChangeCount'

Indicates that it was defined in the .h file and compiled correctly but when trying to link to the KFLOP Firmware DSPKFLOP.out file the firmware doesn't have that symbol defined.

Did you download and overwrite the patched file DSPKFLOP.out to the DSP_KFLOP directory keeping the same name?

Regards

TK

 

Forget to post error when deleting the KMotionDef.h.
C:\KMotion434i\C Programs\SimpleStepDir3AxisMill\KMotionCNCSimple3AxisStepDirV6.c:1: include file 'KMotionDef.h' not found

Hi Troy,

I found another mistake.  Please re-download KMotionCNC.exe from the Patch

Thanks

TK

 

Dont know why but i copied and replaced the DSPKFLOP.out file again and now it compiles correctly. So i then tried it on my mill pc and compiled correctly. But after i replaced my KMotionCNC.exe i get the following erroe window when trying to launch KMotionCNC on both PCs:

KMotionCNC MFC Application
KMotionCNC Application has stopped working.

and another a Windows window with details :

Hi Troy,

Thanks again for your patience and persistence with this.

We want that to work also.  But isn't it working as before?  There should be Slow and Fast Jog speeds which are selected either with the Keyboard arrow and shift.  Or by clicking the Slow or fast screen buttons with the mouse.  Slow is the configured percentage in Tool Setup of the fast (ie 25%).  My example set the Fast speed to move at the entered Feedrate on the screen.  So to move at the entered Feedrate you would need to click the Fast button or do Shift-Arrow.  So then the Operator has the option of the Specified Feedrate or Slower.  It sounds like you would prefer setting the Feedrate as the Slow rate which would then allow Shift-Arrow to be Faster.

Is that how it is working for you?

Regards

TK

 

Hi Tom,
 One thing that might be added to this function. Before when the Shift was held down during a Keyboard jog axis would travel at fast feedrate or rapid feed rate. But, to me its not really needed, now that its easy to adjust feed on Main screen. Only a thought.

Thanks again,
Troy

KMotionCNCSimple3AxisStepDirV6-14771(1).c

if (GetEditControlDouble(&rate, 170, 1000)) return;  // exit if value is invalid

To

if (GetEditControlDouble(&rate, 170, 1000)) return;  // exit if value is invalid
rate = rate * 2.0;  // double the entered rate so slow (50%) Jogs at the entered rate

Regards

 

Hi Tom,
 What should i change in C program? I tried changing this:
if (rate < 0.0) rate=0.0;
if (rate > 1.0) rate=1.0;

to this:

if (rate < 0.0) rate=0.0;
if (rate > 1.0) rate=2.0;

But nothing changed in KMotionCNC. I also tried C Program without the above lines and it made no difference in KMotionCNC. Attached is my C program.
