now i`m working for the external control . FRO SSO and Rapid OVR

i need to start the .c program manualy ( it`s running on thread 6). i don`t know why it`s doing that....

This is annoying.... why

Hi swatcat,

Did you Flash the correct program into Thread #6?

Actually we don't recommend Flashing anything into KFLOP for exactly this reason. It becomes confusing to remember all the things that were done to KFLOP and what its current state is. Its simpler to keep KFLOP in a Virgin state and have the PC load what is needed as it is needed. KFLOP can be restored to its virgin state by re-Flashing using the "New Version" button.

Its also preferred to use less Threads by combining all the things that must be serviced continuously into one forever loop in your Initialization Program that runs in Thread #1. Its often good to run things in separate Threads for debugging but once working they can be combined into one Thread. It looks like you have 5 Threads running? Are you able to do this? You might read this.

You might also cleanup and indent your programs properly to make them easier to read and understand. A context menu option was added in V4.34a to do this automatically. See here.

Now i'm running all the threads for testing reasons. In the final version i will merge all of them in one file.

Yes. The program it's compiled and downloaded to thread 6.

I've imported open c Program (thread 6) and flashed it again.

Now it's working.THX

Hi ALL

I would like to get schema how to make cable for connect with PC 9 PIN with TRAUB TND 200. I saw some one have a SERVICE book in english.I is possible to share the schema page ?
Many Thanks in advance.

I have some problems with G95 feed per revolution

FRO it`s not changing the feed value

When i change SSO, Kmotion freezes or give a error.

What i am doing wrong?

and Feed Hold not working, Program HALT stopping after Look Ahead time (2s)

[TomKerekes]

Hi swat cat,

What Version of KMotion are you using?

Feed hold stops in the worst case stopping time for all the axes in the Coordinated Motion System. A common problem is to have a KFLOP Axis configured in an odd manner (high velocity and low acceleration or Jerk).

Please post your C Programs and how KMotionCNC Tool Setup is configured.

[swat cat]

4.34, i've been waiting for the official version of 4.35.

In normal motion g0 ,g1 feed hold and motion halt works instatenous.


Tool setup is the same as in post #17

this 4 are running until i make a version of them in one file

[swat cat]

I've installed version 3.35b. The same problem.

It's not ok.

Hi swat cat,

Thanks for upgrading to V 4.35b

Regarding FRO, Feedhold, and Halt: KMotionCNC ignores those in G32 and G95 modes. The assumption is that the feedrate is synchronized to the Spindle and doing something like cutting a Thread so Halting or changing the Feedrate would result in a damaged part. I suppose it might make sense to support this in some cases as an option.

Regarding SSO: I haven't been able to duplicate the problem but I don't have all your hardware and such. I modified the "Pot" program to just vary SSO as a slow sine wave and it seems to work ok. Its hard to follow your Video exactly what you are doing without a description. I suspect the problem is related to the use of multiple Threads. The functions to send commands to KMotionCNC are not "Thread safe". That is if multiple Threads try to send commands to KMotionCNC at the same time bad things can happen. The functions assume KMotionCNC is ready to receive a command and sends it. Then waits for it to complete before returning and potentially issuing the next command. If before the command is completed another Thread goes ahead and issues a command things can get confused and overwritten. Please merge the programs together that send KMotionCNC commands so only one command to KMotionCNC happens at a time and see if the SSO Pot then works correctly.

On a side note I see some minor issues in the code:

This code:

	double Pot1, Pot2, Pot3, FRO, SSO, RAPIDO, T;
	BOOL PotSetFeedhold = FALSE;
	printf("FRO start\n", FRO);

passes FRO to printf without a defined value ever being set. Also the FRO shouldn't be passed if it is not used by a %f in the print string.



Similarly this code checks FRO before it is set to a valid value

		if (FRO > 2.0)
			FRO = 2.0;			// limit FRO to 2.0 max

This code in the case that Pot1 is exactly 0.4 leaves FRO unset. You might use greater than '>' and less than or equal '<=' instead.

		else if (Pot1 > 0.2 && Pot1 < 0.4)
			FRO = 0.05;
		else if (Pot1 > 0.4 && Pot1 < 0.6)
			FRO = 0.1;

Thanks for the answer. G95 generaly it is used turn a part with constant chip thickness.( could be used for threading but you have g32). https://www.cnc.com/what-is-a-g95-gcode/

So g95 it's a great mode to turn a part... and for that FRO it is needed. (I gues SSO works).

Regarding the feed hold and motion stop, it's very important not to crash a tool or something worse..soo if in G32 or G95 mode i hit feed hold.....this means something is wrong and by doing that i prefer to scrap the part rather to damage a tool or spindle.


So, pls think of a solution for those issues.This two options are very important for a lathe.

I'm pretty sure every CNC controller will have in G95 mode the FRO active.
https://www.haascnc.com/service/code...value=G95.html
"G95 Feed per Revolution (Group 05)

When G95 is active, a spindle revolution will result in a travel distance specified by the Feed value. If Setting 9 is set to INCH, then the feed value F will be taken as inches/rev (set to MM, then the feed will be taken as mm/rev). Feed Override and Spindle Override will affect the behavior of the machine while G95 is active. When a Spindle Override is selected, any change in the spindle speed will result in a corresponding change in feed in order to keep the chip load uniform. However, if a Feed Override is selected, then any change in the Feed Override will only affect the feed rate and not the spindle.
"

And the same with feed hold command...

I need a solution.. withoud feed hold it's a very dangerous situation and without FRO it's useless G95

Thx

Her is a patch for V4.35b that should allow FRO and Feedhold with spindle sync active.

Copy these to C:\KMotion435b\DSP_KFLOP folder
DSPKFLOP.out
DSPKFLOP.sym
KMotionDef.h

Copy this to C:\KMotion435b\KMotion\Release folder
KMotionCNC.exe

Please let us know of any issues.

[swat cat]

Hello. I need to turn on some light indicator when the machine is Running a gcode ,
Feed hold; what variables should i check to Setbit()?

[TomKerekes]

You can test JOB_ACTIVE for when GCode is active.
Test CS0_StoppingState > 0 for Feedhold
