Support / Re: "Spinning" Axis "Endlessly"

You could try to modify the code as follows to get a continuous motion:

FOR Counter=1 TO 20 STEP 1
   PTP_REL {A4 360} C_PTP
   CONTINUE
ENDFOR

However I cannot think of an easy way to get an axis to rotate with continuous speed "in the background" if that is what you are going for,

Hi Johannes, I started the file from scratch in the example I'm talking about.
Sure, we can look into it when you get back :) all the best!

Support / "Spinning" Axis "Endlessly"
« Last post by designfugitives on September 24, 2020, 02:00:28 AM »
I have axis4 type set to Endless.  Here's my quick code:

FOR Counter=1 TO 20 STEP 1
   PTP_REL {A4 360}
ENDFOR
FOR Counter=1 TO 20 STEP 1
   PTP_REL {A4 -360}
ENDFOR

This doesn't "spin" axis around around 360 degrees but rather like 5 and also there's a short pause between each of the FOR loop step.

What's the proper syntax for axis4to keep spinning endlessly in positive or negative?

Thanks.

Hello Nicholas,

If you opened an old file, try putting in the component again. Sometimes Grasshopper keeps the old labels, even if something new is now behind them.
Of course it might also be a bug, unfortunately I cannot check it myself until next week when I'm back in the office.

Best,
Johannes

Hi Johannes,

I am working on the Custom Turntable component (which seems to be updated from this example) for the user guide.
I am a bit confused with the base and table meshes where it seems to invert them. Is there a mixup in the inputs or am I doing something wrong?
Here is a video: https://youtu.be/03T-JB4rT2g

I thought about it a bit more, it's probably best if you just attach a screen to the DVI port and see if there is any error message on the Windows side.
While the smartPad is connected, you will only see the login screen, but you can login as kukauser with password 68kuka1secpw59 - note that if you do that with the smartPad connected, it will kick out the smartPad instead.

Best,

Hi Johannes,

As your code for the file access is probably generic Java, you could try running it on your PC and see if it also crashes there.
I've ran the file access part of the code in eclipse, and tested the chaging of the file content. Ran it for a few time, there was no crashes, everything runs fine.

Maybe you could log to a file, to understand where/when it crashes?
Sorry, but could you go into more details on how and what to log?

Regards,
Victor

Hello Victor,

If it kicks you out of the iiwa GUI to the screen in the screenshot, probably the entire Windows system crashed.
So unfortunately the SendKeepAliveMessage is most likely the result of the crash but not the cause. Maybe you could log to a file, to understand where/when it crashes?
Personally my guess is that there are some conflicting IO operations. As your code for the file access is probably generic Java, you could try running it on your PC and see if it also crashes there. That should make it more easy to troubleshoot.

Best,
Johannes

Support / IIWA SendKeepAliveMessage Failed
« Last post by victorlin on September 06, 2020, 05:09:43 AM »
Hi,

I'm running into a problem where the IIWA controller(?) would freeze and it'll display an message SendKeepAliveMessage Failed.
What I'm doing is using a modified read XML program, it runs in a loop, constantly checking D drive every half seconds for new files.
In D drive i have 2 files, one is simply a text file, if the content is 1, the robot reads and executes the second file then rewrites the first file to 0.
This program runs fine for short periods, but if left running for a while, the message SendKeepAliveMessage Failed will freeze the robot.
How can i fixed this?
(ideally I would be using the communicator solution, but for certain reasons, I'd prefer not to use it for now)

Attached is the program I'm running and the screenshot of the message

thanks,

Victor
