Hello Alex,

Please attach the most recent version of your GH file, then I can take a closer look!

Thanks,
Johannes

Reversing the rotation axis of the turntable should flip the rotation direction as well - see the attached example!


Okay, so using Karl's x*-1 approach, I can now successfully reverse the turntable direction in my main Grasshopper definition, but this is still resulting in the same issue where I can see the A value increasing like before, rather than staying in a similar range.




Otherwise the approach would be to look into the machine data file, but let's keep that option for later.


I'm confused why this is the other option because the robot is doing what it is being told to do from the KRL, its more that the simulation isn't matching the KRL, if you understand what I mean?

Best,

Alex

Hello Gergo,

I didn't get any eMails from you, maybe the file size was too large?
And it definitely wouldn't hurt to have CIR movements for KUKA.CNC as well.

All the best tomorrow!

Dear Johannes,

Using circular movements was not on purpose: I just used the default settings of the fusion post-processor for KUKA|prc.
...and I found a solution for the moment: I set the minimum and maximum circular radius values to 0 in the post-processor.
The CIR-free XML code resulted in a valid NC generation in grasshopper. I will test the milling tomorrow.

At the same time, working on the implementation of CIR movements in KUKA.CNC sounds interesting since I'm working on architectural heritage projects milling/3D printing complex geometries based on laser scans. I sent you the files via eMail, please let me know if I can provide other data.

And thank you again for your help in locating the problem!

Cheers,
Gergő

Hello,

There was a bug that caused the code generation to fail, however there is a second issue as well:
We don't support CIR movements with KUKA.CNC yet. There is no special reason for that, we just never needed it and as a "Beta" implementation did not go further than what we needed for that project.
If you can provide some support (testing) and examples for CIR movements and KUKA.CNC I'd be happy to work with you to implement them.

In the meantime I would recommend not to use CIR movements with KUKA.CNC.

Best,
Johannes

Hello Gergo,

Now that is interesting, could you please send me the file via eMail? You mentioned Fusion - please also include the Fusion 360 XML file!

Thanks,
Johannes

Dear Johannes,

Thank you for your mail.
I updated KUKA|prc, but it didn't solve the problem.

I tried to play around with the toolpath by splitting it up, and it turned out, that the NC code can be generated up until line 1799, after which it stops operating. Up until line 1799, there are only LIN movements,  but Line 1800 would be a CIR command: could this be a cause?

Bests,

Gergő

Dear Gergo,

I'll send you an updated version via eMail to try out, just to see if it's your version of KUKA|prc or something else!

Best,
Johannes

Dear Johannes,

Thank you for your prompt reply.
I checked all kinds of options about the file generation (KRL/SUNRISE/CAMrob), which all generate files,
but KUKA.cnc option results in no file in the designated folder. I also checked the default location (desktop),
but there was neither any code generated there.

Could it be, that a certain component or setting is blocking the generation?

Support / Re: How to add two external axis
« Last post by Johannes @ Robots in Architecture on June 20, 2022, 11:46:06 AM »
Hello,

Thanks for the file. I see now that you cannot set the axis correctly with the default 1-axis positioner component, as it only provides a vector and always assumes the origin to be at zero.
Sorry for that. Can you specify in a bit more detail, what you want to achieve? Because the DKP 400 is included, and in the next release also another two-axis positioner. Are you using a custom system?

Two more general remarks:
Using the current date as the project name will not result in a valid SRC file. Start with a letter, don't use special characters and empty spaces.
Don't have GH automatically mesh BReps, that results in huge files. Mesh it in Rhino and then consider using ReduceMesh to get the size further down. This will greatly improve the KUKA|prc performance.
This applies even more to your tool - on my laptop, GH takes 10 (!) seconds to mesh it and creates a mesh with 1million faces - this will result in a super slow simulation. Try to get it to 5000 faces instead.

BEst,
Johannes
