General Discussion / Re: KUKA|prc User Interface Er...
Last post by utsoa - April 22, 2025, 06:51:55 PMUpdate> I've uninstalled all plugins and Rhino. Cleaned any remnants of Rhino and Grasshopper libraries, then reboot. Reinstalled Rhino and started Grasshopper. All is good. Next copied the "KUKAprcGH" with the list of files into the Grasshopper\Libraries\" folder and started Rhino then Grasshopper. KUKA|prc exists in Grasshopper as expected. When using PRC_SimplePath.3dm" and "PRC_SimplePath.gh" to test, choosing KUKA|prc Settings shows the same User Interface Error. Next I've removed the "KUKAprcGH"folder and installed only the KUKA|prc through the package manager. Restarted. Using PRC_SimplePath.3dm" and "PRC_SimplePath.gh" to test, choosing KUKA|prc Settings shows the same User Interface Error. I haven't found a combination that'll work.
I was able to install the KUKA|prc plugin on a test system which has never seen Rhino/KUKA|prc successfully and the KUKA|prc Settings works.

Last post by utsoa - April 22, 2025, 06:12:08 PMConfirmed. The list of files below do exist in the "Grasshopper\Libraries\KUKAprcGH" folder. I did fine a few remnant files in the "Grasshopper\Libraries" folder which I have moved out. (KUKAprcCore.dll, OxyPlot.dll
, OxyPlot.Wpf.dll). Unsure of why those ended up there but are now moved. I uninstalled any/all plugins from the package manager in Rhino. Only the KUKA|prc remains and runs in Grasshopper. Using "PRC_SimplePath.3dm" and "PRC_SimplePath.gh" to test. When choosing the "KUKA|prc Settings" shows the same error. Next step for me is to uninstall all KUKA|prc and Rhino related items and start again. I have been able to get this setup running on another few systems, just not my main.
KUKAprcCore.dll
KUKAprcGH.gha
KUKAprcLibrary.dll
KUKAprcLibraryWIN.dll
KUKAprcLicense.json
Newtonsoft.Json.dll
OxyPlot.dll
OxyPlot.Wpf.dll
OxyPlot.Wpf.Shared.dll
System.Drawing.Common.dll

General Discussion / Re: KUKA|prc User Interface Er...
Last post by Johannes @ Robots in Architecture - April 22, 2025, 05:14:30 PMSorry to hear that it is still causing issues!
I wrote the text below and will leave it for troubleshooting. In your case however, I'm pretty sure that the problem is that you have got KUKA|prc installed twice. You have to install it EITHER via the PackageManager or the Component Library. As you have got access to the member version which is updated more frequently, I would recommend removing it from the PackageManager.
//////////////////////
Here are the troubleshooting steps in more detail:
1) Make sure Rhino is closed.
2) In the Grasshopper Component Library, temporarily move all files and folders except for the KUKAprcGH folder into another folder
3) Go into KUKAprcGH and check if it contains the following files:
KUKAprcCore.dll
KUKAprcGH.gha
KUKAprcLibrary.dll
KUKAprcLibraryWIN.dll
KUKAprcLicense.json
Newtonsoft.Json.dll
OxyPlot.dll
OxyPlot.Wpf.dll
OxyPlot.Wpf.Shared.dll
System.Drawing.Common.dll
System.ValueTuple.dll
4) Start Rhino again, check if the settings work now.
5) If not, run the "PackageManager" command. Temporarily remove any installed plugins
6) Restart Rhino
7) Test again
If any of the tests is successful, you can start re-adding components to see which component collides with KUKA|prc.

Last post by utsoa - April 22, 2025, 05:00:21 PMHi. Thanks for the reply. I've confirmed all components exist in the "C:\Users\%user%\AppData\Roaming\Grasshopper\Libraries\KUKAprcGH" directory. KUKA|prc v1.0.8810.26816 is installed and listed when looking at the PackageManager in Rhino8. So, presumably, all parts and components to run the KUKA|prc plugin are where they need to be. Loading a .3dm file with a .gh script shows the model and script as expected. When choosing the "KUKA|prc Settings" button within Grasshopper, I receive my initial Interface Error. Not sure where to go from here to troubleshoot. Thanks for working through this.

Last post by Johannes @ Robots in Architecture - April 15, 2025, 04:59:09 PMHello,
I found it in the error list but it does not provide any information on how the remedy it.
It is listed as error 1053 "CP-Vel. reduction point <point name> <dummy> by <reduction in %>"
I would just contact the KUKA hotline as it seems like a straightforward question. Maybe it is related to the linear axis, because we did plenty of projects with C_VEL and I never (knowingly) got that message...

Johannes

I'm getting the error KSS01053, but unfortunately I haven't been able to find any explanation or details about it.
Do you know what might be causing this or where I could find more information?
Thanks a lot in advance!

That does not primarily sound like a pathplanning-related issue but more related to the robot setup.
I also wasn't able to find an error message saying "speed reduction at point..." - does it have an error number? Alternatively it might be something that was specifically implemented for your robot. Like a short code in your sps.sub comparing programmed speed to actual speed.
It is common that the robot slows down when it is close to singularities etc., but it usually will not create a specific error message for that.

General Discussion / Speed Reduction
Last post by FM - April 13, 2025, 07:17:33 PMHi,
I am programming a KUKA robot using the Grasshopper tool for concrete printing. The printing trajectory is pre-defined, and I intend to execute specific segments of the print using an inclined nozzle configuration. The robot operates on a linear unit, and I have already incorporated modifications in the print code to ensure that the straightening process is executed at a slower pace. However, during the transition from the inclined configuration back to the upright position, the robot's control system enforces a deceleration, with the SmartPad displaying an error message stating 'Speed reduction at point xxx.' This behavior suggests that internal safety protocols—potentially related to kinematic limits, proximity to singular configurations, or abrupt changes in motion dynamics—are triggering the enforced speed reduction. I need to determine the exact cause of this deceleration and identify strategies to mitigate it.
Thanks for your help.

Thanks a lot for the update, that is valuable information. Very weird why the referencing worked on my end but needed intervention on yours, but the result counts :)

Last post by mehradmahnia - April 06, 2025, 08:10:03 AMThe problem solved;
I've moved the KUKA|prc library to GH's Library folder and removed the folders in Rhinov8 and Rhinov7's package manger folder, and seems that it fixed the problem.
