Hello,

I would need to know which university so that I can check if the license is still valid. You can also send me an eMail if you do not want to share the information in a public forum!

Best,
Johannes

Thanks for the reply.

I am using a member license through university.

Hello,

Thanks for getting in touch!
Can you provide some more information on your license - are you using a member license, e.g. through your university, or were you using a Community Version?

Thanks,
Johannes

Support / License Error with Kuka PRC for Grasshopper

Dear all, I usually use KUKA|PRC for Grasshopper. But today, I had issues with license error when connecting robot to Core.

It used to work normally. What is the cause?

Hello Gergely,

Hmm, so you have got your Cartesian World and Cartesian Base coordinate system.
My guess is that there was a mismatch somewhere, so you either moved the robot in Cartesian World but displayed Cartesian Base or the other way around.
Is that possible?
It usually shows the Cartesian position of the currently activated base (see towards the top of the smartPad, next to the tool number) and on the right there is the World movement (globe icon) and the Base movement (plane icon) type.

Best,
Johannes

General Discussion / Strange base coordinate movement results
« Last post by gergole on September 17, 2022, 05:30:08 PM »
Hi there!

We have noticed a weird thing with our KR10.
We calibrated a tool and a base, then used a base movement offset 10m in the z axis to check the base geometry.
However, even if we only used x and y movements, the z value also changed when checking the display/actual position in the cartesian coordinate system, even at points, where we executed the base calibration. Any thoughts?

Hello Luigi,

I just checked your file, it did not contain a single movement command, which confuses KUKA|prc.
I will make sure that this will result in a proper error message in the next release.
For now, just add an axis movement somewhere and it should be fine!

Best,
Johannes

Hello Luigi,

Can you please send me the file that is causing the exception via eMail?
Take electronics advice from me with care, but Beckhoff IO units have got many different configurations, I don't know if yours have got a separate ground port. But if you are e.g. switching an electronic gripper, then I would personally try to either power them from the same power supply or alternatively connect the grounds. But again, don't trust me with electronics ;)

Best,
Johannes

Hello Johannes!

Looks like we have the beckoff installed and wired to the X12 connector.

Also, it seems like everything is mapped correctly as we were able to make a manual KRL file that turns on and off the digital output 1.


However we get this error in KUKA//PRC most likely i am doing something wrong.
1. Solution exception:Object reference not set to an instance of an object.

Finally, when connecting to an external output is there a ground in the beckoff?
