UR and UR moveP post processors-GreenGuy-06-16-2021

Hi,

I have run into an issue when I generate a robot program. I am using the UR10 robot to move continuously through a set of points. To achieve the intended movement I am using Universal Robots moveP post-processor(RoboDK v5.2.4.), but for some unknown reason, blend radius parameter in moveP command is set to 0.000. This problem doesn't appear if I use an older UR moveP post processor which can be found here: (//www.sinclairbody.com/forum/Thread-Curve-Follow-Project-rename-allows-spaces-breaking-UR-script?highlight=processor).

Thank you,

This isn't really a bug.

We had some issues with the UR where if you use a blending greater than 40% of the distance between 2 points, it would create some very weird behavior.
So we added a filter.

As I can see the filter is more of a boolean gate, like blending or no blending.

The quick solution would be to reduce the blending value used in RDK.

Otherwise, I can see if we can improve the post-processor to use a bit more finesse in our filtering.

I looked at it and everything seems fine on my end.

Could you send me the .rdk station so that I look at your specific situation.

Hi,

Here is the .rdk station.

.rdk Test_PostPrecessor_MoveP.rdk(Size: 2.56 MB / Downloads: 276)

I understand that if I set the Rounding value too high it will be reduced to 40% of the distance between 2 points.

Here I set the Rounding value to 0.050, which is too high because the distance between 2 points is 45mm (I think). As a result, the value is reduced to 0.018.

But when I use the latest Post Processor instead of an older one, the Rounding value is always set to 0.000.

Hi,
Is there an update on the issue about the Rounding value?

I am also having this issue, is there a way to resolve it?


RE: UR and UR moveP post processors-Jeremy-04-08-2022

Hi Audrey,

Can you contact me via email?
I would like to run a few tests with you to see if this behavior is even required with the E series controller.

Hi,

I ended up updating my version of RoboDK and I stopped having that issue.
