Hi RoboDK and other in the community.

I have a KR50, with KRC5 controller, and I was using RoboDK, version 5.2.5. I made a complete simulation of the cell and tested the program for reach limits and singularities. Then I went towards the offline programming, where I selected the postprocessor. There was no KR C5, which is also fairly new, so I selected the KR C4.

The result of the .src file and .dat file was however a bit different from what I normally would expect the outcome would look like. I transferred however the code to the robot, and it was working fine, but I was not able to e.g. touch-up the given robot position, because the code was in a different format.

One example is as below for a simple program, where the robot should move from home position to the position called StacksHome. The real code that will work on the robot is below, where it is possible to inline "touch-up" the e.g. StacksHome position.

The .src file is here and also attached as: KRL.txt

Code:

So the result from RoboDK will run on the robot, but I can not touch-up/reteach the position, i.e. online programming, using the teach-pendant.

So is there a way for, that RoboDK will produce two files, i.e. a .src file and a .dat file, which can be transferred directly over to the real robot, and then also be able for online programming editing afterwards?

Did you try the KUKA KRC4 DAT post processor?

Hi Jeremy.

Thanks for your reply. Ahh, I was a making a big mistake :) I was going to "Program" --> "Add/Edit postprocessor" and then beleved that I was actually using that given one. So thanks for linking the tutorial, that showed that I should right click on the given robot and then use "Select postprocessor". Make more sense :) Sorry for this.

However.... I then did the right way of select "KUKA KRC4 DAT", which successfully gave me 2 files, i.e. a .src and .dat file, which is shown in the attachment.

But:

In my program, I am first moving to two positions, which is defined in the base frame of the KR50 robot. Then I change frame to e.g. "Ceiling frame" and then move to two other position there, "Top" and "Top 2".

Then something is missing. Because the dat file shows that the BASE_NO is always reference to the same frame, i.e. the base frame.

As you can see in the code below, the dat file is only referring to P1,P2,P3,P4 where all these points are referring the BASE_NO 1.

And also, this makes me think about, that the names in the program tree is called "Home", "NewPos", "Top" and "Top 2". So there is something missing between the program tree and the final .src and .dat file.

One idea: Is it because I am not use Python here? I.e. should I make all this from the Python program, so that it can see the link from the program tree, i.e. "Home" to write exactly "Home" in the .dat file? :)

Two things,

You should add an ID at the end of your frame name: Ceiling Frame 2

Exporting the name of the target is not supported with this post processor.

I will try to add this feature in the next release of RoboDK.

Hi Jeremy.

Thanks for your reply. First of all, I wondered why I did not get a notification of your reply. :)

But what do you mean with adding a ID at the end of the frame :" Ceiling Frame 2" ?

[Jeremy]

Literally, just change the name of the frame in RDK so that it has a number at the end of it.
You might have to reselect the frame in the setref instruction (right-click->"set frame link")

Ok, I for it.

But why should I change the frame name to "Ceiling frame 2", when the robot program has no frame named "Ceiling frame 2"? See attachment...

[Jeremy]

The way the post-processor is built right now, it uses a "BASE" + "ID".
The robot base will be BASE 1 and is you add "2" after the frame name it will become "BASE 2"

Jeremy

[christian.hansen]

Just to catch up on this one.

Will this be added in the next release, and if yes, when will this be launched approximately?

Or was this already well functioning in the latest release?

Just wanted to clear up my understanding of your last comment.. :)

Ahh...

Now I think I got it :D

So this could actually work pretty fine, as long as I remember your comment about "name" + "ID".

Now also with screen dump of the .src file...

[Jeremy]

Yes, this feature existed for a few years now.
