Hello Charles,

Great! Keep me updated, via forum or eMail!

All the best,

Support / Re: kuka|prc compatible with krc1?
« on: November 22, 2017, 04:40:04 PM »
Hello,

If your robot is doing an ellipse instead of a circle (and a curve instead of a line when you move it manually in XYZ), most likely an axis is not properly calibrated.
So you will need to calibrate it again. Do you know how to do it, do you have the tools?
There is the proper way with an EMD, and there is the DIY way that basically just requires some stick and sensible hands ;)

Best,
Johannes

Hello Christian,

A common issue is that libraries sometimes may get blocked when they are downloaded from the web.
You could try to go to %AppData%\Dynamo\Dynamo Revit\1.3\packages\KUKAprcDynamo\bin and right-click each of the DLL files. Choose Properties and then if there is a button called "Unblock" click it and confirm with OK. I would see this as a likely reason for the total disappearance of KUKA|prc after you copied the extra libraries that it were missing before.

If that does not help, please get in touch via johannes@robotsinarchitecture.org so that we can troubleshoot in a more focused way.

Hello,

Great, thank you for the update! Also don't put any empty spaces within the filename, or numbers to the front.
The option in the settings should solve the issue with BAS!

Hello,

Is the USB-floppy converter working with other *.src files?
If the hardware is not at fault, you might just need to enable the "Improved Compatibility with older KRC2" option in the KUKA|prc settings.
And if that does not help, select your file and it should show you an error list, with the line of code that is causing the issue - that should narrow it down!

Best,
Johannes

Hello,

I quickly added a few components how that might be approached, see the attached file.
If you want to automate it more nicely, you can use Weaverbird to create the Dodecahedron, then you get the outlines and use Boundary Surface to create a planar surface. If you "untrim" the surface, you get a square patch. Then after reparametrizing it, you can automatically generate your cutting line as a isocurve through 0.5/0.5, and get the orientation by evaluating the surface at a random point (as it's planar, it does not make a difference where, you can simply use the default 0,0)
I did not know Fibro, they look very heavy duty! As you cannot do synchronized movements with it (unless you replace your motor with a KUKA motor, that is) you then need to figure out the rotation point in relation to the robot.

The easiest way to do that, is to calibrate a tool and set the base to 0 (world coordinate system). Now move to a point on the turntable and note the cartesian position. Move the table by at least 100 degrees and repeat at the same position. Repeat again. With three points, you can then construct a circle in Rhino/Grasshopper. The center of the circle will be the center of rotation.

Hope that helps!
Best,
Johannes

Hello Christian,

Hmm.. That is interesting. It seems that there is a problem with the System.IO library. I've uploaded it here:
https://1drv.ms/u/s!AtgYyPhhrKrMnKouasc3qSMPGyO2NA
As you are running Dynamo for Revit, please copy/paste the following line into the address bar of the Windows explorer (not internet explorer, the file manager)
Code: [Select]
%AppData%\Dynamo\Dynamo Revit\1.3\packages\KUKAprcDynamo\binAnd then put the two *.dlls from the ZIP file there.

On my Windows 10 it's running fine, but maybe Windows 7 needs some extra support.
Please let me know if that worked!

Best,
Johannes

Hello,

I'm currently travelling so I cannot look at your file, but if the fabrication time is not critical you could simply work with a very generous retraction strategy, so that even if the face you cut is opposite of the robot, it will still not collide with the foam block. Ideally go up in vertical Z in addition to retracting.
With the visualization in KUKA|prc it should be easy to check. Usually there should not be an necessity to tell the turntable to "wait" - or did you build it yourself, without a KUKA motor inside?

« on: November 16, 2017, 09:27:17 AM »
Hello,

IOs start with a state of OFF, so an additional OFF will not register.
You can override this behaviour by using a Custom-KRL component instead with e.g.
$OUT[1]=TRUE

Hello Robert,

Architecture is such a wide field - if you want to do customized fabrication, complex geometries etc. using a robot could be very beneficial and helpful, but in many other areas you are not involved with fabrication.
So it really depends what kind of products or services your company will offer!

Hello Nickolas,

The collision checking will be much improved in the next member release, probably this weekend, with much less memory consumption.
For other purposes, the PRC calculations are quite fast, but it takes a while for Rhino to display all the lines etc. So a good start is disabling the display of frames, and in general hiding geometry in Grasshopper. That will greatly improve the viewport performance.
There is a dedicated slider for that in the menu - but you can also do it manually.

Regarding your replacement system, I don't believe that Rhino benefits greatly from Quadro cards, so you could easily go for a GeForce as well (unless you are using other software that does).
But I'm assuming that the X5670 system is refurbished or used? I guess for ~250EUR or so for the entire system it would have a good price/performance ratio, but as a 7 year old CPU basically any quad core you can buy today will be faster. The cheapest Ryzen quad core with HT (~4+4 cores) is 150EUR, a B350 mainboard 60EUR, and 16GB RAM 130EUR - the graphic card you could easily buy used.
KUKA|prc uses multithreading for some operations, while Grasshopper itself not so much - that seems to be coming with Rhino 6.

If the bottleneck is the HD4000, you could also buy or borrow a graphics card and see if it makes a difference. Literally any card should be faster than the Intel.

Hope that helps!
Best,
Johannes

But after you have reinstalled everything, you can simply activate your project thorough WorkVisual and everything should be back in place!
You will lose all projects that you saved on the controller between the time you created the project and now, but the controller shouldn't be used as a program archiv due to memory limitations anyway.

That is definitely not supposed to happen. With the Cross3 error and the "online services" I would guess that the problem is somehow related with the real-time part of the KUKA. You didn't change any network settings, did you? Otherwise I would really recommend calling KUKA, see https://www.kuka.com/de-de/services/technische-hotline-und-beratung
Have your robot serial number ready!

Hello Otto,

Most likely it's sufficient if you just upload your WorkVisual project again, providing you've still got it somewhere. Or you can try activating a previous project at the controller. Projects can be accessed via the blue-ish button with a robot and a gear on the left side of the smartPad - you need an elevated user group.
That being said it's a good idea to make backups, you can either use the special KUKA backup USB stick, or just create an image of the HDD with an external program.

As your profiles says that you're based in Germany: KUKA offers a very helpful technical hotline that does not charge anything during business hours here, which is probably the fastest way to get help!

Best,
Johannes
