Hello,

Can you please send me your $config.dat, then I can test it on my system!

Thanks!

Support / Kuka PRC Crash
« Last post by donjorges on November 06, 2019, 05:31:04 AM »
Evening all,
I just upgraded the 3rd version of PRC, and when I load the $config of the robot (it asks me twice, i select it twice) it crashes.

I'm on a Kuka150/2, KS version4.97, on windows 7, and rhino5.5.

any sugestions on the issue?

Thank you very much for your detailed explanation, I learned a lot from it. The problem may be Sorting and joining of curves. Because I successfully drew another simple figure(few letters) before. And I will try again according to your advice .

Thank you again for your prompt reply and detailed explanation.

Best,
Wang Cong

Hello,

There are a few things to consider, first of all the hardware. If you are not getting straight lines, then either your tool is wobbly or your mastering is wrong.
On the software side, the C_DIS settings are crucial. You can set the $apo.cdis variable either from Display/Variable/Single (in Expert user group) or in the KUKA|prc settings.
It blends movement, the unit is mm. So if blending is enabled for a movement (default in KUKA|prc, you can change it by right-clicking the icon of e.g. a LIN movement) it will smooth movements. For drawing that means that the pen doesn't lift of vertically, but when it's x mm (the value of $apo.cdis) away from the lift-off, it will blend the movement and move diagonally up. Then again if you have $apo.cdis set to 0, or disabled the C_DIS option for a movement, the robot will stop at every position, which also isn't ideal.
For proper drawing you can try to disable C_DIS for the first and last position, and set $apo.cdis to a value that allows you to get sufficient accuracy, while also ensuring a smooth movement of the robot.
Sorting and joining of curves is something you need to implement in Grasshopper, KUKA|prc will not reorder your toolpaths by itself, as that could cause serious issues.

General Discussion / Drawing Tool path is not smooth
« Last post by Wang Cong on November 01, 2019, 09:55:14 AM »
Hello,

I have some questions about the drawing, when I put the SRC files into the robot, the logic of robot drew the picture was unordered, it didn't draw smoothly and fluently. There were a lot of movement, especially a lot of point.  So it doesn't look very good. You can see it in the image below.

So I would like to konw that how can I make it go in one derection or more logically? or can I control the order of drawing?

Well, you need to keep in mind that if you change the base, the simulation will no longer be valid.
So it might work, but it may also cause collisions and problems.

Hello,

That's great, I'm glad that it was easy to resolve!!

All the best with the iiwa,

Hello Johannes,

After listening to your advice, I compared the files of KUKA|prc with the computer which can work well. I found something different and reinstalled KUKA|prc. Now, It woks very well. Many Many Thanks !
I notice the KUKA|prc(V3) is improving forward. And I'm just beginning to learn iiwa. So I am very expect for it and I hope everything goes well!

Best,
Wang Cong

Can you inadvertently cause issues if you change the base, Johannes?

Hello,

The .NET framework is only the most likely problem. Sometimes people don't use the installer, but just copy the files, omitting the two OxyPlot DLLs.
Is it possible that happened? The two files should be in the same folder as KUKA|prc.

Best,
Johannes
