Thank you for the prompt replies
Our electric team will check the cables, but we ran in to another problem
When we start the robot after booting, this screen pops and we can not press on any buttons, is like the screen freezes

We don't have a configuration CD, is all the krc data corrupted or we can skip this screen somehow?
Hello guys
We got a kuka krc1 from a company that don't use it anymore
Maybe is broken idk....
We are just trying to make it work for learning purposes
We have the following infos in the error list
Error writing digital output ports CAN : 2-3
Transmission error DSE - RDW1
Perform mastering A1-...-A6
Dynamic breaking active
Error digital imput reading CAN 1-...-4
Drives contractor OFF
General motion enable
Maybe you can give us a tip on where the problem might come from, for now we are just trying to move the robot to make some basic stuff, calibrate, make some simple trajectories and learn how some things work
Hello
I'm looking for a way to edit the coordonates and rotations of a point.

Hello,
We are trying to optimize a cell for cycle time and we have tried changing the process a few times and we are just a few seconds over 
The only solution left is making the welding sports from FINE to CNT.
What is the risk of this?
We are using 2 ARO welding guns mounted on robots and one ARO floor mounted gun all with PROMIA standard
We are using a powerfull spray arc and the speed is 72 cm/min
Can you tell me why the welding configuration is so important?
About the materials and workpiece , we have lap joints and v joints and the metal is at least 2mm in thickness.
Does anyone know how to approximate the distance until the robot starts to track?
We have some short welds , 30-50 mm , my question is how much the torch has to travel until the weld is applied where it needs to be.
We are currently using mechanical sensors that detects the overall geometry of the workpiece, but this method doesn't handle the multiple welding correction.
Mostly v groove but we have some lap joints too. The thickness is never less than 2mm.
When I say 0.5 I say the distance between the center of groove and the center of weld.
To be honnest 0.5 mm seems to me a low value, but this is the information I have from the plant.
I can go there and research more to be sure that they are not talking about 0.5 cm.
But even with that, what are the issues implementing weldguide on this type of application?
Hello,
I`m interested in a seam tracker that can help correcting a maximum 0.5mm deviation due to minor changes in workpiece geometry (the workpiece comes from 4 identical machines, that deliver slightly different results), on welds with length varying from 30mm to 200mm .
After a small theoretical study i saw that FANUC TAST could be a perfect solution for our applications.
On paper it seams (he he) a perfect solution, but i need a practical solution. Where can i find information about this sensor from a company that actually uses it?
Have a great day ! 
Is kind of both,
I almost graduated and i`m making the study at a big company.
We have issues with some workpieces that are not being welded propertly because of small differences in the geometry and the fact that same piece comes from multiple identical welding cells (that have different tolerances).
As you said in theory, WELDGUIDE seams (he he) like the Holly Grail but i wonder why i can`t find proper documentation on this.
I don`t expect someone to solve my problem, i`m just asking for guidance and where to find more unbiased info about this.
As i said we are a big company and we have contacts with ABB, but in our country there is only one company that uses this method.And the testimonials are only from ABB and they say it works wonders.
About the issues; i know it is restricting the torch mobility, we have errors under 0.5 mm, so it will be an almost unnoticeable weave so the torch won`t hit anything in this setup.
And for the distance to "home" how can i calculate, or approximate it ? from some videos i saw that in a V pattern (the configuration we need) i saw that [Home position = 3 x Initial displacement] so, by having a initial displacement of 0.5mm the robot will find home in 1.5 mm , which is not a problem on a 45mm weld
We are making 800+ heavy pieces per day and the process is optimized, the issue is that we have to retouch almost 200 pieces a day because of a small variation.
Edit: About the cycle time , if we increase weaving speed so in a manner that don't affect advance speed the cycle time will increase?
(except the minor triangulation in the beginning)
I mean, the welding speed will modify after adding the system?
Hello,
>I`m making a study about seam tracking
>I need a seam tracker for 30mm-200mm welds that doesn`t interferate with the cycle time and doesn't restrain the torch mobility
>SOOOO, Laser and Tactile sensors ------> OUT 
>After some reaserch i concluded that WELDGUIDE (or any tru-arc seam tracker) is the best 
>I mean, there wold be no reason to use something else ....
>I know is not like that, to finish the study i need some negative things about the ABB Weldguide
>Also, i need help with some aplications or compannies that already use WELDGUIDE (or some testemonials)
I wold be so happy if somoene could help me
