Thanks for reply, I have configured my salve robot to the external positioner ,but I think there is a problem in my cell configuration in compare that with picture that you have post it .you can take a look to my attachments files .
It seems I have to defined a base between my salve robot and my external axis . (my external axis is connected to the master robot)
At the moment I am using KUKA robotTeam 3.1 and ArcTechBasic and ArcTechAdvanced .
one question regarding the motionsynch over Spline as blew !!!
When I use Spline block with Sync instruction during the welding process ,
Should I add sync instruction for each point that are included inside Spline block or not ?
to better understanding if I define a SYNC with synchronization flag to the header of Spline block is enough ?
Note: I try to use ARC SPLINE also that is included inside of ArcTechAdvanced,
one thing is amazing I can not add any motion inside of ARC SPLINE . I don't know why KUKA is provided this instruction !!!!
