Hello, i am Working with one External Axis to Move the Robot at it self on the X-Axis. I configured the External Axis with the External Axis Wizard - AddIn. I have 3 WorkObjects (Red arrows) and one teached in Position (green arrow). ![|774x556.png](https://europe1.discourse-cdn.com/flex005/uploads/robotics1/original/2X/6/6372909fef2d4c199543bf6d44a757804310b83e.png) The Problem is, when telling the Robot to move to the green “teached-in” Position: MoveJ LKAblageFKT,v100,z50,LkGreifer\WObj:=FKT3; The Robot is not driving to the teached-in Position. Atleast i have to set the external Axis value to Zero to reach the right position. When I randomly Change the Value of the external Axis (form 0 to 300) the actuall Robot Position in Robot Studio starts moving away… The Robot Position on FlexPedant stays the same ?!? (see Table below) ![image.png](https://europe1.discourse-cdn.com/flex005/uploads/robotics1/original/2X/d/d279ef7cf6109718b134d0e24b3a0a7c41533145.png) In the System-Konfiguration both (External and Rob) Base-Coordinatesystems match ? ![|970x398.png](https://europe1.discourse-cdn.com/flex005/uploads/robotics1/original/1X/a0808d8ab3c158cb7b2723da60b844e366d8e8bc.png) Hopefully somebody can help me with this issue 🙂 Many Thanks in advance !!!
