Hi!
I have a strange phenomenon that when I use only one motor, there is no mistake, but when I add the second motor, the following problems will appear. And it should not be the problem of yaml file. I can run it when I test it alone. Don't you know if you can help me?

but I have installed maxon_epos_driver according to your suggestion? Could you share the maxon_epos_driver?

Hi I had run example_maxon_epos.launch in branch mulitiple_motors and it shows "motors initialized", so what can I do next to move the motors, I had tried running sample.cpp and sample.py but nothing happened...
Thanks for your help!

Dear all,
I use ROS1 Noetic with Ubunto 20.04.6 LTS.
I have downloaded and installed the latest Maxon Library from "https://www.maxongroup.com/maxon/view/product/control/Positionierung/546714".
It is Version 6.8.1.0, not Version 6.7.1.0, as suggested by @Roboprotos in Jan 2022.

I git clone maxon_epos_ros.
Then I do this fix: "<build_depend>maxon_epos_driver</build_depend>
that line should be added in the package.xml file inside the maxon_epos_example package"

When I then run catkin_make, it throws this error:

[ 97%] Built target maxon_epos_example_node
/usr/bin/ld: /home/ahkub/Desktop/WorkHere/catkin_ws/devel/lib/libmaxon_epos_driver.so: undefined reference to VCS_OpenSubDevice'** /usr/bin/ld: /home/ahkub/Desktop/WorkHere/catkin_ws/devel/lib/libmaxon_epos_driver.so: undefined reference to **VCS_CloseSubDevice'

Can somebody please help?
Or maybe somebody knows where I can still download EPOS-Linux-Library-En.zip in the old Version 6.7.1.0?

Much appreciated!

I have catkin_make successfully, but when I connected to Maxon motor and EPOS4, and run roslaunch maxon_epos_example example_maxon_epos.launch, it occur an error.
