... the stars needed? --> yes! [CmpCharDevice] PermittedPath.0=/dev/i2c* PermittedPath.1=/dev/spidev0.0 PermittedPath.2=/sys/class/gpio/* PermittedPath.3=/dev/gpiochip* For me it worked with this additional settings in the file /etc/codesyscontrol/CODESYSControl_User.cfg.

Hi darwin03, as can bee seen at the end of your video, the direction of rotation now seems correct for all axes. I can only guess, but the most likely reason are different denavit hartenberg parameters in the SoftMotion axis group editors and the robot used in the simulation tool. Maybe some arm lengths differ, maybe some offsets are given with opposite sign. I would again refer you to https://content.helpme-codesys.com/en/libs/SM3_Transformation/Current/SM3_Transformation/Function-Blocks/Standalone-Kinematics/Articulated-Robots/6AxisArticulated/Kin_ArticulatedRobot_6DOF.html....

Hi together, -> I updated my raspberry pi3 with runtime 4.22.0.0, and then no I2C device is running. -> when i switch back to runtime 4.20.0.0 all I2C devices running. what have i additionally to do, so that I2C Bus is although running in the newest Runtime Version 4.22.0.0 ? I did read something about security changes on the new runtime Version, but i do not clear understand, what i have do do, do bring the I2C Bus to live again ? ... there should be a Dialog in the Runtime Deploy tool, (see the...

Hi Georg, Thank you very much for your help and for taking the time to look into my issue! After reversing the directions of A2 and A3, the robot now moves correctly according to the coordinate system. That solved the main issue with the joint rotation directions. However, I still have two issues: When I command the robot to move along the X, Y, and Z axes, the movement seems slightly off, and the trajectory appears somewhat diagonal instead of following a straight line along the commanded axis....

Hi darwin01, looking at the video and comparing the movement with the first figure in https://content.helpme-codesys.com/en/libs/SM3_Transformation/Current/SM3_Transformation/Function-Blocks/Standalone-Kinematics/Articulated-Robots/6AxisArticulated/Kin_ArticulatedRobot_6DOF.html, I think that the direction of rotation does not match between the RoboDK model and the CODESYS 6DOF kinematics. In the CODESYS kinematics, A1 and A2, when moved in positive direction, rotate into the opposite direction to...

I have encountered an issue with Alarm management. A simple Alarm table to display active alarms. Historical alarms can be hidden and can also be cleared. Overall a history of 10000 alarms before it cycles. On one instance this error displayed: "Some kind of disk I/O error ocurred. Check disk space". Picture attached. I have seen this with an online change, but it was resolved by a full download. But this case was running for weeks and displaying alarms fine. The logged errors though were unusual....
