I have a Meca 500 that I have successfully run programs with moveJ but moveL commands send the robot to do movements that are not shown in simulation. The program then errors out due to the handshake failing as the theoretical position does not match the robots true position. To illustrate I have two photos. The first shows the simulation after I ran a moveL in run online, then after I updated position of the true position of the robot and the pose changes. I have tried a variety of programs and different methods of using moveL. The Hexagon program attached is a basic one off git that leads to a failure.

I've attached my station. The 'Hexagon Test' and 'Linear Move' programs both work in simulation but not in online as discussed.

Can you try with the API mecademicpy driver?
Do you set robot.setPoseTool() and robot.setPoseFrame() in your program?

Hello Sam,
When I try to use the apimecademicpy.py driver I receive this error message.

I am not connected to internet when I connect to the robot in this case, but I am connected to the robot via wifi.


Currently I am not usingrobot.setPoseTool() or robot.setPoseFrame() in my programs.

Try adding robot.setPoseTool(robot.PoseTool()) and robot.setPoseFrame(robot.PoseFrame()) in your code.

This crash log is because you are missing a dependency (mecademicpy).
What is the driver version you are using (see the log)? You need either mecademicpy 1.2.1 or 1.3.0 depending on the driver version.
The driver that is shipped with the latest version of RoboDK requires mecademicpy 1.3.0.

[Jeremy.West]

Yup the robot.setPoseTool(robot.PoseTool()) did the trick; linear moves now run as expected.

From my log I have
