If you have a task that is working well in Dex 3.6 and you would like it to work in Dex 3.5 you will need to do a few things to make this happen.
1. Open MATLAB, point the MATLAB path to the Dex 3.5 TDK
2. Open your task
3. Open Model Configuration Parameters
4. Set Solver -> Tasking Mode for periodic samples times: SingleTasking
5. Open Model Explorer
6. Set Model Workspace -> BKIN_STEP_TIME = 0.0005
For most people this will get you working. If you have made use of the From tags “robot1_motor_parameters” or “robot2_motor_parameters” then you will also need to use “selector” blocks to get the information out you need as opposed to a “Bus Selector”.
