Hello Guys,

i am building the Stwart Platform.

When trying to conduct the demo, start movement i encounter strange jerk movements.

I uploaded a video of the behaviour; have a close look on MotorID4:

During the Motion it randomly jerks/jumps :(

Also if i use the processing interface and twice excecute the origin-command a actuators jerks out of origin position.
It is not 100% reproducably - thats why i twisted one of the D+/D- lines. (Thought it could be a EMF Issue, but it was not)
After twisting the lines the jerks keep occuring on the twisted pair.
 

I am using OpenCR with the newest Firmware.
Motor Baud: 1Mpbs; Protocol2;

I wrote about the same issue on Github which is probably the wrong place to discuss my problem.

Should i close this issue?

Thanks in advance;
Michael
