Dear Johannes
I have found 1 reason that makes my stepper motor get vibration cause from I to use multiprocess in python to make stream E1 and run the stepper motor simultaneously. Because I think stepper motor not run done of drive command but get new command to start at beginning of stepper motor drive command all the time. So, I have tried to use join() in multiprocess this makes the program must run the process of the stepper motor done then this makes my program can stream E1 again but this makes the program stop because stream E1 value in real-time if have stop command it will stop stream E1 value and make the program stop. Have any suggestions for make steam E1 and run the stepper motor simultaneously?
Best regards,
Settawat
