You could slow everything down by changing the slider speed in a script.
socket_open("127.0.0.1",30002)
socket_send_line("set speed 0.10")
socket_close()
For 10% you set the speed to 0.10, when you want to speed up you simply run the script again with the speed set to 1.0.
I am running a small program where I need the robot to change speed rather drastically. I have found that using a stopl(1.0) for example lets the robot decelerate and stop before moving on. Everything I have found says that after a stopl() or stopj() the robot will continue on with the program but for some reason my program stops and never continues. anyone have any suggestions? It would be greatly appreciated.
