Im doing some testing with a UR5, and i am having a pop-up show at the start of the program asking the operator to input a number anywhere from 1 - 6. when the operator selects 1 or 2, that will instruct the robot to move to pick up either a green (1) or red (2) marker then im using switch cases to step through the rest of the program. After it picks up the marker, i have a variable called "TOOL_SELECT" and which ever marker is selected is the value. However whenever i stop and then restart the program, the value goes back to 0 then when i call the switch case to return whichever marker, it moves back to the home position instead of returning the marker. ( i have it returning home if the TOOL_SELECT variable had a 0) is there a way to keep the current marker selected? or is it always going to return to 0 after a stop?
