It's a stepper machine, without position feedback, controlled by parralel port. When pressing stop while the tool is moving, it goes to a new position in appearance in a controlled way, at the same speed it was moving before pressing stop. I tested several time, the position it goes seem to be the same at each try, but I can't let it go where it want because the trajectory of the tool at that moment results in a tool break. So I must stop it with Estop before the end of the move, so I can't be really sure the final position is always the same, and I'm not sure if it is a position corresponding to some point in the program or not. But seems to go to the final position it shoul reach at the end of the program. I should test again for this, but the machine is in production now. ------------------------------------------------------------------------------ Magic Quadrant for Content-Aware Data Loss Prevention Research study explores the data loss prevention market.
