This is the first time i've heard of this problem, and it's not at all what i would expect. When emc2 is restarted, it reloads the hostmot2 firmware into the Mesa board and clears all the encoders, so any movements that happened before that time are completely lost. After that it tracks position, and shouldnt get confused by e-stop or anything else. Can you provide any more details? -- Sebastian Kuzminsky ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
