most likely this is a tuning issue within the Rutex drive. If I understand correctly you are driving the rutex with step/dir signals from the parallell port. EMC will have no idea of where your machine is, it relies on the drive to close the loop. So, your following error setting should be in the rutex drive. If the following error limit is set too high the behavior you describe would be allowed. Try reducing the allowed following error in the rutex drive and then maybe re-tuning it.
