I’ve never been able to get repetier to “unpause” a paused job made from estlcam. I just make it two different jobs with the exact same start point. Then I just write down my x/y offset from x/y home to set the job zero. You can set the z zero by eye, or use a touch off plate. Sometimes, depending on the job, by eye doesn’t always work, since you may have cut the zero position.
