An undesirable effect I've noticed: If you stop a print from the control panel, and then start it again [as opposed to a resume], when the heads move to the dump bucket, they miss, hitting the back on the right, as if the head offset is applied twice (or something). If a print completes normally, a successive print is ok. I'm using Alex's RC7 dual MBL firmware, and (I think) the latest profiles. Has anyone else experienced this?
