I edited my gcode file to have

G28 XY
M0

so I could drop a magnet into a cavity in the print. The extruder does go home and the print pauses...but I can't get it to re-start. On my Dreamer's control panel the pause button stays at "Pause;" it doesn't recognize that the machine is paused, so I don't get a "Play" button. My only other choice at that point is "Stop," which doesn't really help...
