When I first fired up my printer and for weeks after that, the emergency stop button in Repetier would, when clicked, cause the print to immediately stop and my PSU to immediately power down (stayed on but output was minimal). Now, for some reason, when I click it, the printer just keeps going for several more seconds. I usually have to click it twice to get any kind of halfway quick response from it. And the fan on the PSU keeps running which makes me think the heat bed and/or extruder are still drawing power even after the motors have shut down.
Anyone know why it might have started acting like this?
