I just bought a Slash OL from another hobbyist and when I turn the slash on, I hear a constant motor “whirring” sound. The sound won’t go away unless I click “Show Logo” in the printer tools. Once I do that the printer is nice and quiet until I turn it off and back on again. I’ve confirmed that the motor sound isn’t the pump or the z-axis, so not sure what it is. The printer works fine either with or without the sound, but it is very annoying. I’ve updated to firmware 4.5 but that hasn’t helped. Has anyone else experienced this?
