SD card inserted!

I use a full graphic smart controller and ramps1.4 , when I switch the printer on it says SD card inserted, while there is no sd card inserted. when I insert an sd card, nothing changes. when I rotate or click the rotary switch it doesn't behave normally, I have to click and hold it for several seconds for a click, and I have to rotate it for several turns to have a step move in the menu. also it doesn't keep moving to the end of the list, only changes between to first menus.


  • Then you have enabled sd detection and it is not working - maybe it needs to be inverted or pin set to -1 for none present. What happens is that it continuously tries to read not existing sd card eating up a lot of cpu power making everything very slow.
