    I installed a 12864 Full Graphic LCD Smart Controller a couple days ago and everything is working great, except for the stop button. It will stop the print job, but not sure what else is going on. It locks up the display when I press it and does not respond anymore. If I connect using Matter Control it will reset it (shows the start up screen/logo) or by turning the power off and on again. I have searched everywhere and I can't seem to figure this one out. Any help would be appreciated.

    This is what I purchased...

    This is normal behavior for the stop button on the LCD Controllers (Smart and Full Graphics). The button is meant to be an emergency stop so everything freezes instantly. The firmware has to be reset before it will function again.

    I have my smart controller on the way. Just wondering, the emergency stop button turns off all heaters before it halts doesn't it?
