Hello. I had made prusa i3 and facing some problem. As I turn on my 3d printer the heatbed automatically start heating up without setting up the Max temperature. For reference i had upload the picture of my lcd(heatbed.png) after few minutes the 3d printer was on . I have 12V, MK3 Aluminum Heatbed and connected through heatbed power module. I had also upload Marlin Firmware. I hope if anyone can help me out. Thank you
