Hi. I made a coil winder with a x axis stepper motor turning a ball screw linear stage to move a wire guide left and right. The Y axis is a motor that spins a bobbin on its shaft. The X moves the wire back and forth while the Y axis spins the bobbin. The X axis homes when powered up as it should. The buttons, buttonPin and buttonPin2, work as they should but one time only. After that the buttons do nothing when pushed. I have set the layers to low numbers for quick testing. There are no errors when verifying. I’m not sure if I’m over looking something or maybe I have somehow messed up my Arduino UNO. Any help would be appreciated.
