Curious what I do wrong.
Button currrently controls up and down movement of the stepper motor.
Code works but as soon as I uncomment a line related to serial.print it also stops to work correctly.
I need the combination as I use the stepper to compress a spring and measure the force and the current position which need to be send to a PC application.
Am I asking to much from this combo?

}
I send a reset signal from the Arduino to the program on the PC so it knows we can start to measure.
