@cairnus how to mark text as code: Start a blank line with three back-quotes ` (upper left of the keyboard, below the tilde) #include <AccelStepper.h> int pin_en = 5; int pin_direction = 7; int pin_step = 6; int pin_reset = 39; int pin_voltage = 8; int pin_fault = 38; int microstep = 1; end with a blank line and three back-quotes as well. cheers!
