Hello! I am very new to RepRap and am trying to implement the Marlin 1.0 firmware in a personal project which mimics a 3D printer, except that it uses an airbrush to make art. I have a Sainsmart RAMPS 1.4 board atop a Mega 2560, with a single stepper driver plugged into the X axis. As I will not be using an extruder nor a heatbed I have neither plugged in. Additionally I have a Smart LCD Controller (with rotary encoder). The latter works correctly.
However, when I attempt to move the the motor that is plugged in, with stepper motor plugged in, nothing happens- the motor doesn't act at all. Additionally, a thermistor reading on the LCD controller is coming up as 498-500 degrees despite the fact that nothing is plugged in there (as my project will not need it.) Can anyone lend a bit of advice as to how to get at least as far as the "spinning motors" stage? Thanks in advance =)
