Next heat up your heat bed to about 100c by typing in 100 and
click the set button to the right of the bed temp. Confirm that the
heat bed temperature is rising and then click „Off“ once you know
its working.
Next you will test the hot end, first make sure the hot end fan is
turning, if its not make sure it is connected directly to the power
supply or the power input of the ramps board. Type 225 to the
right of „Heater“ and click set in the Heater Row, then to check
your temperature click the Check temp occasionally:
Once your hot end has reached 225c set your Extruder speed to
30 and click extrude.
If your filament gets pulled out of the hot end instead of pushing it
in then power off the printer and rotate the motor connector for
the Extruder Motor.
You should now be able to move your printer in all directions, but
your endstops will only be used when you click one of the home
buttons so don‘t keep telling your printer to go past that point.
Now you can print some Gcode, instead of copying gcode to an
sd card and printing via the LCD just load the gcode into
pronterface and click „Print“
