[difficulty printing with ender e3]

I have an ender e3 and am trying to set it up with cura. However, the first layer always prints to high and does not stick to the bed. I have ensured that the printer is calibrated and the built in prints work.

 

Here is my start code:

G28 ; home all axes
M117 Purge extruder
G92 E0 ; reset extruder
G1 Z1.0 F3000 ; move z up little to prevent scratching of surface
G1 X0.1 Y20 Z0.3 F5000.0 ; move to start-line position
G1 X0.1 Y200.0 Z0.3 F1500.0 E15 ; draw 1st line
G1 X0.4 Y200.0 Z0.3 F5000.0 ; move to side a little
G1 X0.4 Y20 Z0.3 F1500.0 E30 ; draw 2nd line
G92 E0 ; reset extruder
M117 All systems go!
