USB Cura print will not trigger auto-calibrate?

When I print the calibration print, and the Prusa logo from the SD card, the printer does the 9 point calibration, smears the test strip at the front left edge of the hot plate, then creates the border and finally prints.

When I print from Cura via USB, the printer appears to do nothing but find the home button and then begins the print.

What am I doing wrong?

Start GCode - Include G80 following the G28 (Home)

Is there no way to get Cura to add that automatically as a default option? Or do I need to do it with a text editor with every file I make?

Not using Cura at the moment, so I can't really assist any further. WHich Cura version are you running?

Peter;

Thanks for the G80. At least that's somewhat better.

Is there a code to make it do the pre-print smear at the front left edge of the bed?

Cura 2.1.3 Beta, linked from this site.

I only have Cura 15.04.6 - which works quite nicely.

Here's the start code to draw a line:

M83 ; Relative extruder
G1 Y-3.0 X50.0 F1000.0 ; go outside print area
G1 X100.0 E5 F1000.0 ; intro line
G1 E-0.5 Z2 F1000 ; Retract a bit and lift nozzle
G92 E0.0 ; Zero extruder

The codes are reasonably well documented.
