How to extrude a line before a print.

Hi all
I know can do all sorts with g code.
I have a simple question about the start of a print. I am using Cura and I want to extrude a line say 50mm long before the print starts as sometimes I don't use a skirt. I want to put a line say 10mm in the X asis (to make sure I miss the clamps) and 50mm long in the Y axis, does that make sense?

Thanks

Oh you mean like a prime line on the edge?

I know with the EZABL instructions, he has it do that...here's a cut / paste from beyond the startup and probing portion...

M117 Purge extruder
G92 E0 ; reset extruder
G1 Z1.0 F3000 ; move z up little
G1 X0.1 Y20 Z0.3 F5000.0 ; move to start-line position
G1 X0.1 Y100.0 Z0.3 F750.0 E15 ; draw 1st line
G1 X0.4 Y100.0 Z0.3 F5000.0 ; move to side a little
G1 X0.4 Y20 Z0.3 F750.0 E30 ; draw 2nd line
G92 E0 ; reset extruder
G1 Z1.0 F3000 ; move z up little
M117 Printing.....

Thanks Paul
I have tried it out and it works, I can tweak it as needed.
Every day I learn a bit more.
