Want to do a "pencil" dry print, but will not do x and y movements after the carrage is lowered to z = 0

Hello all,

I've got a Rostock printer built up and connected except for the Extruder motor, Extruder hot-end and the hot bed.
I want to do a calibration "dry-print" where I attach a pencil to the carriage and do a 2D print when Z = 0.

However whenever I upload a G-code using prointerface, it will not do the x and y movements after the carriage is lowered to Z = 0.

I home all axes as appropriately, then I upload the G-code (gear bearing to be precise: [www.thingiverse.com])
the carriage is lowered to Z =0, but then does nothing.

I assumed this is due to a safety interlock engaged due having a room temperature
value for the extruder and heated bed: the only safety feature I know is #define PREVENT_DANGEROUS_EXTRUDE, which has been commented out.


Here is the video of the situation:

My Config file is this:

I'm using:
Ramps 1.4
Marlin V1
24V 10A PSU
Two 100k neg-coff thermisters for the hotend and heated bed (not connected to either, just to test they work)

Appreciate any help.

Cheers!
