UM original retract on startup Cura 14.07

[qwarks 1]

Hi guys.

I have tried to use Cura 14.07 to generate gcode for my UM original.

I use prontrface to send the gcode.

The firmware is updated to the newest.

When i press print in prontrface the printer seems to start like normal, but when it gets to the middle of the platform to start the print, the extruder retracts like 20-30mm and then it starts to print - ofcourse nothing comes out.

Here is the beginning of my gcode:

Your start.gcode is missing a 'G92 E0' for resetting the extruder position before the first line with a print command (but after the G90).

It's also recommended to do some priming before print as it is done in the default start.gcode.
