Cura first gcode generated is retraction ?

Recommended Posts

My prints does not start immediately, due to the fact that it does not have filament, even if I print a huge skirt, and I mean huge. I then saw the very first gcode  generated by Cura is 5mm retraction

 

G92 E0.0                           ; reset extruder distance position

; end  startup code
G1 F2400 E-5
;LAYER_COUNT:51
;LAYER:0
M107

 

5mm retraction ? , I have a Crealiry CR10 4S, and a bowden need a lot of retraction, how can I switch this off, because this is the reason why the print does not start immediately. Currently I edit the file, but tends to forget and then the print is a flop.

 

Thanks

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
