[Nozzle starts too high when I slice with Cura]

I think I'll stick to Simplify3d, I made the changes you advised and still no avail.... The only problem with Simplify is it can have finicky slices, where a wall will print perfectly with one model and not another. Perhaps these could be some of the model designs as well?

oops heres the gcode without the semicolons

[Nozzle starts too high when I slice with Cura]

I sliced with simplify3D and printed with Cura and it worked. I'm not sure what cuts is going to make the print head start at the wrong height

[Nozzle starts too high when I slice with Cura]

I also tried reprap g-code flavor with no avail. I don't understand why the printer extruder height is correct when I home Z and yet the printer starts printing way too high to even adhere to the bed. 

[Nozzle starts too high when I slice with Cura]

yes i have prusa as the printer type

[Nozzle starts too high when I slice with Cura]

Hello all,

 

I'm hoping you can help me, i have a prusa i3 V2 printer and have used Repetier for a long time. I want to start using Cura and have everything communicating correctly. I leveled my bed and when I home Z it's adjusted perfectly with a pc of paper. However when I slice my model and start printing the nozzle is about 1mm away from the bed. Attached is my gcode for a simple 20x20 cube. Can someone offer insight? 

 

PS I tried both Marlin and Repetier in terms of the G-Code flavor and get the same results.
