Prusa I3 MK3 - Crash after first layer of raft

[Sylvian]

Hi there,

I just receive the last model from Josef Prusa, the Prusa I3 MK3, an awesome product working well with his own slicer (named Slic3r), but this software is having a real poor render than S3D, then I've try to use S3D (as usual with Prusa I3 MK2S) but this time every print i've try to made witf a raft is crashing after the first layer:




As you can see in screen this appear to be linked with fan.

I'm not an expert with gcodes, so here are the two gcodes for the same sliced 3d object.

Gcode generated by Slic3r (working well) : https://puu.sh/yQh0L/7e62b4afc4.gcode
Gcode generated by S3D (crash on 2nd layer) : https://puu.sh/yQh2z/29413aa1b7.gcode

I can made some try if a developper would try to fix it

Thanks for your help.

However,
I can't download your files but I see in the S3D-Code that you begin the First Layer at Z = 1.00 mm.

If it is a normal calibration, it MUST crash!!!

G92 E0.0
G21 ; set units to millimeters
G90 ; use absolute coordinates
M83 ; use relative distances for extrusion
G1 Y-3.0 F1000.0 ; go outside printing area
G1 X60.0 E9.0 F1000.0 ; intro line
G1 X100.0 E12.5 F1000.0 ; intro line
G1 E-0.8000 F1800
G1 Z1.000 F1002
; process Process1
; layer 1, Z = 1.000

This is normal, I move the object 1mm upper for technical reason, it should build support to avoid it, no link with crash, the same thing happen when it was directly on the bed.
