Davinci Super and Simplify3D (scripts and gdoce help)

Hello

I 've bought a new Davinci Super, from which i am super satisfied so far: Reliable Prints, fixed some hardware issues, nice lcd screen, large prints etc. The only thing i can't handle is the S3D to control the machine. The main issue is that i cant enable the fans whatever values i give to the process.. If anyone has solved this issue i'm glad to hear.

in addition, i'm trying to print a multicolor part but i cannot make it work from gcode. What i mean is i tried the
{REPLACE "; layer 15, Z = " "\nG1 X10 Y5\nM0\n; layer 15, Z = "} script but the only thing that the nozzle do is to go back to home position and then continue to print.. The hard solution is to pause the print from the LCD manually but this destroys the accuracy of the print ( half layer black - half white)

Please help..

Update: The fan problem is sovled from Simplify3D. You have to add on start script ( on scripts Tab) the following code

M107
M106 P3 S1
M106 P4 S1
M108

then the fans will start before start printing.

u cant, though, enable them on a specific layer (or height)

Does anyone else have bought a DaVinci Super, or im the only one here???
