KISSlicer Issue - SD3

I am using nickythegreek  KISSlicer settings (http://www.soliforum.com/post/14077/#p14077); One exception is the “Printer tab”: Bed Size and Offset: 200x200x200 and 100x100x0; Also, I added the following G-Code Prefix from my SD3:

M107
G21; set mm units
G28 ;home all axis
G90; set absolute coordinates
G92 E0; reset extruder distance
M104 S200; set extruder temp and start heating
G1 Z5 F300 ;move platform down 5mm
G1 X195 Y195 F3000 ; move to back right corner
M109 S200; wait for extruder temp to be reached
G1 Z.3000 F200 ;move platform close to nozzle
;G1 E7; extrude anchor
G1 F3000; center print head
G92 E0; reset extrusion distance
G90 ; use absolute coordinates
G21 ; set units to millimeters
G92 E0
M82 ; use absolute distances for extrusion
G1 F4500.000 E-1.00000
G92 E0
G1 Z0.300 F3600.000

When I send the print from R/H, the printer performs all my G-Code but when is going to start to print it lowers the platform and the extruder does not extrude any filament while “printing”.

Any help will be very much appreciated.

Thank you in advance for your help,
