Slicer generation a ridiculous movement speed.

Here is the beginning of my gcode.
G21 ; set units to millimeters
M107
M190 S65 ; wait for bed temperature to be reached
M104 S210 ; set temperature
G28 ; home all axes
G1 Z5 F100 ; lift nozzle
M204 X3.65 Y0.09 Z36.0 ; temperature stabilizer

M109 S210 ; wait for temperature to be reached
G90 ; use absolute coordinates
G92 E0
M82 ; use absolute distances for extrusion
G1 F6000.000 E-1.50000
G92 E0
G1 Z0.300 F12000.000
I have it set up so that the printer homes, lowers the bed, and then raises the bed to start printing. However, slic3r is generating gcode that tells it to move G1 Z0.300 F12000.000 which is wayyyy to large of a number.Does anybody know where the setting is to change this? I've looked everywhere for it.
Thanks!

This is your travelspeed which you probably set yourself in Slic3R speedsettings to 200mm/s (12000mm/min), your retract speed may also be way too high (6000mm/min)
Speed is yet restricted in firmware/EEPROM max settings, you may check this.
