I am writing some g code for my diy 3d printer. From what i understand g04 is dwell and its expressed in milliseconds. So my extruder takes about 30 seconds to heat up. Do i just type

G04 30000

You are correct about needing to specify the dwell value in milliseconds. However, the RepRap Wiki indicates that you need to use the Pn argument, and not just an unadorned number as the argument to the command. To adapt the Wiki's own example, you will need to use:

G4 P30000 

This should cause the firmware to dwell (pause) for 30 seconds.
