Problem with the result

Hi!

I have upgraded my mill with a reprap controller board.
When I test it with a simple job, I get strange results, instead of a square I just get a simple line divided in three parts. The result is attached below.

M3 
G21 (All units in mm)
G00 Z5.0000 
G00 X0.0000 Y0.0000 
G01 Z-1.0000 F200.0000
G01 X15.0000 Y0.0000 F200.0000
G01 X15.0000 Y15.0000
G01 X0.0000 Y15.0000
G01 X0.0000 Y0.0000
G00 Z0.0000
G00 Z0.0000 
G00 X0.0000 Y0.0000 
M5 
(end)

I use ReplicatorG 0013 as host and reprap-gen3-firmware-1.6-r0 with custom config-file to match my controller-board.

It looks like my machine just increments the position value instead of using absolute position when moving.

Have I done something wrong in the firmware-file or in the setup of ReplicatorG?

It gives the appearance of being in 'relative' mode. See if adding "G90" to the top of the file helps. Mind if I steal your gcode and include it as one of the tests for the battery of GCode tests I'm compiling? Also, question -- what does M3 and M5 do?

Tanks!

By adding "G90" to the top everything works

Updated code:

(start)
G90 
G21 (All units in mm)
G00 Z5.0000 F200
G00 X0.0000 Y0.0000 
M106 (Mill relay on (fan on)
G01 Z-1.0000 F200.0000
G01 X15.0000 Y0.0000 F200.0000
G01 X15.0000 Y15.0000
G01 X0.0000 Y15.0000
G01 X0.0000 Y0.0000
G00 Z0.0000
G00 Z0.0000 
G00 X0.0000 Y0.0000 
M107 (Mill relay off (fan off)
(end)

The M3 and M5 commands is for controlling a spindle engine but I have replace it with M106 and M107 that control the fan on the extruder board. In my setup the commands control a 230V relay on my custom extruder board for my mill engine.
