Timing of M163 color definition
I have a problem with the color change starting earlier than defined.
The pink (going from left to right) should start at the middle of the cube, but instead already starts at the left corner.
Checking with a gcode viewer the M163 command is placed at the middle of the cube, but looking at the extruders and the
end result I can see that it starts ealier than expected.
What might be the reason for this?
I only use one virtual extruder and when I change color I just overwrite T0 like this

M163 S0 P0
M163 S1 P0
M163 S2 P0
M163 S3 P0
M163 S4 P1
M164 S0
T0

And even then you will see a delay depending on how long it takes for the extruder to fill it with new color.
G1 X1
G1 X2
M163..
G1 X3
The color change in my case will appear before G1 X2, though it's set to change AFTER G1 X2.
Is there a fixed amount of advance?
I'm aware of the delay caused by the mixing chamber and thought maybe repetier tries to preposition the color change so there is less material to wipe?!
I will try with M400 and check the seam? Using the newest dev version will help, because of the improved advance feature?
I could not see any visible pause or blob forming.
