What I need to see is the code around a tool change part way into the print, not the start of the print.
slic3r has a checkbox called "Relative E distances" or something like that. Using that will probably solve the problem.

If you are going to do a manual tool change in the middle of a print, using different extruders on the two tools, then you must use relative extruder coordinates in the gcode file.

Sending the M567 to change the mixing ratio of a sellected and active tool makes more sense. This I know I can do!!! Awesome. I will try this and see what happens.
As I think about it I don't really need to do a retraction and unretract with the diamond head since oozing from another head is not an issue. Simply change the extruders ratios from the command line or drop the M567 code into the print gcode!

How have you defined your tools? Have you enabled mixing as well as setting ratios? This is how my tools are defined in my config.g.
M563 P0 D0:1:2 H1 ; Define tool 0 with all 3 extruders
G10 P0 S-273 R-273 ; Set tool 0 operating and standby temperatures (initially to be off). No x y offset needed as it's the same nozzle
M567 P0 E1:0:0 ; Set mixing (for tool 0 I use all extruder 1)
M568 P0 S1 ; Turn on mixing
M563 P1 D0:1:2 H1 ; Define tool 1 with all 3 extruders
G10 P1 S-273 R-273 ; Set tool 1 operating and standby temperatures
M567 P1 E0:1:0 ;Set mixing (for tool 1 I use all extruder 2)
M568 P1 S1 ; Turn on mixing
M563 P2 D0:1:2 H1 ; Define tool 2, with all 3 extruders
G10 P2 S-273 R-273 ; Set tool 2 operating and standby temperatures
M567 P2 E0:0:1 ; Set mixing (for tool 2 I use all extruder 3)
M568 P2 S1 ; Turn on mixing
M563 P3 D0:1:2 H1 ; Define tool 3 with all 3 extruders
G10 P3 S-273 R-273 ; Set tool 3 operating and standby temperatures
M567 P3 E0.34:0.33:0.33 ; Set mixing (for tool 3 I use equal proportions of all 3 extruders)
M568 P3 S1 ; Turn on mixing
Then in my start gcode (i.e. what slic3r puts at the beginning) I have
M83; Set extruder to relative
G10 P0 S205 R205 ; Set tool 0 operating and standby temperatures to 205 degrees (for PLA)
G10 P1 S205 R205 ; Set tool 1 operating and standby temperatures
G10 P2 S205 R205 ; Set tool 2 operating and standby temperatures
G10 P3 S205 R205 ; Set tool 3 operating and standby temperatures
and my end gcode has
G10 P0 S-273 R-273 ; Set tool 0 operating and standby temperatures to minus 273 which effectively turns it off
G10 P1 S-273 R-273 ; Do the same for the other tools.
G10 P2 S-273 R-273
G10 P3 S-273 R-273
So we have 4 tools which all share the same heater (and nozzle) so the only difference is the extruder, or combination of extruders. As the mixing ratio is initially defined in config.g, it can then be changed "on the fly".
There is no need to do anything else on tool change. Providing the tools all have the same operating and standby temperatures, there will be no delay when changing tools.

I was curious how your extruders are pluged into the Duet and Duex4 since you have set up drives 0, 1 and 2. I am set up on 2, 3 and 4 since I could not get the first Duex4 terminal to work. Likely due to my set up.
Thanks,

Perhaps you have a Duet 0.8.5 and deckingman has a Duet 0.6? The numbering of the DueX4 drivers and heaters depends on which version of Duet it is paired with.
