The purpose of the standby temperature is to prevent oozing. The standby temperature isn't normally controlled by the slicer, it's set by G10 Pnn commands in your start gcode. See http://reprap.org/wiki/G-code#G10:_Tool_Offset. I use a standby temperature of 150C when printing PLA, and in combination with some retraction in the tfree#.g file this is very effective at preventing oozing.

To set the standby temperature the same as the active temperature, in most slicers you can do something like this in your start gcode:

G10 P0 S[first_layer_termperature] R[first_layer_temperature]
G10 P1 S[first_layer_termperature] R[first_layer_temperature]

Alternatively, in your M563 commands in config.g you can declare that both tools use both heaters, then they will always both be heated to active temperature and they will both heat up at the same time.

Hi Pete, yes I think the problem is in the gcode at the start of the file. There are commands to set the tool temperatures but no commands to select tools until the first T0 command. Also it has commands like G1 T0 E8 but I have never seen a T parameter used on a G1 command before or documented anywhere.

You should aim for your start gcode to look something like this:

M106 S0
M140 S100
M190 S100
G10 T0 S220 R170 ; set tool 0 active and standby temperatures
G10 T1 S220 R170 ; set tool 1 active and standby temperatures
T0 ; select tool 0
G1 E8 ; prime tool 0
T1
G1 E8
T0

I have chosen a standby temperature of 170C in the above but you may want to adjust that.
Also, we recommend to select relative extruder coordinates if your slicer supports it.
