Dual Color second extruder not printing

when printing using individual it all works well, but when I try to print the traffic cone in dual color, the second hotend doesn't heatup to print when it is suppose to

couldn't find anything on google

looked at repetier web site, I did everything just how it was shown on the video

I had to manual turn on the second heater and it all goes fine from there on

any idea???

another problem with this, when switching to extruder 2 it seems to extruder extra everytime but when switching back to extruder 1 it doesn't do that, this resulting a blob on every change to extruder 2

one problem solved on the blob, now just why doesn't the printer turn on both heater on the hotend and just one??

What does the start of your g-code look like? It should have two lines for turning on the hotends:

M107
M190 S95 ; set bed temperature and wait for it to be reached
M104 S250 T0 ; set temperature
M104 S235 T1 ; set temperature

If not, then your slicer setup wasn't right, but you didn't say which slicer you are using or how you used it.

I tho of that today actually that I forgot to add the gcode for second hotend, but been taking a break from it, will do that tomorrow, thanks for the reminder
