    Mike.. All...

    I've competed all the hardware changes for the Chimera but am so far unable to get the new, second cold section to run.. both nozzles on the hot section are working perfectly...

    (yes Mike, I put in a 5th stepper driver) :)

    I followed Mikes google notes on the firmware changes but was unable to do the last one (which I am assuming is my problem) I downloaded the firmware source from the Robo3D website (comes up as AUTOV5 on the LCD).
    The last change in the instruction is:

    Configuration_adv.h
    #define EXTRUDERS
    1 -> 2

    I have been unable to find that in Configuration_adv.h Neither does the Arduino IDE Edit:Find

    any ideas? anyone?...anyone?.....

    I've found MANY odd deletions/errors in presumed "original" firmware packs but wrote those all off to hamfisted changes by person or persons unknown (the fortunate results of open-source) but would expect the factory download to be clean.

    I found it in a couple of places in that file:

    #ifdef Z_DUAL_STEPPER_DRIVERS
    #undef EXTRUDERS
    #define EXTRUDERS 1
    #endif


    is one example.

    Not sure what version of the source you are looking in, I was looking at the 6_10 version.

    My bad, that was in configuration.h

    All the configuration_adv stuff was ultimately unneeded

    ya, but that's top use two *drivers* from Z, instead of just running in parallel

    If you swap motor inputs can you get the motor to run?

    Fixed.
    Turns out the second extruder was working all along, I was merely fooled by the XXL LCD panel not showing two extruder in the manual move section... using S3D's jog controls showed it was working. Thanks Mike K for that suggestion.
