    I just installed the ramps 1.4 and was wondering do I need to change the firmware because when i plugged it in, it thought the second extruder motor was the z even those both z motors are going to the z plug on the ramps.

    What machine?
    The Robo R1+ uses the second extruder as the second Z. Regardless of reloading the firmware that will not change.

    This was a choice when they designed it. The normal Z output on the RAMPS can support two Z steppers and has two outputs, but they chose to use the second extruder output for one Z stepper and the normal Z output for the other.

    Don't have an R1+ to look at so I can't say which stepper went to which output, but it shouldn't matter.

    It doesn't matter to the firmware which board you use :)

    However, you do NOT have to use the second extruder for the Z, there are two stepper outputs on the Z -- use those. They should both be driven the same anyway.

    Yes, if you plug both Z steppers into the one stepper driver that is normally the Z then they will work fine.
    Granted, the R1+ PINS.H in the Marlin firmware* will probably keep sending a duplicate signal to the second extruder ;)

    I am not sure what exactly would need to be edited to fix that without research (which I have not done).


    *that is where the physical output pins for the RAMPS is defined for a given motherboard definition.

    Should i add a second extruder code on the configuration.h tab in the firmware. I'm pretty sure thats what novice tech tips.

    Like I said I have not modified an R1/R1+ for dual extrusion, but certainly there are things in the configuration that must be changed in addition to the output pin definition getting changed. You can't use the Extruder 2 port as longs as it is being routed to a Z stepper

    Use the r1 firmware and change your z steps to r1+. I think thats what i did when i did dual extruder set up (still not worth it)

    Sure, not a huge difference in any of them, but use the most recent.

    I personally think you should ditch the idea of dual extruders on the r1series

    But if your determines to do it then yes the most recent r1 firmware. Be aware most that have done it are long gone from the forum so youll have little to no help when you have issues

    wait so you said use the r1 firmware, the r1 firmware does not have the auto level and most of the code the r1 + has

    Ok i have figured this out. if you go into the r1 + firmware, there is a setting which you can change that you can change what type of board you have and how many extruders you have, so robo have thought about my situation already

    1) The R1 has autoleveling just like the R1+
    2) The Robo folks did NOT write the firmware :)

    Personal opinion is its a waste of time for not enough quality. Not trying to deter and wish you the best of luck :D
