    I followed this thread to replace my ramps board.

    http://community.robo3d.com/index.p...and-rewiring-to-make-generic-ramps-work.8356/

    Everything is moving. The exturder I'm having issues with.

    The default step is 800, was causing it to run circles beyond belief. I turned it way down to 100. Looks to be about normal to where it was before I switched boards. Now I get the awful grinding noise. Not sure what is causing it or where to begin. I think it is coming from the motor.

    Please help.

    On the R1 default steps for X and Y are 80 not 100, What exactly did you change?

    X, Y and Z are fine. I changed the extruder from 800 to 100. I haven't calibrated more than that because of the noise.

    When we say the extruder should be at 800, it really should be 800. Make sure you do not have anything but Marlin defaults stored in EEPROM, from a terminal prompt issue the following two commands
    Code:
    M502
    M503
    the first one reads all the default settings from the firmware, the second stores those settings in EEPROM. From there you can go about tuning the Extruder, but I am 100% certain that 800 will be very close.

    Well that got me back to the base settings. The noise is gone, but I'm still moving to fast. 1mm advancement spins my gear a whole revolution.

    Here is a video. I have a dot on the gear so you can see how fast a revolution is.

    *Apparently my video didn't upload from my phone. Trying to find a different way to get it up here.

    I am not sure what you are trying to show here, that it spins? Okay, but you need it to spin the correct amount not just spin. What version of Marlin are you using? None of the Robo supplied firmware has esteps of 800, they are all 723.32 or some such number. If you downloaded one from this board, esteps of 800 is closer. That would mean you edited this line in the firmware:
    Code:
    #define DEFAULT_AXIS_STEPS_PER_UNIT   {80,80,800,723.38}  // default steps per unit for RoBo 3D R1
    and made the last parameter 100? Or, did you change the 3rd parameter 800, which is zsteps?

    If you changed the last one then follow this guide:

    I have not modified Marlin. I wouldn't know where to begin. When I boot up it says vers 1.1.0 - RC8. I tried reflashing with the Marlin I have and still no luck. The extruder is spinning 8 times as fast after I tried going to this generic ramps board.

    When I search the Arduino Files for
    #define DEFAULT_AXIS_STEPS_PER_UNIT

    The un-commented out line I have has these values. { 80, 80, 800, 800 } //--ROBO-BH Default steps per unit for RoboR1+PLUS

    If I try calibrating it wants be to see the e, the 4 value, to about 100.

    I put jumpers under X,Y and Z. Should I have jumpers under E0 and E1?

    Yes, every stepper driver should have the jumpers underneath them.

    That did it. Thank you.

    I think I see what I missed in the build log. It talked about jumping all 3 per stepper, then talked about XYZ.

    Thanks again.

    Without all those jumpers you lose the microstepping for the stepper and the steps/mm will change (a lot). Nice catch.
