    Hello All,

    I have purchased a E3d v5 hotend a few months ago, and I am unable to get it to work.

    I have it wired correctly, my problem is that I am unable to modify the software correctly. I dont know what I could be doing wrong. I changed the default temp according to melodybliss. When I try to heat the head up to 300C, it goes to 239C then cuts off.

    On top of that, I dont know anything about programming, and I dont understand the stepper motor calibration part.

    Is there anyone who might be willing to help walk me through this process?


    I really appreciate your time.


    Thomas

    Can you give us more details on how you flashed the firmware? It sound like either you reflashed the old configuration.h file or nothing was downloaded. Below are the two changes needed for the 3/14/14 Marlin firmware from this post: http://forums.robo3dprinter.com/index.php?threads/marlin-firmware-update-3-14-14.1857/

    //#define TEMP_SENSOR_0 1 //robo, old setting commented out
    // Change for E3D hotend Semitec thermistor
    #define TEMP_SENSOR_0 5​

    //#define HEATER_0_MAXTEMP 240 //robo, old setting commented out
    // change for E3D hotend
    #define HEATER_0_MAXTEMP 310​

    After you install the Arduino software just unzip everything from http://forums.robo3dprinter.com/index.php?threads/marlin-firmware-update-3-14-14.1857/ to a convenient location. After you have the Arduino software installed just open Marlin.ino by double clicking on it. It may ask if you want to create a sketch folder named marlin, just say OK. Then follow the FAQ ...select the tools/board/Arduino Mega 2560, and click on the upload arrow. Eventual you will get something like "Upload Complete". You should be all set if I didn't forget a step.

    Yes good point, I figured that he had the beta one because he bought the E3D a few months ago.

    Yeah but the R1 has been out for "a few months" now so it's best to be overly clear.

    Really hate having different firmwares out there...

    Okay, thank you for all your replies. Yes, I have a R1 model. Sorry for not stating that earlier

    Alright, so I redid the flashing process. This time I hit upload, im an idiot haha.

    So, since I have an R1 pla/abs model, do I not need to do the stepper motor reprogram? I hope, I dont


    Thank you all again, for the help

    According ot Melodybliss
    "C.8 Recalibrate the X/Y/Z Steps in the firmware."
    This is what Im referring to


    Also, when i successfully flashed, and uploaded the temp changes. My heater only goes to 299.9C Is that going to be a problem?

    Now, I have another issue....go figure. My z axis sensor isnt working. The screw hits it, and it doesnt stop the motor. It keeps going on, and on, and on. Did I mess something up?

    Well, either your end stop switch isn't working or it is disconnected. I have broken my own repeatedly though I am sure you are not as clumsy as me. Jeez, I hope not. Anyway, I just re-solder and soldier on.
    The firmware steps I believe refers to the latest numbers contained in the latest firmware. If you flashed after the latest download, you should be set.

    You are very welcome for my sage advise;)

    X,Y and Z stepper calibration constants should be correct in that firmware. The only reason you might want to check the Extruder stepper calibration is if you change the hobbed bolt out. Grooved hobbed bolts will have a smaller effective diameter and tend to extrude about 95% of a non-grooved bolt. This may not be enough of a change to bother with. Here is one of many descriptions on how to measure the extrusion length: http://forums.robo3dprinter.com/index.php?threads/new-hobbed-bold-decreased-flow.2851/#post-23547

    Does anyone know if the the R1 is shipping with an improved hobbed bolt yet?

    I use matter control, then used the 6_10 flashing update that was recommended in this thread.


    Are any of these what you are asking, Mike?

    Okay, here is a little odd thing to happen. It seems somehow something got reprogramed. The Z axis is only lowering when the endstop micro switch is hit. It is doing the opposite to which it should. then the button is pressed, the z axis attempts to lower. Instead of stopping as it should.


    Is there a easy way to fix? All the wired are lined up properly

    Thanks again.


    PS 1D1, Yes I am far clumsier than you.

    I noticed the e3d v5 is no longer avail. The v6 should install the same. Yes?

    Cheers.

    Looking here :

    and here :



    I'd say it looks actually easier--they did away with the kapton tape fiasco.
