    Hello everyone,

    I’m having some difficulty getting the hardware to work correctly.
    Only one acces / motor is responding and I’m not getting any information on the smart lcd screen,

    So per the title question I have, does the Arduino firmware work with mega 2560 and ramps 1.4 ?

    Or would I be better off getting s ramps board?

    hi @richyrich140db2000

    I am also trying to build one with ramps board for sometime. finally managed to work it (almost)
    problems I have encountered:
    power problems:
    I have tired different power suplies. finally got it working with 12V 5A power supply / quite not sure with wiring though… just using 11A sockets for now

    it took me couple of days to realize that I have did not put jumpers under one of the motor drives. (motor was just vibrating)
    also in order to power servo, I have to put a jumper to 5a/vcc slots (they moved it to a different place on different ramps versions (also took 2 days to find)
    and I am using a big servo / I think it requires more power and causing problems (I will try a micro servo)

    LCD was not working / first it was due to power&usb cable problem, and later because of using wrong sockets ( I am using the original LCD Dan sent)
    I still cannot drive motors with LCD..

    my mega is cheap chinese model, it is not working with mac, I managed to upload the firmware with mac but makelangelo software never sees it on mac 🙁
    also have problems with usb cables…
    also in my first attempt I burnt my ramps MOSFET’s

    right now I am dealing with

    now motors are working / although moves up instead of down / but I think there is solution somewere on the forum
    and motors are moving faster!!! instead of 1cm they move ~3cm

    hope this helps

    >although moves up instead of down

    with power off, reverse the connection. if the wires are rgby, make them ybgr.

    > motors are moving faster!!! instead of 1cm they move ~3cm

    probably still missing a jumper under a driver. all three jumpers should be on for 1/16th microstepping. if your board somehow supports 1/32… then you have to adjust.

    im been using Arduino Mega Board with RAMPS 1.4 with cheap or clone Futaba S3003 servo motor since September 2017… its work flawlessly till Jun 2018 as the Futaba stop working randomly after 1 hour or less.. id bought so many Futaba & even upgrade the makelangelo firmware still the new Futaba stop working after 3 hours.. maybe there is some sort of electrical short from Futaba to RAMPS board since there is some glitch or when that servo motor connected to RAMPS the whole system when hang!.. LCD cant display properly etc… it when good after id disconnected that servo motor..

    i did try it using few new Arduino Mega (CHina Clone) & the problems still arise…

    now im trying to use MKS BOARD V1.4 to see if the board really good handling Servo Motor connection (power distribution or PWM etc).

    Thank you for the reply’s

    I’m glad to hear that it can and should work, so now I just need some help.

    Question for you Bulp, could you share your config sketch file ?

    I believe somewhere in the config file something is missing.

    Thanks again for the reply’s and any help you can give,

    Hi richyrich140db2000, i do believe that the latest firmware didnt tweak very well for smartcontroller LCD as per firmware before Jun 2018 that really work well with SmartController that have built in SD Card.

    apparently i do get prompt with command that need to enter from smartcontroller.. id try to disable to define has LCD & SD from firmware but still the command appear.

    id just define the type of polargraph & using RAMPS, thats it.. other than the LCD problem im still waiting for Dan to fix it.

    April 18, 2019 at 11:23 #23029

    It is not clear to me what is your LCD problem. Please list the steps to reproduce it. Thanks!

    Hello Dan,

    The problems I’m having is:

    only 1 motor is responding on X access no other access has power output and the motor is putting out a annoying high frequency humm. Yes the stepper driver power has been adjusted.

    The Lcd display I’m using is the “reprap smart lcd controller with built is SD card reader”. It gets power but dose not display anything and the built in speaker puts out a high frequency dog whistle sound. It’s annoying as hell.

    What pins should I use for the servo?

    Thanks again for the help.

    It’s not enough information to determine the cause of the problem. If it was just one motor I’d say the wiring is wrong on that motor OR the driver is dead.
    The reprap smart LCD controller is supported, so it’s either wired wrong, setup wrong in the software, or something else. Process of elimination.

    Hello Dan,

    I did a Makelangelo Bot by Ramps 1.5 + Arduino Mega 2560 yesterday. I uploaded Makelangelo firmware 7.20.1 for my bot successfully. In Makelangelo software, I can control stepper motor move and servo up/down, but when I upload image file and press Start/Start at line, the bot isn’t work. Can you help me? Sorry for my English. I’m from Vietnam.
    Notes: I’m using 11A socket in ramps board.

    If you have no LCD panel then in configure.h uncomment

    #define HAS_LCD

    and upload again. The machine waits for you to press a button on the LCD to confirm the pen is ready to draw before starting. With no LCD panel, there is no button and the wait will be forever.

    Hi Dan,

    MY ramps is finally working
    but in makelangelo software my new makelangelo has the id “-1” and everytime I connect it I have to change the machine settings and machine size.


    April 30, 2019 at 12:18 #23139

    When you connect the software to your machine it should assign a unique ID number to that device and register the machine with my server. This is a once-only thing so I can count how many Makelangelos are in the world: https://www.marginallyclever.com/makelangelos_over_time.php

    Either your machine is not phoning home; not connected; or some other problem.

    Dear Dan,

    I uncommented #define HAS_LCD and upload again. But the bot still not work when I press START/START AT LINE. However, I still controll servo and stepper motor move. Help tell me what is wrong?

    Code in configure.h
    // LCD panels supported

    //#define HAS_LCD // if you have an LCD panel
    #define HAS_SD // if you have SD card support on your LCD panel (must be on panel?)

    // only uncomment one of these options
    //#define LCD_IS_128X64 // reprapdiscount Full Graphic Smart LCD Controller
    #define LCD_IS_SMART // reprapdiscount Smart LCD Controller (including XXL model)


    May 1, 2019 at 09:13 #23150

    makelangelo-firmware.ino, near line 740, check it is written:

    void waitForPinState() {
    #ifdef HAS_LCD
    int pin = parseNumber(‘P’, BTN_ENC);
    int pin = parseNumber(‘P’, -1);
    if(pin == -1) return; // no pin specified.

    in the previous version the last if was not there.

    Dear Dan,

    My bot worked successfully. Thank you very much ^^.

    Hi, Dan.

    I get some problems. First, I use Makelangelo V3, so when I press Go Home, the bot move any location and stop. Second, what is ratio between loads which you hang on timing belt and bot? because when the bot move, sometimes it’s sliding step (between pulley 20 teeth on stepper motor and timing belt GT2).

    May 5, 2019 at 10:12 #23198

    M3 only has “set home”, when the pen holder is already at the home position. There is no automatic find home on the 3.

    The Center weight we use is 200g. The outsides are 100g each.
