    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

    jumpers
    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..

    arduino:
    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.

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