    I try to to run Makelangelo on Mega + RAMPS + LCD.

    I changed the pins in Rumba firmware for RAMPS, and the motors seem to work.
    LCD works too but the contrast is low.
    The encoder won’t work though I changed the pins as described here (though the encoder button works)
    The lower button won’t work too, I don’t know how to configure it

    Any clues?

    If I remember correctly the lower button is hardwired as a reset button.

    I’ve just placed an order for more PCBs that includes some RAMPs boards. When it arrives I can better debug this for you.

    I’ve also ordered in hot ends and beds because it’s time I offer the whole 3d printer package.

    Great!
    I can send you the modified firmware for RAMPS when you start playing with it.

    Meanwhile I got it almost working. Only “disable motors” menu item won’t work. They’re always enabled as the board is powered up

    My cheap LCD has a low quality encoder, unfortunately. But it can be replaced, I guess.

    send me a pull request from github and I’ll merge it into the project. also that way your name will appear in the git commits, which might be good for you in future. (“so…what projects have you worked on?”)

    Never done that ) But I’ll try to figure it out.

    OK I got the encoder and its button working.

    As I said before, the motors can’t be disabled through menu.
    And I can’t see anything on SD card (though I can see and run those files with repetier firmware). I choose Start from file… but I see only Back link.

    Is it all working for you with Rumba? Maybe I picked some pins wrong?

    the enable pins on the motors might be different, but if enabling motors works then disabling should be the same.

    Are the files on the SD card in the root folder? It should list every file in the root.

    It’s also possible the pins for talking to the SD card are different on the Mega.

    The pins you care about are:

    #define SDSS 53
    #define SDCARDDETECT 49

    those are the numbers for the RUMBA board, they’re may be different for the Mega.

    I just updated RAMPS support in Arm2. Which robot are you using? I’d like to copy your settings to the code and improve support for everyone.

    I use Makelangelo.
    I’ve taken a pause for a couple weeks, did not have time to send a request on github.
    Here’s what I used for RAMPS https://www.dropbox.com/s/pdv22ll3ijbf6ft/firmware_ramps.7z
    It proved to read from SD, just doesn’t see folders.

    I added the pin settings in github commit #66. Thank you! Now I won’t blow up your system if I publish an update. When I mention it on the blog, can I link to your site, http://www.pkm.org.ua/?

    Sure you can. Too bad I update the site so rarely.

    Does it work for you with RAMPS? What about “Disable motors”?
    I had one motor rotating a bit strange, but I did not check anything. It might be the Pololu drive.
