    – added command line input under etch-a-sketch controls
    – moved ./java/windows to ./last_official_release/windows
    – moved ./java/OSX to ./last_official_release/OSX
    – updated README.textile to explain new layout

    If you are trying the very latest new release to see if it fixes a bug, use ./java/Makelangelo.jar

    Tomorrow I’m working hard on documentation for the Makelangelo 2.5 (a cheaper, slower version) and the Arm3. Taking care of customers eats a lot of my time but it’s worth it!

    Testing now!
    Stalling issue again. Pause/unpause helps a bit.

    I tried a few combinations, actually.

    Firmware+software from last_official_release folder stalls but finishes eventually.

    Firmware from arduinofirmware_ams1 + software from java folder is very unstable. BADLINENUM constantly appears

    pkm –

    To confirm: movement stops, then you’re pausing / unpausing from the Makelangelo software?

    What’s the last thing in the status window before you pause/unpause?

    I’m still expecting the shield so I’m trying without any. Just Uno, so I don’t know what happens with the motors.
    But as I expect AMS1 I use its firmware.

    So the line counter just stalls, usually without any messages.
    Just like this

    I would try to upload Rumba firmware and connect step/dir outputs to pololu drives. But the latest Rumba won’t compile

    Can’t run the jar file. It is missing the RXTX (or whatever) lib.

    Either put that jar to last_official_release folder, or copy the files from there

    The next time it stalls like this
    I don’t understand why it breaks the response lines so unexpectedly

    Sorry for the large pics, just tell if I shouldn’t post them

    The large pics are fine. You can also link from imgur.com if you like.

    To get the RUMBA to compile, set your board to MEGA 2560.

    I bet the arduino is answering but somehow the “>” is never received by the PC. I need to add a timeout ping so the arduino can say “Hey! I’m still alive! Want me to do anything?”

    Oh, thanks!
    Now I have AMS1 on my Uno and Rumba on my Mega.
    BTW please add #include “SPI.h” to all firmware, it won’t compile on Arduino 1.5 without it.

    We’re still running Arduino 1.0 here. I will look into upgrading. Thanks for the tip! I’ll put your name in the source code for that fix.

    AHHH… we may have found the problem. I’ll try downgrading to 1.0 and see if it works.

    Aha… I’m checking too.
    Stalls again. That’s not about Arduino 1.5.

    yep no luck here either.

    One thing I haven’t tried is the SD card. I don’t have a reader nor do I know how to run an SD card from a rumba.

    So you have roomba?

    i-make-robots
    Is it possible to connect LCD with SD port to ams1?
    Actually I was thinking more about RAMPS board.
    I’m sure RUMBA firmware can be adjusted pretty easily for RAMPS.
    So: RAMPS + 2 pololu + LCD with SD.

    Can you say if e.g. this LCD will be OK?

    BTW why I’m here: I made a simple drawbot with LinuxCNC. But I’d prefer something cheaper and more simple, so I turned to Arduino. And your project is very good!

    Yeah I see you have an uno[?] so it must be something to do with the software then.

    pkm – I added spi.h to my local build, will upload soon. I won’t move to 1.5 until it is the official release. Let someone else handle the bugs for me.

    I can’t say 100% if the LCD will work. It should! If you find the pins are different, let me know. The LCD code only exists in the RUMBA version of the firmware. The main reason the two firmwares are separate is because the UNO isn’t capable of handling some of the features on the RUMBA like the look-ahead code. What you save in $ for the board cost you lose in features.

    I have both Uno and Mega256.
    Do you observe these strange line breaks too?

    Always different location.
    Could it be some random transmission errors?

    i-make-robots
    First include will be OK. I already installed 1.0 but I’ll check the next release on 1.5. Thanks!

    One day soon I’d like to combine all the firmwares into a single version

    That would be very nice!

    Oh, like this…
    But Mega256 is more powerful than Uno? Actually RUMBA has ATmega256 too, so it’s ~ equal to Mega256 board?

    Yes I do.

    How does java wait until the robot finishes a line of code?

    If I am correct it should:
    Java sends line to robot.
    Waits.
    Robot processes line.
    send a completed command[?].
    Java receives command from robot.
    Java sends the next line.

    Are we the only one’s getting this error? Is the creator? The SD card that came with my robot is not working so I’ll need to find another to test if the SD card method works.

    I guess there’s a queue (traced green on the preview), otherwise you are right, there must be transmission acknowledgement.

    Chances are good for SD card to work as there’s no communication to PC in this case.
