    Alden and Riley,

    I just sent you a video that shows a loud clunk after routing a circle. This is the code that does it.

    There is nothing physically wrong with the machine. It seems to do this as it transitions from one sequence to another, like from curves to straight. I had some gear code where it clunked after each tooth. After seven or eight layers, it was half an inch off, ruining big chunk of nylon.

    This is why I was trying to update the firmware. Any ideas? I can’t continue to ruin materials and waste hours of time.

    Thanks. I’ll give this a run, but I’m pretty sure you are going to need to upgrade the firmware from 380.06. We’ve made a lot of progress since then. If you are so inclined you can update from the edge branch.

    #5183

    I would upgrade the firmware, but my attempts to do so have failed.

    I described the problem in detail in another thread. Basically, the installer crashes with no explanation, and no error code.

    #5184

    Here is what I said in the other thread about my attempts to upgrade the firmware:

    The stuttering bug has reared its head again, and TinyG damaged an expensive hunk of nylon. I’ve tried for the past two hours to figure out how to update the firmware, but I hit several roadblocks.

    First, you suggest using AVRdude that came with Arduino. I have Arduino, but no AVRdude. I can see the TinyG in the Arduino serial window. I can trigger boot mode by issuing $boot=1 from inside Arduino. But no idea how to use it to update the firmware.

    I installed AVRdude. After some path variable issues, and figuring out that I have to issue $boot=1 in CoolTerm, then immediately close it and issue the AVRdude command. But it crashes during the loading process. Ends in Failed, Failed, Failed a thousand times so that any useful info flies off the screen. And the logfile switch doesn’t work. If I redirect the STDERR to a file, it contains nothing. Frustrating.

    Which firmware? I went here:

    https://github.com/synthetos/TinyG/wiki/TinyG-Boot-Loader

    It lists this link:

    https://raw.github.com/synthetos/TinyG/master/firmware/tinyg/default/tinyg.hex

    If that’s not the right one, which one should I use, and where is it?

    >I’m pretty sure you are going to need to upgrade the firmware from 380.06.

    And in the most respectful way possible, can I ask where that firmware is located?

    🙂

    The .hex file is on the edge branch in the github:
    https://github.com/synthetos/TinyG/tree/edge

    in the firmware/tinyg/default directory. Don’t worry if you looked for it before and didn’t find it, I just added it back in. Also, I expect another push to edge in the near future – perhaps as early as this weekend.

    tgFX fails to communicate with this version:

    >[+]Connected to /dev/tty.usbserial-DA00CB3F Serial Port Successfully.
    >
    >Getting TinyG Firmware Build Version….

    And after that nothing happens.

    Seems like that rather than being an edge version it’s still a test version – $test=? commands only move Motor 4.

    #5194

    I should probably wait for Riley to get back from a conference as he’s the keeper of tgFX, but let me see if I can answer your question. The edge firmware needs to work with the tgFX edge, which is lagging the firmware by a bit. Please give us a few days to get these lined up and get a version of tgFX out there that works with the edge branch. Sorry for the confusion.

    In the mean time you can always drive TinyG directly from Coolterm, albeit without some of the nice features tgFX offers.

    #5195

    Sure, but even from the terminal I can move only Motor 4 so it’s pretty much unusable at the moment.

    I have already asked multiple times. What is the magic to update the firmware?

    The AVRdude instructions in the wiki are either wrong or incomplete. I have done it many times and every time it crashes in an error with no error log.

    I have updated firmware on many microcontrollers. It shouldn’t be this hard.

    UPDATE: I just added a wiki page that begins to document where to find the firmware, and I added a link to it on the main page. It amazes me that something so pivotal is not documented already.

    I appreciate your pitching in. You know, we work very hard on this and it’s quite disappointing when people are not satisfied. We are not getting rich off this, and it’s not our regular jobs. Any help we can get is much appreciated.

    >We are not getting rich off this, and it’s not our regular jobs.

    Hold it a second.

    Your site says very prominently that this is

      “Affordable INDUSTRIAL GRADE Motion Control.”

    Industrial grade means I can do meaningful work without destroying something. Industrial grade means fully-functional. You can’t claim TinyG is “industrial grade” and also that it’s okay it doesn’t work because it’s your hobby.

    I’d be sympathetic if you didn’t seem to be working on other projects while this one is still broken. If you are going to take money for this project, there should be ONE DAMN SETUP that works. Working firmware. A functional bootloader. Complete basic documentation.

    I’d be more thrilled to hear about your arduino-based TinyG, if the original TinyG worked correctly. It seems to me, the guy with three of your boards and a pile of stuff they destroyed, that you are farting around with new stuff while the people who already PAID YOU are dead by the side of the road.
