    tinyGV9 is a development prototype that a few folks have for beta testing.
    It is not “on the market”.

    Depending on your development needs, you could emulate it with an Arduino DUE plas a Gshield or one of the 4 driver new Gshield-like boards coming on the market

    You can also contact the tinyG business team via

    – $defa=1 did reset all the setting (despite printing lots of “File not open”-messages)

    the defa=1 command resets tinyG to a compiled-in set of default parameters which are not likely useful for your machine.

    After defa=1, you need to re-enter your parameters.

    Send a $ or ? command from cutecom – if tinyG responds, the USB link is working.

    If problems continue, copy your $$ dump to a text file and post it to a cloud drive, post URL here

    Possible? Most likely, yes.
    The host(PC, could be tablet or even phone) is primarily to view messages and interact with command line interface, a debug port. I have seen some folks working to fashion a DRO using various Pi display shields.

    My initial guess would be that you need do nothing, aside from setting up your Pi so that your can run command line files from your host PC.
    I run linux, so that is trivial.
    Of course you will have to install UGS on the Pi.

    If you run Windows, you might need to research how to use it as a command line client for Pi.

    Post a copy of your parameter set ($$) to a cloud drive and provide a URL here, along with the specific G0 command you are trying

    You will find the secret decoder ring for status messages here:

    I’ll say, in theory, yes it could be implemented..

    You would need to develop a sketch for the arduino that would handle the serial I/O to the USB port which you connect to tinyG.
    I have not seen anyone trying, but that does not mean it has not been implemented.

    If small is your goal, a RaspbPi 2 might be easier to implement – since it is running Linux you could port something like UGS over to the Pi.

    Have fun

    I saw your note at

    Time on really has nothing to do with it – a batch was programmed to be overly sensitive to input voltage droop, needs to be reflashed (low level reflash)

    You will hear from Riley.

    Have access to an Atmel device Programmer/ICE ?
    You can do it yourself, too.

    Here is a link with status codes enumerated:

    Is this really an error (e.g. half way thru the job) or a ‘warning’ at end of job?
    Very (very) few folks watch warnings coming back unless something really bad happens (such as stop in middle of job).

    You have a big machine – Y range 1500 mm.
    Set a (0,0) near the mechanical Y0.
    Do a
    G1 Y1000 F800
    moderate speed long move,
    measure the actual distance with a good meter stick.
    The adjust $_tr on your Y motors by *(distance_measured/1000).

    Using your example above , you would reset $tr to 60* (19.5/20)=58.5.
    Repeat this until you are satisfied with accuracy.
    Then use the same $tr for Xaxis, retest there.

    What you just posted looks same as three hours agoo, all $trs = 1.25mm

    i may have uploaded the wrong settings. the belt is a GT3 with a 25 tooth gear. The machine is a 750X1500. X=750 and Y=1500. If i am at front left corner the X would be my horizontal axis, correct? I am going to see if i can attach a picture in another post. If i can attach the picture I am considering the Y the longest axis.

    This is a difficult subject. For ShapeOko folks, 0,0 is typically the “lower left” corner and for Ox folks it is normally the “upper right”, but then you will ask “relative to what” and I will say, I don’t know because the machines are more or less symmetrical.

    I suggest zero your machine in the middle, then see if +X and +Y makes sense.

    For most folks, Y is the longer axis, but even that is not really fixed.

    Typically X has one stepper, Y has two, if that helps.

    Yes, I now have it.

    When I look in that file on Gdrive, I don’t see what you describe above.

    I see
    $1tr=1.25
    $2tr=1.25
    $4tr=1.25

    Are you sure you posted the current settings?

    If so
    set
    $1tr-60
    $2tr=60
    $4tr=60
    $xtm=x size of your machine (1500?)
    $ytm=y size of your machine (1500?)

    Soft limits will still not be in effect, but have $xtn=$xtm=0 might shut off the axis.

    You Gdrvie folder or file needs to be shared.
    You will receive an email from Google

    Hmm, sounds like a parameter issue, unfortunately this new Onedrive link does not work, sends me to Microsoft trying to sign me up.

    See if you can refresh the link
