    Manually moving the gantry on a belt CNC (e.g. Shapeoko) will cause tinyG lights to blink, etc, due to back drive, but no one has reported a death such as this.

    But, it would not surprise me that constant drive such as you had, for a period of time, could likely have exceeded the tinyG input voltage .

    I suggest you read the 8818 product data sheet.
    It is a heat slug pachage, soldered to the PCB.
    You are going to need a lot of heat and 3 or four hands (or good fixturing)

    Good luck

    One additional item – UGS works MUCH better with tinyG flow control set to $ex=2, RTS/CTS. You have to use CoolTerm to do that.

    The process of sending a Gcode file, and the Visualizer, seems to work OK.
    There are a lot of functions that don’t work or don’t work completely.

    I could find no way to do Setup from within UGS (such as set parameters, display parameters with $, $$, etc.)

    So you have to use CoolTerm or similar for management functions.
    UGS does seem to send Gcode with progress trace capability

    By the way, most all example posted by Synthetos will be for machines wired X-Y-Yr-Z. You have your machine Z-Y-Yr-X.

    It will work that way, but your will always have to be mindful when reading example parameter sets, etc.

    For now set $sl=0 until everything up and running

    Looks like you have GT3 belts?

    Z axis, $1tr=8000.00 ??
    X axis $4tr=60000.00 ??

    suggest use $_pm=2 on all 4 motors

    I think $1tr and $4tr are your biggest impediments to progress

    I just brought up UGS-daily build on Win10 with java 8 installed.
    Connects to my tinyGV8.
    I can jog, see lights flash on tinyG, position status updates,

    UGS-daily also running on Linux running openJDK 1.8.0, similar results.

    But commands like $ or $$ don’t display anything.
    Not sure why

    I also tried sending an old Gcode file.
    The Gcode Visualizer running, seems to be progressing very slowly (relative to Chilipeppr), but Visualizer tracking progress.
    Interestingly, the Machine Status window not tracking X Y Z position.

    I don’t have motors actually connected to this tinyG, I am just watching the Motor LEDs flash.

    Still fiddling

    I had never tried UGS, have seen comments that “it” works.

    You are trying version 1.0.9.
    I just tried it on Linux, got about as far as you did.

    What host OS and Java version on your system?

    I have no great suggestions , perhaps another user swill stop by

    I can see the picture.

    What Software am I looking at – don’t recognize it?

    Since you mention com3, Windows assumed.
    SPJS running on windows as well?
    A helpful first step would be to create a $$ parameter dump in the Serial console, copy and paste results into a text file, post the text file to a cloud drive (Gdrive, Dropbox, etc) and post a link (URL) to it here.

    What OS are you running? Windows?

    Have you reviewed

    and other Wiki items?

    GrblController – No, as far as I know.
    UGS – yes
    Also CoolTerm for basic tinyGV8 control and setup.

    Jeromy
    Thanks for your experience write-up. Not many folks have programmers so I don’t suggest it by default.

    You are running windows, I presume.
    Running SPJS on the same machine?
    I have successfully run the tinyg.hex uploader from CP/SPJS running on Windows.
    Are you running SPJS ver 1.86? If not(meaning version <1.86), you have to manually disconnect from tinyG in the Serial port widget before running the updater. As of SPJS 1.86, it automagically disconnects (frees up) the serial port for the uploader, which is really a sub-process spawned by the Widget.

    Report your issue at

    Its not really a good idea to stay behind in FW unless you have a very repetitive job that just works, and the fuse setting issue (if that is your problem) could affect any FW build.

    Hmmm, not much difference between hitting the reset button (or power cycling) and sitting over night, unless your tinyG was overheating.

    But what you describe does not sound like motor driver shutdown due to overheating.

    Do you have a fan for tinyG?

    If problems return, try generating your Gcode without ARCs(replacing them with short straight moves). Some folks have had issues with Arcs in the X-Z or Y-Z direction. When you mentioned helix movement, I sort of expected to hear that.

    Good luck

    For starters, I hope you have reviewed the tinyG wiki, especially

    with focus on Gcode commands supported and not yet supported.

    It would be helpful if you could post to a cloud drive (Dropbox, Gdrive, etc) you parameter set (a $$ dump) and the problematic Gcode for a look by the devs.
    Post a link here.

    Also, what OS are you using to interface with tinyG, and what program to send Gcode (CoolTerm, UGS, Chilipeppr, etc)?

    Give this a read:

    Since you are in standard mode, I believe your $4tr should be 360, unless you have a gear box on the motor. And then you will have to enter moves in degrees, not mm.

    If you want tinyG to figure out the degrees, you probably have to use $4aam=3, radius mode, and properly configure.

    If you are not using homing, then set $asn=0.
