    hello all,
    just joined, hope to meet some great people, get/share ideas

    not sure if this is correct spot for this post but...

    i have my unit working but still in calibrating and setup stage
    when i print larger prints (full work table size) the program stops at a certain point and does not finish.
    it almost seems like the code pauses and does not complete. smaller projects have no issues.
    i am using universal gcode sender. i had .9j and upgraded to 1.1 thinking that was the issue. the same thing
    i use inkscape, gimp, and a few other but mainly inkscape to produce outlines with J-Tech

    is there any ideas what i need to check???

    Is the code actually stopping, ie do you see it stop? Or, do you leave and come back and it has stopped? When I was using the DRV8825 drivers and was doing a couple larger projects, the drivers occasionally overheated and I would come back and see the code still being sent. However, the CNC Router was just sitting in one spot. Once things cooled down, I was able to get everything working again. This only happened a couple times, but it was the main reason I upgraded to the DQ542MA drivers.

    If you look at the code in a simulator, is it complete?

    also check that your Arduino is not a clone with a CH430 chip, they tend to lose the plot with long sets of data. A real Arduino with a 16u2 chip that you have upgraded is best.
    to update, go to Arduino - DFUProgramming8U2

    but I agree with Craig, probably the drivers overheating....

    The code does stop streaming on screen.
    I also made sure my screensaver,sleep and hibernate are turned off on laptop.
    The motors and drivers are not hot enough to cause thermal issues.
    I have the current adjusted, just about quiet but slight squeal on motors.
    My Arduino is an original, logo on board.

    and is it updated? the original USB code has bugs that cause streaming to stop.

    I am using GRBL 1.1
    Used Xloader to flash 328
    Used USG 1.09 and now the newest version
    I plan on trying another program, 3DPburner, and see what happens

    Does it stop after the same amount of time, and or, at the same place? Does it seem completely random?
    Does initially sound like a heat problem though.

    I had a similar issue with my laser engraver. Started the project over and stopped at the same location each time. After looking several times at the code (had to manually make adjusts for the laser), I final found I had a line of code that must have confused the controller. once I corrected the code, everything worked good.
