    I designed a stool in Fusion 360. I’m attempting to cut out the top.

    I used 2 2D Contour’s. The first for the middle slot to mount the legs.
    The second for the outside edge to actually cut it out.

    It appears that 3/4 of the way through the first cut the router just
    stops. I’ve tried using the LCD Smart controller and repetier. In repetier
    it says “Job Killed” or something like that. With the controller, It almost
    seems to reset.

    I’ve had this happen with things I’ve made with EstlCam too.

    Any sort of pointing me in the right direction is appreciated.

    I tried to post the .f3d file and the gcode but its telling me I cant
    for security reasons.

    #27109

    Post it in a .zip file

    -MPCNC Version C
    -RC7 Firmware
    -Full Graphic LCD Smart Controller
    -X and Y stepper voltages set to .68v and z set to .7v

    Gcode and .f3d file are in the .zip file.

    What happens to an MPCNC if your power supply is inadequate? If at any point
    the MPCNC tries to draw more current then allowed by the supply, what happens?
    I’m using a 4 Amp power supply and have had things cut out before
    but most things fail to cut. It doesn’t seem to matter if I use EstlCam or
    Fusion 360 to create the code or If I use Repetier Plugged into the stack or
    just the smart controller to execute the code. Now with that said, I can’t
    guarantee that my tool paths/code is right to begin with.

    I watched my smart controller/ramps board this time. The ramps board literally shuts off and turns back on, same thing with the controller.

    Did it shut off in the exact same spot? That would indicate a gcode related error. If it was a different place we need to look elsewhere.

    What are you using for your rapid speeds, that seems to be the issue most people are having these days (thank goodness).

    Ryan, where would I find my rapid speed in fusion? What would it be labeled?

    It appears to be the same spot. I’m running it again to be certain.

    You don’t think this is thermal shutdown, do you?

    You haven’t given any information to make any guesses on thermal issues but I doubt it they do not shut down the system they just stop moving the drivers.

    In fusion you rapids are set in you post processor and in your tool settings. How fast are you asking it to move at any given time. Cut speeds, plunge speeds, retract speeds, rapids. If you repeatedly ask it to move too fast the processor will reset the whole system. We aren’t using RC8 because it is a little more susceptible to this at the moment, but it can happen in RC7 if you are wayyyy off.

    Ran it again.

    On cut 1 of 2 (the circle) it makes multiple passes (maybe 4). Raises the tool and drops it back down to then perform another pass and stops. When it stops, the red led on my ramps board shuts off and the controller starts the load screen (Vicious logo > Marlin firmware screen> controller interface)

    I’m using the post process file for fusion 360 by the way.

    Is it stopping in the exact same place, I don’t know where it stopped before?

    You speeds look okay.

    Hardware, are you using my stuff or your own? If it’s your own spare no details.

    Well if it is the exact same spot, try a new gcode.

    Are your drivers set at .7v or less or if they are higher do you have active cooling on them?

    I have a 40mm high output fan on the side of the stack. All drivers are set at.7v or lower.

    Multiple gcode made by fusion and estlcam stop mid cut.

    okay, then run the gcode with your spindle off.

    When I reattempted it a few minutes ago. I brought the z point high before starting and ran it with the spindle off.. same thing.

    Could 4 amps of power not be enough and that’s causing the ramps board to restart?

    #27159

    If it is a crappy 4A, and not really 4A, like most cheap power supplies are. It should be enough but I recommend at least 5A in the instructions. It took a long time for me t find a reputable power supply that isn’t severely over spec’d.

    Does your power brick get really hot?

    Does my test gcode run fine and just not your gcode?

    Power supply is cold. Where do I find your gcode? The one from your lcd controller?

    I’m starving, headed out to lunch be back in an hour or so.

    How was lunch?

    I ran your left.gcode. ran right through at 15my and 41s.

    Would it be too much to ask for you to run mine and see what happens?

    The error happens around the 8 minute mark.

    I took my little tiny fpv quad out for the first time on the lunch break…..that is a new experience for sure!

    Ha, I didn’t think to run your code…duh, brain fart. I’ll load it up.

    This might sound stupid.. but when I run your code, the red led on my ramps doesn’t turn on.. but when I run mine, it does.

    Apparently that’s LED3 and its associated with a fan. Your gcode did not turn the fan on, mine however does. On my smart controller, it says the fan is at 100% when I run my code. Nothing for yours.

    The new post processor does not have the fan on by defualt, you should upgrade we all made changes too it the new ones are much better. v9 and v10.

    So I think that is the issue you are using v6 of the postprocessor the rapids are built in and way too high.

    So v10 is current?

    #27173

    v10 is, but I have only tested v9 and am not 100% sure what was changed in v10

    I’ll use v9 then. Thanks for helping me out with this Ryan. I’ll have to
    put it to the test tomorrow just to be sure but it makes sense as to why
    your .gcode worked and mine was useless.

    I just wonder what aspect of this made the ramps board restart.

    It is the Z axis rapid movements speeds, to many steps/second for our arduino processor. The previous post processors did not take this in to account.
