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.
-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.
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.
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)

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?
