Object got knocked over?

@OwenD said in Object got knocked over?:
Well, all of my stinging and extrusion tests came out good.
How smooth is the first layer?
The first layer was very flat, even, smooth and looked very good to me. ( I have no picture at the moment and the printer is busy at the moment.)
-
Here are two pictures from the first layer:
-
That looks a bit over extruded but only on that one corner, which could mean the bed isn't very level or flat. Have you done a G29 to map out the bed surface?
-
Which corner do you mean?
-
The back right one that looks rough as if the nozzle were too close.
-
Well... yes, maybe. But why should have that impact at a part at 72mm height than? II mean so hard that the nozzle knocked over the part? I have to mention that my temp tower was much smaller than that first layer.
-
Well I didn't see a photo of the failed print, just the first layer and that's what I noticed.
Over a long print a small amount of over extrusion can result in quite a bit.
I assume you've been through this calibration?

Oh yes... I did.. I learned that drill with my CR10 already.
Her the bottom of the knocked over print:
Her the top:

Well it does look like it got stuck at the blob there.
Was this being printed as a temperature tower with varying temps?
-
Yes it was
-
What temp did it fail on?
-
Can you post your full config.g?
Did you happen to get a heater fault message?

Can you test if you can reliably extrude at 195c? That might be too cold and it clogged?
-
Good point.. I will finish the current print first. ... do you expect that PLA will fail already at 195?
-
Depends on the PLA. Depends on how much volume you're trying to flow. Depends on how accurate your thermistor values are.
You could do a volumetric flow rate calibration at that temp to see if your speed height width combination was more than the hotend could handle at that temp.
Did you try to print it again?
-
@Chriss Just try using an extrusion multiplier of 95%. Parts are surprisingly very tolerant of under extrusion, but very intolerant of over extrusion.
-

@Chriss I didn't look at the pictures earlier. Now that I have, I can see the problem - I've had exactly the same thing myself in the past. It's the overhang curling up at the edges. Increase the part cooling or re-arrange the ducting.
