That's one thing I thought at first, but things changed when I did the (partial) reset.
Thats strange, I'm having what looks like the same issue after months of no problem at all.
I've not changed any settings - not updated firmware recently either.
Now every print I try to do stops extruding after a few minutes - usually on the first layer - looks exactly like yours.
My printer is a S3 so I also tried printing with extruder 2 in case there was an issue with extruder 1 or with feeder 1. this made no difference and the printer stops feeding PLA after a few minutes.
It can't be a bed levelling issue or I would still see PLA being extruded from the nozel.
could it be a temperature issue? not sure what to check next.
Just finished another test print and it seems to be working again now.
Only thing I did was a factory reset. so maybe it was that. fingers crossed for a larger print overnight.
Meeple, that failed print looks extremely close to one of mine.
Here's an update.
As a sanity check, this afternoon I tried printing an extremely trivial item, a thin flat plastic washer for the same project, which I was printing several-up on the Prusa. This is 10mm in diameter and .4mm thick.
The first few came out perfect. However, as I printed more of them, they got rougher and poorer with each print.
I then shut the machine off, powered it down and let it thoroughly drain. Powered it back up and printed a single washer which came out perfect. Rinse-repeat. Power down, wait, power up, print washer, perfect.
Then I powered it down, let it drain, and printed that vertical post (which failed miserably this morning), and it came out perfect. There were no changes other than power cycles between the failed vertical post pictured above and the recent successful one.
It's now powered down and draining and I'm about to walk over to it, power it back up, and try the flat piece to see if it prints ok right after a power-up.
Film at 11.
Mine has failed again after I got the successful print yesterday.
i will try a power cycle and see what that does. (obviously thats one of the things that the Factory reset did earlier which begs the question did the factory reset do anything or was it the power cycle that did the trick?)
I've tested with 2 different print heads, bowden tubes and filfment feeder units with exactly the same results, so I gues this is something further up the chain like maybe the controller? maybe the controller is causing the print heads to lose heat after the job has been running for a few minutes and that causes the filament to stop feeding?
My optimism was a bit premature. The flat piece failed, almost exactly like yours and my previous one.
However, power-down, wait, turn on, print the vertical post, came out perfect.
This is not making sense.
I'm wondering if this may be software related, and it might be a good idea to version the box as a next step. I'm currently running 6.5.2, what are you running?
I'm running an S3 with firmware v 5.2.11
there is a newer version 5.3 and i'm going to upgrade but I'm not holding out any hope that it will fix anything.
in other news my print core 2 now has filament stuck in it that just won't pull out. 😞 so thats now out of action and I'm back to print core 1
Hey @jsw,
This looks like a leveling issue to me aswell.
There is a diagnostic test that you can do to check if there is something wrong with your sensor.

If the noise level number is higher than 8, something is broken and you can contact support to help resolve it.

Hope this helps 😊

If it was a bed levelling issue I would expect to see lots of speghetti filament as the remainder of the print gets extruded ?
(there's no spaghetti on my prints not sure about JSW)
Following my upgrade to the latest firmware 5.3 I have now completed 2 successful prints without having to reboot.
Fingers crossed I will be able to complete the largest print overnight.
I ran the bed leveling test and it passed. Ditto with the sensor switch test.
I'm currently downloading 7.0.3 and will version the box as a next step.
If the issue persists I'll probably phone or write Dynamism support tomorrow and I'm sure one of the first things they will ask is if it is running current firmware.
Another update, I just updated to 7.0.3 and there was a yellow (!) warning suggesting to update to 7.1.3 as it fixes a bed leveling issue observed in the field. Downloading 7.1.3 now.
Hope your FW fixes the issue then.
My printer seems to be behaving at the moment. the overnight print completed successfully.
I will keep printing but that was a wierd issue.
Have you looked at the nozzles themselves? You using an AA0.4 or AA0.8?
Try cleaning them and trying again, if it fails again, I'd look at the feeders....
Failing all of these and the print glass is level, next would be to look at the guide bars above the print head.
I have used three different known-good AA .4 print heads and one known-good AA.25. One of the .4 ones was cold-pulled and needled to be sure.
Also, this is currently losing extrusion, not printing in the air or printing squished against the build plate.
One of the areas where the extrusion is poor on the flat piece is dead-center, where the successful print of the post occurs.

I think it still could be the nozzles, as the printer is printing the "walls" ok but struggling on the "in-fill". Strange....
Edited by CarbonAnd I just did a good cold pull on one of the other AAs, same thing, loses extrusion midway during the first layer.
I'm going to contact Dynamism support on this, as I am totally stumped.
@jsw I am sorry to read you are having troubles printing. I can imagine this must feel quite frustrating. It is hard to diagnose the problem just by looking the pictures. Could you share the logs, in combination with a picture of the failed print.
Best regards,
Jos
Thanks, which logs, specifically (IIRC, there are many files) do you want?
If you save the logs to a usb drive from the diagnostics menu you will end up with a zip file, that zip file contains all the logs I need :)

Looks like a bed leveling issue to me, my suggestion would be to try re-leveling the bed
Good luck
You could also try moving the part to a different place on the bed
