Please help in solving below issue. This is the 3th or the 4th fail print(almost used one complete roll). All the time is start to give error at same chanfer hole. I wander if is a problem with printer or with my model?
I will try now to print with normal holes. Printer is a f
Flashforge Finder. The error that I got this time was error file.
Blow Fan the Nozzle cold only on this Position? Then no Filament is extruded.
Any way we could get a look at the model? (So long as it’s not under NDA, etc)
Looking at the pic, I don’t see any infill inside that gap (I’m presuming this is a solid box?): If that’s true, it means you’re printing that internal ledge over empty space, and over time that bridge is probably failing. Either put some infill in there to support that internal overhang, or change the model so that isn’t a 90 deg corner, but a 45 deg-ish chamfer.
Here is the model. Where is marked with red is the point where I always get the error. I went to netfab, it is saying that the model is fixed, but I can’t see any difference from old one.

Looks like a layer shift to me. Something at that point/height in the model is apparently triggering this.
If you sink your model into the bed in the slicer and start printing just below the hole does it work? If not then I would guess it is likely the model feature in combination with your print settings.
You can try slowing down the print at that point and see if you can get past it.
@Jeff_Parish : Agreed. Looking at a pic of the model, the whole print seems shifted for a section, which either could be caused by mechanics, or a bad slice. I presume you slicer lets you preview the results, and it doesn’t look like this?
@Pop_Gheorghe Curious. What does it look like on the opposite side? Is it shifted out?
@Eric_Pavey @Jeff_Parish from the marked hole it shifts out. 3 times at the same poin with a diference of 1-2 mm. And yes, also on the other side is shifted.
@Pop_Gheorghe , 2 things. A) Check pulleys, make sure set screws are tightened down. B) If your drivers have heatsinks, put a little fan near them and try again - you might be reaching a point where they thermally shut off…specifically the X motor.
Additionally, reprint with the “netfabb fixed” version - your software might not be showing triangle faces properly.
Finally I managed to solve the issue. At least this is what I think/hope.
It seems the problem was with the wiring to the X-axis motor. As you can see from below picture the wires were repeatedly hitting the frame of the printer and got damaged. I managed to observe this by touching the wires and hearing a strange sound from the stepper. After cutting the clips and replacing the wire it seems the problem disappeared. Also this issue was happening only on large prints. Small ones were getting ok.
