I just got my P1P. I am using prusament PLA filament. I started printing some vision enclosure parts. Sadly, about 50% of the prints fail heavily. The printer, at some point, starts crashing into the print objects and smashes them off the print bed.
For me, it looks like the printer stopped moving at some point and some blob was created, leading to a crash after it moves again. But I am not sure. I have attached images of the last two failed prints.
I don’t see what is wrong here. I am coming from a Prusa i3 and I never had such problems.
I am using the normal print speed (100%) and the generic PLA profile, even though this looks more like a mechanical failure or so. I print the objects one by one. No special settings. Firmware is 01.02.03.00 (newest)
So far, my experience with this printer has been very underwhelming. These are pretty simple parts. I have no bed adhesion problems, there are no big overhangs.
These pieces should really be printed with as many perimeters necessary to make them solid. You’ve got minimal infill and the print head will be moving very quickly which will cause the print to wobble at the top.
Actually, I have found another issue on my prints, which could also lead to the crashes. For some reason, the slicer adds like “half height” layers in between my print. I checked one of my failed prints and it is exactly at the position of one of these that the print fails.
I checked the same model in prusa slicer and these extra layers are not generated there.
I am using ALL standard settings 0.20mm.
These extra layers seem to exist of only one inner wall, and are then “cought up” by 2 layers which only print external walls, but one less than expected.
It’s not a “number of perimeters” problem. The amount of extra movement from only having 2 perimeters (the default option) as opposed to 3 is absolutely orders of magnitude smaller than what is going on with the printer chassis, belts and bed. The printer bed moves up and down rapidly and the head moves incredibly fast, I was awestruck by this printer, until mine crashed halfway through a print after two weeks.
What exactly do you mean by ’ the slicer adds like “half height” layers in between my print.’ How do you know there is an extra layer and how do you know it is half the height?
What do you mean by half the height? Half the layer height =0.1mm ? Or half the height of the model? And how do you know this is a bug, and not some expected behaviour. (I mean we know the print head is not supposed to crash, but why do you attribute it to the slicer?}
Have you sifted through the millions of lines of G-code to find this?
For me this happened with a tall(ish) (100mm high and only 20mm wide base) print but I did put extra support on the sides. See picture.
It’s possible that it is a bed adhesion problem.
Your print is also tall.
The excessive vibrations probably mount up over time and cause adhesion to fail bit by bit. Then when the model tilts you get a massive crash.
A brim helps, but you already have one, and I have support all around the base of my print.
This is not what I expect from a $1000 printer.
I don’t do the vibration tests before every print. Maybe I should.
I will say the print you are trying to do, and to some degree mine, is certainly a bit unsuited to 3D printing: long and tall, with minimum contact on the bed. We could consider re-orienting (not ideal because of all the waste support that would be required). Or redesigning to make the part more 3D printer friendly.
These are pretty simple parts. I have no bed adhesion problems, there are no big overhangs.
