I have now 4-5 years dealing with 3D printing and my P1S is my forth 3d printer.
Let me show you the great printings I dis recently with my P1S:
and 2 quick recordings:
Looks like anytime the printing head needs to print a bridge, it ignores any geometry it has just printed - goes wherever it needs to go to position correctly for the bridge, but makes no delta Z displacements and simply destroy the print in process!!!
My old time 5% print failure has turned in a pathetic 50%+ failure!
The first recording is due to poor adhesion. That is not a slicers fault. That’s a you fault, at least on these printers. After 4-5 years I shouldn’t have to tell you to wash your bed.
The second is again, poor adheision. How is this the slicers fault. I fail to follow.
Edit.
From first glance that’s all poor adheision. At least with the details the videos showed.
Meant to edit my first post. Since this will be here regardless I’ll just leave it. MY FAULT
No, it is not poor adhesion. No problem up to the layer with bridge - then all the printed walls starts to move exactly when the printing head touch them. PLA with raft base and 75C for hotbed - just perfectly cleaned with isopropyl alcohol before the print should not move.
Colleagues trying to print my models:
“This failed twice for me at the same place (over 90%) on a P1S as it is printing the bridge of the large spool holder. The nozzle’s cover gets knocked loose and the print loses adhesion to the bed. Attempts to tape the print to the bed and restart result in more collisions with the print head.”
" even with glue on smooth plate. the nozzle seems touching the top pieces."
Yes, after 5 years I know to “wash my bed” and I know when it is my fault.
It is poor adheision.
You can see the model come off the plate. Most of your pictures are poor adhieson. You can say it isn’t, but it doesn’t look like anything else.
Enjoy tilting at windmills, peace.
75 on the bed, what are you printing with?
I never had any luck with a texture build plate and IPA. I could never get it clean enough.
If your not using 99.9% IPA your hurting yourself.
If this was me, I would wash with hot water and liquid soap to see if it gets better.
I have used 99.9% IPA for many years now and I managed to never hurt myself.
I am wandering if, in the first movie, from second 20 on, when the base of the part is clearly attached to the hotplate and the top of the part moves left and right, can we call this poor adhesion?
And curiously, I have “poor adhesion” only on two different models, repeated the print 5-10 times always with “poor adhesion” and failed prints. Same model printed 30 times without problems on a different printer.
Between these failed prints due to “poor adhesion”, I managed to print other complex models without any poor adhesion issue. So, it must be “poor adhesion”…
Whoa cowboy, cool your jets. You come asking for help and get all defensive when it’s given. If you disagree that’s cool, but coming off as a hothead isn’t.
Your print isn’t being hit, at least that I can see. It’s being printed and from the looks of it the filament is pulling a bit as it moves to the next spot. This happens on every print, you know this.
That tension is pulling your print, which isn’t staying stuck.
Happens with any tall (related to base) print and one like the spool that has multiple objects close together with small bases.
I’ve watched these everytime you reply, thinking I’m missing something. Look at the first video. The object starts moving vertically before you get to the bridge, then lets go.
Same in the second vid. Looks like one in the back is already leaning way before any bridges are started. The foreground has one on the left rocking, again before the bridge is started.
I don’t have a dog in this fight. If you ask for help then don’t get grumpy because you feel insulted. If I wanna insult you I’d do far better than blaming adheision.
Now, take a breath, can’t we all just get along?
Yes it is, in both videos.
The 1st vid you can clearly see the model rocking left to right.
The 2nd vid, the back corner lifts up.
Why ask for help if your not willing to listen…??
Tell you what. Where’s the file on makerworld.
If I can print it without it failing, then you will agree it’s not the slicer? If it doesn’t fail I’ll send it right to you to try.
I can slice in Studio or Orca.
I am really grateful for any idea - and the technical part in your last reply is valuable - I may have to think to what you said. But being told “in 5 years you should have learned to wash your bed” is less constructive.
Imho there is an issue with the implementation of the slicing software designed for a bed slinger printer (Prusa). At Prusa any movement is associated with a + delta Z for the printing head. At BL only the filament retractions get a - delta Z, any other printing heat movement keep the just printed Z. My impresion, like a few colleagues said - we have cases when the head hits the printed geometry. Or is poor adhesion 
You are 100% right, I apologize.
The most I’ve heard of the print head hitting the print is usually with grid or any infill that crosses itself.
In this case I really believe it’s tension pulling it. Hit that thing as you would to clean, then run a green scrubber over it. Make sure to do a bed level. As well if you’ve changed anything in the slicer reset to default to test, this way it’s easier to troubleshoot.
Thanks - I would be happy to learn that the problem is at bed adhesion.
Any model with the minimum number (10) of elements.
gimmie a min. I have a quick print to do and I’ll try it. About 30 min
You are right, like everybody else commenting here: it is bed adhesion - I am willing to listen . I just don’t understand why I am at the second model now that cannot be printed on my P1S. Why the vertical walls are so much displaced and pushed until the bed adhesion is lost?!
From the pic in your link, that it a layer shift.
Either the print head hit something, like infill or your printing too fast causing the same result.
I used Orca here - not having any other better idea… and I looked one hour to a perfectly printed model. Then in one minute all the vertical walls have been touched and moved all directions - but due to the very good bed adhesion the print managed to withstand the hits, just some bent walls… Post bridge printing everything was again OK.
I sliced in Studio, printing in PLA cause I’m too lazy to load ABS after just taking it out.
If you hear from me tonight then it went south. If it prints properly I’ll save the vid for in the morning. I’m printing on my smooth sheet which isn’t equal, but again, I just took it off and it’s all the way over there…
Thank you! I really appreciate it.
