I got my P1P a few weeks ago and it worked great up until the other day when the camera and LED upgrade came in. I installed the camera and printed the shell for the LED no problem. Then when I ran a print in order to test out the camera, the print failed and I have yet to have a successful print since.
When I discovered the failed print, the front of the print head had fallen off but did not get damaged that I could see. I cleaned it up and tried another simpler print, but it seems like now the filiment doesn’t stick to the bed. I tried cleaning it with IPA and when that didn’t work detergent but no luck. I believe it’s just coincidence that I installed the camera and this started because I did try disconnecting the LED and camera with no change. I searched the lead screws and entire chamber for debris and found nothing.
I’ve noticed globing on the purge strip. I tried to run the flow calibration, but the filament doesn’t stick to the bed and gets balled up. I’m thinking maybe there’s too much flow, but can’t seem to find where to make that adjustment.
I’m also beginning to wonder if something is going on with the bed. Maybe to hot or not hot enough, but again, not sure where I can make these adjustments in Bambu Studio. Maybe the Z offset.
I also changed out the nozzle with a hardened steel one to see if something happened to the nozzle but no change.
I thought I saw a post with the same issue but can’t seem to find it now.
*** Finally got an error code : “HMS_WARN_0500_0d00_0002_0001” When I looked it up it said something about environmental vibration and possibly something on the nozzle, but I swapped out the nozzle with a brand new one. I haven’t seen the error since.
Did you use the same fillament before and after?
Yes. I did try changing it out at one point, but no luck, so I went back to the Bambu PLA that came with the printer
Here is a print failing. It’s just an old calibration print from my Ender I used so I could see where it’s not sticking.
This is my start up right before that print in case something is happening that’s not supposed to be.
Your bed leveling seems odd. Looks way too quick. Also, your first layer isn’t going down slow. Did you modify the start and end Gcode? Are you using a modified slicer? Things just don’t seem like they should. Also the way the first layer failed, the printer thinks the bed is at different heights than it is.
You have clearly changed Gcode or other settings because first layer should NOT go that fast.
Is your part flat on the bed? Looks like the first few lines stick pretty well and are done at low speed and the lines that don’t stick are much faster, indicating the printer is doing the 2nd layer?
So check if your models first layer is completely on the bed in your slicer.
Also slowing down your first layer a lot might help.
That was at a full factory reset and every print I send fails like that. Not a modified slicer. The print in the video is a test print for leveling my Ender. It doesn’t appear to have anything more than a first layer. I agree and I believe something is off with the bed. I don’t even know how to change the gcode with this printer. Someone in another thread suggested to someone else to add something to the end of the gcode to change the Z offset but I couldn’t figure out how so I just didn’t try. I am fairly new to this.
I did try slowing the first layer at one point in the slicer, it did the same thing just slower. Leads me to the bed again. I have also been testing with the Benchy on the SD card that came with the unit which before that first fail, printed flawlessly in like 25 minutes.
So a benchy from internal memory is still printing good?
Try a larger print from the internal memory then. Like for instance the scraper. If that prints good, it is something in your slicer for sure.
Maybe de-install your slicer and install cleanly again.
Also to avoid another factor (it happened to me already once, so I know what I talk about) - printer & printbed as well as filament is correctly choosen in the slicer?
Double checked slicer settings, PEI plate selected, P1P selected, and Bambu Lab Basic PLA selected. I just attempted the Benchy straight from the SD card again with no luck.
Going to try one of the parts from the pegboard shell, maybe I’ll get lucky…
can u share your sliced file please? Slice → export as file…
…and what speed do you use? 150%? it looks much to fast
So how is that purge line sticking? Is that on there good? Or also loose?
Interesting… it seems to be printing the shell just fine. It’s not perfect like the first one I printed was, but this I can deal with.
Still don’t understand why it wouldn’t print the benchy straight from the SD card unless it’s just too fast, but I can’t seem to be able to change the speed. I can’t even tell what speed it’s set at. When I try to on the pannel, it highlights the little rocket with the 100% next to it and I can see “ludacris, sport, silent” but can’t select any of them. In the slicer, it changes, but gets stuck on the screen and doesn’t actually do anything.
I had taken a pic of the settings in the slicer before I loaded the pegboard project and the only difference I see is that before, under “Filament” it shows AMS settings, after it doesn’t.
The Benchy file is the one that came on the SD card with the printer. After this print attempt, I will pull the card out and share it. It says 100% for speed but I can’t seem to adjust it. I never even put the file into the slicer.
The purge line is sticking good but at the ends it’s globing and that’s the only spot it seems not to be sticking as well.
Thank you so much for your help. This has been super frustrating and it means a lot to me to have some help.
Doesn’t seem like the factory code on those examples (at least from my experiences). Did you change it after the example? Your bed leveling started from the middle of the bed and only tapped down in 5 spots. Your setup code ran for much shorter than is normal. People complain because it takes 5-7 mins to finish and yours was done in less than 2 mins from the wipe.
On modifying the offset, I can’t see a good reason to touch the Z offset, because the printer uses load cells to figure out where the bed is. That means it knows with a 100% certainty what the Z Offset should be all by itself. Adding any offset would make it do what its doing, but immediately, not during the middle of the first layer.
But if you say you factory reset everything and nothing prints now, let’s try something simple. First clean your PEI plate with alcohol if you have some but something like Windex will do in a pinch. Try not to touch the surface area of the plate because your hands oils can stop the adhesion if there is enough of it. Download a calibration cube or make a 10mm by 10mm cube and slice it. Turn off any ludicrous/sport speeds modes and print the model. It should print very cleanly and still relatively quickly. If it doesn’t you may need to open a ticket with Bambu.
The benchy you posted looks like it purely an adhesion issue. If true the cleaning of the plate should fix that. I thought it was odd the first layer went down super fast, but I’ve never run the SD card’s benchy so that might be normal.
It doesn’t take much to bend the nozzle. A hit strong enough to knock the cover off might also bend the nozzle. A bent nozzle will lead to all kinds of issues. Prints won’t stick. Calibration lines won’t stick. The purge line at the back can end up off the bed.
Look at the nozzle straight on from the front and again from the side. Most of the time, the bend is large enough that you can see it without removing the hot end but you may have to remove the hot end to see it. You can leave the 3 connectors plugged in if you are very careful. Don’t tug on the wires. The pcb mounted half of the plug is surface mount, you can rip it off the board if you pull hard enough.
Thank you very much for the reply. I’m at work now and will try this when I get home or tomorrow morning.
Yesterday I had cleaned the plate with Alcohol and tried the Benchy, no luck. Tried cleaning with detergent, no luck. I even went and ordered a second plate but haven’t got it yet. I will try again though just to be sure.
I did get the pegboard shell part to print successfully. I figured that would be a good thing to try since it’s a grid and if the bed was off somewhere, I should be able to see where.

That actually makes a lot of sense, though I had a hardened nozzle/hotend assembly I tossed in yesterday and it didn’t change anything. But I will look at the one I pulled out and the one I put in. I think I have 2 more brand new nozzles I can try if that is the case.
I actually found the video from that failed print on the SD card and it doesn’t appear to be that bad of a hit. It mostly it pushed around a pile a spaghetti until the front fell off.
I will check this. Thank you for the input!!
