This morning, my P1S was dead in the water. It printed well all day yesterday. It had begun to print when I stopped it after realizing I had sliced the wrong model.
After restarting it, I got repeated errors saying the auto bed leveling had failed. I tried the calibration routine a few times and it too failed in the auto bed leveling sequence and one time because of some kind of problem with the z-axis (the error disappeared before I could write it down.).
I was leery about using the calibration program but didn’t know what else to do. On the third try, it finally passed and I’m back to printing. If anyone has any idea of what caused my breakdown, I’d love to hear about it.
If you’ve never used the cal program before, there are three sub-programs to choose from. The first two take several minutes, but the third one, the motor noise sequence, took forever. Next time I use the cal program, I’ll unselect that one.> When asking for help, please provide as much information as possible about your inquiry.
Including pictures and detailed information about the print speeds, filament type and settings used will help get the appropriate solutions.
I know this is going to sound far fetched but it’s happened to me more than once. A squiggle of purged filament didn’t go in the chute but instead landed where the platform attaches to the back lead screw. I’m guessing it bound the screw from turning because I don’t think there is any sort of sensor back there. After I pulled it off everything went back to normal. Could this have happened and it eventually fell off on its own while you were trying to run the calibrations?
I had the same thing happen to me as Mcgee except the little turd was wedged up in the front left corner where the cutter is actuated. the sensor was being blocked causing the head to grind and unable to cut. Spent forever trouble shooting and replacing lots of things before i found the little filament turd.
OP get a bright flash light and thoroughly inspect for purge turds!
That sounds like exactly what happened! I have seen some poop fail to hit the chute but I got them out of the way before anything happened. I’ll definitely be on the look out for that in the future. Thanks a lot!
Thank you so much. That’s exactly what I’ll do.
In the future, I’ll make sure I see a turd come out of the chute with each print. I guess there’s a little room here for Bambu to do some product improvement.
I have this rubbish problem as well and find it VERY frustrating.
The machine SHOULD keep the inside clean but it DOES NOT.
One thing is all the nonsense moves on the P1’s that only make sense on a X1.
But I keep seeing how filament changes, purging and cleaning routines just fail.
The poop flies everywhere, strands and blobs of filament as well.
Only too often they end in bad spots and cause issues later on.
Whenever the nozzles leaks a bit before reaching the disposal area all the flushed stuff just land inside the build chamber.
Whatever mishap happened during purging and such often results in the wiper tossing things all over the place.
Don’t know about you but considering the high price and how strong all this advertised I was expecting better…
I was wondering about that myself. If you’re listening Bambu Lab, it would be nice to know if there’s something in the configuration options that would reduce some of these moves without losing important checks. Takes a lot of time and prematurely wears out the machines. Everytime I think it’s ready to print, it starts another routine of checking.
You can turn off bed levelling in the slicer. The rest of it, the gcode is well commented, maybe a python or other script to automatically strip out the unwanted code, e.g. the unnecessary pooping/nozzle wiping if filament unchanged (if you’re not probing). Not sure if the whole start/end gcode can be rewritten.
That’s a good idea. My clunky old Ender3s would print for days without a re-leveling. I bet these Bambus would too. I may look at deleting that and just run that bit maybe once every other day. Thanks
There is a guy who worked quite hard to provide working, custom start end end g-code to get rid of all the nonsense and wasted time.
But unless I am mistaken this only works properly using Orca.
Personally I find it rather insulting to be charge this much for a P1 model if Bamabu can’t even be bothered to provide a PROPER firmware for them that is free of the nonsense that just work work…
No lidar, no bed recognition, not need to check this and that if the hardware isn’t even present.
But it is FAR easier to just disable the non working things in a firmware than to remove them for good.
So instead of removing all the ■■■■Bambu went the quick and dirt cheap way and just flicked a few switches so the missing hardware won’t cause an error during machine operations.
I would even be able to understand this nonsense if X1 users would get the option to disable these hardware components.
Like when something is faulty and they have to wait for a replacement part to arrive.
But unless I am badly mistaken the X1 can’t even be switched into P1 mode ROFL
The thing that really stinks and makes me angry is the total lack of meaningful response from the support.
There is plenty of topic about the issue, not just in the forum but elsewhere and on Reddit as well.
Tells you a lot about the quality of their support if you get to hear that there are no issues and your firmware is just doing what is supposed to do…
Wow! You said a lot! I was born in 1945, so I grew up in a world where you took broken things back where you bought them, or, you called them and worked it out that way. Nowadays, if something breaks, you’re at the mercy of the internet or some kind of bot support. But I knew that going in. By now I’ve been there dozens if not hundreds of times with various electronic products. I just couldn’t resist the possibility that I might actually get some real support so I decided to take the gamble. I got my P1 five days ago and I’m dead in the water. I’m just starting my day and there’s a pile of email yet to open because I reported the problem on the forum before I gave up and went to bed last night. So maybe, just maybe, some kind soul will have left instructions for me to get up and going again. But I suspect I’ll have to fill out the support form and hope someone in China will help me. YouTube is loaded with praise about Bambu Lab products, but I haven’t seen one yet that addresses support.
I understand you checked for obstruction below the bed but have you checked below the printer itself that no poop or other foreign object is rubbing against the belt or pulley/gear? That is if error was from z-axis issue as you think it is but calibration failure can also come from an unstable surface. My first calibration after printer unboxing was due just from that, I was too impatient and just tested the printer on the first empty spot I found in my workshop which was too wobbly for the calibration to pass. Have you moved your printer by any chance?
Under the printer? I must be misunderstanding you. I don’t know if I’ve ever seen under the printer. I’m pretty sure there are four rubber feet there, but no openings where debris could enter the works. I’ll take a look. Maybe I’m wrong. No, I have not moved my printer before the failure, but thanks for the questions.
OMG! You showed me! I can’t believe there’s not some kind of cover over that! Looks like a good 3D print project. I may have very well had some debris in there, might still be there. I’ll be taking a look. Thanks Philch
My P1s sits on an 18inch paving slab, to the front right of it. Room for a poop collection shoot to the rear lhs. It helps with vibration reduction, and raises it above the rest of the bench, so less chance of stuff going underneath.
But I’ve just requested an online quote from a local supplier online for a plate exactly like this one below (uploaded a dxf file with the cutouts, drilled holes etc) and received an immediate quote: A polycarboante plate whether 2 or 3mm thick cut to the exact shape only costs between 10 and 12 euros… If I want one, not sure I will bother printing
I’ve seen the concrete tile suggested over the years but never tried it for myself. I have a very sturdy counter that my mini and P1 sit on. Do you think it would make a difference if I went with the concrete?
I clicked on your Ali-Express link. It says “no longer available” and it also says $30 USDollars for the plate and over $70 for shipping. I think I can piece one together with PLA. Thanks for sharing.
