Warping Issues PLA & others P1S

Bambu Lab P1 Series Troubleshooting
61

LOOOOL
Keep chipping away and you get to the root of the matter.

Yes, it is the plate that shipped with my printer directly from Bambu
Inland PLA

As if Bambu “just in case” runs out of their logo plate. The plate they probably ship EVERY SINGLE PRINTER with. From top of the line X1 Carbon down through P1P. No experience with A Series but my gut says its build plate also has the logo.
Literally like Chevy running out of Bowtie emblems for their pickups. “Yeah, let’s just slap a Traverse emblem on this Doolie 3500. Won’t no one be the wiser.”

Oh, BTW, won’t be near my PC until Monday so sorry, can’t even point you at the model. Danged if I recall whether it is Printables, Thinkiverse, Maker World, Yeggi or Cults.

DUDE…Really?
Your plate does not have the logo and you provide a link to a plate WITH THE LOGO.

I’m not here to pile on, but here’s the plate from my P1S.

Visible logo, just like on my A1 mini. And just like my A1 mini, the lettering is really faint, the gold is much more dull than what is shown in OP’s photos. Same with the extra plates I bought from Bambu.

Kinda makes OP’s look like a cheap knock off, but maybe that’s how they were several months back. All mine are from July.

You know what, that plate that I linked did have the logo. I truly missed it when I glanced at it. I’ll own that.

But regardless, my plate does not. Why? I honestly don’t know, but it is the plate that came with the printer.

Here’s an official unboxing, straight from the Bambu official YouTube channel. Go to 2:41. Look at the build plate. Notice anything? Yup. No logo.

The 3mf file was sent from Bambu tech support. To an email address I don’t have setup on this phone.

My build plate, looks just like the one in the official Bambu labs studio

Might be hard to do, but have you used your temp gun to check nozzle temp?

Ever disassembled your ceramic heater, cleaned and used new thermal compound on it?

65

I’ve not tested the temp at the nozzle. I have replaced the entire hot end with the hardened steel version when I was trying some abs cf & pla cf. It didn’t make any difference to adhesion.

Here’s another thread with someone with a no logo build plate, just for @Wsquared58

I’m going to tell you something. Take it however you want.
Your story doesn’t ring true. You won’t be the first person to bugger up a Bambu printer, nor will you be the last.
If you would say what you did, folks can probably get you back up and running.
I owned a Creality machine. Creality machines teach you bad habits I have been at this Bambu P1S for 6 months and the number of ex-Creality owners that have come through asking for help is pretty staggering.
A lot of folks with way more experience than me and in general they want to help but they also don’t want to waste their time on something that doesn’t really jibe with what a printer will and won’t do.
Like that build plate.
It is extremely unlikely that Bambu sent you some non-logo build plate so how do you come to have a knock-off build plate? And Why??

I have 2 non-logo build plates. Purposefully, waiting on a 3rd Garolite.
You want to go back to basics. These printers have some faults, my first had to go back but my second is a dream come true for someone who wants to make parts from CAD software. The **** with tweaking.

68

Thank you for the explanation. Makes a bit more sense.

If you have friends that have a BL printer can you borrow their plate? Better yet swap plates and have them try to print on yours and vice versa.

69

Just dropping in to solve the build plate mystery… around the first of the year (January 2024) Bambu started putting the logo on the plates.

When one plate works and another doesn’t, it is probably best to go back to basics. Two items I have not seen when running through the thread:

  1. Missing ingredients in this:

Add a clean dishwashing brush, quite a bit of force and doing this repeatedly. The valleys of the textured plate build up residue when not being thorough. By going to 90°C, the grime is likely baked into the valleys. So really give it a number of thorough and rough scrubs.

  1. Is the plate set correctly in the slicer? Happens to me occasionally.

He’s swapped plates with a friend, his plate works in theirs, their plate doesn’t work in his.

I’m sorry you didn’t believe me. But everything I’ve told you is truth. Including when I earlier linked a build plate with the logo on it. That was my error and I’ll own it. It wasn’t intentional, and I’m not sure how I missed it. But I did. No excuses, I messed up.

Since you asked what I did, I’ll tell you exactly what I did:

I unboxed it
Removed packaging materials
Calibrated & Connected to Wi-Fi (though I can’t recall if you have to connect first or calibrate first… These two steps might be out of order)
Put on the gold build plate that came with the unit. I washed it in hot water with Dawn detergent just to make sure there was not any residue on it from shipping. It did not have a logo in the middle. Just like the official unboxing videos from Bambu don’t have the logo in the middle
Loaded the benchy because, hey, let’s see how this thing looks out of the box.
First couple layers looked ok, walked away and came back to spaghetti. No big deal, maybe my shirt rubbed against the plate. I’ll clean it again.
Same result.

Jumped online to see what I was doing wrong. Tried resetting, recalibrating machine, even upgraded to the beta firmware.

Same problems.

I swear on my 10 year old daughters life that I did not change a singular setting. Right now the machine is 100% stock save for the hardened steel.4 hot end. I’m back on standard firmware.

Called bro in law to bring his machine that I helped setup a few weeks earlier over (his works beautifully and still does) to see if I somehow missed something or if my settings were different than his somehow (we didn’t change any settings on either machine to this point) and everything was identical. Including the no logo plate that came with his printer as well.

…

I’m not using any parts on this machine that did not come from Bambu. Exception being the Cryogrip build plate that I mentioned several posts ago that I purchased this past week. All photos are with the build plate that Bambu sent. Period. Even THEIR unboxing shows the exact same no logo plate as does the other post I linked in here from another user.

Here’s another unboxing video. Look at the build plate at around the 3:30 mark. No logo.

And another around the 1:10 mark

I don’t know how much more basic I can go back to. Everything is art stock settings.

Even in the past, I’ve never changed anything other than print speed, layer height, brim, raft, support, temp at nozzle or bed in an effort to get better adhesion. None of it worked so I just reset everything to standard settings and reached out for help.

I’m sure I’d feel the same way you do if I saw someone having the issues I’m having, after everything that should work doesn’t, it looks suspicious.

73

I have been using a dishwashing brush and it’s only ever been used for the printer. And yes, I scrub the hell out of it.

And yes, plate is correct on the slicer.

74

Have you considered reaching out to Bambu Lab about shipping it to them for repair?
I just read the warranty and it looks like that might be an option. Seems like something worth doing as the warranty is 1 year in US, 2 years in EU/Asia.
You’d have to pay for parts but parts actually pretty cheap.

The free replacement is the short 30 day.

75

I’d tried to return it early on. I didn’t hear back from them.

I tried again this week and they finally responded to me.

I’m hopeful, but honestly the fact that the cryogrip plate worked is probably enough for me not to blow it up with tannerite, though I’d still like to know why I need to use aftermarket plates so I’ll continue down the support rabbit hole.

76

Did you look/compare the start and stop G-Code I sent.
Mine is bone stock so it might be worth comparing your G-Code with mine as mine is what machine shipped with and more importantly, it works.
I don’t think anyone disputes that something is not right with your printer but unlike open-source printers, you are in a community where everyone (for the most part) have identical printers, with identical parts and identical software. So while there are a few things that will cause trouble (dirty build plate for example) you are in this community of identical machines.
There is a phrase about comparing two dissimilar things and the phrase is you are comparing apples and oranges.
But in this instance you have 10,000 apples, of which you are one, so why does this 1 apple not behave like the other 9,999.

It might be worth reaching out to Bambu, ask them if you could upload your logs to them and let them parse the logs for something.
It’s that apple thing above why me and a bunch of others think you have done something to the machine because there is no reason is should not print.
Now, I caught some grief when I was fighting with my first P1S and for same basic reason. But because of my job I knew what the deal was but had to go through Bambu’s process which was frustrating but in the end, they sent me a replacement that runs like a dream.

That’s why buying parts is a waste. Printer should run, as is. Me personally, I would not consider a different build sheet that seems to work as a solid fix. Maybe get some micrometers and measure the thickness of the stock vs new plate.
Maybe also check those miniature plug connections in the toolhead because they are very easily misaligned and have probably at one time or another bit every P1, X1 owner.

A note in case anyone asks if you changed the nozzle description in the printer and in Bambu Studio to hardened steel. I didn’t know to do that when I first installed my hardened steel nozzle and all I had was some oozing after the print, no adhesion issues. Realized I’d done an oops and fixed it later.

This is definitely a weird issue. There is always a possibility there’s a physical problem with one or both of the controllers in the bed or nozzle causing temperature fluctuations while printing. Wonder if there’s a hidden loose / intermittent connection that might be causing this issue once the head starts moving and the printer starts shaking?

Read through the whole thread and can’t think of anything you haven’t tried already

Thanks for the advice. I’ve been gone all weekend deer hunting so I haven’t been able to look at G Code. Honestly I’ll have to figure out HOW to look at it as I’ve never even tried to mess with it prior and never had to mess with it on my Creality machines either.

I have finally been able to get Bambu to respond to my tickets (long story, but I submitted dozens of tickets starting on day 3 of me owning the machine looking to return it or exchange it and didn’t hear a thing back… I submitted a more recent ticket to which they finally responded). Because they’re responding and working with me now, I’ll probably continue with their step by step process of troubleshooting before I dive into the g code.

81

Good point on the hardened nozzle. I double checked just to be sure and I was able to confirm that I did set the nozzle correctly.
