3 months, still no help from P1P - anyone have suggestions?

I’m somewhat more hopeful that Bambu Lab’s poor support will be addressed. I was able to reach out and connect with Yi Tao, the CEO and gave him a complete rundown of all the nonsense I have been put through over the past 3 months.

So I’m really hoping someone can help me get this thing working - or allow me to return it for a refund. Here is the current situation:

I have replaced the thermistor, the fans, the extruder, and I’ve disconnected and re-connected everything the WIKI suggests. The printer still does not function. When I turn it on, it waits about 5 seconds, then the error, “HMS_ERR_0500_0300_0001_0002” flashes for maybe 1 second. Then nothing happens for probably 15-20 seconds, then the same error returns and doesn’t go away.

I have already checked everything listed on this page: HMS_0500_0300_0001_0002: The toolhead is malfunctioning. Please restart the device. | Bambu Lab Wiki

Interestingly, I disconnected the toolhead cable, powered it on and still received the exact same error in the exact same way: it pops up for 1 second, disappears for 10-15 seconds, then reappears and stays.

What else should I be checking?

Thanks & thanks to Dr. Tao for listening and considering your customer’s voice.

what did the CEO say about allowing you to return it for a full refund?

I’m genuinely confused, you were able to talk with the CEO about all of your problems with the machine but you were steered here in the forum to hope someone else here can assist you? How has that increased your faith in their customer service? Why was there not a resolution after talking with the CEO of Bambu Labs?

I’m sorry I can’t assist with that error but if I talked to the CEO and it escalated THAT far I’d think a brand new machine and a bunch of filament for my 3 months of trouble would be enroute and my broken one being packed up for return would be in order… something doesn’t add up.

Start from scratch with a full factory reset, as if you’ve just bought the printer. If it doesn’t work, raise another ticket.
I agree with @ExtremeElementz , if you got to actually speak with the CEO, surely the topic would have turned to “can I get a replacement machine please and put this behind me”?

Remember this is the person that “Had the worst customer service” over the “$5” thermistor replacement. They didn’t want help, just to air their grievances. The whole story doesn’t make much sense.

I didn’t say I verbally spoke to him. I said I was able to get into contact (aka - electronically). Nobody sent me here - I am waiting for him to get back to me with whatever they decide, but in the meantime, I’m just trying to get the thing working because I actually have projects I need to complete. If between now and the time I hear back they decide to replace it, that’s great, but I’m not holding my breath. I’m not an “influencer” like the 3D Printing Professor - who, after having issues with his unit, not only got a brand new AMS sent to him, but eventually was sent an entirely new X1 as well.

I already have done a full factory reset - still no go.

I didn’t ask for anything free - in fact, all I did was express how poorly the company was being seen by a number of people who couldn’t understand why we had to send in numerous photos over a large number of days, write out a service number on paper (and again, when I asked about this I was told it’s because Bambu customers frequently try to get free parts, so they have to be cautious - aka, we’re all thieves and liars), and so on - expressing how it’s damaging their reputation and that’s the sort of thing that can cause a company to suddenly find itself without customers. (I used to be a consultant years and years ago and understand how quickly bad customer service can damage a small company).

@JonRaymond what are you talking about? I am new to 3D printing. I didn’t know what any of the parts were called. What I did know is that over the course of weeks and now months, I was asked to keep providing more photos, copies of my invoice, copies of the packing slip, photos of a QR code, pictures of the part, and every time I would send a photo and description, I would be told they need more photos and more proof that I actually owned the printer.

When I sent them a photo of the connector from what I now know is called the thermistor, they sent me a cooling fan as a replacement part. Then, when I told them they sent the wrong part and sent additional photos, they sent me the front cover to the print head with the other fan in it. Again, the wrong part.

When I took photos of them together and explained they kept sending me the wrong part - they told me, “That part isn’t covered under warranty”. That’s when I tried to figure out what that part was called and eventually learned it’s a cheap part to replace - which just infuriated me because I was jerked around for 2, now 3 months. What part of that doesn’t make sense? Would you like to see all the photos I had to send? You’ve seen here other folks talking about the same thing. It’s totally unreasonable. No other tech company I’ve ever dealt with has had this poor of service. And again, I’m thankful at least that someone at the top is listening - I would really prefer to just have a functioning printer, but if not I’d like a refund.

Keep in mind, I sent probably a 6-10 pictures of the defective part and used a macro lens (extreme close-up) to be able to show exactly what the defect was and what the part was. And again - I had no idea what any of this stuff was called. I just knew that the connector was defective and was marked “J2 10” and had 2 white wires and 2 transparent wires. I figured since they are the manufacturer, they’d know what that was.

So, with all that in mind - any other ideas on that error message? It pops up for a split second, then after 10-15 seconds it comes back and stays on the screen.

That first picture is all you should have had to send BBL, as the piece is definitely broken. I believe it may still work ok when fitted, as it will still be held in place and connect the right pins to their corresponding pin. However, it’s possible that a couple of the pins have shorted out when it’s been taken in and out, which has damaged the actual circuit board, and is why you are still seeing the error. I would check thoroughly that the missing plastic piece isn’t still in the connector slot, which would prevent the plug from seating correctly.
I know this is not the course of action you are after but I would purchase a new hotend assembly and then write to BBL stating that you have taken things into your own hands and purchased this as they keep sending the incorrect parts. The assembly will come with everything already fitted and new plugs so if it fixes the machine then you know it’s not damaged the board. If it doesn’t fix it, then at least you have evidence that you’ve fitted several new parts in one go (an assembly), and that the fault is definitely beyond what is considered a “normal maintenance” or repair that can be done by the user. You may be having issues with proving BBL at fault, as unfortunately the plug looks like it’s been damaged by the user (they are fiddly though, so you wouldn’t be alone in damaging them) and all the parts in the assembly are considered consumable items, so aren’t covered by warranty. Surely some good will needs to be applied by BBL, as you are right in that just by your actions here, does not look good for other owners that may be having issues with their machins.

@FusionMTSU Did the CEO contact you and attempt to resolve the situation where you stopped the lawsuit against them? I am still baffled that it got to that point, and there wasn’t a resolution way sooner than this. Both of my interactions with support were quickly resolved (within a week) with the issue being corrected. Neither time did they go above and beyond, but they did a 1-for-1 part replacement, which is still satisfactory. I’m sorry your situation has been far from that.

Well “lawsuit” sounds grander than it is - a small claims court suit is for less than $500. The good part of this type of case is, no lawyers are allowed and it would take place in the plaintiff’s (my) jurisdiction. That would mean BBL would have to come to Tennessee, then drive an hour outside of Nashville to go to the county courthouse - all to settle a $500 suit. Most likely they’d never show up - I’d get a judgment in absentia - they’d have to cut me a check.

But at the moment all I can say is, I apparently have made enough noise and gotten the attention of the right people. Some discussions are supposed to happen this coming week and I think things will turn around. I get the feeling that people at the executive level had no idea how many people had been complaining and had felt like they were treated poorly by customer service.

When it worked, my P1P was the most amazing thing I think I’ve bought in years. It’s incredibly fast and the prints looked amazing (for the 2 weeks it worked) I was ready to tell our university to switch to BBL since all the MakerSpace printers we have are old Makerbots and they’re scheduled to be replaced (around 30-35 printers) - but after how I was treated, there was no way I’d make that recommendation - if anyone at the university was treated the same way I was treated, the blame for suggesting BBL would be squarely on my shoulders - and I don’t have tenure yet.

I’m betting that’s the scary part the higher-ups at BBL are realizing now - how much damage has been done to their reputations when it comes to support and service. Big companies and universities don’t want to fix anything - they want good, fast, reliable support. The moment they think a company is unreliable when it comes to support, they look elsewhere. And BBL surely cares a lot more about selling to universities and large corporations than to individuals.

As for the connector - I’d never removed anything until I received info from support to check the Wiki - the wiki said to check the connections on the print head. When I removed the 3 connectors, I noticed the one to the thermistor looked weird & when I looked with a magnifying glass I saw it was missing a chunk of plastic.

Of course, now it seems like that possibly wasn’t the problem since I’ve replaced it and I’m still having issues. It’s all been very disappointing, but here’s hoping for a positive outcome.

The thermistor/heater cable which you’ve shown with the broken connector is an issue but highly unlikely to be what’s causing the main error

It seems like the motherboard isn’t connecting to the toolhead board.
The toolhead cable - wiki bambulab com/en/p1/maintenance/toolhead-cable
is fairly easy to connect wrong - so worth checking that’s properly connected on the back board of the toolhead, in fact all of the connectors are fairly easy to connect wrong. So worth going through that doc and all connectors and making sure they aren’t too far up/down/over so that only partial pins are making contact.

Also worth taking the back panel off and checking the toolhead cable where it goes into the main control board to make sure that hasn’t vibrated loose too.

Ideally it’d be nice to just get the printer RMA’d but it’s weird that it worked fine for a few weeks then just stopped. Could have been a connector slightly loose from shipping that rattled off whilst printing.

If you put photos up of all the connectors I’m sure people will help :slight_smile:

in before FusionMTSU disappears for suggesting litigation and can no longer comment due to pending legal decision :smiley:

How did you contact the CEO? Id love his email

I’d also like to know how to contact CEO if you can let me know how you did it?
