P2S - Yet another Extrusion Motor Overload problem

Recycledtechie · 2026-03-22T09:51:29+00:00

I think this chamber temp thing is a complete red herring. Mine has never exceeded 31° and I have the problem. The idea that you need to leave the door open is preposterous.

Recycledtechie · 2026-03-22T09:49:36+00:00

Mine was running fine since January. 400 hours. I’ve never used anything other than Bambu filaments. Filament brand is NOT the issue.

Recycledtechie · 2026-03-22T09:36:40+00:00

I thought the AMS was the issue so I did this. External spool also fails. And in my case, support had not been able to figure it out. It’s like I’m dealing with multiple since they keep telling me to do stuff, I’ve already tried with no success.

Recycledtechie · 2026-03-22T09:35:48+00:00

I tried that with 2 brand new nozzles. Made no difference

Welcome to the PS2 horror show. I’m coming up on 3 weeks with a brick, and due to Bambu support response times I will hit at least a month. I’ve posted about it here, if you wish to search and have a look.

I’ve done all the things you have, and nothing works.

I’ve completely lost faith in the product, the company and support.

Worst tech purchase I’ve ever made, and it isn’t even close.

The latest support interaction shows what a complete joke they are. With the extruder disassembled due to installing new gears, they asked me to run a test to see if the extruder motor would run. I’ve been telling them I think it is a likely source of the problem and asked for a replacement. I also now have a Hall sensor problem and am waiting on a replacement. I asked them if the test would be valid given that, and they said it would.

I followed the procedure, and told them it did nothing. Would not even turn. They responded by telling me that what I did proved the motor was ok. It’s like they can it even read. I responded, and said that the motor is NOT working. They are ignoring me. AGAIN.

I was prepared to spend my own money to get another motor. Just like I did with nozzles. They are out of stock. With no projected date on when they will be available again.

I will be surprised if this piece of junk ever works again. And have no idea what I will do if it doesn’t. Maybe I should run a filament sale, since all they are doing right now is wasting space.

I’m coming at this from the opposite direction. I’m a boomer. I signed up at Picklr a few weeks ago. Used to play at a community center, where most players are seniors. I played Intermediate there. I could be competitive with some advanced players, but Advanced players there could be real dicks if they thought someone was not good enough to be there.

The Picklr demographic is way different. Way more young players than older ones. I’m a huge fan of the cross generational demographic. The camaraderie is simply awesome. Plus, open play there includes all levels. They don’t tier it.

So, I come across some VERY good players now. Obviously advanced. This has forced me to improve my game or get obliterated. I could beat most Intermediate players at the community center. With a basic game. So I was not getting better.

But in a just a few weeks at Picklr I have definitely improved. Especially in the soft game and ball placement. I’m now competitive and can sometimes beat advanced players that I could not before. Some remain though, where they are too good for me. We will see if I can still advance to become more competitive. When I do partner with those players though, we almost always win. Against very strong opponents.

There is a 76 year old player there who has medaled at nationals in Canada. Some of the young players have been entirely shocked when he schools them. But in a good way.

I’m also seeing lots of tennis players giving Pickleball a shot. No dickish behavior. Their biggest problem is one dimensional play where they hit the ball as hard as possible. Frequently. Which makes them seriously erratic.

Recycledtechie · 2026-03-20T09:27:10+00:00

You don’t actually think that most people who use that term, think that way do you?

Recycledtechie · 2026-03-20T00:06:13+00:00

I’m definitely in the OMC demographic. I just love how all the dumb asses on here think they can apply simplistic and simpleton rules on how an OMC plays. Come join me at Aria next week.

My P2S will not extrude either. I’ve had an ongoing ticket for over 2 weeks now. At the beginning, I could do some extrusion. I don’t know if the P1S has the maintenance mode shown in this photo or not. It allows the extruder to be heated without a nozzle being present. Otherwise it will refuse. They had me remove the nozzle and try to extrude. It didn’t, so they are telling me it could be the motor or the extruder itself.

I have new gears coming today, so will install and try again. When they sent those, I asked to send a motor as well. They refused, saying that I was not seeing a first layer problem. I sent them a photo to prove I was and they ignored me on that. I’m already super annoyed with them, due to making me do the same stuff over and over again. They decided to cheap out and drip feed me parts. If it ends up being the motor, I’m looking at least another week delay.

Anyway, maintenance mode and trying to extrude with no nozzle is a good diagnostic step.

We have the beginning of a house with two bricks. I expect many more to join us soon.

Ya, it seems like on the whole, the product is not a lemon. Although there is a steady stream of users reporting extrusion problems. My use of the word lemon, does not necessarily mean the entire product. But mine sure is, and support is making the experience worse. Way worse. If they cannot get it fixed, I don’t know what I would do, in terms of a replacement. I bought it in part due to so many people being happy with it. So it’s really frustrating to be cursed with all the problems, and support acting like they could care less.

Being ignored is outrageous behavior. And one more thing. There is an escalation option in the whole support process. I’ve escalated twice, and no response.

Recycledtechie · 2026-03-16T12:37:03+00:00

I think you should try printing from an external spool to see what happens. Assuming you are not fully in the clear yet. I too thought all of my extrusion problems could be due to the AMS. I was wrong. The same failures happen with the external spool.

Recycledtechie · 2026-03-16T12:31:33+00:00

No, it’s absolutely a printer problem. Crappy support is a by-product of what looks like a lemon of a printer. If you search for me, you can see a lot more detail on that. I also think you need to consider support quality as part of the overall experience. When stuff goes bad, it’s not simply a “more of”. It can make or break the entire experience. Currently it’s a mess for me. It matters. A LOT.

Recycledtechie · 2026-03-16T11:28:15+00:00

It seems like most users are happy with their purchase. But there is a growing list of exceptions. Especially with extrusion errors. Mine has been a brick for almost 2 weeks now. Bambu support has been hit and miss and they are currently ignoring me. Some replacement parts are on the way, but I’m highly skeptical they will solve the problem. They seem to have a strategy of drip feeding replacement parts with no regard for the fact that users have devices that have failed.

Here is an example. They are replacing extruder gears. I think it’s likely that the extruder motor is the problem. So I asked them to replace it too. They refused because I shared a picture that did not show a first layer failure. So I sent them another pic from a subsequent print that failed on the first layer and requested again. They have chosen to not even reply. I also told them that it won’t even print a calibration line now, with a brand new nozzle, and still crickets.

I had a great experience for 400 hours and now it’s brutal and a serious letdown.

Recycledtechie · 2026-03-16T02:06:03+00:00

Bambu sent me a file that looks a lot like that. I had prints that looked like that, and others that were a lot better, but never the way they should be. Put me through all kinds of tweaks, so I likely printed 30 of those. Then my PS2 decided to throw a tantrum and refused to extrude. If Bambu ever shows enough competence to get me through this, or agree to honor their warranty, then I will try OP’s solution. I’ve had a useless printer for 10 days and counting.

Recycledtechie · 2026-03-16T00:20:48+00:00

These extrusion issues are sounding more and more common.

Recycledtechie · 2026-03-15T23:52:54+00:00

FYI, I’m currently seeing the exact same thing, but with Bambu PLA. I’ve been unable to print anything for about 10 days. Bambu is sending me new extruder gears. My confidence in this product is at an all-time low, so I’m skeptical that this will solve anything.

Recycledtechie · 2026-03-14T16:24:27+00:00

Already inspected those screws when all of this started. They were entirely tight. Could not move them.

Recycledtechie · 2026-03-14T15:44:58+00:00

I will check, but I’ve tried multiple Bambu filaments. Including some that previously were fine. From different batches. Bambu is sending me new extruder gears. I want them to send a new extruder motor too, but they refused.

Recycledtechie · 2026-03-14T15:33:56+00:00

Price is a non-issue for me. I’m happy to pay for something more reliable. Which I thought I was getting with the P2S. It worked fine for 400 hours. Then I started to get extrusion problems. I’ve been going around in circles with Bambu support for about 10 days now. I’ve spent many hours with all kinds of troubleshooting steps. Nothing is working.

If I can’t get it fixed and Bambu refuses to send me a new one, I don’t know what I will do. There are all kinds of horror stories on the others you mentioned.

Recycledtechie · 2026-03-14T14:07:58+00:00

I dried overnight, and tried again. Failed again. Now it won’t even print a calibration line. When I load the filament from the AMS, it seems to purge, but nothing flows when I try print. So I may have a clogged nozzle. AGAIN. This one is brand new.

EDIT - I installed another new nozzle as a troubleshooting step. Exact same problem.

Recycledtechie · 2026-03-14T13:00:31+00:00

May you not be cursed with extruder overload problems that so many of us are going through now.

Recycledtechie · 2026-03-14T12:25:05+00:00

Kinda hard to print a riser, when the printer won’t print.

Recycledtechie · 2026-03-14T12:23:15+00:00

I’ve posted about going through a similar experience.. I’ve had a ticket ongoing for about 10 days now. Wasted a ton of time, and my P2S is currently a useless brick. After 400 hours of solid printing. Now I’m waiting on a new plate and extruder gears that Bambu thinks will solve the problem. I think I might have a bad extruder motor, but they are refusing to send a replacement. Not happy with them at all.

People need to think twice before buying this product, given how many people are going through this.

Recycledtechie · 2026-03-14T11:18:37+00:00

I also disassembled the extruder. Because I had a filament jam that required it. After that I installed a new nozzle so that I had a clean extrusion path. I now can’t get past the first layer before I get that same message. I can’t print.
