Printer Stops in the middle of the print

Ok, I just tried printing and I have a message stating “A microSD card needs to be inserted before printing.”. I’ve never seen this message before, so I think the SD card issues stated before may have merit.

I had the same problem. The printer stops printing three times already and goes offline. At first I thought that the reason was in the SD card, but after formatting it the problem remained. There is a problem when printing one small part, when there are 40 of them on the table at once, the gcode file size is 45 MB, maybe this is the problem? When I print 15 parts on the table, everything is fine, the printer does not stop.

Maybe someone already had this problem?

I had a similar bug on the ongoing print that stopped extruding filament in the mid-way.

I have a repeated problem with the PLA marble prints, the job stops extruding after several hours, and the extruder still moves after several layers in the air!

I had to stop and try to extrude manually but there was no movement to bring the head closer to the front door and I got this message.

it does go to home and stay at the poop shoot area. I can’t move the xy axis because the filament is still in the nozzle sensor detection. (green dot on the LCD screen)
after removing the Hall effect sensor I noticed that the arm magnet got stuck in
the corner of the plastic slot casing!

As you can see the arm can sit on the corner without a filament in place!

The Picture below is when a Filament is detected present in the extruder.
FilInPlace

This is a problem and maybe explains why I can’t move my XY extruder.
somehow the firmware interlock takes over to lock any movements.
I ended up grinding the corner so the arm could slide back down without restrictions.

Please make up a newer design with a 45-degree chamfered edge on the plastic casing or the magnet arm.

Besides I am very happy with my X1C!

Is this what I’m dealing with and getting no error codes or help from CS? This ■■■■ has been driving me crazy for months, and I have wasted so much filament I just stopped using my P1P. Since I can’t use my A1 either I’m back to trying to fix this same issue with the P1P. CS is so slow and not helpful in the least with this.

I found the TH cable was pinched in the housing and there looked to be a little black on the TC cable board. When I take the TH apart to swap cables, I’ll look into this too.

I also think I saw a Youtube about this and the guy used some hack to fix it. Is this another poorly sourced part used by Bambu?

Did your modification work? I’ve had this occur twice in the last week.
Maybe it is Hardware because the P1 series owners in this thread have the same problem. For some reason, I guess the X1 series has an entirely different FW than the P1. X1 series is running in a Linux variant. I don’t know what the P1s are using.

I’m curious if that HW mod worked. I find it puzzling the function of it running out of filament would not move.

I suspect one of the boards has an issue, or there is corruption on the FW/OS somewhere. I’d reinstall the FW if I could. Bambu took away the functionality to downgrade or reinstall the firmware. It is only possible to upgrade if one is available.

I opened a ticket, but based on the automated response, it said they were out of the office for the Chinese New Year. Based on the no response many people are encountering through out this Forum, I don’t have much confidence in their Warranty.

I love the printer, but they have some technical problems and terrible Customer Support. Maybe the price of the printer should be lower since Customer Service and a warranty appear nonexistent.

Well, see what happens with my ticket. Oh ya, I bought mine at Microcenter and keep reading during ticket creation that I should contact them for support. If they want to “be like Apple,” they need to support their product no matter where it is purchased directly.

I read here somewhere that Microcenter is taking back A1s for cash or exchange.

yes, I get less false filament sensor report, but I still can’t move the XY while in jam mode. it’s a software restriction I guess.
When a broken filament is stuck in there, I power off then heat the extruder at 250c and push manually a new filament through the extruder to force it out.

My P1S has been working flawlessly for months and suddenly today it started stopping mid print. What happens is: it starts the print normally, then after an hour or so it just stopped mid-print, and its screen showed “ready to print” instead of the usual “printing x file” message. The screen controls were completely unresponsive, so I couldn’t manually pause or stop the print. After a minute or so, the printer just resumed printing on its own, but it had created a blob where it had stopped.

I thought it could be a glitch but after 10-15 minutes it happened again, on a different side of the print.

I see some people refer to the sd card as the culprit but if I remove the sd card the printer doesn’t let me send a print over wi-fi? It says insert an sd card, so not sure what else to do?

Has there been any formal response on this?

Welcome to the forum.

Yes the P series has to have an SD card installed as the print gcode is stored there.

I would try a different SD card to see if that is causing the issues you are experiencing.

Thanks for the response. I had just upgraded to the last firmware version, so i did two things: I downgraded to the previous firmware version, and i also cleaned up the sd card (deleted all videos from it) and I deactivated timelapse. The print so far is working with no issues, so I don’t know which of these was at fault.

Mine stopped today for no reason. I have a P1S. The print was about half way done and when I checked the print head was just sitting there with filament in it but the screen said ready to print. My App said print canceled but no one cancelled it. I took pictures because I didn’t know what else to too do. It looks like the bed lowered too but it didn’t retract the filament. It’s very odd but I’m trying the print again but trying the other plate this time from the same print.



I’ve found this to be the process of which “Step-Loss” occurs.

I wanted to chime in with my experience as well. My three (almost four) month old P1S (with AMS) has paused twice now over the last two days. Both times I was standing right in front of it. Yesterday it paused for about 30 seconds and then continued, as if nothing had happened, and finished the model without issue. Today, while printing a different model, both the main display and the Panda Touch went dark, as if power had been removed and restored (both the P1S and my PC are on the same UPS and the PC stayed on). The Panda Touch reconnected with the P1S, and again, after about 30 seconds, the print resumed. The pause today was about an hour and a half into a four-hour print (it’s still printing with 40 minutes remaining). Both of these “pauses” have occurred since I updated the P1S’s firmware (about three or four days ago), and both have happened about an hour in. After reading through this thread, I’m wondering if I should replace the SD card with a new “high end” brand. I had begun to believe this machine was flawless, not so much, I guess.

This may sound outlandish, are we being hacked from/at MQTT Broker? With constant reboot, stop, cancel prints?

Could you please confirm if downloading to an older version would resolve the issue? Were you using any client to connect (Handy/Studio/?) to the printer when the problem occurred? Were you viewing Liveview at the time?

It appears that the print job may have been canceled by a command. Were you connected to Handy or Studio during the printing process? Could you please share the logs from your SD card so that we can confirm if there was a cancellation command?

It does seem like it might be a power supply issue. Could you please confirm if your panda touch is powered by the printer? Would there still be issues if the panda touch is not used?

@rocky.chen not sure if you have access to reddit. Some resolved by going LAN mode. This is a widespread problem!
