Printing just freezes

Bambu Lab P1 Series Troubleshooting
1

I’ve only had my P1S about 2/3 months. In that time I’ve had a few small issues but nothing I wasn’t able to find a fix for. This one has me stumped. I did look on forum to see and found a similar issue so I will try what was in there but in case that doesn’t work I want to be proactive and see if I can get some help

Only thing I have changed is my nozzle, got one on Amazon instead of Bambu. It’s been printing fine even with the replacement nozzle until today. I send the file to print. It downloads with no issue, starts heating everything up like it should and then just stops at “heatbed preheating” as shown in photo even though the bed is heated. Any suggestions would be most appreciated

Hi @Obiwan,

Welcome to the forum.
The issue is to generic so some suggestion to eliminate a few causes:

  1. If you dont have any data (e.g. AMS k-values) just reset your printer, calibrate and try again.
  2. If you do, check if the firmware is updated, update if necessary, hard reset the printer and recalibrate.
  3. Replace the memory card;
  4. Update the slicer if necessary; try printing another file.

Let me know if the issue persist.

Thanks for the tips.

So I did a factory reset, calibrated and did the self test and it all went good.

Replaced the SD card with a new one

Firmware is version 01.06.01.00

As for the other things you asked about, if you tell me where to find them I’ll happily provide.

Currently trying a brand new print and it’s been sitting on same screen for 5 minutes which never happened before. And has yet to start the new print

I am sorry it didnt work.
At least that eliminates common causes.

I am lost with this one. The first image shows that the nozzle is still heating … but after 5 minutes, it isn’t usual to be stuck.

  • Since you replaced the nozzle, double-check if the cables are firmly connected at both ends or return to the older one.

  • As the self-test doesn’t show errors, I will assume the printer is working well. In that case, the issue can be in the file, communication, etc.
    A straightforward test is without using the app or studio, i.e., using the printer display, printing one of the cache files that come by default in the printer memory, e.g., benchy, memory card holder, etc.
    To identify its failure stage, please pay attention to the printer’s behaviour, such as toolhead movement and temperatures.
    If this one gets stuck, too, it shows that the issue is with the printer.

  • If all that fails, open a Trouble Ticket with BL support or use their new service to chat directly with the support team. You already have plenty of info to share. At the same time, while waiting, inform us so we can try to give other tips.

Does the printer hang when printing one of the prints that is included with the printer?

If you don’t have them, they can be downloaded here.

So I have tried 3 prints. 2 of my own and one that was preloaded and the same thing happens with all of them. I did open a ticket so hopefully support has some answers for me. I appreciate all the ideas. It’s just crazy how one day it just stopped.

The log files should give them insight into what it happening.

Hope so. Well now I just noticed a new problem, which could be the cause of the overall problem. The heatbed stays hot. She once I made this post I just had the printer on, but nothing printing of course due to the issue. Went into the app and check on the printer itself and the heatbed was as hot as when you would be printing. App said 65c. If this new information gives anyone new ideas to try let me know. I of course have no shut off the printer as I don’t want or need the heatbed in n all night.
