Pretty much every print over 30 minutes (problem occurs at random times). Everything works fine until roughly halfway or over halfway through the printer just stops. The led lights for the printer bed turn off and back on again for maybe a second and the AMS lights all go red for about a second then they go back to white. The extruder literally stops and stays touching the print. So its not like the print stops and it goes back to the chute or anything like that. On bambu studio it just says printing progress N/A and it’s as if the print had just vanished. On my phone it also says the device is idle and when I go onto the printing history they just say printing. And then when I go to start another print (won’t let me resume the current print as it disappears from the p1p screen) it just goes as if nothing ever happened well obviously it goes until it decides to randomly stop again. Also I never get any error messages from my phone, pc or on the printer. Nothing to tell me the printing is paused or anything either, the printer just says ready to print. I hadn’t changed anything prior to this issue and it had been working perfectley fine before. I usually run the beta version of the studio but I also tried using older versions too. I also turned the printer off and removed the power supply, changed plugs cables all of that didn’t do anything.
Check your printer profile for any changes in the start or ending gcode. Maybe something has accidentally been changed there.
It almost sounds like it could be a truncated gcode file, possibly related to too long of a filename.
I would uninstall/reboot/reinstall studio, and attempt a print using a stock configuration. If that works, try your user presets. If that fails, you have an issue in your profile configs.
Barring those issues, I would look at the supplied electrical circuit and suspect that a low voltage situation may be occuring. Not a complete power loss, but a low enough voltage to cause the board to spontaneously reboot and reset the printer.
Maybe the SD card has a problem
Sounds like a thermal issue to me. Something gets hot enough, it flakes out. The printer does an internal reset, like it’s been power cycled. The job it was running is abandoned as a result. The printer doesn’t move anything when it powers up (which is also starting up from a “reset” state). So it just stops, the lights blink as it resets, and then it behaves like you just turned it on…
You’re going to need BBL help. It’s likely the machine’s logs have information that’d help them identify the faulty component.
Yeah I was thinking this or electrical as AlAmantea mentioned. Thought I would just turn to the forum because I submitted a ticket nearly 2 weeks ago with no response and it feels like an eternity when i’m usually printing all day everyday
If you’re comfortable doing so, open the printer up and disconnect reseat anything that “connects” to something else. If it’s got a cable, disconnect and reconnect at both ends. Might not do anything, but you never know…
Be sure to unplug the printer first ( just to appease the people overly concerned about live voltage ).
Yeah. Good point. That.
This is probably the answer, especially if they are using the supplied sd card, they are chinese junk.
Just had an update they said the issue is with the MC Board and it needs replacing thanks all.
Glad they got you all sorted out.
