Hi. I have a problem with my A1 printer. when there is a power failure, it is unable to resume printing, the initial screen always pops up and the printing seems to be finished. I have the most current firmware, I tried installing an older one in case it was the firmware, but it didn’t help. I made about 10 attempts to turn off the electricity during the test and I was always able to throw away the print, not once did the option to continue pop up. (disconnecting the power from the socket, not with the button on the printer) I don’t know what the support hasn’t helped much yet. could there be something wrong with the printer or the software? I tried printing the poster from different sources (printer, phone app and slicer), thank you in advance for the info and sorry for the translation from the translator
First thing to check is that the function is active.
If that checks out, try doing a back up to the sd card and then formatting it with the printer.
Note that my A1 doesnt always recover either, its like 4 out of 5 times.
If the issue persists try creating a ticket if you haven’t already
yeah i tryed shorting my printer that made it power off during a print and it doesnt resume
Hello have you found out what the problem was and how to fix it im having the same problem
yep; i noticed the same. it just refuses to resume now. dunno why.
After a lengthy discussion with support, they sent me a new motherboard. I replaced it and the problem has been resolved for now.
It’s impossible! I have two Bambu Lab A1 Combos, and this is the second time the power has gone out. When it comes back on, neither printer restarts. The “automatic recovery of lost steps” feature is activated. I don’t understand what’s happening. I don’t think it’s the two boards, as I read in a comment, since the printers are practically new.
Lost step recovery has nothing to do with power loss recovery. Power loss recovery is activated by default and there is no partcular setting in the menu to set it on, it is always on. When power returns, the print should be on pause and a message to offer you to resume the print, you hit play and it will resume. It may take some time depending on the file, the time the printer read the gcode up to the line when the power switched off and resume, some A1 users have waited 30min on a big file between the time they hit play and the print resumes.
I have that too! So far, I haven’t had a power loss when printing. But I have it on just in case.
De hecho perdí muchas piezas que solo por no esperar. Me pasaba lo mismo que a todos pero realmente solamente esperando se puede reanudar una impresión. De facto que le cuesta retomar conexión a la red como también procesar el GCode hasta encontrar el momento exacto en donde se interrumpió la energía. Sin embargo el único problema es que dependiendo de la geometría de la pieza, se suele despegar de la cama si se llega a enfriar del todo, con un ratio de éxito del 80%.
I face one different problem today evening, before power failure my printer is printing one object in “by object “ mode when power failure occurs and resume back i choose resume printing and it is started printing when it stops but in “by layer” mode !!! Why this happens any one have idea!??
