Biqu B1 stops printing

[Donnie Glover]

I have a new Biqu B1 printer and on it's first print, it stopped halfway through the print.  The screen would not respond and I had to shut off the printer and start over again.  It printed with no issues the bear that came with the sd card provided, then I printed the pokemon thing, again no problems.  But now it will not print anything without stopping, and it stops at different points.  I have tried different SD cards, using adapters for the sd card and not.  PLease help...I just bought this.

Hi,

Thanks for your feedback.

Does the disply work fine?

Or there is soem erro message at the dispaly.

Does it stop in the middle of printing ?

The only error message I ever got was "echo M104 invalid extruder 1".  The display works fine.  I have tried different prints and each one stops and even stops in different places.

good night, I have the same problem, I tried to print the test model of the card but it stopped printing, when restarting the printer I came that the files had been deleted from the card, I downloaded a model on thingverse, but it gave the same error

 I gave pause in printing however the printer returned printing about 15 mm up on the Z axis

Hi ，
Thanks for your information.

Printing stops suddenly in the middle of printing.
1. Can you still tap the screen? If you can tap the screen, it means that the quality of the SD card is not very good, and there is a problem of poor contact during the printing process, which makes it impossible to access the SD card. You can try another SD card.
2. If the screen cannot be clicked, it means that the communication between the display screen and the motherboard is disconnected, and try to update the firmware. If the firmware is updated and this problem still occurs randomly, it may be that the display or the motherboard has some defects, which can be tested by exchanging a display or motherboard.
