Snapmaker A350 printing stops / freezes at 2/3

Snapmaker 2.0
1

HI,

since a few weeks month 3D printing got really a pain. First my whole printing head got messed up after a regular print. Everything melted away…
It was exchanged by snapmaker (thank you) but still 3D printing got worst. I used to print dozens of items without any problems (except of the usual things). Now only 30% of my prints come out usable.

7 out of 10 prints my snapmaker freezes at 2/3 of the print. It just stops with minimnal filament around the nozzle. The firmware / machine seems to be frozen

Iam currently printing again and will attach a picture asap

Sometimes the same gcode works after a few restarts and calibrations.

Anyone else has / had this experience and may tell me what Iam doing wrong ?

How do you print?

  • USB-thumb drive
  • WiFi with luban
  • WiFi with other slicer
  • USB to serial connection (which Slicer.)

What is displayed on the touchscreen when the print stops?

It seems you are printing from your pc/Mac and the communication got stopped.
This could because of a bad connection or standby-mode.

After the next fail, upload the logs to the forum pls.

hi,

usb
display shows x% regular printing screen but system is frozen

4

Which slicer did you use?
Uploading the logs is the next step.
Maybe your gcode or thumb-drive is corrupted (You meant the drive with usb, no serial connection, right?)

Hi,

Iam using Luban as slicer

Iam a new user and not allowed to upload my log… oh come on wtf. Iam enrolled since snapmaker 1 “Update, I uploaded the log files”

Following some log entries from today before it crashed AGAIN.

I have SC_247.log

It seems there is no response from usb.
Any ideas @Edwin @JKC20?
I would suggest to try another thumb drive.

7

i have 3 thumb drives, all behave the same

iam now trying to print via wifi / transfer the same file lets look what happens

9

it is the USB Port on the snapmaker.

I extended wifi range and submitted the gcode to the machine. Now the prints work as intended

Thank you !

Still shouldnt happen

10

You should forward this to the support
Support@snapmaker.com

11

Hi @realfire

Sorry for the late reply.

It seems there’s a lot of garbage in the G-code file. Please send me the file that you failed to print.

Does this issue happen every file you print?

Looking forward to your reply.
Best regards

12

Hi Edwin,

no only happens when iam using USB Port. The same gcode works fine when sent via WIFI.

No not every file some prints worked out

13

Hi Realfire,

Previously, some users used a USB extension cable with the USB thumb and then started to print, which would cause the screen to fail to read the file and stop printing.

Best regards

14

HI,

no extension cable was used, three different usb sticks. All having the same issues.

Please note two month ago the same USB sticks worked like charm

Kind regards

Does your USB contain only your current project or is there more data on it?

16

Also gcode from past prints.

17

Maybe you can try to clear your USB and put only your current project on it. Other devices sometimes have problems with fragmented files.

18

I formatted it and its already printing. Still strange the same occurs on different usb sticks

If you’re using wireless on a pc, windows is able to shut the connection off if it thinks the connection is idling.

Open the adapter dialog, properties, and then Configuration. Find the Power tab and uncheck the first box.

20

after I formated the usb it works. So it seems all three sticks have been messed up -_- still strange

21

At least it works again :+1:t2:
