HI!
My Snapmaker A350 is not working anymore. The nozzle does not heat up (change filament in menu). I exported the log and found the following line:
1589387330047,2020.05.13 16:28:50.047,ERROR,SC-FW,ERROR: System Fault[0x40000]! NOW cannot heat hotend!
Can anyone give me some hints whats broken?
Thanks!
Have you tried swapping out the nozzle?
Just tried that. But no change 
I have 3 sets of nozzles, none of them work anymore
Probably the controller then. Time to contact support@snapmaker.com
Please contact support for your issue.
Please forward your result to support@snapmaker.com
Thank you
I will check all connectors and then contact support. Thanks!
I think I found the problem, will have to contact support
(thats the printhead side)
I contacted support today. Got delayed by some stuff here 
We will send you some new wires for replacement. In addition, here is a video for your reference.
Thank you! That video is also really helpful.
Hi,
I had the same problem today when replacing the hotend. I managed to push the pin back in. Should I nevertheless replace the cables?
I had the same issue on a 56 hour print job (44 hours in). Email sent to support.

I am having the same issue. After 20 minutes of print, it stopped and went to home position. Temp was back to room temp. Same error in the logs. Tried swapping cables and hotend to no avail and then noticed the same issue with the pin (mine was out completely. See picture.)
I received a replacement cable some time ago but I didn’t have the time to replace it until recently. It works like a charm again (as expected). Thanks.
that probably could have been reinserted, although its very hard to explain if it doesnt want to stay where you have to pry at to fix it.
