I forgot that some people only got the 3d printing module ; it was a stretch to test with another module anyway. I am not sure what you have had experience with, but cura might be the most accessible to test with. Below are the machine settings for Cura that Noah had shared a while back.
If the printer still freezes up with a print file prepared from another slicer, it might be time to try printing via the usb cable. I guess there is a chance there is an issue with the reader or the sd card?
My snapmaker was freezing up when I was trying to change filament the other day and after a few reboots the issue persisted. Ultimately I got it to start working after I turned it off, unplugged the power adapter from the unit and from the wall. I then unplugged and plugged each of the ends for all of the cables and left the unit unplugged from power for a good 5 minutes. I then plugged the power back in and turned the unit back on. After that it was back to printing. After going through that I think the cable going to my print module was loose but it took reseating it and leaving the unit off for a while before it fully recognized that it was plugged in properly. It may be worth giving that a shot…
After that my opinion would be to try to flash latest firmware or re-flash if you are already on the latest.
It looks like the firmware is posed on the downloads page of the snapmaker site under “Additional Files for the Software”. The instructions are included in the zip file.
Oh one more strange question… You wouldn’t happen to have the snapmaker plugged into a surge protector or a UPS would you? Whether you do or don’t should really matter, but under these circumstances I usually plug strait into the wall and possibly move to another outlet. I know it seems like a pointless exercise but I have seen some things… I had a server once that would shut down randomly… turns out it didn’t like the sine wave the UPS was putting out… idk way over my head (http://www.apc.com/salestools/RMUZ-7DTKRC/RMUZ-7DTKRC_R1_EN.pdf)<-- Don’t bother reading that, just wanted to attempt to prove that I’m not crazy. Anyway, I know that was way off topic, but like I said, may be worth plugging straight into an outlet or moving to another outlet if you have easy access and you haven’t tried it already if only just for kicks.
Hopefully one of these steps helps you out and I haven’t wasted your time. Just trying to offer some suggestions until the snapmaker team is available to help you out.
