Hi Guys,

Wanhao Duplicator I3

I bought Wanhao Di3 v2 last week and it worked fine, with most of the prints coming out quite good. I printed everything from Micro SD card, that came with the printer, and it worked without a problem until yesterday.
I started the print as usual, and at some point I noticed model is not firmly attached to the print bed, so I decided to stop it (from the menu - SD card - Stop Print), took out the SD card and went to PC to reload the file with Raft.
When I got back to printer and inserted the card again printer didn't see it anymore. Sure, I restarted device, went to menu - SD card - Mount card, but it only holds for a few seconds, release a beeping sound and starts small cooling fan for 2-3 seconds. And then nothing. It doesn't load the card. I tried restarting printer a few times, unplugging it completely from the power source, and powering it again but with no difference.
Card still works without any problems when plugged in PC.
Soon enough I was reading about problems with stock cards that came with the printer, and advices to buy a new one, and while mine was working fine in PC, I went and bought 8GB Samsung EVO card. But the problem remained.
Both cards work without a problem in PC, but printer just wont load them.
I also tried to format the card with SDFormatter, it went well, without problems or errors, loaded a fresh Gcode in Cura, but i3 still doesn't see cards.

I was also unable to print directly from Cura, although my laptop sees the printer when connected to USB. When sending file from Cura to printer, it only says opening COM3 port... and then it never prints.

So if anyone had a similar problem, or has an idea about possible solution, I would love to hear it.
