Hello everyone, while my new A350 works perfectly fine so far and I am pretty happy with the first print results via USB, I am still not able to connect via WiFi. on my PC I am connected to the router via LAN cable, so I guess that’s the reason why Luban cannot find the Snapmaker 2.0 on auto search. But I can connect wizh the printers IP. The Snapmakers toch pad then wants me to accept the connection, but I then only get a white screen in Luban (showing only the menu bar). I could find one other user reporting this issue, but with no solution. Perhaps anyone else can help me? Thanks in advance gus! 😉 ---

Hi @stefix! I am using Luban V 3.12.3, which should be the latest, I guess? No, when I just use Luban as a slice, export the G-code file to a USB stick and load that to the printer, everything is fine 🙂 ---

I am also having this same problem. The problem did NOT exist in Luban 3.11. The problem seems to have developed somewhere in 3.12, and has carried on to 3.13. I have an A250. My firmware version is V1.10.1\_20200822. My current version of Luban is 3.13.0 ![luban313-1](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/c/cdfe9c5653d99510dda0871a1f376b1bc30fefb5.png) ![luban313-2](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/d/d8095fab8e4c9bc41ca3707f11a1f6e431f8a3fd.png) ![luban313-3](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/e/ecda4447d5bd0196c036116d20a4a8bff4703576.png) Please advise. ---

Hello everyone, I just want to let you know, that the snapmaker team is still in contact with me. Currently a software engineer seems to work on that bug. You can also find it this bug appearing on Lubans Github page with high priority: [https://github.com/Snapmaker/Luban/issues/640](https://github.com/Snapmaker/Luban/issues/640) I will let you know when I learn something new 😉 ---

It’s been high priority for 11 days, but no-one is assigned to work on it. Perhaps we have different definitions for the meaning of ‘High Priority’. ---

Nobody knows. There was a pre-release version put out a few weeks ago to prep for the rotary module. Next release probably won’t occur until the rotary module ships. ---

I hadn’t used my A150 in a while, so when I went to use it today, I updated both the machine and the Snapmaker Libyan software (on Mac OS) with the latest…… I never had this issue before, but now every time I connect via WiFi to my A150, the Snapmaker Luban software goes blank (just a white screen). Any help would be greatly appreciated. ---

Hello there 😉 There is a new firmware available for the Snapmaker2: V1.14.2 So I would recommend updating it via Wifi or USB-stick.
