Hello all. I had the same issue for a very long time. It was very frustrating, to the point where I gave up and stopped using my machine for several months. I believe I have finally found a solution and I hope this helps everyone. Its been working for me for a couple of months now and I can switch from a laptop to a desktop and it connects right away. Anyways what I did was a firmware update NOT a software update. Here’s the link Snapmaker 2.0 Firmware Updates and Downloads . You need a USB drive. I went to the link downloaded the latest firmware onto the USB drive then went to the snapmaker and connected the USB I then powered on the machine and went to settings went to Firmware Update clicked on that then updated and its been working beautifully since. After you do this update if there’s any other updates required you can now just go to the settings on the touchscreen and they will automatically be on there you just have to hit update. Hope this works for everyone.
