I have a bit of a different problem. With Studio 0.25 on my Mac (OSX 10.10.5), I was able to connect via USB to configure the wifi. That works fine. I went through the procedure to update the firmware using a USB stick, and got the expected sequence of red/white flahses. However, once that is done and I restart the printer, I can still connect with 0.25, but not with 0.27. When I start 0.27, the window comes up and the spinning circle os there endlessly. Left it for many minutes with no change.
Any suggestions for troubleshooting?
