I updated my Maestro from 3.2.2 to 3.3 the other day and it all went perfectly.
I updated from 3.3 to 3.4 today by uploading the Duet2and3Firmware-3.4.0.zip via the webUI and it hung on installing firmware update. I left it for a good 20 mins but no response from the webUI. Rebooted and I'm now unable to ping the board. I tried going back to the 3.3 firmware and still no response.
I noticed that there is no DuetMaestroIAP.bin file in the 3.4 release. Could this have caused an issue whilst installing the 3.4 firmware?
Any tips on getting this sorted?
