This release brings support for dual motion systems on some boards, more types of user input in M291 message box commands, array-values variables, and many smaller improvements to functionality. Be sure to read the upgrade notes and known issues list at https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x-Beta#reprapfirmware-350-beta1 before upgrading! As this is the first beta following major changes to the motion system planning code, it is not recommended for those of a nervous disposition. You may wish to test at reduced motor currents initially.
Other notes:
- CAN protocols have not changed significantly in this release, so version 3.5beta1 main board firmware will work with version 3.4.x expansion board firmware, and vice versa.
- For WiFi enabled boards, DuetWiFiServer version 2.1beta 2 is included with these files; however you can continue using version 1.27 if you wish. In some systems, version 2.1beta2 may give a lower upload speed than 1.27, however it supports additional features such as WiFi scanning and WPA Enterprise (details to follow) and it may work better with some WiFi access points than 1.27 does. Note, if you do upgrade to 2.1beta2 then you will have to re-enter your access point details using M587.
