Release 3.5beta1

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:

1. 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.
2. 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.

Release 3.4.5

This is a bugfix release. For the list of bugs fixed, see https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x#reprapfirmware-345.

Important! There are no changes to firmware binaries for Duet 3 expansion boards, so they remain at version 3.4.4 in the Duet2and3Firmware-3.4.5.zip file in this release

Important! Some users experienced issues with the printer failing to complete homing in this release. This was traced to an incorrect main board binary file within the .zip file included in this release. The .zip file has been updated with the correct file.

Release 3.4.4

This fixes bugs in the 3.4.3 release that affected Duet 2 WiFi, Duet 3 MB6HC, Duet 3 MB6XD and possibly Duet 3 Mini WiFi main boards. The firmware binaries for other boards have not changed except for the version number. See https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x#reprapfirmware-344 for the change list.

Release 3.4.3

This release fixes a bug in previous software releases for the Duet 3 MB6XD with expansion boards, and supports the forthcoming Duet 3 MB6HC version 1.02 hardware revision. See https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x#reprapfirmware-343 for the change list.

The WiFi firmware (DuetWiFiServer.bin) and IAP files have not changed since the previous release. The Symbols archive files are for debugging use only.
