Firmware Names

Issues and Support

There is a bug in earlier versions of RRF that will prevent mainboards operating in CAN expansion mode from being upgraded over CAN. The simple solution is to remove the SD card and copy the new firmware to firmware.bin. This bug is only present if upgrading from a version of RRF lower than 3.5.0-rc.4.

Please report problems/ask questions using our Discord server (see the Wiki for details).

Important information about this release

Due to a bug that has been identified with this release, we have decided to withdraw RC4 until the issue has been resolved. If you are already running RC4, there is nothing to worry about as long as you have taken the steps described below.

If you use a M400 command in your deployprobe.g or retractprobe.g file (or the corresponding files with the probe number added e.g. deployprobe0.g) or in any macro files that are called by those files, and your main board supports multiple motion systems (e.g. any Duet 3 main board or STM32 board), you must add parameter S1 to that command. Failure to do so is likely to result in head movement outside the configured M208 limits.

Adding the S1 parameter to M400 commands has no effect if you are running older firmware versions, so you won't need to remove it if you subsequently revert to an earlier firmware version.

All Users

This release of the firmware removes the use of legacy entries in the board.txt file. The following tags are no longer used:

• lpc.board= use board= instead
• softwareSPI.pins= use one of SPI3.pins=, SPI4.pins=, SPI5.pins= instead
• sbc.lpcTfrReadyPin= use sbc.TfrReadyPin= instead
• adc.prefilter.enable= is no longer needed

This releases adds the ability to control LEDs attached to expansion boards. As part of this feature changes to how local LEDs are configured and controlled have been made. Pins must now be defined using the M950 E option (see: M950) minor changes have also been made to how colours are set using the M150 command (See: M150).

WiFi Users

As well as updating the firmware, you need to update the following:

• ESP8266 and ESP32 firmware V1.27-01 (or later) from here. Instructions for STM32 ESP8266 are here and STM32 ESP32 are here
• DWC inline with the firmware version from here.
• This release includes version 2.1beta6 WiFi firmware. This is required for the new RRF MQTT feature. The files for this preview are included alongside the standard RRF firmware files (see DuetWiFiServer.bin for ESP8266 modules and DuetWiFiServer_32.bin for ESP32 based modules) .

SBC Users

As of this release upgrading the SBC version of the firmware requires the use of an additional RAM based program (stm32f4_iap_SBC.bin for the STM32F4 version). The easy way to ensure that this is correctly installed is to upload the .zip file version of the SBC firmware to the system folder using DWC. This contains the required firmware components. If this additional component is not installed you will not be able to easily update to future versions of the SBC firmware.

Please follow the instructions from here

Upgrade Information

New Plugin

There is now a new plugin (releaseMgr) which will help you check for updates. You can also view the release notes and be warned of any config changes required. You can find it here

All Users

This release of the firmware removes the use of legacy entries in the board.txt file. The following tags are no longer used:

• lpc.board= use board= instead
• softwareSPI.pins= use one of SPI3.pins=, SPI4.pins=, SPI5.pins= instead
• sbc.lpcTfrReadyPin= use sbc.TfrReadyPin= instead
• adc.prefilter.enable= is no longer needed

This releases adds the ability to control LEDs attached to expansion boards. As part of this feature changes to how local LEDs are configured and controlled have been made. Pins must now be defined using the M950 E option (see: M950) minor changes have also been made to how colours are set using the M150 command (See: M150).

WiFi Users

As well as updating the firmware, you need to update the following:

• ESP8266 and ESP32 firmware V1.27-01 (or later) from here. Instructions for STM32 ESP8266 are here and STM32 ESP32 are here
• DWC inline with the firmware version from here.
• This release includes version 2.1beta4 WiFi firmware. This is required for the new RRF MQTT feature. The files for this preview are included alongside the standard RRF firmware files (see DuetWiFiServer.bin for ESP8266 modules and DuetWiFiServer_32.bin for ESP32 based modules) .

SBC Users

As of this release upgrading the SBC version of the firmware requires the use of an additional RAM based program (stm32f4_iap_SBC.bin for the STM32F4 version). The easy way to ensure that this is correctly installed is to upload the .zip file version of the SBC firmware to the system folder using DWC. This contains the required firmware components. If this additional component is not installed you will not be able to easily update to future versions of the SBC firmware.

There is currently no support for SBC mode when running on STM32H7 based boards. It is intended to provide this support in a later release.

Please follow the instructions from here
