- WiFi users will need updated ESP8266 firmware V1.25 please see: https://github.com/gloomyandy/DuetWiFiSocketServer/releases/tag/V1.25-01
- SBC users will need to update the SBC software to V3.2. For STM users see https://teamgloomy.github.io/stm32_sbc.html for LPC users see: https://teamgloomy.github.io/lpc_sbc.html
LPC users need to ensure that the following changes are made to the dsf config.json file:
"SpiTransferMode": 3
"SpiBufferSize": 3072
"MaxCodeBufferSize": 200
"MaxMessageLength": 2560
NOTE: In this version of the firmware the default operating mode for TMC22xx drivers has changed from Spreadcycle to Stealthchop to match the documentation and Duet3D settings. This means that if you previously had no explicit "D" setting on M569 commands you will need to add D2 to have the same settings as before.
