I am pleased to announce the first beta release of RepRapFirmware with a Real Time Operating System kernel. RRF 2.0 uses FreeRTOS, a light weight RTOS kernel coded to high integrity standards that is ideal for embedded firmware running on 32-bit processors.
The use of RTOS will speed up future development of RepRapFirmware and facilitate advance features. In future I hope to implement even faster file uploads over the network to the SD card, simultaneous file uploading and printing, automatic simulation of print files in the background, automatic tool preparation in advance of a tool change, and more.
A pre-built binary of RepRapFirmware 2.0 beta 1 for the Duet Ethernet and Duet WiFi is available via [
github.com]. As always with GitHub, follow the links until you reach a page with a Download button.
