It looks like we don't have to reset the whole ToolChange state machine when resolving an error with the middle button (Retry) - but jump straight into the feeding phase. The reasons are multiple: - If an error happens during the unload phase, it is handled separately in the UnloadFilament state machine - If an error happens during the feeding phase, the unload has been already successfully completed. And when restarted from the very beginning, the ToolChange does the last retract sequence from the UnloadFilament phase -> that is not healthy, because the filament gets pushed away from the Pulley and causes another error. |

Prusa-Firmware-MMU-Private
How to prepare build env and tools
As the first step extract the AVR-GCC to some dir, e.g. /home/user/AVRToolchainMMU/avr8-gnu-toolchain-5.4.0
Add /home/user/AVRToolchainMMU/avr8-gnu-toolchain-5.4.0/bin to your PATH.
mkdir .dependencies
cd .dependencies
mkdir gcc-avr-5.4.0
cd ..
utils/bootstrap.py
bootstrap.py will now download all the "missing" dependencies into the .dependencies folder:
- clang-format-9.0.0-noext
- cmake-3.15.5
- ninja-1.9.0
Note: bootstrap.py will not try to download the AVR-GCC as there is already a directory called
gcc-avr-5.4.0. This will be fixed when we find out where to download the correct packages reliably.
How to build the preliminary project so far:
Now the process is the same as in the Buddy Firmware:
utils/build.py
builds the firmware.hex in build/mmu_release
In case you'd like to build the project directly via cmake you can use an approach like this:
mkdir build
cd build
cmake .. -G Ninja -DCMAKE_TOOLCHAIN_FILE=../cmake/AnyAvrGcc.cmake
ninja
Should produce a firmware.hex file as well.
