D.R.racer 37f820e9a6 Prevent filament creep in activeSlot+1 
This PR is just about tuning the intermediate Idler positions so that the filament gets relieved from the Pulley safely while the Extruder gears take over and the activeSlot+1 filament is not affected by its Idler bearing.
On a test bench filament was creeping about 0.5mm per Toolchange.
Changing the intermediate position from exact middle into 3/4 practically elliminated the creep. We can play with these constants more if necessary in the future.

How to prepare build env and tools

Run ./utils/bootstrap.py

bootstrap.py will now download all the "missing" dependencies into the .dependencies folder:

  • clang-format-9.0.0-noext
  • cmake-3.22.5
  • ninja-1.10.2
  • avr-gcc-7.3.0

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/AvrGcc.cmake
ninja

It will produce a MMU2SR_<version>.hex file.
