klipper-extended-corexy-kinematic VS EnragedRabbitProject

I would use this new core xy structure. That massive of a gantry will need a lot of help moving https://github.com/SnakeOilXY/klipper-extended-corexy-kinematic/blob/master/doc/kinematic.md

Maybe read the docs: https://github.com/EtteGit/EnragedRabbitProject/tree/main/Documentation

EnragedRabbitProject

Personally, I've almost driven myself nuts in getting ClockWork2 to work reliably ever since it was made public but was never satisfied due to it seemingly not coping well with the increased friction coming from my use of an ERCF as part of my System.

For single extruder multi-material like the Prusa MMU, there is the Enraged Rabbit Carrot Feeder: https://github.com/EtteGit/EnragedRabbitProject

I'm not entirely sure on that either. The Enraged Rabbit Carrot feeder seems to have almost all of the AMU's secret sauce (with the exception of the single multispool drive unit on the ERCF vs the AMU's multiple independent ones). In all honesty if Bambu was going down this route I would have preferred they leaned in on their proprietary motor control hardware (h-bridge and in house firmware) vs the industry standard TMC derived controller hardware. I think that the situation of having 20+ of the worlds 26 3d printer companies within the same metro area in a country that has the most loosy goosey state industrial/disaster capitalism model in human history is going to get us (in our corner of the world) in some serious s^$#.

You should print the calibration part here : https://github.com/EtteGit/EnragedRabbitProject/blob/main/Carrot_Feeder/Stls/Tools/Calib_Test.stl

https://github.com/EtteGit/EnragedRabbitProject/blob/no_toolhead_sensor/Documentation/ERCF_Manual.pdf page 116 shows the correct configuration for SuperSlicer. What slicer are you using?

Owning both I'd say there's no reason to be concerned about reliability being an issue - At least not without also incorporating an ERCF into the Mix which may give some frustrations at times ( I highly recommend going with the Happy Hare Software Suite instead of the default one ).
