Happy Hare support #1

Open moggieuk opened 2 months ago

Happy Hare support is quite easy but needs me to finish a few details to make it work -- mainly around tolerating lack of some configuration. Already no selector is required, etc. Just need some free time, but this will be done soon.

Other than use of servo for "selector" rather than stepper motor, don't you need the opposite extruder direction for the second tool?

How did I miss this! Sorry!

Other than use of servo for "selector" rather than stepper motor, don't you need the opposite extruder direction for the second tool? Yes exactly! The Motor has to spin the other way around for feeding Filament B compared to Filament A. Don't as me why, but in my code that happened somewhat on it's own. I added a variable to invert the extruder direction, but without using it, Klipper does it automatically.
