Month or two, depending how much time I can use on it. I'm planning on mostly printable, yes. Metal z rods are an option if things don't work out well...

Well I've already built 1/3 of the new one and also written it down in the forum posts so I very much intend to finish :)

No support for firmware retractions. Linear advance is supported. Marlin's tool change configuration should be disabled when using this script

That's good alternative too. I'll have a look about that.

Pre-move retractions are applied before moving to the tower. You can check this from the gcode, look for line ; TOOL CHANGE, there should be retraction before that line.

Filaswitch follows the retraction settings of the sliced gcode so make sure you have the wanted retraction enabled for the extruders
