Floating Extruder looks to me the best fit for MultiBot:
For movements in the Y direction the extruder does not have to be accelerated, for long travel along X the bowden absorbs forces and lets the gantry go smoother
The bowden tube itself becomes shorter what is better
Direct drive in my opinion may be necessary for extruding flexible filaments: how often we need to print huge flexible items?
Do you agree I go on with “floating extruder” or you have better options?
Begining of April those discussions I can do on https://multibot-3d-printer.blogspot.com/
