As I get used to the toolchanger, I realize I want to go vertical, and I'm looking for any advice or experience. I've currently got a bowden Hemera (mounted on top of the back, with filament path behind the printer), and a direct drive hemera also with filament behind. The filament spools sit on rollers on the table behind the printer. This has several downsides: Filament is behind, relatively hard to access, swap/load/unload The printer is deep already (~20+ inches") and adding filament behind makes for a big footprint Long curvy filament path adds friction/slop (more critical for the bowden, but still a factor for direct) My plan is to build a sturdy shelf (roof) 12-18" above the TC (integrated with a table I just built). The wires to the TC will come down from just in front of the center of the bed, enough slack to hit all four corners comfortably. The wires/filament for each tool will come down from just forward of their respective docks. With that, I think I should have shorter and more direct paths for everything, and less (zero?) collision between the various cable bundles). I've got to build the 'roof' first (part of a longer term full enclosure) and start visualizing/testing the paths. Has anybody tried something along these lines? Long term this will be part of a full enclosure, electronics and filament outside. I'll use the sides/back of the printer, cover the bottom, add this roof on top, and some type of front door system (preferably clear). I'll be busy for a while... Any thoughts on this approach?
