I’m looking at my garage and realizing I don’t really have the space to set this up horizontally, but I have an unfinished garage with exposed 2x10 beams, making it perfect for mounting vertically. This will of course change the load distribution quite a bit, with most of the weight on the top and bottom conduit rails. I’m thinking I could drill into the bottoms of them to add a few threaded rods, which I can then more fully support from below. It seems like I might even end up with less flex this way, since the vertical gantry rail would completely support the center piece.
On my kossel I mounted counterweights on pulleys to offset the weight of the flying extruder (basically an extruder mounted above the effector that’s tied to the carriages, allowing for an ultra-short bowden). It’s a bit crude, but it didn’t appear to hurt the print quality. I’m wondering if just a pulley+counterweight mounted to the ceiling would do the trick…
I’m using a keychain retractor for my flying extruder. I had 3 but it was a little overkill, one seems to work. I had a pulley system with a counterweight, but it would start to do the pendulum thing and cause layer height funkyness.
Counterweights would probably work. One off each side bearing.
