That E3d Tool Changer kit looks neat, but the issue I potentially see is heatup time - if the parked heads get shut down, I would think the time required to get to temp could potentially be an issue.Unless they were brought to temp before the carriage went to switch, but that wouldn't work too good if they go to the pogo pin connections I saw mentioned in a video.

After a year of printing with the CBot kit I got last year, I decided I want to build my own, larger printer. What I'm building is going to be similar in design to a Flying Bear P902, just bigger.
I have a good idea what I want to do with the Z-axis, but the X & Y axis is where I'm floundering a bit. I was originally thinking of using linear rods, at least 8mm, for all. I had been thinking of using two rods on either side for the Y axis, but that may be overkill and one on each side would probably be plenty, but then I was considering linear rails. For the X Axis, I'm thinking of something like the Flying bear, where the rods sit side by side and the print head drops down in between them.

Flyingbear p902 has huge bed cantalever
they even dicontinued it with p905 that supports bed on two ends
Consider linear rails

a lot of good build techniques there

How big is bigger? If you have large spans, 8mm round rods have low moment of inertia, or resistance to bowing, compared to 2020 extrusion. Almost all larger machines use extrusion of some sort for the XY, with the extrusion as the rail, or ground linear rails on top of the extrusion.
