Avoid the Pitfalls: Prusa XL semi assembled build tricks

This is the video I would have liked to have seen before building my Prusa XL. Not hours of tinkering, just an overview of the build process and comments on parts that might be tricky.
One note, I think Chrome might work best for the belt tuning app.

I own a 5T XL, great video. For something so important, secure tool head dock mounting for the tool changer, Prusa sure made it a weak point - hard to reach and a small screw. My docks have come loose after a lot of printing, but if it happens again I'm gonna follow what you did and take that plastic piece off to get the short end of the hex wrench on it(and use thread locker). Honestly, Prusa should update the guide to that way, something so critical needs to be torqued as much as possible, but they probably want setup to seem "fast".

Very nice video and full of important info!

Thanks for all the great info. I'm curious about your drybox system for the spools on the side. I don't think I have the room for it. I was thinking of mounting the dryboxes above the printer, but then the filament path will not be correct.

They are cake boxes I found in a superstore I had access to. I settled on these after a bunch of trials on boxes that were big enough, turns out that the average sealed lid plastic box will not actually keep silica gel dry in a humid environment. I've now built the EnXLosure and find sadly that I can't fit more than two boxes on a side, so will be investigating a cereal storage box solution.
