Rain under bed

Undoubtedly it is easier to bolt the rails to the underside of the Eco-cast bed as you have done.

The only potential downside is that you are at the mercy of how straight the rail is and they do tend to have a small amount of bend to them along any significant length like that axis will have... might be worth thinking about how you will go about making sure it is running straight and true when bolted down since you don't have a reference edge to butt up against, even if it is as simple as running a piece of fishing line taught alongside and then eyeballing it straight as you bolt it down. Once you've done the master rail the other one should be able to be floated in to place.

No different to how a significant number of machines on this forum are built though in essence, just instead of epoxy level you are using eco-cast for level and mounting upside down. I quite like the way you've done it with the small mount pieces giving you a level of adjustment for gantry width there too - something mine will be much more sensitive to.

Will you be posting a build log?
