Altmill 4x4 orientatoin of cross beams

Other than not having a smooth front surface, is there any reason not to pit the first crossbar in with the flange facing forward?

I want to mount a 2020 extrusion under the first section. T-slot on 2nd beam makes it easy to connect to, but because they only have slots on one side mounting to the first beam is harder.

The legs attach to t-slots that are only in the non-flange face.

Thanks! My kit has been shipped, but hasn’t arrived yet. Going to have to come up with some kind of bracket I guess.

Sure wish they had put a t-slot on both sides of the cross-beams.

It’s like they read my mind. Just received my altmill 4x4 and the crossroads now have a t-slot on both sides!

And underneath also! Handy.

The underneath thing is not a T slot.

Yep, I see that now.

they should have done same t-track underneath as well. kind of a miss on their part

The bottom groove is where the screw goes to connect the cross beam to the rails.
