Looking good, smooth sailing so far. As for the center……keep everything super loose, only tighten it when you have it on the machine and the cross bars are snugged up in place. seems to keep things a bit more, square.
I’ll check the assembly page now. Sorry about the 2.5’s, sound like crappy engineering….I made so many version of that part with the bearings in different configurations I got tired of waiting for it to print so it never really got any finalizations.
Yup no support on anything other than the rigid middle z. Although I get as good of support with cura now as I do with simplify 3D. I always set a 1layer gap, and the support density plays a big part 2mm apart seems good usually, and about .7-1mm from the x and y.
