Well another build update:
Got my profile rails (as said before in earlier reply) but also ordered 1610 ballscrews for all the axis.
Spent some time in the garage tonight and got the y axis rails mounted and spaced correctly. They run relatively smooth, a little tougher than expected but not in a bind. Im thinking that the stiffness is caused by slight misalignment in the level of the trucks relative to each other. I will see when i get the actual gantry on there and all bolted up, might need to be slightly shimmed. Anyways, ill post more when i get some done. I am trying to get some more time on this to get it done, but life always seems to happen. Thanks.
