Hi this is my first post here in the forum, and i'm glad of share whith all you guys; after 5 months since i recived my machine, last week i started to put it together. today i went through some difficulties with the gantry car ( y-z )and the rails. i notice that when i was setting the bottom weels on the y-z car they rolled perfectly on the center but on the sides they do not, when i tried to fix that problem adjusting the concentric nut, the car got stiff on the center. after many thoughts and head scrathes i just put my level on top of the car, most exactly on the V rail and oh surprise it is bend.
on top for about 3/32 of an inch on the sides and on the bottom for about a good 1/8 on the sides too.
same thing i notice with the x rails they are bend with both ends upwards, the gap on the center of the rails is 1/16 of an inch, the table is at perfect level and parallel, maybe thats why the motors rotate smothly on the center and harder on the sides?
any suggestions/comments,are very welcome
i'm sorry for my way of writing, i know i'm not very good i'm just learning, thanks
