    So i have taken the carriage apart and cleaned & inspected everything! i have leveled the parallel tracks with a builders laser level What i have found is the gantry has a slight twist ,so if you reset the bearing height on gantry to .120 inch in the 4 places shown in the tutorial one of the bearings will have less pressure than the other 3. I do not know why there is a twist but i [have compensated] to have equal pressure. Along with this adjustment i have cleaned the bearings [ one has deterioration on the rolling surface ] and will replace in the future. I did find dirt & residue in behind the torch lead screw,where it rolls on the rail. I find the table to be more precise in the cuts as well a much smother motion [ less jerking ] now!

    Here is the alignment guide for the rails. Which falls in-line with setting the height of the gantry according to the alignment of the holes on the aluminum L bracket.
