Dual X Makerslide > how can i compensate imprecise cut?

Post by typomaniac » Sun Sep 27, 2015 8:55 am

Hey,

i am just in the process of resizing my eshapeoko with a dual-x axis. The 2 makerslides are bolt together and i can see that they were not cut with high precision. There is a slight angle which results in the rear maker slide being a mm short on the top compared to the bottom. Same goes for the left side. I wonder what would be the best solution: Putting Washers between the plates and the slide until i get a right angle or taking a miter saw and sacrifize 5 mm of the maker slide by making a new cut with the bolt together rails.

Thank you!

P.S: After making the bolts i also recognized that both rails are not perfectly parallel. The rear rails has a small offset on one side of about 0.3 mm. Do you think this will be a problem?

Use aluminum shims. A mix of heavy and light aluminum foil will work

When bolting the rails in place, my suggestion would be to leave the out-of-square corner loose, reinforce the other edge w/ angle brackets and clamps, put a clamp on it (w/ cauls) and pull it into square before tightening.
