mounting profile rail - Hiwin Manual vs. typical approach

[dsc]

Just a quick question again on the linear rail installation. Hiwin manual shows this:



So master rail bolted, three linear blocks bolted to the axis plate and moving the thing up / down, bolting the second rail at the same time to make sure it's all parallel. This assumes that the two left-hand side linear blocks on the axis plate are in the same line ie. same distance from the edge and the third one is on a line parallel to those.

I have the master rail bolted down and it's pretty much parallel to the edge (within 0.005mm). I also have one block on the master side bolted and it's also cock on parallel to the axis plate (within 0.002mm). Is it a good idea to loosely mount the second linear block on the master side, slide [both blocks + axis plate] on the master rail and then bolt down the second linear block to make sure both blocks are on the same line / parallel? The whole process would go like this:



This means effectively using the master rail as a reference line, according to which two linear blocks are set in the same line.
