Hello, I remember , that somewhere the author of this design wrote, that he was modified the Y axes side plates adding second anti-Backlash nut block. But according the photo in store, I saw that the side plate is still made just with 1 anti-backlash nut block. So the questions to Openbuilds are: 1. Do You consider, that second anti-backlash nut block is completely unnecessary in terms of high precision and repeatability with zero play or slop? 2. May be the photo does not introduce the real situation and in reality the side plate is with 2 blocks? Thank You in advance.
I may be wrong, but if I am correct, couple years ago, used to be two seperate configurations that were popular 2 x regular nut block (not anti backlash) spaced on the plates near the edges, and you effectively pushed them away/towards each other before tightening to the plate, to take up the slack and eliminate backlash or 1 x anti-backlash nut (effectively has the built-in second-nut inside the flexture of the nut itself), and you take up the slack by adjusting the grubscrew then lock it in place with locknut. Easier than the older option The 2x nut block config did help a little with whipping by supporting the screw a little more rigidly, so might still be a good modification to do, but not a necessary one for eliminating backlash
I am talking about this configuration It was the second version of Kyo's Sphinx with 2 anti-backlash nuts. Why not to drill just 4 additional holes and leave the choice to the builder use 1 or 2 blocks. It is so easy , and I believe that 2 anti- backlash blocks in pair work excellent not only in the case of Y axes side plate, but also on the X axes.
