|+||In [[8-mill-something|Step 8]] we found some backlash and reduced it by tightening the end nuts, but that's not a perfect solution - too tight and the nuts bind up as the shaft spins, too loose and the thing comes undone again!|
|+||So, I bought some M6 half-nuts (left-hand thread for the Y axis, normal for the X axis) to allow me to take the play out and then lock the nut in place.|
|+||I haven't fitted them yet, I am hoping to also make some new end-plates ([[http://www.jarkman.co.uk/catalog/cnc/russmf70.htm|like this guy]]) with deep groove bearings to improve matters further.|
