What is your backlash of your Patriot?
I'd like to try and improve this on my machine. Especially the X axis at the moment. All I have done is tighten the threaded collar clamp and snug up the gibbs. This really helped the Y axis being at .0128 but there was not much gain in this for the X axis starting at .0146.
As it stands I have the following backlash.
X .0135
Y .0048
Z .0034
