Upgrading my z axis to metal vwheels from open rail.
Very nice where did you get those metal V-wheels? I have been lately looking at ways to improve the rigidness of the Z-axis… especially when using 0.3mm - 0.5mm end-mills the spindle vibration and the lack of rigidness on the Z-axis equals lots of broken end-mills

I order mine, in back order :’(… getting 8 so the Z-axis and also the front side of the X-axis, I seen some play there too when a wide tool say a wide drill bit starts penetrating the material at work.
