Hi All - Due to the C-19 virus the place I usually go to today is shut down so I'm beavering on Brevis again. I hit a speed bump with Z axis width. The combination of flaring allowance and flanged bearings made the z axis quite wide. So I had to rejig the design to square bearings. I usually use flanged as they provide a bigger base for bolting to. The other element in the mix was using a std nut housing vs making one which is cheaper. So now after a bit of rework here it is again. I found downloading the Hiwin models very easy. They certainly provide great info and support. Now I can get back to the saddle. Cheers Peter
