Sure is agricultural! :clap:

I'm looking at your X axis drive arrangement and wonder if the z carridge will bind in the rails. You have a turning moment there with the screw at the top and the cutter at the bottom, the point of rotation will be somewhere in between the X rails.

When I redid my rockcliff in alu angle I had a load of trouble with bearing blocks binding with the smallest possible movement in the assy. I still have trouble with the Y axis table (fixed gantry version) when I remove the upper part of my table with the T slots in.

I think you might have a problem with all that space between the uprights of the Z carridge letting the assy flex. To prevent that, you might want to make a bracing plate to stiffen up the four corners of the rectangle formed by the bearing blocks. And while you're at it, put the X drive nut in there too.

Any way. Thanks for reading my 2 cents worth. I hope it isn't needed. :whistling:
