Hi, thanks for the comments, the bearing blocks have four screws in each two you cannot see until you look at the back, have been working on the assumption that Z axis load will be only light up /down movement therefore single bearings with thrust bearing each end, loading should be taken on the Z axis linear rails and blocks.
re: the width of the Z axis this is fixed at 215 mm wide, if you look at the vid of the machine before I purchased it, it cuts to the max width of the moving table, so no point in changing to a lesser width would not gain anymore cutting area only lose some rigidity.
I am planning on using a small Elu router not the dremel, for more cutting power, selective cutting speeds, greater range of cutter profiles, to cut wood, metal, plastics, and I will be fitting a diamond drag point for fine engraving.
One thing I am not clued up on is the electrics, I have used 4 core shielded cable for the motors, I have 2 core shielded cable to use on the limits, but not sure how to lay these out, do I set them to the max travel of each axis, or have one end adjustable to use as a Home limit?
Your point of the false trip outs would adding more shielding to the cable as it crosses to the BOB help? as I don't have any more space to get in.
