What is the size of this machine?

It is a 2x4' machine. Other thought was to use the existing threaded holes to mount 80/20 extrusion and then mount the rails to that. That would definitely give enough adjustment. Or maybe drag it behind my truck town the highway.

80/20 has wiggle room, but it may be iffy to get 3/16 - 1/8" adjustment from 80/20 mounted on each side (3/32 - 1/16" per side). I use a lot of 80/20, and am just completing a new build with it.

If you saw my build thread for a 4 x 4 Saturn 2, you saw that mine was defective in about every way. Fortunately, when if first opened the box, I saw the in washer between the gantry mounting and interface plates. I knew something was very wrong. That led me to check everything right away, and found out how bad things really were. Fortunately, I acted quickly enough and was able to send the machine back for a full refund.

Something else to consider. Will you have enough Z axis movement, if you raise the gantry height with the 80/20? I didn't get my Saturn 2 set up (I had it on end on a large dolly), so I didn't check Z axis travel. I looked at some possible fixes (I really like the idea of a welded frame), but abandoned the idea in favor of sending it back. Way too much wrong with the machine.

You should also check to make sure the two side rails are in the same plane. I'd be surprised if they are. If there is a twist, 80/20 won't help you with that. Also, look at the steel tubes for square. If they aren't square, it may be impossible to get the profile rail properly aligned. The very best repair solution would be to have steel plates welded to the frame and have the frame stress relieved. Then find someone to mill/grind the on plates flat and mill reference edges for the linear rails. Finally, get new mounting holes drilled and tapped. I didn't get so far as getting the work quoted, but it has to be expensive.

I feel for you Erik. It's terrible to drop all that money on a machine that isn't even close to what's advertised, or nowhere close to being fit for its intended purpose.
