You way is better Dean but I have thought about this... the bolts which connect the end plates to the plates on the x rail bearings can be loosened and shimmed... not as easy but hopefully possible!?

In your case then yes Joe about the only thing you can do. But this just highlights another less than ideal situation with this approach.?
The gantry isn't bolted into the bearing plates and completely relying on the end plates to stop twist etc. Also not being securely bolted to the plates leaves gaps which can vibrate and introduce place for resonance.

Adjust is important but equaly so is being securely bolted and secured. Having one doesn't mean can't have the other just requires some careful thought and planning.

Joe please don't stress too much over this. My comments where more to help others avoid similair issues and not to pull you down or have you start with major redesign etc.

Now you have it done this way then I'd suck it and see. If the gantry is long way from square then you may need to do some shimming. Anything you can do to make sure Y axis is 90Deg to X axis the better. Try to avoid using the screws to square the gantry as it will put binding on the bearings etc.

Thanks Dean, I figured I would suck it and see just wanted to talk though the options if needed...
