DC these 3040's call the long Axis Y axis and Z axis is attached to X axis.!!
Craig the X axis block could easily be modified to accept open bearings then beef up the gantry with a strong plate and then drill and support the rails from behind.
This along with supported rails on the Y axis should help greatly and not cost a fortune.
Other than that then I wouldn't bother and sell the whole thing and build a far stronger machine from scratch.
Thanks for all the advice, Would adding supported rails really be sufficient enough to stop the leaning back?
Have a merry Xmas all too!
Are you sure the problem is the rails bending and not the bearings being poor tolerance?
i think it bends as the machine looks like it's made from cheese :D
