    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.

    when you factor in that my machine will be all steel built, have supported rails, the right steppers/psu as advised via this forum a cutting area of around 500x550 with a 2.2kw spindle and it's going to cost under 1k i'd say it's very likely you would certainly do well to follow deans advice.

    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
