Double gantry idea, What do you guys think?

[D.C.]

If you make a double gantry aren't you going to need a new Z-block anyway, otherwise how is the z-axis assembly going to be attached to the second axis?

Think DC is right & you would be far better beefing up the almost non existent gantry. You can't change the Y axis to supported rail without affecting the Z axis as the bearings at present are in the same block as a major part of the z axis. Not sure a double gantry is the way to go & probably at least as much work as sorting this gantry properly. Don't have the experience to comment on the double gantry but guessing the idea came from the machine that was discussed on here not so long ago.

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?

[wilfy]

i think it bends as the machine looks like it's made from cheese :D
