Good luck with the build.
hi, no i was thinking of using one rail on the top and one one of the bottom, tho im going to redesign the z axis so that the motor is not so high up, possibly mount it on the other side of the alu profile, offset the weight a bit. im also thinking of keeping the linear bearings fixed and letting the rails move up and down on the z axis instead, this should keep 250mm of 12mm aluminium sheet fairly rigid.

Its hard designing things , might just order lots of bits and make it up as i go haha
