    you can add a side panel with tube supports and drill thru the tube and mount the tubes to the wall so there is no flex as show in these pics:
    sorry they are a bit big..

    Jpike, I really like your support for the X rails. I was going to modify my plans for the JGRO and mount the pipe rails for the X axis directly on the base but that left the gantry unstable. Your brackets will allow me to build it from plans and just add the supports that you used. Very nice indeed.

    Could you list your choice for motors and lead screws. I have the Gecko 540 on the way and want to use motors that will provide reasonable speed and torque.

    I was thinking of ordering the G723-280-4 or G723-400-4 280 oz in or the 400 oz in NEMA 23 motors from Gecko. I am not sure of which lead screw to use but was thinking of the 1/2 -10 ACME 2 Start. I would welcome all opinions. I would like to use the same lead screw on all 3 axis.

    Thanks in advance, JR

    You need to keep in mind that the rails have adjustment blocks where this style of support is static. You should design some sort of adjustment capability in the supports as well.

    I think it's generally agreed that 380oz motors are the best match for the g540

    If you are going with 1/2" -10 acme then 5-start is what you want even for the z.

    Thank you. The adjustable mounting for the added rail support is on my list.
    I think I should go with the G723 400 oz in motors from Gecko.

    If I use the 5 start ACME lead screw will it load the steppers a lot more than the 2 start?
    I figured the 5 start would provide faster axis motion but at a cost of higher loading on the motors.
