Deflection in precision rod rails

[Lee Roberts]

12mm probably good enough for a PCB miller on the X-axis supporting the table, with 16mm on the Y axis and 12mm on Z.

I'm about to start work on a mill i plan to use for PCB's and 12mm rail was the choice, i have rail to hand and so i can use other sizes at what point would we not see any deflection, with this info i could work out if the weights i plan to move would be a problem on 12mm rails ;-) keep up the good work !
