Deflection in precision rod rails

[irving2008]

:rofl:

Pretty bendy stuff but average joe probably wouldn't be bothered (or know to be)

I'm surprised how rigid that stuff actually is...

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 think 20mm is prob required for a lightweight ali miller on X and Y with 16mm on Z

Fully supported rail with open bearings is best but harder to work with...
