Re: CNC macro rail

Hope that used guide rods not to bend on load. The length is 500 mm and diameter is 16 mm, induction hardened (62HRC). It is not lightweight construction. It is more like a tank. But small weight is far to the top of important parameters this time. The most important parameter in this my "DIY CNC rail project" is ultimate precision. Precision goes together with nonbending/robust solution after load by attaching camera and other parts.

Now i tried to load it by my weight (about 85 kg) and it was still moving without trouble.

No way to bend it via more than twenty times lighter real equipment.

The second hyperlink looks good but two parameters miss the target:

- Datasheet say 100mm max stroke. It is four times less than this axes needs

- Positional accuracy about 0.1 mm - my expectations are with precision at least ten times better.
