Very Simple Hardware

A simple laser SCARA:

It uses 50mmx25mmx3mm aluminum bracket.

The main downsides are:

• direct drive (with micro-stepping)
• single motor axles
• canter-lever design.

Still it should be useful for testing.

Reworked the design

Reworked the design away from 50mm x 25mm 3mm aluminum angle.

Here is a 6mm MDF design:

And the laser cutout (300mmx300mmx6mm MDF sheet):

The bending moment calculations suggest less than 0.5mm deflection (assumes 2.5N end load). Maximum end load is 30N (~5mm deflection).

I sent the design away to be cut by a professional laser cutting company.
