Base structure
TIP: Bosch-Rexroth extrusions profile are usually sold in bars of length 5600 mm. You need one bar and half for one HackerBot, about 8.5 meters.
To optimize bars cutting, our advice is to divide the whole bar in two parts, with length 2700 mm and 2850 mm.
From these three bars you can cut the structure profiles:
- 2700 mm bar: n.3 600mm and n.2 450mm
- 2700 mm bar: n.6 450mm
- 2850 mm bar: n.1 600mm and n.5 450mm
