Well I have finally started to build my router. The plan is for it to cut wood and aluminium. Here is a parts run down for the different axis:
X axis:
6 x 300mm 12mm THK rails with 6 x carridges
2 x 400 Oz/in Nema 34 steppers
1 x 800mm 25mm balscrew with two nuts
Y axis:
2 x 520mm 12mm THK rails with 4 x carridges
1 x 380 Oz/in Nema 34 stepper
1 x 350mm 25mm ballscrew with 2 x nuts
Z axis:
2 x 200mm 9mm THK rails with 4 x carridges
1 x 250 Oz/in Nema stepper
1 x 150mm 16mm Ballscrew with 1 x nut
The main frame work wil be completed using 44mm aluminium box section 3.2mm wall thickness.
