Tunnelplan 3D printer

At a print length of 500 mm I need more support.
So I used a 10x2 mm carbon tube to support the two aluminium tubes.
You get a lot of stiffness with this triangle of tubes.

I improved the hotend/ extruder support.
The two Z stepper motors are connected with one belt.

The carbon tubes inside the aluminium tubes gave a lot of extra stiffness.
Waiting now for a 3D Touch autoleveling sensor.

Changed the extruder/hotend drive and turned it 90 degree for more stability.
Use 6 mm wooden rods inside the aluminium tubes, that gave more stability.
Ordered 6/4mm x 500 mm carbon tubes from China for replacement wooden rods.
