Modular cnc. Part 5 (first tests)

I've made first coupler based on 1,75mm filament. I've placed 6 pieces of 3cm long sticks. It's work like a charm. Intentionally moved motor about 1mm lower than main axis (you can see this on photo below) and it's working great :) 

Here you can watch how its working. 

In whole project I've made many corrections, mainly splitted moving part to two separated. Little changes in side holders. And the new coupler. In next parts - I'll present few types of machines which can be done with those modules. 

Edit:
Axis test with some load.
