D3D @ Fontys Sittard
This edition of the D3D was made in the town of Sittard, the Netherlands in a pilot project for a course for STEAM teachers. We intend to spread OSE as an educational context to schools in the region, starting with this printer. Everybody who graduates as a STEAM teacher will be able to build one.
Frame
The frame was made using cold rolled steel profile instead of sheet metal. We had them made in metal workshop of a school we know and they had these profiles lying around. The paint was chosen by students. Maybe I will add a few silver swirls or a zebra print to it later.
Wiring
At first none of the axes worked. We found it is quite easy to troubleshoot if you just connect a loose stepper to the relevant driver and see if you can get it moving through pronterface. The D3D Controller page says it is essential to rewire the stepper cables. For us this somehow didn't work, so we had to rewire the cables to their original configuration. Steppers are stepping now, though sometimes in the wrong direction. Hoping to fix that in the firmware.
The LCD-display doesn't work yet. Maybe it's because it is a cheap Chinese clone.
