 +==== Extrusion Fan ==== 
  
-==== Setup Bed ====+For bridges an extrusion fan is mandatory. All frame based solution didn't cool the filament in all dimensions. Depending on the object the result isn't as expected. Therefor I changed to a radial fan mounted on X-Carriage. 
 +The solution is described on [[http://www.thingiverse.com/thing:927030|Thingiverse]].

 +==== Melzi PCB Holder ====
 +
 +In order to get for print area (Z dimension) I positioned the PCB in top. The original printed PCB holder (4pcs.) ate reused. The PCB is mounted on a laser-cutter 1.5mm thick [[http://www.kraftplex.com/kraftplex/|Kraftplex]].
