after some months without my reprap prusa i start to doing new test. My Friends Simone told me interesting firmware for manage my 3D printer .
The name of Software is Repetier-Hosts this is the link :
The big advantages of this firmware respect of other tested some month ago is that this is an integrated development suite.
In one Software there is 3D visualization , support for Slic3r or Skinforce , and managment of printer.
So you have 1 enviroment that support also the simulation , so you can see before to print what could be the result of your printing using the Virtual Printer driver.
Now i found a nice Quad model and i would try to print it with my prusa.
