Now, the software used is MODELA Player4 from Roland. Open the .stl file. As the numbers above show, FIRSTthe machine has to be selected. For that, click on FILE, Machine Selection, and choose MDX-20 in Model Nameand Printer Name, and OK.Then, for machining we will need two things: roughing and finishing. Roughing will take out all the material andit usually leaves a 0.1mm offset surface that feels like zig-zag or stairs, whereas finishing will directly go to theshape to take off those 0.1mm of excess and thanks to it, the surface will look and feel smoother.To begin with, we choose New Process and Roughing.

When selecting the process, the windows above will appear (I am ignoring the real first one, and the real second oneappears here as 1).In 1 (Cutting Area), you have to select what surface to machine. It could be All, but if it’s Partial you will control the redframe and move it with the arrow. In 2 (Tool), you choose the bit (I used 3mm square). In 3 (Path Type), I chosecontour lines down cut. In 4 (Cutting Parameters), you will have values given by the program. The ones I could changewere Cutting-in Amount to 1.4, and Path Interval to 1.7 (which should have been 1.5 or less). The noise might makeyou go crazy, but it will take less time to be ready.

These blue lines show the way/direction the bit will take. For a value of Z (high), it will machine all the selected surface,then it will go down 1.4mm and machine all the surface, and so on. At the end, it will leave an offset of the surface (0.1mm aprox. as specified in Finish Margin).Once it is ready, click on CUT to send the file. This roughing process took around two hours to be accomplished.
