Introduction

Basics

: put a picture of the machine with caption

The “Circuit Imprimé Francais Technodrill 2” (CIF) is a 2.5 axis milling machine. It is capable of milling/cutting parts with:

File Formats: .DXF , .DWG , .NC , .TXT , .ISO , .PLT
Max Dimension : 30cm X 29 cm X 1cm (X Y Z)
Materials: MDF, Styrofoam (there exist multiple densities), High density Wax, ABS, Carbon Fiber, Wood, Aluminum

The CIF is equally capable of engraving “Printed Circuit Boards” (PCBs). To create PCBS we we use:

File Formats: .GBR , .NC , .DXF

However, we primarily use the .GBR (Gerber) format as it is a standarized format for the fabrication of the CIF and allows for the most amount of control of the fabrication process.

The CIF is controlled through an interface called “Galaad” which allows for basic design work and the generation of “Gcode” (A standard language used to communicate with the motors of a CNC machine). However, we do not generally use Galaad for it's design capabilities as it is far inferior to dedicated design software (see below). We use Galaad primarily as a “Computer Automated Machining” (CAM) software or a bridge between the design software and the CIF.

Softwares

For parts destined to be milled:

Autodesk Fusion 360
Autodesk Inventor
AutoCad
TinkerCad

These softwares are professional grade within the professional world and is offered free for all students ici.

For the conceptualization of PCBs

KiCad
Eagle

These two softwares do the exact same work and have the same functions. The preference for one over the other is largely subjective and is generally based upon which program you learned first.

In the case of a cable becoming accidently unplugged we have provided a basic schematic of the wiring. All of the cables are marked appropriately on the CIF respecting this diagram. In addition to these wires there is a USB flash-drive that must stay permentaly plugged into the computer operating the CIF. The license is on this USB drive. DO NOT TOUCH THE USB!
