Ace Converter software program is free and will take two dimensional DXF files and convert them to G-code. Ace converter is an application that translates CAD (Computer Aided Design) files into tool path files. The resulting G-code program can then be loaded into a CNC to start machining with some minor tweaks.

CONVERT software is FREE!! One of the greatest free unit conversion programs tools available on the internet. This Copnvert software is provided by Josh Madison- thank you Josh for such a great free utility.

This conversion software can do all the common units of measurement and convert them to other units such as miles into feet, or convert mm to inches, pounds to pints and more.

• Conversion of
• Pressure
• Speed
• Temperature
• Time
• Torque
• Volume
• Volume-Dry
• Acceleration

• Convert calculations and calulator between inch and metric
• Angle values can switch between Degrees.decimal and Degrees,minutes,seconds
• Right angle and oblique trigonometry
• Speeds and feeds, RPM to surface speed, etc.
• Drill point and countersink depth calculator is with the drill charts
• Material List application for help in calculating speeds and feeds.
• Drill size conversion charts, tapping drill carts
• Ballnose cutter/surface finish calculations
• Chord data calculations

SolidCAM is one of the leading and fastest-growing CAM system running in SolidWorks which is a 3D CAD software commonly used today in manufacturing for 3D design engineers.

This software has all the capabilities you would expect from a CAM software package such as 5-Axis machining applications.

Features of SolidCAM software include:

• 2.5D Milling
• 3D Milling
• High Speed Machining (HSM)
• Multi Sided Indexial Milling
• Simultaneous 5-axis machining
• Turning
• Mill-Turn up to 5-axes

Mach3 is very popular among the Hobby CNC community.

Artsoft produces Mach3 software and has been around for some time. This software can be used as a fully functional CNC control or used as a CNC simulator for training, learning or testing CNC programs. This is also a great CNC control simulation software that you can install on your own PC computer. There are a couple tweaks to the configuration that you have to do before you can test it like modify the pinout configuration to bypass the emergency alarm that occurs on install, but that is about it.

SDNC RS232 communications software by Surfcam use to be offered for free on there website. Unfortunitly that is not the case anymore. This was one of my favorite free RS232 Programs that I still use today as I still have a copy. However its only available to you if you own a seat of Surfcam. I think this was a great way to promote there software, so if you would like to make the request to them for the free version again it might be worth a try.

This software can have multiople machines all set up with different settings. The layout and self explanitory menus are great for anyone to use.

NClink RS232 communication software is Provided free from OneCNC all you need to do is register.

Its Fully functional with no limits. NClink also has an NC editor built within the RS232 Program. If you are looking to dripfeed your programs to your CNC machine NClink RS232 is fully capable of it.

You must wait a little for the advertising portion of the software to go through before entering program but Free is Free.

Tera Term Pro is a free RS232 software terminal emulator

(communication program) for MS-Windows. It supports VT100 emulation, telnet connection, serial port connection, ethernet and so on. They also offer Tera Term ver. 1.4 for Windows 3.1 for anyone using or needing a RS232 Communications program for older versions of Windows. It appears its only supported for win95 win98 and NT though it seems to function on XP when we tested it. There is no support since its free so use at your own risk.
