Your Best Investment is in Yourself.

Everyday I am bombarded with advice from advertisers.  They want to tell me how, when and where to invest.  My experience has been that the banks pay a small percentage in interest but take it back with service fees.  the stock market is a roller coaster that may produce 10% on an investment over a long period of good times.  Gold has never been worth zero, I am told, and may increase in value as much as 20% next year, if times get worse.  Everyone else seems to be giving advice so I'll take a shot at it too.

How do I mill a 6 foot sign on a 4 foot Artisan bed?

Milling a 5 foot wide sign on a 36 inch Arty CNC

One of the three areas a CNC operator needs to master is the setup.  How do I mount the stock?  How should I break up the code, if necessary?  Should I break the job up small sections?

This sample project is the result of questions raised by Wayne Mack of London, England.  Wayne is an old friend and owns one of the first Artisan’s produced.  His questions was simply, “How do I make a 6 foot wide sign in my 4 foot Artisan?”

This is how I set up a similar job.  I hope you find this helpful. Andy

Step 1.  Build a work table with fence.


After referencing the machine I used the MDI window to enter the following command.  G90Y.25F100.

Legacy's business philosophy allows you to invest with confidence.

Over the past twenty years Legacy has evolved from a simple idea of how to harness the power of a router to a company that designs and manufactures the coolest woodworking CNC machinery on the planet.   Our business model has always been very simple; we reinvest the company's profits in research and development and state-of-the-art machinery for manufacturing.  By manufacturing locally we are able to improve on an idea or take an entirely new product to market very quickly.  In just the past year we have introduced 3 new models with over 20 configuration options.  This constant focus on R&D means that the machines that we build today are better than the machines we built yesterday and the machines we build tomorrow will be better than  what we build today.  It may not happen quite that fast but you get the idea.

The problem with such rapid development is that many potential customers hesitate and don't dare buy because their CNC may soon be outdated.  Legacy allows you to invest in a CNC with confidence knowing that you won't be left behind.

The New OM5 Interface Sneak Preview

Legacy has made great progress on the new OM5 Interface.  The controls are more intuitive and easy to understand and you will be able to setup and run everything from one easy to use screen.   If you need a little more control we have the advanced screens available at any time.

The main screen is broken into six sections; program control, DROs, tool path display, setup controls, jog controls and feed / RPM controls. You'll start with

Fix for Artisan Constant Velocity

Working with the main software engineer at Artsoft (Mach3), Legacy has determined the fix for the jerky motion several owners of the Artisan CNC are experiencing when carving.  All Artisan CNCs shipped after 1/28/10 have the proper settings.  We’ll start by explaining the two path control methods available for Legacy’s complete line of CNCs: Exact Stop mode (G61), and Constant Velocity mode (G64).  “In exact stop mode, the machine stops briefly at the end of each programmed move.  In constant velocity mode, sharp corners of the path may be rounded slightly so that the feed rate may be kept up.  These modes are to allow the user to control the compromise involved in turning corners because a real machine has a finite acceleration due to the inertia of its mechanism.  Exact stop does what it says. The machine will come to rest at each change of direction and the tool will therefore precisely follow the commanded path.  Constant velocity will overlap acceleration in the new direction with deceleration in the current one in order to keep the commanded feedrate.  This implies a rounding of any corner but faster and smoother cutting.”  This is particularly important when carving.
