"One Perfect Part at a Time"

MACH3

Gearotic Motion Software

Sounds almost perverse but that’s the name of Art Fenerty’s latest software. If you don’t know, Art is the creator of the MACH3 series of affordable CNC control software. Art has sold off MACH3 about four years ago so has had time to design gear making software. MACH3 is still very popular and widely used.

I love gear action and when I saw this in a mailing from Bob Warfield (CNC Cookbook) I knew I had to check it out. Here are some links to Bob’s blog and an explanation of the software directly from Art Fenerty:… Continue reading

Hardware Pulse Board for CNC

I am going to make (hopefully) an improvement to my CNC operations in a week or so. I have ordered and will install a USB SmoothStepper board made by Warp9 Tech Design. Inc. into one and maybe both of my homebuilt CNC controllers. Probably the first one will be installed and tested in my original chopper controller that I am now using on the Taig CNC mill.

I have used a serial pulse generator before in that controller. Years ago I obtained the pulse card from DeskCNC called their 2nd Generation Controller Board. It is actually still installed… Continue reading

Milling Wax Adventure

The year is running out fast. I will soon have to say good-bye to 2011. This is the year (last Saturday actually) that I became 65 years old. Time enough for pondering that event, now to keep moving. Ha!

I did some machining of wax on the Taig CNC mill Saturday. I love machining wax (the hard blue kind). The wax is not good for creating real finished useful items but it makes excellent models for making molds and doing casting.

I spent the morning doing the design work in VECTRIC Aspire software. I was creating a Christmas… Continue reading

Thoughts on CAD/CAM/CNC

I am going to take a time out here from the product specific (BobCAD-CAM) examination I am making of a CAD/CAM software product.

I consider myself a competent self taught hobbyist CNC machinist. I didn’t get here without a lot of study and hands on practical experience. Let me say I have paid for my mistakes as well as my successes. The creative process of following through from an idea, to a sketch, Computer Aided Design (2D & 3D drafting), Computer Aided Manufacturing, (generation of Computer Numeric Control code), Controller (MACH3) set up and finally understanding the physical limitations of… Continue reading

CNC Gun Part

A local person here in Frisco asked if I could duplicate this part (the black one). I don’t usually like to take on outside projects as I have enough of my own. This part looked interesting. It is part of a tripod bracket for an expensive, but what the owner called a “toy” gun. Actually is is a very sophisticated collector item.

As can be seen in the photo the bracket had the tab broken off. It is a very nice injection molded aluminum casting but the crystallization left it vulnerable to breaking where it did.

I… Continue reading
