Re: CPNC and Patents
Ron Ginger
I have read the notes about patent issues and am now concerned. I know
there are a few cases of crazy patents being taken seriously- like Amazon.com patenting the use of cookies. I know this group is not a source of real legal advice, but are we at any risk if we start a public project to do a conversational program? Is there any company doing a conversational program and not paying royalties? ron |

I am actually building the PCB mill a lot like you suggested. The mini was for machining small parts. In fact you are the one who got me started. I'm on the PIC list as well. I am waiting for the motors and linear bearings to come in. Thanks Larry Jim ----- Original Message -----

I also do a lot of PC board routing. But I wouldn't use a mini mill for that. Not enough work area. A better option for PC boards would be a simple 3 axis router made with MDF, bronze bushings, shafting and lead screws. You could even make it with drawer slides. If you do use a mill, you'll need either a sheet of MDF or a sheet of aluminum to use for the PC board work surface. Double sided tape works but the best option is a vacuum hold down table made from two sheets of MDF. Hook up a shop vac and the blank will be held down firmly and flat.

Some pictures of a retrofit
Rich
Group,
I was talking to a manufacture of a CNC controller and they invited me to come to their shop and look at a HF mill that had been retrofit. This weekend I was trying to figure out how the free web storage space, from my provider, worked . Here are some pictures I took with my Sony Camera: . Their setup looks fairly simple. So much so I think will try to retrofit rather than buy one of the small CNC mills. Perhaps, someone else on the list will find the pictures helpful. Rich |

I copied the following from alt.machines.cnc:
"The website links to vendor web-sites offering free 2D/3D CAD, CAD/CAM, FEA, Thermal Analysis S/W and other mechanical utility programs for downloading. The site does not distribute any software, but describes the applications (with screen-shots) and where they can be downloaded from.

Re: DIY CMM ??
I am also building a DRO setup(for my & X 10 mini lathe). I am
wondering if anyone has programed Tom's DRO in visual basic. I am not even sure if it is possable in VB. I would like to make a GUI spcific to my lathe. Settings for the toolpost angle, postion for the saddle and crosslides. The ability to enter the as cut size, desired size....etc. Any help out there? Thanks Jeff I'm also in the planning stages of building a 4-axis DRO onmy 3-in-1 using the board kit from Camtronics, so if I could some howuse the same computer andmuch ?

Assuming equal proficiency with a drawing board and a CAD system, isWhen trying to solve a fairly complex mechanical problem, the old fashioned "scribbling on a napkin" is still about the best way to quickly visusalize general concepts.

The direct link between brain/pencil/paper offers speed for conceptual visualization that will not be equaled by CAD until neural implants become viable. Jon |

This one is done. The code is there. I haven't been able to get the whole thing set up on one of my machines, but have hooked up the encoders from my servo lite system to the card and run the EMC software with the motor power off. It does seem to work. Now, I need to figure out how to keep the Servo Lite electronics and the DRO card from interfering with each other. What I want in the end is a DRO screen along with a CNC. CNC Pro break out board.Several members of this list have offered to do this. Ray is loading up a box for me now. Matt will do it and Dan Mauch. They are out there if you really want them. lower cost STG replacement card.Thanks, Dan |

Message: 11[You are running in straight DOS, not under a Windows dos prompt? While Windows appears to run DOS, it doesn't give you control over the parallel ports.] [It sounds like one or more of the Darlington transistors in the control box may have fried, possibly when the parallel port melted down. These PIC-120's are available at Radio Shack. I find it helps to get Otto on the phone when you're standing next to the machine, then have him talk you through the diagnostic; holding the phone up to the motors, if necessary. One thing to try- switch the parallel port cables from the z-a card to the x-y card; this should tell you whether you've got a parallel port problem or a bad control card.] [I hope this helped, but if not- talk to Otto- he's the only one who really understands these things.] Andrew Werby - United Artworks Sculpture, Jewelry, and Other Art Stuff |
