This is simply because Fred is selling the wrong software for this problem. Yes, he is completly correct that using a CAD/CAM system to do simple operations is slow. Thats my point entirely with CPNC-

Had I been at Names and heard the crowd shout down Fred over the use of manual machining , I would have jumped up and told the hecklers to sit down and shut up. Fred is right!. There are countless

This (cnc vs hand cranking) is one of those subjects where we may as well agree to disagree and let it go. I only use cranks, but only because i didn't get trained on the CNC machine yet. I see the

I think the point Fred is trying to make is that CNC is not always the best choice. Considering the business he is in (selling CAD/CAM software) I think it is pretty honorable that he would point out

Darrell, On my EMC install I can get up to 80 ipm or so and that is WAY beyond the instantaneous move capability of my steppers. I am running the freqmod setup on an AMD K6 500. If you are running

I'm a little late getting into this thread 'cause my eudora's not real happy with cad_cam... I saw Ron's software at NAMES and was really impressed. I know of production machine shops that do

Jon, What you say may be true for servo but not for steppers. To make steppers work properly we need something past the Linux box to create smooth step pulses. The problem with EMC and steppers now is

Jim, AutoCAD LT is a first rate 2 D drafting program (limited 3D). I started using AutoCAD (the real stuff) at version 2.17 (long time ago) ...... and more recently (because of job changes) ended up

I think it depends on the part and if it for an assy or not (degree of accuracy needed). I do drafting/designing and 3D solid modeling for living (Pro/E) and I still sketch out parts on paper once in

The only way I know of to get around the tendency of Windows 95+ and NT to go to sleep is to use some form of intelligence in the controller. "Real time" NT apparently isn't. There are PC cards made

For those of you who missed the little CNC discussion forum and presentations, I was not pushing Vector at all (it was in the title, but not the words). I merely showed when it is best to use CNC as

Ron, Take a look at www.simplestep.com for their serial interface intelligent controllers. They come in single, dual and three axis versions and use serial interface to the host PC I thinks you

I think that drawing by hand is great for quick sketches, and in my case sending our preliminary drawings for price quotes, but there's just no comparison to using CAD. This is especially true when

My wife, who was dragged kicking and screaming from paper to CAD (space planning / architect) still maintains that paper is faster for preliminary drawings, sketches etc. while one works out a design,
