The schematic showed up for me. But there's something I thought, that the 7404 could hand multiple switches... not just one. I believe up to 4. But I would...
I'm beginning to wonder if the speed issue is caused by the computer I'm using. As I understand it, the circular interpolation routines could eat a lot of CPU...
The document is in MS WORD format but folks with older versions may have trouble with the graphics. I'll try to convert the schematics to something more...
Larry, Art: Arc motion (G02/03) uses another parameter to limit the feed . It's based on your computer's speed, named 'ArcFactor', and is adjustable under the...
... Mine's a P200 - A Toshiba CDS-315 notebook computer. I don't think that the computer speed difference would be significant. The circular interpolation may...
Hi Larry, I got into this thread little late, so I may have already missed your answers. I'm confused about the "Adjustable Supply for Optical Diode". A...
There are two makes in N.A. - Unittool and Unipunch, very similar in a design. I got my hands on used Unipunches, they look like from prewar times, but the...
This is good to know. I checked and mine is still set to the default (1). I guess I can set it to 0.5 and see what happens. Larry ... It's ... adjustable ......
Jerry, I'll send you my file. I'm using TurboCNC V4 Hot_fix downloaded last week. I assume that's the one you're referring to? Larry ... computer ... ...
Hi, No problem, you didn't miss much. Adjustable supply - This is needed to provide a solid voltage for the optical switch. These switches are VERY picky...
Hi Larry, Thanks for your comments. I'd never heard that optical switches needed that close a tolerance on their LED emitter voltages. As for caps, I always...
Alan, Yes, it seems unreasonably tight, but that's the spec (absolute max is 1.7V, but they degrade at 1.7), and its consistent with what I've observed -- I...
Hi all, Well I had a need so I created another vbs style program to help speed things along. The problem as I seen it was that the output from Ace Converter...
Hi, can anyone tell me if it is possible to download high res original images from the file area? eg in this case it gives file size 331kb but I can only get...
Why not use the QVE00112 from Fairchid... Only need +5v and GND... and one signal that is ttl-comapible. No need for "homemeade" powersupplys and all the...
Sounds good -- can you recommend a source that will sell in small quantities? Jameco doesn't have it, nor does DigiKey (last fall catalog). Larry ... and one ...
Hi Larry, It sounds like your optical switch uses an LED. LEDs should never be driven from a constant voltage supply. An LED has a forward voltage of about...
Hi, Craig: Unfortunately, you can only get the "condensed" versions. As I understand it, only the list owner (and possibly the moderators) and the person who ...

Hello Carol & Jerry; I figured out that run from disk was listed in the program as "run from file". I found a way around the editor memory limitation by...
Les, If you say so. I can tell you I've tried as you suggested and the parts fail very quickly (a couple of hrs). Much of the spec I have is in Chinese so I...
turbo developers: I've been wondering--does tcnc cross-check itself internally by counting accumulated pulses? In other words, it seems like there are two ways...
hello all! I've one question about tool change. Machine have one head with two tools inside. For the first tool it uses master coordinate (t0 or G53 default)....
Rob: This is a great quaestion. We use both the actual step count and the requested destination to keep track of position. This is required because a spatial...
