General Mach Discussion / Need limit switch help
« on: July 17, 2006, 07:20:27 PM »
Have my X axis up and running but have no way to keep it from crashing into the frame if I make a mistake on my Gcode. Running 640 motors and Geckos with Mach3. 1. Do I need to order NO or NC? 2. Where to get them? 3. What wire to interrupt? 4. Do I need to change my Mach settings? Any help will be appreciated.

Ooops Brian I think you mean a Macropump ;-)

The charge pump thing is a circuit Mariss at Geckodrive designed to allow an extra safety feature in cnc programs.

The circuit is a one shot circuit that turns on a relay if and ONLY if a 12.5Khz signal is seen on the input. Mach puts out this signal if you can use it.

If the software or the pc crashes then the relay is de-energised, which can cut power to your drives etc.

Also avoids any clunking and motors turning on at bootup.

If you want to play safe then yes you need it.

Wayne...

"signal is seen on the input"   It will help me a lot when I get the jargon figured out. When you say "input" are you talking about data that I send from my keyboard to Mach?

I just now realized that I had failed to carefully read this post. Thanks Wayne. That's an explanation I think I can work with. I don't know precisely what it means but I think I have a good enough idea of how to check into it. I'm only now to the point (in my build) where I am able to power up my system and watch my three motors run while clamped to a table. I haven't built my chassis yet. I've noticed that when I power up I always hear a clunk. Just one little clunk. I have no idea what it is but I think maybe this is what you're referring to. I hope you're not saying this is harmful.

General Mach Discussion / Mach Tutorial
« on: April 27, 2006, 09:49:19 AM »
I'm satisfied I'm the only one who needs it because I don't see a single other request for it. But I would love to have a tutorial on how to use the program. I have Mach3 downloaded. Beautiful to look at. And I have my newly built CNC appratus standing by for test run. But I simply do not know where to begin. I saw one poster make mention of video tutorials. But I don't see them anywhere on the site. Can anyone help?

I apologize Mr. Barker. My learning disability causes me to get frustrated much faster than the average bear and that causes me to get angry. I'm very sorry.

If you can't find them I will post the links for you

No. That's fine. I like a challenge. I'll give you a shout if I can't find them. I'm off today so I can look and look. On the other hand, I think I just got a sample of your support services. Price is important but I would surely have a problem sooner or later and then I'd be pissed at myself for going cheap at the cost of getting no help. Adios.

If you look there are a few other threads that tell you what you should have for a computer...
I did. But I'll try again. If I can't find it I'll see what other options are out there.
