General Mach Discussion / Re: Help Set Me Straight ( Limit and Home switches)

Well I found part of my issue, and that's because I've gotten a case of dyslexia. I wired them into the wrong terminal spaces and then set the pinouts in reverse order. Now I think I may rewire them with a shielded wire just to be safe. I've got a couple of days off from work so I'll be attending to that soon. I'll let you know the results of my efforts. Thank you much, Brian.

Yes that clears it up for me. I presently have it set to 900 in both field boxes. I think I'll upscale the number to 2000 so as to have no more dealing with that! Now back to my switch problems. The X axis is still not responding, so I think I'll rewire and see if thats the problem. But until then do you have any input on the subject, Brian. And thanks for the help so far. I'm in good hand I think, yes?

basically you are telling the computer to ignore any input that is on for less time than the debounce. So if you have an input that is on for 100 and have the debounce set to 200 I will never read the input! You can crank it up to 2000 no problem! That is only like 4 Milli sec.... You will never even know it So as you can see it is to filter out noise that could be coming in to the input....

How is that?

OK checked those things, and yes, if I press the button, in my case the Y axis, they both light up. Home is set to NEG. What should debounce be set at. And what the heck is DEBOUNCE anyway. Looked up in Wiki and I don't understand the definition. Please explain in plain English??

Hello!
You are going to have to check that you have the machine set to HOME NEG. Also what happens if you press the X axis limit switch? It should show both the X home and X - limit switch actice on the Diagnostics page. If that is all okay we start to dig

I will check those things and report back the results. Thanks Brian.

OK Benny, I'm game. What are the design constraints, parameters. I guess that none exist or I think by now that you would know where to get it. When do we start?

General Mach Discussion / Help Set Me Straight ( Limit and Home switches)

« on: February 01, 2006, 05:23:08 PM »

I finally got around to mounting my limit/home switches,here's what I did. I used SPST momentary push button normally on type two conductor switches. I connected them to a cnc4pc breakout board as directed by schematic. Using solid wire to connect them together and shielded wire to connect to breakout terminals via a RCA type plug between board and switch. As for settings I used  X++ port 1, pin 10, X-- port 1 pin 11.  For  X Home port 1, pin 11.  For Y++ port 1 pin 12, for Y-- port 1, pin 13, and for Y Home port 1, pin 13. Axis X, Y Homes are shared. I then unchecked the boxes to set them on active high. Now how do I set the soft limits? Is one set to zero and the other set at the length of travel, such as -0 as soft minimum and +12.00 as soft maximum? Can someone with a working machine look over my scenario and recommend the proper changes or tell me what I am doing wrong!. I get the Y axis to work, but the X axis will not, and if I touch the wire that connects the Y switches it triggers the limit on. Also what is a good setting for debounce, whatever that is? Man, I hope someone can help. I'm buggin' on this.

General Mach Discussion / Hand Wheel and more

« on: January 31, 2006, 09:27:09 PM »

Is it OK to move an axis with a hand wheel? I mean when I will set a zero at a material heights, so as not to hit the surface to hard with jogging only? Also, I'm setting up my home/limit switches and I've got the Y axis working, but the X doesn't register. And, while it's in the X mode, if I should put my arm across the table it triggers the Y LED. Any thoughts on that situation. Should I be using shielded wire instead of solid ribbon wire? Are the limits set up one by one with a restart between each settings?

General Mach Discussion / Where to put it?

Is there any optimal position for a router body on a Z carriage? I mean does the Z travel, mine is 3.00", have a determining factor to where it is mounted on the Z axis? Sort of top dead to bottom dead travel?

Anybody here have a source for a decal for Mach 3 ?. I'd like to add one to the front of my control box, to let people who's in charge. And while we're on the subject, how about Gecko decals?

Could a spst momentary push button switch the type commonly available at Radio Shack be used as a limit/homing switch?
