FAQs / Re: Port 1 Pins not lighting

« on: July 27, 2010, 03:37:58 PM »

HI,

Well guess what. They now work and I don't know specifically why . . . Don't you hate that.

Anyway, I didn't have my limit switches reconnected from my last crash so thought I'd see if I could get their lights triggered when hit with no luck.
Then I tried the automated set up for limit switches and that didn't work either.

However, it was at this point that my Port 1 pins started working again. Hmmmm???

Anyway, success is success. I'll take it any way I can.

Thanks for feedback and the parmon download. Keep on Cuttin'

FAQs / Port 1 Pins not lighting

Please help if you can.

Had to replace computer from a crash and ever since my port 1 pins ( on the diagnostics screen) aren't lighting although my CNC machine works great.
Any thoughts

Trying to purchase shielded cable in a small town is frustrating since no one seems to know what it is.

We do have a Home Depot and they have something called CAT 5 Twisted pair cable but it doesn't specifically say it is shielded.
Will this work or could I use Coax Cable for this job. Do I ground the shield portion and if so where?

I am definitely getting interference from the 5v source. Too bad I can't use the common or ground sources on the board.

One final thing for the record, I wasn't using shielded cable to connect the Limit Switches in series.

Thanks again

Hood, You are a genious!

I set debounce to 2000 and guess what, when I "Ref All Home"  the "Z" went to "Home" and then backed off a bit and then continued on to the other Axes as expected and did the same.

Very confusing when following the setup videos that are trying to be Generic but don't work for all BOB's.

Many thanks for your help. You managed to get one more CNC'er up and running. Keep up the good work.

Now I can concentrate on doing something worthwhile!

Hope I can somehow contribute to the Forum in the future.

Hi Hood, This is what I sent to Arturo and his reply.

Subject: Enquiry from CNC4PC

 

Hi,

I am trying to set up my limit and home switches using your CNC4PC C10 board and having problems.

Board jumpers are as they were from the factory, ie. pins 2-9 set as output and 2-9 common set to Ground.

When I hook switch up to Pin 10 (or 11 or 12) and the other wire to any of the 2-9 commons and set the port and pins in Mach3 to "enable" the program doesn't react in any way. ie No lights in the diagnostic screen.

However, if I hook up the switch up to pin 10 and then to any og the 5v sources, the switch is recognized but it physically doesn't stop the motor.

Tried all of the forums but no luck. Am I missing something.

Al

He replies as follows:

Al,

 

Sorry for the delay in getting to you.  I was taking a couple of days off.

 

You have to go to: Config / Ports&Pins / Input Pins.  There you have to assign the pins.

 

Have you done this before?

 

Is everything else working ok?

 

Thanks,

 

Arturo Duncan

As you can see, he missed the text where I said I "enabled" the ports and Pins and said nothing really. So I wrote back the following:


Hi,
 
I think I have it figured it out now. When I connect to pin # 10 and to 5v not ground and put a check in the active low box everything works. ie. when the switch is closed, the motor stops.
 
Originally, I was led to believe pin # 10 was supposed to be connected to ground!
 
Thanks
 
Al

He replied as follows:

Al,

 

I am glad all is fine now.

 

Thanks for letting me know.



OK, so I said I got it working in some manner but it's still not right according to the Mach3 set up video and I still don't know what's wrong.
I can get the machine to "Ref All Home" under this 5v scenerio, but it won't back off the "Z" switch unless I disable it and jog off then when I "Ref All Home" again, it homes the "Y"
but won't back off etc. as above.

At this point I'm ready to give up on limit and home switches but I realize this is foolish and would like to figure it out once and for all.

The funny thing is that I have the router working beautifully with mach3 and lazycam.

Can you come up with anything that might get me out of this delima?

BTW, Thanks for all your efforts thus far. I do appreciate it and realize this is a volunteered service with little reward other
than the satisfaction gained when you actually get a fellow CNC'er up and running.

Let's give it one last try.

Hi Hood,

Sorry, I missed this post until today. No, I haven't contacted Arturo but will send of a note to see what he has to say.

Tks

My BOB is a CNC4PC board model C10.
You can set pins 2 thru 9 as input or output, mine is set to output and you can set the 2 thru 9 common pins as ground or 5vdc, mine is set to ground.
The tutorial video instructs one to connect the switch to #10 and to common. (I tried this with 10 & 11 with same results ie no recognition whatsoever). BTY the connections to the switch are to the NC post and the C post.
