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.
Al
