Hi ya’ll, is nice Mr. mc still on board??  I’m trying to make sure I don’t do something really stoopid with this pull-up/pull-down thing.  My latest grandson isn’t quite ready for pull-ups yet so I better get busy.  The other 3 figured it out for themselves so I reckon they’ll all be electronics whizzes.

I now have the hardware mounted solidly with a NO micro-switch adjusted to close about 3 turns of the stepper motor before the axis bottoms out and I mounted the opto on the motor with a half-circle disc on the motor shaft.  The opto is powered up with 5V and gnd from the C11 B.O.B.  The micro-switch is connected in series with the SIG wire from the opto and I stand ready to connect it to the B.O.B., pin #12.

I verified that the opto operates as shown in the spec sheet ie: sensor blocked .16v, sensor open 4.9v which is backward from the example given above by mc.

What’s the preferred method of hookup re: sensor/disc block/unblock, pull up/pull down.  I know, I know it’s real simple but my almost 65 yr. old brain confuses itself very easily.

You guys need to hook up with a reality show producer and get this drama on TV.  It'd be a lot better'n friggin' Gold Rush or American Chopper.

  With all the problems you solve on the forum and all the "real" work you get done I visualized a fat lump on the couch in the corner of your shop with a pile of meat pie boxes and Belhaven bottles stacked up beside it!:)

You`re lucky you`re only visualising it,I`ve seen it.

No fair editing my post & takin' the pi$$ while he's asleep on the couch.

How'n'ell you wrote all of that without a nip or two I'll never know.  One thing's for sure; I'll have to dry out for a couple weeks before attempting anything close to that!

Seriously though, you do have a gift for explaining things to us dumba$$es and it's much appreciated.

...tonight when I get home.

You go home at night?  With all the problems you solve on the forum and all the "real" work you get done I visualized a lumpy couch in the corner of your shop with a pile of meat pie boxes and Belhaven bottles stacked up beside it!:)

Cool, thanks Brett.  I saw that the PLC comes with software to set it up so using that you tell it what input signals to look for and what you want the outputs to do?  Sounds like a little standalone computer that can do many and wonderful things as long as you configure it properly.  Nifty, that.

Hopefully Hood will touch on what the toolchanger looks for to do its job and how he sets it up later on when he gets around to it.  (Not that I have a toolchanger on my ORAC....yet. )

I guess the best way to reduce my ignance is to ask ignant questions.

I found your DirectLogic PLC's website and looked around a bit but am still clueless other than the fact that if I ever get smart enough to need one, that's the place to go to save my money!

I don't have any experience at all in industrial automation so am curious about what it does and how you control it with Mach.  Got a dumbed-down explanation of what it does and how you make it do it?

Thanks!

Looks like whatever was clipped on the DIN rail on the left side in the 2nd pic was runnin' a bit warmish, eh?

Luv to watch your re-do's!

Thanks mc!  You explain things so clearly even I should be able to get it working without letting any smoke out!
