Just for a little humor here I can't tell you the number of times my workshop's electric garage door opener get's triggered when bringing Mach3 online! Seriously!

I know there must be a stray signal coming somewhere from my control box that happens right when Mach3 gets through loading. Happened some many times I've come to ignore it and just walk over and hit the button to close the door.

Just remember... it can always be worse!  ;D

Dickeybird,
I dare say even though you've managed to get the jumper between the vaporized track, you've more than likely cremated some IC chips. They're relatively inexpensive from Arturo.
I had to replace mine before I could get any control on the speed changes.

Simple investment of time to replace the chips. I did purchase an IC chip extractor from Radio Shack because the first one I pulled flew out of my feeble fingers across the workbench. When I picked it up there were bent legs everywhere. This happenend in the blink of an eye.... pull, pull, nothing... pull some more... umph!...launched the chip into outer space... <Grin>

Would you be willing to share this?

Thanks in advance,

Pin 12 is working with a Proxy Switch. Just can't get it to work with the optical one.

Okay, I've managed to bet a pulse from the setup shown in the attachment.. well sorta....

Looking at the dotted burgundy colored line at the top: when I have an 5v LED and a 1K Ohm resistor inline I can visually confirm that the LED pulses when a reflective portion of something passes by. However the LED on the c11 board does not. So I thought maybe the LED and Resistor are pulling too much current and removed it. (as shown in the orange line). Still no LED lighting up on the c11 board.

I tried using low and high settings in Mach3 but didn't get anywhere there. (both with the extra items inline and without).

Should I put a pull-up or pull-down resistor between the Pin 12 and its neighboring 5V terminal?

Got feedback from Arturo. I'm on my own on this one.

:o

I have verified that a proximity switch will in fact invoke the LED for Pin 12 to come on when a magnet passes by its end.
Pin 13 LED or circuitry may now be cremated from my various permutations of wiring.  

Man I hate flailing around like a fish on the sidewalk...


Anyone care to tackle it?

I had a macropump that would compare the commanded speed with the true speed and if not within 10% it would E-Stop...
Hood

Now that would be a useful tidbit to have.

I don't have a ModBus so would you mind sharing it if you still have it squirreled away somewhere?

Wondering if someone could take a look at another Opto Sensor type. It's the HOA1405-001.  It doesn't require a slot because the IR LED and the Sensor are pointed at an angle to each other so all that's needed is a reflective spot.

I'm just to ignorant to make a definitive call on how the wires go together.

I'm using the cnc4pc c11 board.

My thoughts were as follows but it didn't work.
C - Input Pin on BOB
E & K - Wired together and put on GND of BOB
A - Place 220 Ohm resister prior to connecting to 5V on BOB.



Any advice would be appreciated before I destroy something. I don't want to fry the IR LED nor burn out the Sensor. Also want to make sure I put the Ground wire where it's supposed to go on the c11 as well.

I have been trying to get the c11 board to recognize a signal from both the opto-sensor as well as a magnetic sensor for spindle speed.

I have tried multiple wiring configurations, but only if I thought they were safe and no danger of messing up the c11 board.

I have set Mach in various permutations of debounce numbers, active low, enabled, etc. for both the Input settings and the Spindle setup tab.

I've tried with and without a 4.7K Ohm resistor across the 5V and the Pin 13 wire (just like my probing setup) but can't even get the LED to light up on either Pin 12 or Pin 13 no matter what I do.


Any help would be appreciated.

I just opened a Work Ticket with cnc4PC a few minutes ago so understandably I haven't heard anything back yet.

Thanks,
Vogavt

Talked to Arturo and got some other things sorted out, but we didn't get to work on the above post's question about wiring the opto.

Anyone got any comments?

Finished Screens / Button Reference Sheet

Hmmm... Okay, I'd have thought you could make the DRO show whatever you want it to via a macro. (Don't know enough to talk any more about it.)

Here's a reference sheet I made for the buttons. Others may find it useful until they get used to their setup.
