Re: [Emc-users] Triggering an external relay from a BOB

[Chris Albertson]

Sorry about the last reply written before seeing the posted manual.
As Gene points out it is "14" or "4". But also, my guess is you
need to supply 5 volts to the board via either a power supply or a USB
cable.

One why to debug this is to but a voltmeter on the relay coil and
toggle pin 14.  If one end of the coil is at ground, look at the other
end.

Re: [Emc-users] Triggering an external relay from a BOB

[Chris Albertson]

My first guess is that the BoB can't source or sink enough current to
energize the relay coil.   But we have to know what exact relay, power
supply, and BoB you have and exactly how they are all connected.
Could you post a schematic?

Acc those drawings, the relay is controlled by pin 14's logic output.
So your use of pin 4 is not getting anywhere near the relays coil.  That 
is the first thing you need to change/fix.  The next question then 
becomes, what sort of a spindle controller are you using? To "do it 
right" often demands a controller made to be remote controlled, and TBT 
if considering the re-use of the controller that came with a treadmill 
motor, its lack of finesse at being controlled is going to expose you to 
both dangerous voltages and a difficulty in adequately controlling it 
thats just not worth it.  So what is the motor you wish to control? And 
what controller will you be using?

There are available ways to do it that are designed to be controlled.  
But because there are also as many motor styles there are also 
controllers made for each style of motor.  But they can't be mixed and 
miss-matched.

[...]

Stay well and safe, Dan.

Draw us a back of the envelope schematic. scan & post it. As a retired 
CET I can read that easier than this text. But bear in mind the logic 
output available is going to be quite a ways from enough current to 
reliably operate most 5 volt relays as they generally take more current 
than is available from a straight logic output to operate them. Most 
BoB's that have a relay, will also have the booster circuitry to operate 
that relay, but that might not be wired to pin4.  So show us a schematic

[Emc-users] Triggering an external relay from a BOB

[Dan Henderson]

Hello everyone, I have a simple question for you. I’m testing the ability
to trip a simple 5v relay with an output pin from a 5 axis BOB and don’t
seem to be having any luck. I have motion-spindle-reverse mapped to the
output pin (04). Was expecting an M4 to go high on the mapped pin and
trigger the external relay. I have 5v+, 5v-, and pin 4 wired to the relay
input side. What have I done wrong here?

Wondering if anyone cares to share with me a useful naming convention for your 
signals? Do you also use the name parameters to name your components or do you 
just stick with and2.0 thru and2.x?

My hal config works fine, but I worry about anyone that might have to look at 
it after me, or even if I have to look at it again after a year or two.

Apologies if this has come up before, I did a bit of light googling and didn't 
find much on the topic.

Shirley (or Roland) you jest. It makes far more sense to clutter up your 
hal files with comment blocks for function headers that explain that, I 
find that I am doing more and more of that as its about the only thing 
that makes sense in a reasonable time frame later. But that also gets in 
the way of copy/paste stuff as I come up with new functions that then 
need copied to the other 3 machines since I'm dealing with two lathes, a 
G0704, and a 6040 here. Each of which has its strong points and 
gotcha's.  And there's only one of me to track all that. :(  I need a 
couple clones, but then I'd have to feed them too.

If so the instructions are incomplete, because I have copy/pasted the

Re: [Emc-users] Hal file naming conventions

[David Berndt]

I guess my biggest issue is I don't name the components themselves. Then  
when I try to describe what a signal is connecting it's connecting some  
terribly named thing, with another terribly named thing, so my signals end  
up not being very usefully named thing like SigNot2And27 or whatever  
nonsense occurs to me at the time. I guess I should start with my  
components and maybe the the rest might fall more into place.

The easiest way to get 2.8 or Master is from the BuildBot:

Its pretty much an individual preference David. I've got some pretty long 
hal files because I'm always figuring out ways to "do it better", and I 
try to use meaningful names for those modules that can be named, but not 
all can be named.  But I've found that going back into it to change 
something a year later, it still takes me quite some time to "get back 
into my own head and figure out what the heck I was doing here", and 
names doesn't seem to be as much help as I thought it was going to be.

OTOH, the wet ram here is also going on 86 yo, and I've had some medical 
problems that have also had an effect on that wet ram that in 1946, 
tested at 147 on the Iowa test, and made a 98 on the AFQT in the middle 
of Korea.  Most notable was a pulmonary embolism when I was 79 & those 
things have about a 2% survival rate, and I am a long time DM-II 
diabetic so I had my heart worked on this past winter after a heart 
attack.  Pacemaker, Bunch of stents and a new Aortic valve.

I think now, that just appending the function its involved in to its 
basic name may be the most helpfull later. But I've not always done 
that, which results in unseemly mutterings later. :(

I agree, there ought to be an obviously better way, but I am not 
convinced I've found it yet.  Rebuilding those modules that cannot be 
named, to allow that would seem to help, but some really are legacy 
modules and how many bugs would be induced doing that today?.  Working 
code I am convinced, ought not to to be played with just for that.

Stay well and safe David.

Cheers, Gene Heskett
