Yes it will be cool.  Linuxcnc is absolutely amazing!

Feel almost like Tommy.  Just keep buying machines lol.  But retrofits are
fun and they pay for themselves on the first few jobs so why not.  I want a
horizontal cnc mill now that I can turn into a full 5 axis with rotating
head and 4th axis on the table.  That would be cool.

And it would be cool to explore the possibility of linuxcnc controlling a
dual spindle lathe in the future.

That'll make for one nice workshop.  You should be able to take on 
pretty much any job that'll fit in your work environment.  Good to see 
the old iron being put back to work with a modern controller.  Good luck 
in your endeavours!

Thanks Mark.  Yes pretty blessed here.

Feel almost like Tommy.  Just keep buying machines lol.  But retrofits are
fun and they pay for themselves on the first few jobs so why not.  I want a
horizontal cnc mill now that I can turn into a full 5 axis with rotating
head and 4th axis on the table.  That would be cool.

And it would be cool to explore the possibility of linuxcnc controlling a
dual spindle lathe in the future.

Yes I wondered that Andy.

Pncconf only had options for the 7i77 on first header. So I used that one.

I got it lol before anyone takes the time to help me out..  I better post
back that I have sussed it.

I was using a ethernet patch cable and the wires were swapped.  I found out
which ones changed them and can see the 7i84 now

Re: [Emc-users] Quick question on connecting up Mesa cards

[andrew beck]

hey guys

having trouble setting up 7i84 now.

so I have a set up with a 6i25 and 7i77, 7i76 connected

I am trying to connect up the 7i84 to the tb6 connector on the 7i77.

I have the bit file 5i25_7i77_7i76.bit loaded into card

just getting stuck now.

7i84 doesn't load up.  jumpers are both left hand side which is default.

I am looking for the 7i84 in the hal configuration and can't find it  there
is a sserial drop down menu but it doesn't show the 7i84

I am pretty sure I have it connected up.  before I go back and check my
wiring I just better ask is there anything software related that could be
messing me up?

I have 24v powering the 7i84.  and the CR6 led (field IO error led)  is
showing red.  based on my research this could be because the watchdog is
not petting it or could be a deeper problem.

anyway any ideas sing out  I am stuck lol.


the first time I do anything on cnc it takes ages lol  the second time it
all takes 10 mins

regards

Yes, and yes. Particularly if the supply is a stout one. A 5 volt 5 amp 
like I run my rpi4 with worries me as it can destroy quite a bit of 
stuff. I use 12 volt field power but those switchers go into overload 
shut down at about 2 amps. Even that is enough to cook things if 
something goes aglay.

> If I have broken it that would be a bit sad haha

Considering the cost of a 7i77, I'd terminate the above with a frownie.

I think it may have some protection against reversed polarity, but don't 
quote me. The minus sign on lots of dvms gets hard to see when the 
window gets scratched up. I've not knowingly tested that. Read the pdf 
docs from Mesa, it should be noted if it has some reverse protection.

Good idea, you can test it for sseriel com without having to hook up any 
i/o, just the cable from the5i25 and if not powering from the 5i25, the 
+5 volts.

Its why I buy 3 cards if I'm going to use two. My wiring practices 
haven't always been as neat as they should be. While working on the 
contact holefinder, I was bitching, on this list, about the epoxy paint 
making very iffy grounds, but I found the heavy braided strap that 
supposedly grounds the frame of the 6040 to the electrical ground bar, 
didn't quite reach the ground bar. It had come unplugged from the tunnel 
type screw terminal and was just laying there about 2" away. That was 
all built while standing on the top step of a 4 foot stepladder as all 
its electrics are on a 2x4 shelf hanging from the ceiling on plumbers 
friend above the 6040. And nobody my age, 86, has any business that far 
up on a ladder. That is what folks keep telling me, for my own safety of 
course. :)

With the shack gone, I've been reduced to making simple boards on the 
milling machine. That works, but tends not to be adequately documented 
by me, leading to what the heck was I doing there? questions 2 or 3 
years later. The little one power v-fet board that runs the mister pump 
on the 6040 is one such example. :)

If its a ribbon cable, that doesn't mean squat. Failure IS an option.

And way too many designers forget to treat it as a transmission line. 
Improperly terminated, anything over a foot ought to be terminated in 
125 or so ohms or it rings like the liberty bell. The theoretical 
impedance is about 132 ohms for such cabling.

I don't know if you worked it out, but the 5i25_7i76_7i77 (etc)
firmwares _do_ need the cards to be on the designated headers.
That is why you can find a 5i25_7i76_7i77.bit and a 5i25_7i77_7i76.bit

Simplest is to chop one end off of a Cat5 cable, strip back the cores
and wire into the Smart Serial port on the 7i76.
(I am pretty sure that the 7i76 manual says which terminal block it
is, and which wire goes where)

Re: [Emc-users] Quick question on connecting up Mesa cards

[andrew beck]

hey everyone

just another update here

the latest is I got a brand new mesa 7i77 out of the box and tried it and
that didn't work either when connected to the 5i25 that I have been using
for testing

So I decided to swap the 5i25 out and use  6i25.  I flashed the 6i25 with
the correct firmware and everything worked fine.

then tried the old 7i77 card and it worked fine too.

then connected up the 7i77 and 7i76 to the 6i25  everything works

the 5i25 works fine when using only 7i76 cards which is what was originally
in the board

so my conclusion is that I must have a older 5i25 (it is 3 years old)  and
maybe it needs the firmware updating  I have read that the older cards need
a hard reset

just so happy I haven't blown up any cards though.  and so glad that peter
(mesa) decided to protect against putting the 5v control power on backwards
lol

Now I want to update the firmware on the 5i25 so I can use it also as I
need it for another machine I have here (the second VMC)

and want to try out the 7i84 I have and see if the smart serial works ok

any thoughts guys?  whats the easiest way

Re: [Emc-users] Quick question on connecting up Mesa cards

[andrew beck]

ok just did some more testing

I have two 7i76 cards connected up now and everything works  (using second
connector on 5i25 for extra 7i76)

I am wondering if I have broken the 7i77 I have which I ran 5v backwards
through.

is this possible to do and if it is would I expect a communication error as
a result of it?

If I have broken it that would be a bit sad haha

Re: [Emc-users] Quick question on connecting up Mesa cards

[andrew beck]

ok just did some testing

when I flash the 5i25 with this 5i25_7i76x2.bit file it all works fine

this is just with the 7i76 connected up

when I try to connect up the 7i77 and flash this bit file
(5i25_7i76_7i77.bit)  into the 5i25 I get a issue

the 7i77 is coming up with a red led though in CR16  I read in the manual
that this goes red when there is a communication error with 5i25.

now I have just discovered that I powered the 7i77 with 5v and had the
polarity wrong so was trying to send -5v into 7i77.  I may have stuffed it
I suppose.  all the jumpered are set correctly but I may have created a
problem for myself

any thoughts or ideas sing out.

I have another brand new 7i77 I will try now and just see if that one
works.
.
the existing 7i77 worked last week when I was testing which is why I didn't
double check wiring lol

In my case, yes but I'm only using a 7i76 and a mostly stock bob on my 
5i25, the 7i76 only works on P3, and the bob only works on P2. That I 
believe is determined by the bitfile flashed into the 5i25.

Re: [Emc-users] Quick question on connecting up Mesa cards

[andrew beck]

I have two plugs connected from 5i25

The cable to the 7i77 is a known good cable that was working last week.

I think I might have my cables crossed.  Does it matter which port on 5i25
I connect to which Mesa card?

I'd start by 'ringing' the interconnecting cable, meaning verify the 
continuity of every wire in it.  But Peter may spot a firmware problem.
