Been doing it that way for almost 20 years now. Other than the NAT to my

Nope, no wifi in their modem. It faces a buffalo netfinity that been 
reflashed to dd-wrt, and it then feeds the first of 2 switches here. I 
wouldn't have it on the premises if it had a wifi.

I probably should update the router, its been about a year since the last 
one.

He's not "cracking" your key, he is just getting access to your router.

What router is it?  Some of these "residential" routers, when you
change your admin password, the old default one still exists.

Also, if you access your router over wifi itself, you'd be at risk. If
you're using HTTPS, you'd have top replace the SSL certificate in it,
because if you're using the defalt one that comes with it,  he'd know what
it is and can basically see all your traffic.

I use a separate (small business) modem and (wired) router for that reason
and only access them over ethernet (not wireless) just for that reason.

just my 2 cts,

Must be some exploit in the WiFi router you have. If you're using the WiFi 
built into the modem from your ISP, ask them if there is a firmware update they 
can install or if they have a newer model.If not, then get a new WiFi router 
with up to date security and daisy chain it off your LAN.

That would work, except I've a neighbor that bought some sort of a

Suggestions for a good one to buy Peter?  The usb-wifi's I have bought 
have generally been a waste of money. Too much neighborhood interference 
I think. I've not scanned recently but found over a dozen usable signals 
from the shop building in the upper rear corner of the back yard a year 
or so back. Thats way too many in a 2.4 gig band.  Gotta be connection 
killing interference.

I'd use a USB WiFi dongle for the software upgrades or any other
internet access, and use the ethernet port to control the 7i96.

If you don't want your CNC machine on the internet most of the time,
pull the WiFi dongle.  I use my phone as the hotspot for my WiFi
connected CNC machines.  It's very convenient, secure, and it avoids
stringing Cat6 cable around the shop.

At $120, the last 45 being the ethernet socket, its still more than a 
5i25 and a SainSmart Bob.  Not by much, add the 2nd BoB to the 5i25 and 
its higher.

Can that work thru a switch and maintain some modicum of decent latentcy?
Since very few, and they are getting old, computers have 2 ethernet 
ports, and I consider a net connection a pre-requisite if for no other 
reason than keeping the machine up to date easy, I have tended to play a 
Sam Eliot about ethernet cards. Hence the question of will it run thru a 
switch so a local network can also work and still run the machine well?

You might want to look at the Mesa 6i25. It's not a parallel card, but
it can behave like one.
The onboard FPGA can generate step pulses and count encoders at MHz
frequencies, though.

Well supported by LinuxCNC.

I'd argue about the diff in cost. A 5i25 is still about $60 more 
expensive than an EPP parport, card.  The 7i90 for pi based stuff is 
roughly comparable to the 5i25 for wintel stuff, but it really needs a 
trio of 7i42TA's to make it useable as I don't consider the 7i90's 50 
pin scsi sockets at all useable. The 7i90/7i42TA combo is a more capable 
combo. The 7i42TA's not only snub the noise that can and has blown the 
7i90's, they also supply easily wired terminal strips. But that does put 
the 7i90/7i42's at a bit more than $200. You do get a lot more control 
lines though.

So the $25 parport card, driving a $23 SainSmart BoB, is still about the 
cheapest starter kit around. The SainSmart has no speed limiting 
opto-isolators in its outputs, a huge advantage as the stepper drivers 
seem to include those anyway. I can't say the same for its inputs, but 
in case you've a very high speed encoder, they are easily bypassable by 
anyone who can trace the circuitry.

I had good luck with a startech card a decade or so back but eventually 
bought an ARK with a D525MW mobo in it, worked even better. But that 
card in an old pc served me well as I was learning for several years. A 
rosewell card didn't work near as well. All yonks ago of coarse.

thanks!!


from the answers I get is that  pretty much anything from a renomated 
brand, that supports EPP/ECP would work.

I use Syba PEX10005 cards with my FPGA controller boards, they seem to 
work well with a wide

variety of motherboards.  They are also relatively cheap.

Re: [Emc-users] parallel port picie cards

2019-12-03 Thread R C

ok,  sounds right.


I (for now) want to get two paxton/patterson machines (mill and lathe) 
going again.  hey would need some special cabling, but figured that out 
a long while ago.



Once i have that going again,  I want to use a better controller/driver, 
then the ones built in.



(I can show two pics if anyone is interested).


I want to use linux-cnc, either Debian 9 or 7 (I managed to install 
Debian 9, the newer one?)

You only need fully EPP compliant if you are connecting it to an FPGA
like Mesa.
