Re: [Emc-users] Newbie w/mobo question

2011-07-05 Thread Neil
So back for a bit, and have decided to get the D525MW w/1GB of RAM.   
Placing order in the morning.  I completely forgot about this  
CF-to-IDE option, and will prob look into it later, but for now I'm  
anxious to get something up and running.  Incremental dev ;)

FWIW, I have 16 2.5 drives here, of which 3 does not work (kept them  
cause I might've needed the internals to repair some other drive over  
the past years), and 4 in machines currently.  Only 2 of these are  
SATA.  Of all, the WD's and Hitachis have been the most reliable for  
me, so I guess YMMV really applies here.  Always hated Seagate, and a  
year ago I got a Seagate (was on sale and I figured it had been long  
enough), and it died about a month later.  Grrr...

Anyway, thanks for the info, and I'll post updates when I have  
anything useful to show off.

Cheers,
-Neil.

 You can see it when the machine boots up, but it's easier to check it
 on the running Linux system by running the 'dmidecode' program; on my
 machine, it prints the BIOS info in the first record:

Ok, thank You!
I will try to remember to check the BIOS version and latency numbers
for D525MW board, so that they can be added to wiki page.

I have used two different Sata compact flash adapters.

1.  About $40 each - Addonics - model ADSACF.   I bought several 
directly from their website.  Similar to this:  
http://www.newegg.com/Product/Product.aspx?Item=N82E16812174005cm_re=sata_compact_flash_adapter-_-12-174-005-_-Product
2.  About $15 each Syba -  
http://www.newegg.com/Product/Product.aspx?Item=N82E16812186061cm_re=sata_compact_flash_adapter-_-12-186-061-_-Product

Both work well.   The Addonics might be a higher quality unit but I have 
had both running in systems for over a year now.I have one system 
that has been running the Addonics card and the memory card below for 
three years now.

For memory, I tried a couple of different flash cards and found that 
these work well and I have used several with zero issues - about $18
http://www.newegg.com/Product/Product.aspx?Item=N82E16820208340cm_re=compact_flash_8gb-_-20-208-340-_-Product

Boot time is quick, although a faster card might make it even quicker.

So for about $33 you can have a diskless system that is easy to maintain.

For laptop hard drives I have found that these are reliable:
$39.00  http://www.newegg.com/Product/Product.aspx?Item=N82E16822148443

cables, power and Sata, and also a PCI bracket and in the case of the 
Addonics I think it also comes with a drive bay bracket (better check to

but it is his sideline.

If you are interested, send me your contact information off-line and I

WD have had a long term bad rap with me.  Seagate is better, but still no the
absolute.  Various companies hold top honors from time to time, but eventually
old age, technology changes, a bad batch with infant mortality problems, etc
... bad disks come from even the best vendor.  Warranties have also gone down
hill, and they work hard at keeping you from exercising them when something does
happen.  But most vendors, if you have the documentation, will do what they say,
but only just.  Don't expect anything over what they state explicitly.

 D510MO (and its new replacement D525MW) is definitely worth it.
 Costing100USD (and You get both - mainboard and CPU for that price)
 they are very good for the job - latency numbers are pretty nice. I
 have used both of them. Other users also have reported positive
 feedback about D510MO here on the mailing list.
 None of these boards have PATA, but there are cheap SATA HDDs
 available. And adding a GB of RAM will give You a working PC for less
 than 200USD.

Eric:

I agree with Viesturs about the D510M0. I used to have one but turned it 
over to Stuart Stevenson during the last emc fest. I expect to get a 
D525MW or successor for my next project.

Just a couple of points.

First, the parallel port on the Intel D510M0 is not brought out to a 
back connector. You'll have to make or buy a cable that terminates on 
one end with a socket to match the internal connector (see the manual 
for location and pinout info) and on the other end with whatever you want.

According to its manual, the D525MW does have a back connector for the 
parallel port.

Second, there is an error in the BIOS code of the D510M0 that causes it 
to report its parallel port settings incorrectly. The port itself is 
working properly, but software like emc assumes the BIOS is telling the 
truth. Release 2.4.6 of emc2 includes a workaround for this.

Viesturs...do you happen to know if the D525MW contains the same BIOS bug?

Regards,
Kent

 workcell ... http://www.veisystems.com/nose/rw.html .

 Originally we set it up to work with a Mini-ITX motherboard, but it
 does not like Ubuntu.  Since it's an older mobo (EPIA 800), I'm
 thinking I'll just get something more updated, and *proven* to work
 with ubuntu.  But not coming up with much, other than 2 options on the
 hardware latency page.

 Can anyone recommend a mini-ITX (or other small) motherboard that will
 work with ubuntu/EMC2?  I know EMC2 doesn't need any fancy specs, so
 hopefully I can get something for under $100, though more is fine if
 necessary.  Also, would be nice if it supports PATA as I have a number
 of those drives laying around.  Newegg has a number of low-cost
 options, but I don't know if EMC2 will run on it.

 BTW, if there's a doc that has this info, sorry for the post and I'd
 appreciate a link.

 Thanks,
 -Neil.

Neil. I tip my hat to you for working with high schoolers on technical 
matters. I wish more people did. I have spent a fair amount of time with 
several FIRST Robotics teams and I know how frustrating, fun, 
frustrating, and rewarding it can be.

Despite my packrat nature, I'd say dump the PATA drives. There's nothing 
more frustrating than the mysterious errors that start cropping up as 
hard drives begin to fail.

Kent

Cool.  Will investigate.  I do have one SATA drive laying around, so  
that's really no problem -- just considered the PATA since I have many  
of those and as time passes it gets tougher to make use of those.

 From a quick glance, it looks like it has a parallel port connector  
on the board (no back-panel connector), which is fine.  We will  
definitely need parallel for other things, so I have to verify it's an  
active connector.

Thanks,

 D510MO (and its new replacement D525MW) is definitely worth it.
 Costing 100USD (and You get both - mainboard and CPU for that price)
 they are very good for the job - latency numbers are pretty nice. I
 have used both of them. Other users also have reported positive
 feedback about D510MO here on the mailing list.
 None of these boards have PATA, but there are cheap SATA HDDs
 available. And adding a GB of RAM will give You a working PC for less
 than 200USD.

 Just a couple of points.

 First, the parallel port on the Intel D510M0 is not brought out to a
 back connector. You'll have to make or buy a cable that terminates on
 one end with a socket to match the internal connector (see the manual
 for location and pinout info) and on the other end with whatever you want.

 According to its manual, the D525MW does have a back connector for the
 parallel port.

 Second, there is an error in the BIOS code of the D510M0 that causes it
 to report its parallel port settings incorrectly. The port itself is
 working properly, but software like emc assumes the BIOS is telling the
 truth. Release 2.4.6 of emc2 includes a workaround for this.

 Viesturs...do you happen to know if the D525MW contains the same BIOS bug?

 Regards,
 Kent



I just found the same thing here... http://communities.intel.com/thread/12655

And wondering the exact thing about the D525MW.  EMC2 having a  
workaround for it is excellent, but we'll also use this machine with  
WinXP (for some 3D printing software and perhaps Mach3), so it would  
be nice to know the hardware works properly.

Anyone here actually used this D525MW?

 My question too.  Still googling, and have not found anything negative
 about it.

As usual, the posters neglect to tell us vital information, in this 
case, the BIOS version of their D525MW motherboard. I just checked the 
Intel site and found the latest BIOS appears to be 0080 dated 4/29/2011. 
The cumulative release notes suggest a number of fixes related to Linux 
(re)booting but nothing related to the parallel port.

It's distressing that the BIOS bug relating to the parallel port seems 
to have persisted over several Atom motherboard design-cycles The first 
relevant post I saw on communities.intel.com was dated 4/19/2010 and I 
was the only one to reply to it. We never found a way to whack the 
appropriate Intel Product Manager upside the head. The managers 
obviously don't monitor their user site, probably because of the number 
of nasty-grams that are posted.

Somedays I think I should delve into the BIOS and fix it myself. Then I 
take my meds and come back to earth. Of course, another approach is to 
use an add-on parallel port card, but they are getting harder to find 
and it ties up the only motherboard slot.

I still think the D525MW remains a good bet for EMC2. Andy is correct 
that the BIOS bug doesn't matter but some software doesn't know that it 
doesn't matter :-) Fortunately, EMC 2.4.6 does.

Kent

Coming to a similar conclusion.  Mach3 has created a low-level driver  
that accesses the parallel port directly, so won't work with USB to  
parallel adapters, nor most parallel ISA/PCI cards.

However, you're right that Mach3 may not need EPP/ECP modes.  More  
importantly, I am wondering why we would need Mach3 on this machine.   
Any custom software we're writing is in Linux, EMC2 (which will handle  
pick-and-place stuff) has it's workaround, and WinXP is for the 3D  
printer stuff , which uses the serial port/USB.

Think I'm good to go with this.  Thanks for the replies.

 I would consider using the drives you have and set up RAID.
 http://en.wikipedia.org/wiki/RAID

Funny enough, my existing EPIA800 mobo started life ~8yrs ago as a car  
MP3 player, hence the custom power supply.  But the drive crashed on  
hard bumps, so I got pulled into duty as a mini RAID file server with  
2 60GB PATA drives.

I was looking to upgrade about 4 yrs ago so got the 2 120GB drives,  
but never did the conversion.  Hence those two drives floating around.


 In my opinion, for motherboards, try to use what you can get cheap or
 free. I like older complete PC's such as a full or small form Dell's or
 similar.
 http://www.geeks.com/products.asp?cat=SYS
 or eBay

 To me, trying to get a tiny PC (or notebook, laptop, etcetera) to work
 with an EMC2 machine just adds more needless work, unless you happen to
 carry your CNC around in your pocket. Any motherboard I would consider
 would need at least three PCI slots of some variety, so that cheap
 add-on parallel port cards could be used (despite rumors, parallel ports
 are not going away anytime soon).
 http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EMC2_Supported_Hardware
 (see parallel port card section)

Laptops are generally not good for any type of real-time control, but  
my small mobo requirement comes from us trying to make everything as  
compact as possible with the on-board PC.  Would've done a larger mobo  
if that was the only answer, but with a workable Mini-ITX option,  
everything will be nice and compact and will fit in the existing  
enclosure (with only small mods to the back panel cutouts).


 I avoid using the motherboard parallel port, so when I blow up the port,
 I don't have to replace the whole motherboard or PC. ...

Agreed.  For this though, I always use a buffered/isolated breakout  
board.  And also because many parallel ports don't provide a full 5V,  
or very low current.


 ... Another pet peeve, the EMC2 PC should stay with the machine it is
 intended to run. If you need a PC for another application, get another
 PC.

Correct.  This will be dedicated, and installed on the machine.  My  
CNC mill for example runs Mach 3 on a dedicated mobo, all integrated  
nicely into an enclosure with the stepper drivers, etc.

I should stop talking about Mach3 here on this list, especially since  
I'm not going to need that anymore. :)

 Maybe I over-simplified.  It's sort of a glorified breakout.  My
 understanding of the smoothstepper is that it is a motion control card
 (ie: handles acceleration, etc), whereas I don't see that the 7i43
 does that.

I dont think the smooth stepper handles acceleration, basically its a rate 
generator just like the 7I43s stepgen. Acceleration management is not needed 
in the low level hardware unless you have quite slow update rates (say less 
than 1 KHz)

Acceleration would be easy to add to 7I43s stepgen but with EMCs 1KHz update 
rate the accuracy gains are miniscule and the overhead of the additional 
register access would be substantial.


 Cheers,
 -Neil.

 So the Mesa looks like a breakout card of sorts.

 It's rather more than that. The closest equivalent in the Mach3 world
 would be the SmoothStepper, but the 7i43 can do PWM, serial, SPI,
 count encoders, make the tea...

 Neil,
 
 If you are going for cheap, consider using a 8 gig Compact Flash Card in 
 a Sata to CF card adapter.
 
 I have a few running in machines now for a couple of years with zero issues.

I have this on two machines as well.

 I can tell you exactly what parts I am using if you want to go that 
 route.   8 gigs is plenty of space for Ubuntu 10.04 and EMC2.   I 
 believe I have 5 gigs of free space or so.
   
Yes, I'd like to know.  On a lot of these things, there are some models 
that work, and some that cause
problems.

 I do not have access to that machine, so there is no way for me to check.
 BTW how can I do it? I have never tried to find out, what BIOS version
 any of my PCs is running.

You can see it when the machine boots up, but it's easier to check it
on the running Linux system by running the 'dmidecode' program; on my
machine, it prints the BIOS info in the first record:

of my computer)
