One way to troubleshoot is to swap DIMs or whatever type of memory you 
have and you should see if the memory error moves. Older motherboards 
might have electrolytic cap problems. One time I bought a bag of them 
and replace all on one motherboard.


Series of caps made in China was as fake as CNN news. They stole part of 
manufacturing process from Japan.



Run synaptic, see there is a slightly newer version available under a
slightly different name, but installed, it obviously needs someone 100%
familiar with the map available just to run it.

The msg at the top of the screen is wrong address, 0x99100, 0x8F000

And it reverts to the grub menu in about 5 seconds.


I would remove HDD and test booting from USB memory stick. Eliminate or 
narrow down components needed to see anthing on the screen to find the 
problem.




Anybody have a clue whats going on?
  
Thanks all;


Cheers, Gene Heskett



Good luck,

Oh. Maybe now I understand...
I only posted the word 'link' with the URL embedded, but when I see replies
to my post, for some reason the embed has disappeared and one sees the

Brownouts and power failures are endemic in bad weather here, so bad I 
had a 20kw NAT gas fired installed 4 years back. And although it starts 
and picks up the load in 10 seconds or so, the damage to a computer may 
well be done before an incandescent lamp is dark.

So I'll take the 2gig dimm out and reseat it a couple times, and reset 
the bios to defaults and turn the hyperthreading back off, then see if 
memtest86 will run.  If not, I'll check the other supposedly identical 
box as a src of supposedly good memory. But its out in the shop building 
at about 40F. So that won't get done this evening. This is the short, 
fat sticks that lay well down like used in lappy's. 2G's worth in both 
boxes.

Thanks Przemek Klosowski.

Memtest boots and runs as the only program on the system; 'revert to grub'
is probably memtest crashing and rebooting the system.
I have never seen it behaving this way: even with bad memory I have only
seen it report errors while still running.
This may be actually good news: it's possible that your memory is so bad
that even the tiny region from which memtest runs is hopelessly corrupt.
Did you try re-seating the DIMMs? If that doesn't help, get new ones and
swap them out. It's possible that the memory controller went bad, too..
What was the history of the system---it worked fine and started
miisbehaving recently without anything else contributing (like
brownouts/lightning/fat-fingered nephews/BIOS battery dying and scrambling

Re: [Emc-users] Easy use of a 2 line URL [Was: Re: DIY CNC builder dilemma, open request for comments

2019-02-20 Thread John Dammeyer 
To make that long URL for me I have to first edit the message with Outlook 
2010.  Change it to HTML.  Save and then hit reply.  Doing that keeps it 
intact.  Doing a reply while it's plain text inserts max line length to about 
76 characters.  I've changed the parameter for Outlook that is supposed to fix 
that but it doesn't seem to work.
 
So I guess if I do post a long link I need to make sure I'm doing this with 
HTML.
 
BTW, Chris, what are you doing with the small module?

Thought maybe I'd see if my memory (in the machine, I know /mine/ is 
shot)
was getting finicky. And the uptimes on this D525MW board haven't been 
that great recently, but I reboot and choose memtest86 from the grub

about 5 seconds.

Run synaptic, see there is a slightly newer version available under a 
slightly different name, but installed, it obviously needs someone 100% 
familiar with the map available just to run it.

The msg at the top of the screen is wrong address, 0x99100, 0x8F000

Re: [Emc-users] Easy use of a 2 line URL [Was: Re: DIY CNC builder dilemma, open request for comments

2019-02-20 Thread Chris Albertson 
About these long URLs,   It depends entirely on the reader's software and
you have no control over what people use.  Some people might even be people
using 15-year-old Windows  XT system.  And many others use Android phones.
  You just can't know.

The technique that works for the most number of readers is to shorten the
URL by using some forwarding service like tinyurl.com
or do what I just did with the above link.   Send the message in HTML, not
plain text.   Then HTML allows you to display the text of a link using
different text then the URL.  So, for example, I have posted the above
link like this: Tiny URL  and it goes to the same
place.

Here is a particularly nasty URL for some parts I bought recently
https://www.ebay.com/sch/i.html?_nkw=stm32f103+us+ship&_in_kw=1&_ex_kw=&_sacat=0&_udlo=&_udhi=&_ftrt=901&_ftrv=1&_sabdlo=&_sabdhi=&_samilow=&_samihi=&_sadis=15&_stpos=90278-4045&_sargn=-1%26saslc%3D1&_salic=1&_sop=12&_dmd=1&_ipg=50&_fosrp=1

The link below may look better for most readers.  I converted the above
link to GRAMETRICAL ENGLISH.   This is a better form, well it is if your
reader supports HTML links and as I said I can't control that.  You may not
care about the part I link to, just an example of how to best tame ugly
URLs.

Hi, I've been using this little part
in
most of my new designs whenever The price is right and it is very versatile
and reliable.

I suggest doing the above as it results in the best readability.

Thats good for a plus 10 right there Lester. And this 6040 I'm building 
up at the moment is a perfect example. Mechanically its pretty good, 
particularly the extremely low backlash. Electrically its a piece of 
shit. Using the cheapest smart driver yet, the TB6560, obviously  peak 
current adjustable but absolutely no docs, its preset, and its designed 
to be driven by mach3. "its preset", yeah, sure. plug in the 4th axis 
and the current is obviously too much as the motor is burn you hand hot 
in just about 10 minutes, and the 24 volt power supply that runs all 4 
motors is folded back to about 14 volts  Rather that putz with that, go 
get the 4 driver kit thats been running the failed HF mill for a decade, 
turn the A driver current down to around 2 amps because the motor looks 
that small. Works a treat and doesn't heat the A motor any worse than 
the others now. Might be able to turn it back up one step. Nothing 
stamped on these motors at all, nothing in the Engrish instructions but 
how to make mach run it, but they are being moved 10x faster than the HF 
mill ever moved in its decade of pushing it past 10 ipm and getting 
stalls. And I had to make dampers for it to get it past 4 ipm.

It has a 110 volt vfd, rated for a 1500watt water cooled motor, so 
obviously the single phase filter cap won't last much longer than the 
bearings in the motor, meaning both will have to be replaced with higher 
quality stuff inside of a 2 year time frame, by which time "they" intend 
to sell me a new one. There are terminals on that vfd to interface it to 
a spinx1 or similar control, one of the reasons I'm using the 5i25-7i76 
combo as I believe I can control it using its vfd interface. But in 
feeding it a raw pwm signal I found the pwm must swing a full 10 volts 
in order to get the full speed range. A 99% duty cycle 5 volt signal 
only gets around 5400 revs, or around 18% of full speed.

And I had it running backwards for several hours with zero ill effects in 
my poking around so I know I can run it backwards with the correct hal 
configuration.  All of which is present in the mesa 7i76 card once I get 
the 2nd one built up. The box I put it all in needs to be 1/4" deeper to 
fit the mesa card, but the  panels on the first one do bulge a bit when 
bolted in.  The 2nd one will have a bigger cnc4pc C1G version-4 card for 
the 2nd bob, which will crowd the 2 power supplies so thats todays 
project, make them fit inside the box. I suspect that will mean jacking 
up the cards another 3/4" inch or more to make room under the cards, all 
TBD yet. There is room to do that, and moving the db25 cutouts upwards 
is not a problem so its not a show-stopper. Making longer standoffs 
isn't a problem other than the raw materiel.

So I am 100% in agreement with

Selling 300 units at $500 each would only recover the $150K R if the
supplied hardware were free with no advertising/support required for the
sales. I suspect that needing to sell 3000 units is closer to reality.

And I realize this is not the majority opinion.


The main problem here is that to China the rest of the world IS a 
minority market. The cost of translation to even just English is 
something they don't need to bother with WHILE they had sufficient sales 
in country, and the likes of newker-cnc are producing turnkey systems 
rather than parts we can use. The major flaw with ALL of this is that 
this kit is designed to reduce the reliance on the very commodity that 
was cheap in China and the rest of the 'developing' world - people? And 
it's the same problem the world over? The automotive sector which is a 
majority market for this kit just like the steel and other raw material 
industries below have more capacity than customers able to pay the 
prices? The days of buying a new car every couple of years just like a 
new phone, laptop and even mill or lathe are a thing of the past and 
it's time to make all of these disposable turnkey products into 
something that can be 'upgraded' which needs to be addressed, so we can 
add the latest improvements to last years kit without having to ditch 
the whole lot. Mine and the wife's cars are 10 years old - and Korean - 
and still going strong - my son bought a UK built Range Rover which has 
been off the road for months while he tried to find a new engine because 
the old one had failed with a 'problem these engines just don't get'.


Unless we can make money from this kit for many of us it IS just a hobby 
activity? So paying inflated prices for the core components has to be 
justified when one can buy turnkey packages at a tenth the price knowing 
one will probably spend another tenth improving things ... which is 
exactly what I did with the 3D printer. And the basic kit from china was 
a quarter of the price of the same kit being punted under the banner of 
UK MANUFACTURE when it is nothing of the sort! The likes of Amazon and 
eBay need to be made liable for the fraud that they hide from customers? 
But we need more openness from all of our suppliers so we can make kit 
last longer.
