Hi Yang,

Can you write clarly what you want to do with EMC ?
I have some experience with addintional kinematics to EMC.

Michael

[Emc-users] Netless Updates

[Ed Nisley]

This just in from the Linux Journal New Projects section 
(and Department of Passive-Voice Verbiage):

Keryx -- Packaging Solution for the Net-Deprived

http://keryx.betaserver.org/

"The Keryx Project started as a way for users with dial-up 
or low-bandwidth Internet to be able to download and update 
packages on their Debian-based distribution of Linux. 
Mainly built for Ubuntu, Keryx allows users to select 
packages to install and check for updates and downloads 
those packages onto a USB key."

Reading between the lines and checking the website, Keryx 
sounds like it's just slightly to the left of 
alpha-quality, so it's probably not suited for utter EMC / 
Linux / Ubuntu novices. However, if you already know How 
Stuff Works and simply want to schlep all the 
requisite .debs out to the shop in one go, this might be 
the ticket.

Reading the article (from the January 2009 issue) online 
requires a subscription as of right now:

Re: [Emc-users] kinematic

[ygdan1001]

Hi, Michael.
I want to do a control system of PKM with EMC,but there is no real object. Just 
do a system which can control the motor.I should compile some file. But my 
computer can't surf the net, the CVS can't install, and I can't get the source 
code. In this case, I download the directory in tarball to the Windows and copy 
them onto the CD.And put them into the home folder of Ubuntu.
I have the inverse transformation and compile the trivkins.c and the emc.ini in 
my EMC, but it doesn't work. Do you think I did the right thing? To a 
kinematics module, which files I should compile?
I'm much obliged to you for your help.
Regards!

Re: [Emc-users] Coppercam

[ad...@mmri.us]

I used to be on Eagle's usergroup years ago.
It seems to have developed quite nicely.
I already have 3 expensive schematic editors, nonewhich will output gcode.
Really crazy.
The most cost effective way for me would be to rather get a separate
application that will just read the gerbers and produce a routing
toolpath from that.
Eagle is exactly what I would have bought if I did not have all the
other expensive schematic and routing applications already.

Re: [Emc-users] Coppercam

[Jim Register]

Mark,

Searching for "schematic editor" doesn't find it, but searching for 
"schematics editor" returns three pages.  Searching for "schematic" does 
return the page.  Apparently, the search engine uses "exact phrase" 
matching by default, rather than parsing the search string into two 
search terms.  I got no results when entering the search string with quotes.

[Emc-users] Mesa 7i43/7i33/5i20 questions

[Roger]

I'm thinking about buying a dead VMC and converting it to EMC using Mesa boards
and existing analog AMP's and encoders and had some questions:
1. Is there any advantage or disadvantage to selecting either the 5i20 or 7i43
boards? The 5i20's PCI interface is probably more robust but people seem to be
successful with the 7i43. Is there any difference in function?
2. Is the 7i33 quadrature board compatible with the 7i43? It doesn't mention it
in the Mesa documentation.
3. If you need more I/O than a single Mesa board can handle can EMC support
multiple 5i20's or 7i43's (assuming enough parallel ports) or a mix of the two?

Since you can't connect to the internet and have to transfer everything
through a windows machine (shudder), the very first thing you should do
is make sure that windows didn't bork up all the files.  Make sure that
you can compile EMC2 and run the standard sample configurations BEFORE
you change anything!

The 5I20 has 50% more I/O and will have less CPU overhead as it can be 
accessed faster over the PCI bus than the 7I43 with its EPP parallel port 
connection.The 5I20 is twice as expensive however. One advantage of the 7I43 
is its mountable outside of the CPU case which may simplify wiring.

PCI is more robust than EPP but the 7I43 seems pretty good at getting along
with most parallel port on mother boards and add-in cards, see below

Yes, all of our daughtercards work with all of our 50 pin connector FPGA cards

Here are my 7I43 EPP test results so far:


7I43 EPP tests:

Motherboard Parallel port Southbridge or SuperIO:

MOSCHIP 9805Does not implement EPP correctly, no hope
This seems to be true of all 98XX cards

SUNIX 1888  long test >3X10^10 EPP ops error free
 will not work with 12' cable ok with 5' suggest <2 feet

LAVA MOKO S1long test >3x10^10 EPP ops error free (fastest card!)

ITE 8875Trying to figure out how to enable
 (comes up with all ports disabled)

PCIE ADD-IN

MOSCHIP 9901Waiting for card

Testing done with:

12 foot IDC flat cable, December 2008 firmware, Rev C 7I43 hardware
except Sunix card (wont config or loopback test with 12 foot cable)

Rev C hardware is:

1. Rev B 7I43 with 4 SMT capacitors soldered on back near
parallel header

2. Rev C 7I43

Note: I do not suggest using a 12 foot cable, but wanted a worst case cable for
testing. I suggest the Sunix cards be used with a short cable (2 foot or so) 
as they have limited control signal drive

It is working just fine Donnie, but the above question IS your first post.  If 
you sent another at some point, the hounds must have eaten the postman cuz it 
didn't get here, or it is older than my expire settings for this mailbox, 
which is set for 183 days.

Now, what was your question?  I may not be able to answer it, but the authors

Sorry to hijack the thread, but is this an "Arty-style" disable, like 
Sasa Vilic reported on emc-users recently?

If so try to poke it via sysfs or setpci to enable it before accessing it.

No, I think I/O was enabled, its just that the 8875 has some global port 
enable register, and I cant find any chip docs, and since I'm testing with 
DOS, its a little tricky to poke at all the right places to get it to work.

Those tricky hardware manufacturers, eh?  ;-)

The Linux parport driver has a special section for dealing with the ITE 
8872, maybe it'd be applicable to the 8875 too?

See line 2442 of parport_pc.c:
