This will also happen if you change out an ethernet card or 
dongle, and it detects the MAC address has changed.

Same fix for it, too.

[Emc-users] 7mmx1.0 decently hard cap screw, how scarce are they?

[Gene Heskett]

Greetings all;

Trying to hold a 10" diamond saw blade yesterday, tight enough to keep it 
from slipping, I striped out the 6mm threads in my arbor.

So today I bored it gently out to around .230" or 15/64's and re-tapped 
that to 7mm x1.0.  It wasn't until I was cleaning that up that I 
realized I had not seen any 7mm x1.0 screws on my side of the planet.  
So I assume that I may as well redo it for an 8mm screw tomorrow.

But that will be loads of fun because with the 7mm tap in the chuck, I 
had to keep asking for a smaller peck per stroke because even in low 
gear, and the current limit in Jon's servo amp set to limit at about 15 
amps, 150% drive for that motors nameplate, I was raising the divider 
that determined the additional stroke per peck until it was taking at 
least 7 or 8 pecks to tap one additional mm deeper.  Combine that with 
the tap I was using have a longer that normal nose taper, I hit the 
bottom of the hole and that locked the spindle so I'm standing there, 
noting the spindle had stopped and jon's servo amp was singing as it 
overload regulated.  Stopped lcnc, loosened the chuck to release the 
tap, ran the head up 6" or so, and unscrewed the tap from the hole.  
Threads look great, but I suspect there is not a 7mm cap screw about in 
these here parts.  Pure unobtainium comes to mind for the alloy. :)

So, just out of curiosity, are 7mm bolts really that hard to find, or am 
I looking in the wrong local stores?

NAPA perhaps?  Pricy there though.  Seems metric in the label makes them 
an additional $2 a bolt or nut.  Been there, done that. Should have 
gotten a free t-shirt for the price I paid for a 6 pack of 8mm self 
lockers. Bah.

Home Depot, up in Bridgeport, 26 miles up the Super-Pot-Hole, aka I-79 
has the best stock ATM, but I cannot recall seeing any 7's. 8's I can 
probably get locally at Tractor Supply.  In a decent alloy even.

I also think my 8mm tap is a lot sharper than the black oxide finished 
7mm is, so maybe I can get by driving it with the mill.  We'll find out 
tommorrow.

Thanks everybody.

Cheers, Gene Heskett

After some days of fiddling I just got some dated thinkpads (X60 and X61) 
working quite nicely. I had to use smictrl, because the thinkpads special keys 
are somehow hooked to SMI and give a spike when pressed. Also Xorg had to be 
persuaded not to use the intel video driver. And at the end I found that some 
harddisks cause problems: Hitachi work fine, WD gives spikes (400us on X60, 
50us on X61). Now I have a latency of ~ 6us on X60 and ~ 15us on X61, which I 
consider quite OK.

It probably depends on the lathe. It is safe with my Chinese lathe,

Putting a useful limit in looks to be the hard part.

I expect to put an estop switch on my tailstock, and home close to the
"tailstock end" of the lathe, for those times when the tailstock is locked
too close to the headstock. (better to estop on stupidity than destroy
something, or loose position, right??)


My Unimat CNC homes at the tailstock end, but no tailstock, but for my
larger lathe (whenever it comes up in the queue to finish...) it will have
the tailstock.

Homing the lathe at headstock end seems like it would be courting disaster.

Multiple configs doesn't really help, as I only have one sensor. I

more, but I would much rather not.

Or were you meaning configs with different soft-limits and relying on
them, with one general-purpose home sensor?

Re: [Emc-users] Copying an installation

You might give Clonezilla a try.  Burn it to a  USB drive, Boot from that
drive then generate an image on another USB, hard drive, or whatever.

Checkout clonezilla.org for details.  It can also work over a network, but
the devil is in the details, as always.

The resultant drive should be bootable.

The only problem I've had with just moving the drive, is convincing udev 
to leave the name of the eth0 port the hell alone. Everytime you move 
the drive to a different box, it thinks the discovered ethernet port(s) 
are new,in addition to the old one and renames them to something from a 
comedy central movie might use.  ISTR I did something, like nuking a 
file in /var that contained the discovered data of the old port, and 
rebooted.  Lemme see if I can find that file again... brb. Yes, although 
it could be subject to a 
re-write, /etc/udev/rules.d/70-persistent-net.rules

gene@GO704:/etc/udev/rules.d$ cat 70-persistent-net.rules 
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.

# PCI device 0x14e4:/sys/devices/pci:00/:00:1c.4/:03:00.0 
(tg3)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", 
ATTR{address}=="00:1a:a0:a7:a8:d4", ATTR{dev_id}=="0x0", 
ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

Note the comment in front of the line starting with PCI. You will have to 
be sudo or root to change it, but that seems to be udev's memory of 
discovered previously net interfaces.  Humm, checking my other machines 
with never before used HD's in them, that line is also commented out.  
So this may not be the file to play with.  But its a place to search for 
I think.  Or one can search thru the dmesg file, get the name it 
assigned, and edit the /etc/network/interfaces file to match, that works 
also.  I have done both on the G0704 install as that drive was in 3 
boxes before I found a usable box.  And udev bit me in the rear each 
time I moved the drive, requiring that, since my network is less that 10 
machines total, is /etc/hosts file based, nuking Network-Manager, 
making /etc/resolv.conf into a real file and making the correct entries 
in the /etc/network/interfaces file.  That formerly problem machines 
eth0 stanza looks like this now:

iface eth0 inet static
address 192.168.71.10
netmask 255.255.255.0
gateway 192.168.71.1

Substitute your own ipv4 addresses of course.

A convenient tool or method for creating an image of the whole installation (OS 
and LinuxCNC) and packing it up is probably the choice then installing several 
computers of the same kind. Then using different computers I guess you have to 
run ordinary installation although possible with some kind of configuration 
file to tell which packages to install.

The linuxcnc configuration and data files I think you just copy. Then doing 
backups I usually copy data files only, it use a lot less space and I do not 
expect to keep same computer anyway if old computer break down.

It should be very reliable.  There should be instructions on 
the net on using dd to do a block-level copy.
Just make ABSOLUTELY sure you know the names of the two 
drives, or you could copy the blank drive to your only copy 
of the good one. dd can even copy the partition table.

Thats rather a neat idea Dave. How subject to being mechanically fouled 
by swarf is that?

Thats why I "hid" my switch under the back flange of the top of the bed, 
and a rear carriage gib bolt head hits it, lots lower chance of its 
being fouled by swarf. In over a year, I don't recall that it has 
miss-homed that I am aware of...

[Emc-users] Copying an installation

[Danny Miller]

So as per previous thread, I may be moving this to another PC.  And 
probably change to an SSHD.

I spent a ridiculous amount of time getting the OS and LinuxCNC RT 
installed and configured.  And I didn't do all of it myself so it's not 
a straight shot to repeat.  I'm just saying if I start from scratch 
again, this will not be a quick operation.

How reliable is it to just copy the entire installation to a new drive 
on a new (different) machine?

On Windows, I've just moved my old drive to a new machine a number of 
times.  But I was foiled when I replaced my AMD-based motherboard with 
an Intel-based MB, no boot.   My LinuxCNC machine is currently on an 
Intel Core Duo, and I might change to an AMD-based machine. Will it even 
be able to boot?  Will it be easy to adapt to an AMD without a full 
reinstall?  What's it take to adapt it?

I was told there's a convenient tool or method for creating an image of 
the whole installation (OS and LinuxCNC) and packing it up.  Is that 
true?  'Cause I sure wish one of those had been on Bittorrent, that 
would have saved my a crazy amount of time.  If it can be done maybe 
I'll do it and put it out there for others.

I have the same problem Andy, so the first thing I do is jog to the right 
an inch or so, before I hit the home all button. My toy used to have a 
backsplash, but it left to make room for the crossfeed motor on the 
rear.

I placed a $0.50 microswitch about an inch from the chuck so a cap screw 
holding the gib strip operates it.  It can't quite get past it with that 
5" chuck mounted, so the error I get isn't running the wrong direction, 
but "can't home when a shared switch is already closed"

I set SW limits about a millimeter from running into the right Z screw 
bearing, and leave about 20mm more travel to the left from the home 
switch triggered point.  I can remove the QC tool holder, and with 
little concern over what might be mounted in the chuck, do a home-all.

X backs away, trips its switch about .1mm from the hard stop, and gets 
parked about 5mm in from there, so its well out of the way for z to head 
left at a good clip looking for its switch.

Thats a neat idea, but how would that be carved up in the .hal file?  I 
wasn't aware that was even accessible to hal.  Not that I have anything 
in the way of chuck changing that could even be called slow change, it 
bolts on, and the nuts are very difficult to access when restarting the 
nuts onto the other chucks studs.  Major PIMA.  Dropped nuts of coarse 
are subject to Murphy's Law about where they wind up, always with the 
least accessible location imaginable as a target.  OTOH, that PIMA is a 
huge advantage in that I'll never have to worry about unscrewing the 
chuck while doing the reversals a rigid tap pecking routine can do. In 
my case, its broken/stripped drive parts as the treadmill motor has no 
problem putting out the power to do the damage. BTDT. Added a limit3 to 
the pid.s command path to gentle the reversals. Yet to be done is to do 
a couple air cuts and record the turn-around overshoot it will do at 
that rpm, and use that as the final stop point modifier so I can let the 
gcode do the calcs so that the final 2 or 3 pecks will hit the zero rpm 
point at exactly the desired depth. Something along the same line as 
the 'spring' cuts at the end of a g76. Fun and games for this summer if 
my back doesn't put me completely out of commission.  Old age is hell, 
put it off as long as you can...

Re: [Emc-users] Lathe limit puzzle

The denford starturn has the switch on the saddle and a sliding member
gripping the bed just visible under the chuck to the rear

So you can put it where you need for a setup

You don't home away from the chuck?

I'm guessing multiple configs is out of the question for some reason 
like it's more fun to be inventive...

The fact that it was exactly every 64 seconds was the clue that prompted 
someone on the forum to identify it as SMI.

[Emc-users] Lathe limit puzzle

[Andy Pugh]

I am trying to figure out where to put the limit/home target on the Z axis of 
my lathe. 
The saddle can get all the way to the headstock if I am using the collet chuck, 
though it doesn't need to. 
If I put on a face-plate then the carriage will eventually hit that. The same 
is true for each of the chucks. In different places. 
I can't figure out a way to have useful soft _or_ hard limits, or a way to 
guarantee that the carriage is parked the right side of the home switch. 

I do have an idea of a way to make the z-axis have absolute feedback. This is 
looking like a good plan for homing but doesn't really help with limits. 

I need an rfid tag in each chuck to change the soft limits on the fly, clearly.

That's certainly valuable information. Once every 64 seconds or once every 
second is equally bad just harder to find.

For stepper generations I have chosen a modification so that positions are sent 
and then receive FIFO is possible. As is now it allows for one full period of 
jitter and it seems to work really well. The steppers are just a small 
sidetrack for me so it would probably be a few weeks before I could finnish it 
off. The same approach should work equally for servos and as soon as I get a 
few hours I will try my servos with same approach.

I have been running an old Xeon server on my lathe for several years now.
It's just about OK for latency, but does need the SMI tweak or it throws in
a big one every 64 seconds. This is an old dual-CPU P3 Xeon in a 1U case.
No point using one of those now that Mini-itx boards exist.

I have an old server intel Xeon, it is used as a server and I did not try real 
time kernel yet. If you happen to come over old servers thrown out it may be 
worth a try, even though I have no idea I suspect they are a little bit 
different built.

A year back someone recommended these on the list
http://www.ebay.com/itm/281991064246
I purchased three and I like them so far.
Decent latency and more than enough processor power for a CNC PC.
