cradek: you around?
never mind, I figured it out ;-)
I am now
I was trying to map the same network drive to my real win95 box to simplify moving some drawings
I eventually realized that I was logging into the doze box as john, not jmkasunich
thanks again for the help with networking those boxes
question: am I leaving a gaping security hole by sharing my linux drive?
you don't allow any incoming network connections do you?
the ssh and http ports are forwarded to cvs2 by the router
everything else is blocked
then you can do pretty much anything with little worry
I'm behind NAT and don't worry about it
your real problem is there are not patches for all known win95 problems, and you can get cooties through the web browser
I do very little random browsing with that box
yeah I figured
usually just webmail and a couple other known places
easycad does seem to work pretty well on the VM
it complains that it wants to see 24/32 big graphics, and the vmware driver only supports 8/16, but it seems to work anyway
I'm suprised the vwmware driver doesn't have wider color
what's your X server's depth?
24 I think
whats the easiest way to check?
chris@buster:~$ xdpyinfo|grep 'depth of root'
depth of root window: 24 planes
huh, I'm surprised too
maybe it's a win95 thing
I know that win95 can do 32 bit color - my real box with a Matrox card certainly does
my win2k vmware driver has 8/16/32 bit
you are using the vmware video driver right?
Vmware SVGA II
I wish I knew why vmware sets the VM processes to nice -10
I guess if you are running a bunch of virtual servers on a box, you aren't doing anything important in the "foreground"
but when you are running VMs on your main desktop machine, you don't wnat them hogging the CPU
I think tomorrow I'm going to start some heavy moving
I need to either move the shoptask 6-8" away from the wall, or turn it 90 degrees, to allow for mounting a Z axis stepper
yay, I'm glad you're starting
think you might end up using emc for it?
nah, I think I'm gonna use Mach
you should at least try emc.
ok, if you insist
the sweet potato pies are almost done
first thing I have to decide is how I want to orient the machine
what do you mean orient?
lathe axis parallel to wall, or tailstock end against wall
headstock end needs to be clear, to open the door that encloses the drive belts, and so that rods can be fed thru the spindle hole
I need about 8" behind the bench for the Y (not Z like I said earlier) motor to stick out
full access to the back would certainly be nice
can you move it easily with a palette jack?
no - moving it is a major project
I see why you want to get it right then
getting a pallet jack in the basement would be no fun - the one we have at work probably weighs a couple hundred pounds empty, and would barely fit down the stairwell
my plan is to remove the mill motor, then remove the mill head
take all the drawers out of the bench that the machine is on
that will probably get me down to 500-600 lbs
that's still a lot for you and a few friends to lift
I bet its close to 1000 now
more like me myself and I, and lifting is not in the picture
levers and rollers and such
is it on flat concrete?
fairly flat, and more-or-less level
maybe 1/4" per foot slop
a big guy might be able to scoot around 500lbs on a flat floor
I've moved a 1600 lb lathe by myself
1/2" diameter x 18" long steel rods for rollers
5 foot long prybar, lift one end and insert rod
sounds like an interesting challenge
how did you get this machine into the basement?
took it to pieces
both motors, the head, tailstock, and table all came off
the rest slid down the steps on the pallet it came on (controlled by a block and tackle at the top of the steps)
I really need to do something about the general level of mess down here if I want to be able to work efficiently
I sure know that feeling
I have a PC that is holding up my granite surface plate right now
haven't used (and probably will never use) the PC, its just taking up space
I have a row of 6 or so full tower cases in the computer room at work - they make a kind of table
occasionally I also use one for a ladder
oh they might work, I dunno
they're parts machines
or are they your beowulf cluster? ;-)
nope nothing like that.
this one is a pretty nice case - 19" high (does that make it a full tower?)
no I think that would be a mini tower
full tower is the one that barely fits under a desk
my main pc is definitely a mini - 16" tall
the 19" one is an HP "kayak"
since I always sit the machine next to the desk anyway, I like full towers
at one time it was a gee-whiz engineering workstation
you could put P3-1000 processors in it and have a pretty fast machine
actually it's probably pretty decent as-is
its not crap, but I really don't need yet another moderately good machine
I'd like to have a fsckin fast box - like SWPs dual socket dual core opterons or something
and then run everything else with VMs
in fact, I'm looking forward to getting rid of the cubix rack in the next couple of months
there was a time when I thought that was a pretty cool setup - now its just the noisy thing in the rack
yeah I'd like swp's box too... but he had to put so much work in it
he was on the bleeding edge?
the dual head and the outrageously expensive monitors I can do without
I just want a nice dose of fast
I'm thinking of getting a second screen like mine - they are only $3xx on ebay now
what is yours?
the 2001 dell model (1600x1200 20")
ah, similar to mine
sony 20" 1600x1200
they screwed up the 2007 model, we have some at work
they have some kind of "auto sharpening" built in, and you can't disable it (they say it's to make DVD viewing better), and it screws up subpixel rendering
so I'll have to buy another of the old model on ebay
I don't have enough bench space for another monitor, so I can resist that temptation pretty easily
I will be on the lookout for a nice cheap smaller LCD
I'm gonna mount it right on the machine
seems like they're still $125
(the Shoptask - its gets confusing when we use the word "machine" to mean both the PC, and the thing it controls
I should buy some of these things this year, so I can write them off against the income from the CIM jigs
hmm - $99 for a 15" 1024x768 from microcenter
jmkasunich: I'm pretty happy with the 17" I bought for around $150 -- 1280x1024. it shimmers a bit and it looks like the price went up since I bought it. http://www.newegg.com/Product/Product.asp?Item=N82E16824224007
I have to decide if 1024x768 is enough to run EMC
15" will be easier to mount
we used to make sure axis fit on 800x600 -- I'm sure it fits fine on 1024x768
it only becomes a problem when you are running EMC, and halscope, and classicladder, and a shell or two....
which will only be during system integration
yeah it gets cluttered fast
pretty sure I'd want 1024x768 for a dedicated machine controller
text starts getting small with anything more
looks like the axis main window is 666x597 on my screen, so it won't fit on 800x600 anymore .. not with toolbars anyway
[04:31:44] <jmkasunich> http://www.microcenter.com/single_product_results.phtml?product_id=248359
ugh it's doing something weird when I resize it
gotta pay tax, but no shipping
cradek: are you using icewm or gnome's native wm these days?
$99 after rebate
wow, there was _another_ $20 rebate today only
jmkasunich: sounds like a nice deal if you could still get it
the 99 price is good until 12/3
there are 17" ones for $139 after rebate, and 19" widescreen for $159
I know where I'm gonna mount the monitor
no clue at all about keyboard and mouse
I seem to recall Ray asking on list about how people set up their computers/monitors/keyboards, and didn't get much of an answer
you just have everything on the same table/bench as the mill, right?
it's not a real problem for small machines
chips and oil and general yuck would make that a disaster for me
the only minor problem I've had is the keyboard gets dirty
dirty hands on the keyboard are a real problem, no matter where you put it
trackball might be a better choice than a mouse
both suck in dirty environments
I think the only hope is a glidepoint/touchpad
yeah, but the trackball doesn't need acres of space
you barely need a pointer to run emc
I wonder what "spill resistant" means for keyboards
[04:46:15] <jmkasunich> http://www.newegg.com/Product/Product.asp?Item=N82E16823205001
a buckling spring keyboard is everything-resistant
disposable - $2.92 each
I don't see how anything with membrane switches can be spill resistant
buckling spring is the original IBM technology?
no contacts or exposed conductors at all
not immune to blue-hot chips I bet ;-/
not immune - resistant, maybe
the way I see it, I have to mount it high enough that chips won't fall on it
need a touch screen monitor
but for touch-off you'll want one hand at the tooltip and one hand on the keyboard, so they have to be close.
the hand on the keyboard is for hitting the "here's the right place" key?
or for jogging? - remember, I will have a jogwheel
then it's not so important
if I was a touch typist I could put the keyboard against the wall near the tailstock
but I'd have to turn 90 degrees to use it, and my blind typing isn't that good
sounds not ideal
[04:55:23] <cradek> http://www.daskeyboard.com/
heh, I'd be screwed
I don't have one of these but I used an HP keyboard with scooped F/J instead of "nipples" on the keys - I liked it
I'm forever feeling for the little dots on the F/J keys
I never do - I certainly don't hunt and peck, but I very much look at the keyboard, at least when I'm putting my hands on it
right now my ergonomics are just terrible
the keyboard (and mouse) are on top of the bench, much higher than they should be
33" from the floor
don't you have a normal desk where you do your computer-only work?
[05:00:15] <jmkasunich> http://home.att.net/~jmkasunich/Pics/bench.jpg
I do, so it makes the ergonomics of the workshop unimportant
that is before I got my LCD, but that is my "desk"
no room for legs
yeah there is
ok, doesn't look like much
kneehole is 18" wide
my smallish desk has 25"
I really need something better, but space is an issue
of course, maybe if I cleaned up some of the mess
jepler sits on the couch with a laptop - another possible approach
I've tried that but always come back to the desk
I can't stand laptops
I'm off to try the pie - goodnight
I have just installed the ubuntu emc in my old windows partiion and I have lost my previous BDI setup. Is there a way to get it back?
do you mean that you can no longer boot to it, or that it was erased during the Ubuntu installation?
I am pretty sure it is still there, its just that ubuntu does not give me access to it when i boot
ok. and when you ask about access, do you want to access the files from the ubuntu boot, or that you want to be able to boot the BDI installation?
I'd like grub to show me both systems so i can choose at boot time
I can see the files from ubuntu
I like the ubuntu system very much, but I can't get it to work with my Sherline machine (I don't know how)
sorry - was afk for a moment
ok, so the ubuntu system automatically picked up the partition, and mounts it for you - that's good :)
I'm in ubuntu land right now
if you run the "mount" command, that will tell you what the partition name is (something like /hda2, I'd bet)
ir it's probably in the GUI somewhere, but I'm not positive where :)
/dev/hda1 on / type ext3 (rw,errors=remount-ro)
proc on /proc type proc (rw)
/sys on /sys type sysfs (rw)
varrun on /var/run type tmpfs (rw)
varlock on /var/lock type tmpfs (rw)
procbususb on /proc/bus/usb type usbfs (rw)
udev on /dev type tmpfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
devshm on /dev/shm type tmpfs (rw)
/dev/hda2 on /media/hda2 type ext3 (rw)
/dev/hda3 on /media/hda3 type ext3 (rw)
you'll need to look under the BDI partition /boot directory to see the name of the BDI kernel
ok - check /media/hda2 to see if there's a boot dir there. if not, check under /media/hda3/
the hda3/boot directory is empty
ok, is there one under /media/hda2 as well?
what size are the hda2 and hda3 partitions?
in hda2, I have system.map, configxxxrtai and initrd.img files
and a grub folder
ok. it's possible that hda2 was mounted as /boot, and hda3 was the root partition
(with the empty boot dir for hda2 to be mounted under)
if you look at /media/hda2/grub/menu.lst, that will have the information that you need to add to /boot/grub/menu.lst
sure. if you need any more pointers just let us know
I have changed the file and I am about to test with a reboot, thank you
One more thing, are there known Sherline setups for EMC2 ubuntu? I tried copying the ini files from the Sherline site but emc does not run
The coolcnc iso does not really work either with my mill
the sherline site has EMC1 (or BDI) configs, so they shouldn't work
the closest will be stepper_inch (or _mm)
I am surprised that they aren't upgrading
you should follow the instructions on the wiki for customizing configs on Ubuntu
yeah - they probably should, but who knows ...
I had a look. it seems like a lot of work that can fail easily
I am sure I am not the first guy with that mill
nor the last ;)
So if they can all do it, I guess its not that difficult
I'll have a look, thanks for the help
we could/should make sample configs that are workalikes for the sherline configs
I bet it's just a matter of scale/vel/accel settings
yeah - I suspect the scales are pretty standard for their machines (as well as the pinouts, of course)
yes I'm sure the pinouts were made to match emc1, so our default will match
I don't know if they have an estop button or anything, they might
I have not personally seen their setup
I suppose a look at the ini file would tell us that
I'm not entirely sure how to get it are you?
off the CD?
I don't know if the bdi CD we can download matches what sherline uses
I don't see it on the website
for a while they had their customizations to bdi on sherline.com
they link to ourproject, which links to cncgear
yeah - for 2.18, they say
maybe we should ask the next sherline user who drops by for his
or possibly jmkasunich
(or anyone else who has a BDI 4.xx install)
oh yeah - like me :)
ok you're assuming they're the same
I think the BDI installs two icons on the desktop
ray would know for sure obviously
yes, that's my assumption
well, the BDI was made for Sherline, so ...
maybe tomorrow :) off to bed now
