Rugludallur_: I have a Geode GX1 somewhere around
gee, and I was guessing Open Linux mumble mumble....
ran emc2 on it a year or so ago
anyone knows wth "dark fibre" is?
alex_joni: Dark Fiber is just a term to describe a fiber line which does not have a protocol specified, so you can run Ethernet or ATM or what ever you want over it
installed but not in use
ahh.. ok.. thx
alex_joni: yes, I drew http://www.robcon.ro/emc/weaving.pdf
cradek: yes, I have a filing system (sort of)
its just a big spreadsheet
in USA in the late 90s, backbone fiber was installed like a gold rush, much of it was never used, only now being "lit up"
alex: how did the paralell port work on the Geode ?
but its incomplete, and suffers from bitrot as I move things around
alex_joni: Great, It would be neat for people to be able to buy a machine for sub 200 with monitor and run it as a machine controller
does the OLPC have a parport?
I thought it didn't
alex_joni: don't think so, but the prototype board I am working with does
alex_joni: the final board is not supposed to have a parport, but .....
alex_joni: I wonder If I can convince them that they might want to do analog control from the machine .......
[00:08:17] <alex_joni> http://linuxdevices.com/files/misc/amd-cs5536-diag.jpg
GPIO might be just as good
Rugludallur_ is now known as Rugludallur
alex_joni, nahh im using a WAFER-LX-800
alex_joni: The hardware people in Taiwan don't have a prototype so I bought the cheepest board that I could get in a week
[00:12:19] <alex_joni> http://www.ipc2u.ru/files/products/32539/wafer-LX.jpg
my old gx1 has pc104, pc104+ and isa :P
and it was twice that price :(
[00:15:26] <alex_joni> http://dsplabs.cs.utt.ro/~juve/emc/mytoy/HPIM5139.JPG
I should probably do something with it.. it's getting old :(
alex_joni: what were you booting off ?
suse 8.2 (HDD)
the ribbon cable at the top
but it has a CF slot on the back
alex_joni: same as mine
alex_joni: I have been working 16 hour days for the last week getting a working kernel with X on 128 mb
alex_joni: booting off compact flash by using a ramdisk
hmm.. why not get a puppy?
alex_joni: how fast is that board?
[00:18:56] <alex_joni> http://www.puppyos.com/flash-puppy.htm
alex_joni: need the extra flexibility that gentoo provides, better hardware support and such, the geode lx drivers are pretty recent
Rugludallur: oh, ok
those are nice and small....
alex_joni: this thing will end up on thousands of units, if not millions so the work can easily be justified :D
they use 220.127.116.11 as a kernel
I'd say that's damn recent
alex_joni: hmm yup, im actually using 19 at the moment but ...
[00:21:48] <alex_joni> http://www.puppyos.com/download/release-2.12.htm
alex_joni: hmm might be easier to strip down puppy than build gentoo
alex_joni: have you tried puppy ?
we have/had a version with emc2 on it
but there were problems with the RT kernel
from what I looked at it, it seemed that RTAI overwrote the ramdisk somehow
alex_joni: hmm thats wierd
probably RTAI didn't care it's allocated (just like it does for memory over 1GB)
alex_joni: gentoo actually has pretty good embedded support, they got a tiny x server and everything but getting everything just right and sorting out the dependencies takes ages when you have to recompile everything
Rugludallur: anyways, if you want to give it a go it's here: http://dsplabs.cs.utt.ro/~juve/emc/get.php?file=coolcncb05.iso
same for puppy as I understood it
some info on that here: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?CoolCnc.0.5
alex_joni: thx, I hope I get to keep the hardware when the project is over, then I can start playing with EMC :D
I might remember parts of it.. so bug me if needed
alex_joni: Great, thanks
anyways, getting late.. good night all
hellooooooooo, is there and echo in here?
tomp: I have this vague memory of you saying you have a shoptask or some other such 3-in-1
is that true, or do you just do EDM?
jmk: got shoptask & small horz mill & 2 sink edms
CNC the shoptask yet?
yes, emc, stepper, pac-sci 400 oz
I'm finally (after years) getting started on mine
[02:01:22] <jmkasunich> http://jmkasunich.dyndns.org/cgi-bin/blosxom/index.html
do you get good results with the 400 oz-in? (fast rapids, plenty of torque, no lost steps)
geez... you cheat, I see FLOOR in those pics
took me a couple weeks to find that floor
nice pix jmk: i dont recall the speeds and the computer was pulled for the stg tests... not very fast.. amp allowed up to 256 microstep, think i used 10
ok, I see a Rockwell varispeed drill press, with an unusual motor setup....
a prior owner installed a countershaft where the motor goes
the thing i was most concerned with was the wiggly quill on the shoptask( broke a few 1/4 and smaller cutters)
the motor drives the countershaft with about a 5:1 step down v-belt
so it goes SLOOOOOW
tomp: yeah, the shoptask is a quite decent lathe, but a rather dissapointing mill
slow... so its not a drillpress, its a reamerpress :-)
and a tappress
between the varispeed belt and the VFD on the motor, it will do about 20 to 1200 rpm
I've tapped 3/8-16 in cast iron just by chucking the tap and going (there is a reverse switch ;-)
wow you took a lot apart
can you move it now?
only a couple hours
mostly pulled off assemblies, rather than taking all the fiddly stuff apart
half the time was probably cleaning crap off
jmk: remember those change gears, the order is not obvious 6 months later ;)
haven't got that far
I need to pull all the drawers out of the bench, etc
tomp: yeah, although they way I disassembled it, there are only three "chunks"
and, I have a picture tucked away somewhere just in case
in the long run, those gears won't be going back in
EMC will be my threading gears
cradek: I suspect it still weighs 300 lbs
plus another 75 or so for the bench, even with all the drawers out
that's easy with a friendly neighbor
neighbors on both sides are female, and one is in her 60s ;-)
ok it would take a few more of them then :-)
it won't be hard to do myself
I'm also gonna be moving the cabinet thats next to it
(the one that looks like a card file)
I keep metal stock in there, its HEAVY
jmk: the tricky bit is fitting the top casting with post back on top, heavy, awkward & above your shoulders
thats what the eyebolts in the joists are for
got a hoist?
I lifted it out without them, but there's no way I could put it back
got rope and pulleys
(I used to own a sailboat)
oh, in the joists, good idea, i had an i beam in this 1900's brick house, i put it right under the beam :)
thats how I got it on the bench in the first place
pallet on the ground where the bench is now, hoist it up, pull out pallet and push bench underneath
tell us about the addition to the milling head
rotating preloaded ballnut
screw doesn't turn, its attached to the banjo
stepper isn't mounted yet, but you can see where it goes on that aluminum plate
k, and the motor mount i see.. so this is the z axis, nice
the original rack/pinion, and that dog clutch, had crazy backlash
0.050 or more
so I ripped it out and covered up the hole
yes, much nicer than what shoptask suggests ( i also had huge b-lash, and no worm either)
what pitch? .2" or less
0.2 I believe
in a couple minutes I'll post a drawing of the quill assembly
jmk: i got hscale working now, and am fiddling with a meter widget for halvcp... wont bother you till this next bit is done
jmk: thanks, i wanted to ask for a sketch :)
there were other shoptack/emc users on the google map, they'll like it too
the drawing isn't dimensioned or anything, I made individual part drawings as needed
and the overall design was made to suit the screw/nuts/bearings that I had on hand
so it won't be directly usable by most folks
but they can use it for ideas
tomp: its posted now
same URL as before
the biggest challenge there was to maintain as much travel as possible but avoid hitting the underside of the spindle pulley
jmk: got it : gratzia mille,,,
so, did you keep most of the original 3.5" travel
i got me a nother project :)
travel is exacty the same as before (bottom end is limited by the screw that keeps the quill from turning, not by the ballscrew assembly
3D model, or 2D CAD, what software?
I could generate a dxf of that drawing if somebody wanted it
have not played with easycad since just after the split with Autodesk
but the whole thing was designed around a surplus ballscrew, so its bound to be different for someone else
I really like easycad
its the only reason I still have a windows box
I have drifted away from regular CAD and do almost exclusively PCB now, when I must do mechanical CAD I force it through VectorCAD/CAM
heh, i keep dos for generic cadd ( gcadd ) also bought out by autodesk
AutoCAD lost me with the "paper space" vs. "real space" mish-mash
steve_stallings: how much is a license of vector cad/cam
figure next time I put out the effort to master a new system it will be SolidWorks or similar
standard 2D cad, plus CAM is US$795
Vector is powerful, but somewhat strange for ex-AutoCAD users
what's the order status?
perhaps 2D is not accurate, it does understand 3D but does not do a good job of real 3D models
where's swpadnos? :(
swp is traveling
the order will be placed somewhere around 12/20 after when he gets back
order planning targeted for 20 Dec or thereabouts
who should we send the individual orders to?
what's the page again?
have we made the 25 sku?
the actual order (payment and such) not determined yet
[02:52:26] <jmkasunich> http://jmkasunich.dyndns.org/cgi-bin/blosxom/shoptask/m5i20-group-buy.html
i already sent it to jmk: thought i had done wrong :-|
the order will probably go thru swp, because he has paypal which lets folks use credit cards if they want
I should make the breakout boards. and resell them. :) but hey... that's just me.
to get listed on the webpage, talk to me
steve_stallings: maybe I should try it
ALPHA, there's 2 web-available designs thata re close to whats needed, one on stg site, other at clemsen univ.
* jmkasunich starts pulling drawers out of things
if you can live with 2.5D there is Sheetcam which works from DXF and only cost US$150, quite good, CAM only
tomp: are those the two that I have links to on the webpage?
SheetCAM, Vector, both Windows only
jmk: no theses are free designs ( pcb designs )... i'm collecting urls now
jmk: 1 is http://www.mech.northwestern.edu/courses/433/ServoToGo/BreakoutBoard/ad/
jmk: 2 are http://www.ece.clemson.edu/crb/ece496/stg_breakout_inst.htm
they could be modified for the mesa card
I'm almost certain the STG one doesn't have the right pinout
steve_stallings: I cant..
jmk: they are 'correct' as correct as the winford would be (i think you could just forget the names )
STG pinout on pdf page 11 of http://servotogo.com/hardman2.pdf
-- it's got the signal pins in different locations than the m5i20
5i20 has grounds on even-numbered pins and signals/vcc on odd numbered pins -- pdf page 6 of http://www.mesanet.com/pdf/parallel/7i37man.pdf
so don't buy an STG breakout board for your mesa
unless it's just screw terminals or something
dang... I'm getting old
thats just the name... use it as you want to use it, it's just a 50 pin hdr to term strip... and you can mount a connector on the other side of the board to fix the odd even problem
the northwestern.edu board is much more than just an adapter to screw terminals .. it's very specific to the STG pinout
oh ehy.. .this guy doesn't even charge that much... $25 http://www.daqstuff.com/50_pin_breakout_500013.htm
anonimasu: for Vector, check out http://www.cadcamcadcam.com/hobby/
- there's a holiday special price.
yes, the nwu board... we'd eliminate a bunch of stuff, better yet dont use either design ,make a new design ( uh that looks a lot like the others, just a little different )
jtr: it's not for hobby stuff :)
damn... why is steel so heavy
jmkasunich: atomic composition contains more protons and neutrons.
I knew there had to be a reason
(beside making my back hurt)
I wonder if magnetism and gravity have something to do with it being more heavy... just even slightly.
like... I've an university science graduate. And that's a serious question... since iron is magnetic... would gravity/magnetism cause it to be slightly heavier than just gravity alone.
I've = I'm
[03:16:03] <jmkasunich> http://jmkasunich.dyndns.org/pics/drawers1.jpg
[03:16:06] <jmkasunich> http://jmkasunich.dyndns.org/pics/drawers2.jpg
it may... as magnetism can do something for compases
depends on how "slightly" you can detect
compass needles orient themselves parallel to the earth's field, because they themselves are magnetized
plain old steel isn't magentized
any effect from the earth's field is very very very small compared to gravity
well... also, there be a north and south pole. so it should equal out.
what's with the toys in the pics? :)
trying to move the machine and the bench its mounted on
the drawers of the bench add a few hundred pounds so I took them all out
who's machined Titanium grade 5?
robin__sz I think..
I really want to make a ring for myself.
so I think I'll toy with it now, after I take a quick shower.
manual machining may not be too much fun.
gold is easier to machine ;-)
gold is SOFT.
and why would you machine it, and not CAST it?
I was joking
jmkasunich: oh. you. are. so. funny. ha. ha.
(my wife is a bench jeweler, I know about casting gold)
I made a ring of stainless on a manual lathe
316 acts about the same as Ti grade 5.
so I've been told.
at least not with a light machine
well, I can move it...
one end at a time
found about 10 lbs of chips behind the bench, more sweeping and cleaning
jmkasunich: yikes. don't you clean up after you machine?
I think they were hidden between the bench and the wall.
yeah, I clean up by scraping the crap off the bench and down between the bench and wall ;-)
I hate that with cnc's..
they make so much chips
one of the reasons I'm moving the machien is for better access
I hung som posterboard behind my lathe, to catch them and redirect into the tray.
works for the oil stripe as well.
I need to get a vaccum/build covers for the slots in the table..
yeah, with the new position I'll definitely be doing somekind of chip deflector
I suppose I should clean the strip off the wall before I move things up against it
Did you ever have a problem with the cat getting into the chips? I worry about that with our guys here.
cats no, they seem to have more sense
my cats are excluded from the machinery area
the dog normally can't get in the basement, but if he does...
cradek: that would be nice, but we have the litter boxes under the basement steps, and thats only about 6-8 feet from the lathe
Our Rose likes things that are crunchy, so he scouts out dried leaves from around the garage door.
they do not digest at all well...
I try to sweep up whenever I quit for the day, at least the ones that are out in the open where critters can walk on them
jtr: no, indeed
our litter boxes are in the basement as well. (well, for the cats anyway.)
with the new layout, I'll be able to sweep all the way around the machine, except for the tailstock end
and that end will be up against a cabined that is a foot and a half taller than the bench, so nothing should escape that direction
do you find the height comfortable ( shoptask on top of std height table ? ) I wanted to make a riser
this isn't std height (I don't think)
I made the bench specifically for the shoptask
about 31" from floor to benchtop
good thinkin, easier on the back
Think there's a recommendation about where mumble on the machine should be in relation to your elbows.
if I could just remember what mumble is
for me, the lathe spindle is about 4" above elbow height
steve_stallings is now known as steves_logging
Just checked - about the same here. That might be in one of the TMBR books.
I'm going to work on correcting my sleep deficit. Good night.
The Motenc100 Estop3 hardware estop input appears to be active high, rather than low (as in the manual)...
Oops...there is my text...
and its not sufficiently debounced either...bounces cause the counter values to change by 10's of thousands...
reset bounces that is...
Going to have to set the jumper to disable that input....
Maybe echo the estop through the computer ? hmm...That way it will be debounced...hopefully...
got a new shower head... WOW, is that thing relaxing... 7 different spray settings.
feel so freak'n relaxed after that damn shower... now I don't want to machine the Ti.
How does one negate an output value ?
doing the -not thing confuses Hal, as its directing an EMC signal to the output, and the -not changes the name...
wb9mjn: if you are trying to invert a signal right at the output port, there should be a -invert parameter associated with each output pin
set it true to invert
Disabled hardware estop, and with the EMC1 pids, everything seems to be working ...
Actually, have to setup the home'g by bouncing off a limit yet...
That will be tomorrow...
Ok...on the invert....will see if I can make the hardware Estop with that tomorrow...
Yep...I am usually up at 5 am....
to be honest, I know very little about m5i20 hardware estop
the invert is for a generic digital output
This is the Motenc-100...
First batch of em, actually...2004...
same story, I know nothink
He might have this fixed,,,I will have to call Abdul on monday...
on the mazak, we used one of the pmdx boards with a charge pump for the estop
The hardware Estop is supposed to set the DAC's to 0, but instead its setting the counters to 0...I had never
thats more than a little strange
been using it consequently...
Just use the EMC Estop...
Well, the EMC position display goes to 0, but comes back when Estop comes off, if there is no switch bouncing..
Yea, its wierd...just turned it off for now...
Wired in another input for the Estop in....
Everything came up,,,including the amp enables....funky, though, all the axis are being disabled
on a limit hit on a single axis...
Would think only the limit hit axis would disable...
Also, wont run when reset after a limit hit...
at the moment, I believe all the motion.axis.N.enable pins change to gether
Even if one tries the right direction...will have to double check that though...might have a +/- limit switched...
Just gave a Joint error....when after turning the machine on after the limit error, and tried to move the limit tripped
axis...So, had to had turn the motor out of limit trip...should not do that...
Should let it move in the untripped direction, even with red leters...
Anyway...tomorrow is another day...
Ok on the all enable/disable ...
wb9mjn: tomorrow when everybody is fresh, you should post your hal files and let us take a look
right now I'm too busy trying to throw out my back
moving a lathe ?
right now I've moved and leveled my metal stock cabinet (sits next to the lathe)
I had trouble with my 150 pounder, just putting it up on the bench top...
and I'm putting the drawers back in
some of those drawers are fscking heavy
Put the head on a chair seat...repositioned, got the tail on the bench...repostioned, put the head on the bench...
yeah, patience is the key
the aluminum drawers are much nicer than the steel ones ;-)
Welp...night...rest your back...you will be amazed how much better things go with pauses between the
The back can recover amazingly fast, if you do not do too much at one time...
the talking here - thats pauses ;-)
nine drawers, moving one at a time with a few mins rest between each one
I was thinking about moving the lathe into final position next, but I might let that go until tomorrow
Oh..."Overide Limits" works now...hi...
That is why it was giving the joint error...
If I hit Overide Limits, then restart the machine, I can move out of the trip, and the Overide Limits turns back to
normal from red...
yeah, override lasts for one move only, then resets itself
jmk: know those light towers on machine tools... a stack of red green blue lights? tell you machine status from a distance?
here's a homebrew replacement, it could tell you when a job was done...
[05:03:41] <tomp> http://linux.softpedia.com/progScreenshots/Push-Puppet-Toy-Screenshot-21118.html
got the lathe in the right position now... just have to level it
i've been modelling anew meter widget after the gtkdial widget... bad idea cuz gtkdial is an input device, and uses mouse events to trigger updates
i want updates when the underlying 'adjustment' object changes due to , some analog input on an i/o card
back to drawing board ( tho the code for the ticks is useful )
everything is moved
time for bed
goodnite, good work!
alex_joni, so ... robot wrist protection ... apart from the obvious one of "buy something expensive" what are the alternatives, seen any workable and buildbale protection devices?
alex_joni, I was thinking of something involving some neo magnets
you know ... the electrical safety that trips when you bang the torch up against something solid
on axis 6
bah, I need a PC with DOS on it I thinl
this crap old software doesnt seem to be able to access the serial ports under windows XP dos-like thing
robin__sz: that's torch protection
and it usually is done after the wrist
the most simple ones are mechanical with 3 contacts
cradek: here's one with round buttons: http://www.toenne-online.de/Mach/toenne-screen.jpg
new psu for the mill pc today :)
* anonimasu is going to write code for the plc/keypad in a bit
alex_joni: are you awake?
Have he amp enables seperated out now, and the homes tied to Xmin, Ymin and Zmax limits...time to redo the ini
for bounce of limit homing...
anonimasu: he went away a while ago
probably here soon
Hmm...might have to go back to the old method....on the homing...just realised the - limit turns off the amp, and
there will be a following error....But that is not what is happening...
Even though "Ignore_limits" is on its emc is halting with an error limit....
you're trying to home on a limit switch?
what version of emc is this?
Got the X and Y working now...
EMC 2....Ubuntu 6.06 ...
They reverse and come of the limit faster than the amp can shut down...
But the Z axis is throwing the following error...
First time I have had a full auto homing on this machine ... YooooHoooo!
following error or limit error?
Limit Error was due to a home switch input signal polarity mistake...
Now, as I figured, I am getting the following error, but only on the big slow clunky Z column axis...
if you use HOME_IGNORE_LIMITS=YES it will not throw an error or disable the amps
Yes,,I did that originally...
Well, I have the limits directly wired to the amps...
obviously you shouldn't do that and home on them too!
Might need to put a cap on the Z limit + signal, with a diode...
Well, its working on the X and Y ...Yea, learning is such a neat thing...
Or maybe set up a real home switch for the Z...
yeah, it's not surprising you get a following error if you turn the amp off!
The cap would keep the amp on for a hundred msec...
sounds like you need more switches or something
The X and Y are working...so the computer is faster than the Amp can fault out...
doesn't that time reduce or eliminate the crash protection?
.1sec is a very long time at full velocity
Yea, but my z axis going upward stops going upward very fast...
ok sounds like you have a handle on it, I'll stop "helping"
It has allot of friction, and unpowered will drop down about .050 inches until the Z brake catches...
thought you might be having an emc problem, but sounds like it's not
Have to hack on it somemore and see if I can figure for sure I know what is going on, and a workaround...
Yea, I thought there was an EMC problem with the limits...but its was a config problem instead...
good to hear, ok, good luck
Z limit switch is out of adjustment...limit of travel was tripping the following error...how did that happen !?
limit of travel?(end of way)?
finally on the walk of making the plc talk to the pc
Making progress...but there is too much hysteresis in the Z limit switch...its reverseing, and when the index
pulse fires, after making half a turn of the screw, the limit is still active, and it trips out...
The X and Y limits have push operators....
can you move the switch or rotate the encoder?
The Z has rotory operators....
Tried both, the problem is the hysteresis is more than one turn of the screw (.2 inch) ...I think...
oh, that's a lot
what do you mean 'trips out'?
are you homing when it moves into or off the switch?
When it reestablishes limits, it reads a limit fault, and turns off the machine...
oh I see
Yes, it moves into the switch, reverses and then finds the index...i believe...
just home when it goes off the switch then
I can see it reverse and slow down...
Want accurate indexed homeing...
right it will back off from the switch and then search for index
[16:22:39] <cradek> http://linuxcnc.org/docs/2.1/html/config/ini_homing/index.html
It might be OK...just that the zero trips the switch...
I think you want the third diagram
Yes, I have reviewed that....
Yep, except the limit off is to the left of the index ....
wb9mjn: I don't understand...
Probably the next diagram down would work, but the index would be just right of the release, and left of the trip..
Will go give that a try...
maybe your final home position is wrong so it's inside the switch
you should have it pull away from the switch on the final homing move
See where the 3.000 index is?
The last one is what I am going to try, the one above, is what is happening, but with the 3.000 index between the
trip and release...
wb9mjn: I think in picture #3 it would ignore the index between the trip/release and go to the next one
Yea, it does...but then when it exits to normal operation, at 0.000 (my home value) the limit is still active...
oh just move HOME_OFFSET so 0 is outside the switch
By going to the bottom diagram, the hysteresis will be taken care of, and the index will be prior to the positive going trip...
HOME_OFFSET = -0.3
I could make home offset +.25 ? But think I ll try diagram 4 first...
HOME_OFFSET should be negative (up) I think
This is the Z axis, max up is 0 the way its setup ...
Let you know what happens...
after homing it will go down 0.3 from the index and call that 0 (HOME)
ok you'll get it :-)
this is a bit hairy to get right
So you can use the limit switch as a home switch?
there is lots of flexibility in homing
[16:32:52] <cradek> http://linuxcnc.org/docs/2.1/html/config/ini_homing/index.html
there's a nice picture here
I have that open - was scanning to see if limit switches were mentioned.
then in HAL you just hook your switch to both the limit and home inputs
then during homing it is ignored as a limit, and when not homing it's honored as a limit switch
Ok, thanks. I see it now.
hm, I wonder if inductive sensors are sensitive enough for homing.
anonimasu: depends just on the repeatability you need I suppose
cradek: really you can ignore that question..
if you use index and you know your switch will always fire between a certain pair of indexes, that's good enough
I have dataheets at work :)
cradek: a company that sells 1µm switches ;)
repetability that is..
Ok...figured it out hysteresis was more like .050, and was doing diagram 4 by accident (ini typo)...
if the switch is sloppy you'd want to put it centered between indexes
All three axis home now...full auto !!
wb9mjn: what emc2 version do you have?
later versions (if using AXIS) have "home all" that you might like
but that's not in the 2.0 release series
cradek: I have a feature request/thingie for axis, if you care :)
centering a sloppy swx between index pulses is important, if it gets near egdges, then home doesnt repeat >sometimes<
anonimasu: sure what?
cradek: a selection for what tool you are using and a offset button..
The LiveCD Ubuntu 6.06 ...
anonimasu: I don't understand
cradek: for setting up tool length offsets without editing the tool table
anonimasu is right...
wb9mjn: ok you won't have "home all" - you will have it with later 2.1 release
Sometimes the limits home switch will trip on one side or the other of the index...
If the trip is too close to the index...
anonimasu: I have to think about how that could be handled. there is a call to make emc reread the tool table, but that's about all we have to work with
These limits switches here will vary by about .002 inch...
cradek: nice :)
Now I need to got get a vacumm that can pull the chips out of the slots, high...still full of brass shavings from
the fixtures I made a couple of weeks ago...
cradek: editing the file
file's might give a bit of a pain I think
anonimasu: yeah it's sometimes trouble to automatically edit a file that's also edited manually sometimes
I just edit the file and hit 'reload tool table' in AXIS
though as they are space separated i's probably not too hard
cradek: I were pondering with one of thoose nice tool length setters..
oh like a switch you poke with the tool?
cradek: Ideally you would have a electronic one.. and push (set tool length) and it'd jog down and set the length for tool _x_
that would be neat
in extension with a toolchanger you could set up all your tools at once..
total overkill though..
you could actually measure them all with probing BUT you would have to put the results in the tool table yourself.
so, which app do you people use for doing PCB's?
yeah, there are fully automatic ones with pnp outputs and manual ones with a lamp
how's the learning curve?
kind of bad
you need to read the tutorial
cradek: either way it would be a useful feature :)
shower time :)
cradek: "the" tutorial?
it comes with it?
I need to go to work and fetch the plc.. and start hacking on something to talk to nml
on the pc side
I think you can find the tutorial on their site - however I bought a license and they sent a booklet tutorial too
(at least, its still morning somewhere)
here it is
morning is that part of the day before I get showered
got the lathe moved
cradek: I've finished doing stuff/being out in the shop for today
cradek: way oil in the hair :)
does anyone of you know where to find a example how to talk to nml?
anonimasu: sure, I know :)
alex_joni: got a .c file?
alex_joni: or is it the usual "read the wiki" ;)
alex_joni: hi, and what's up :D
anonimasu: you can use emcmodule to send commands using python
hm, I dont code python :/
unless there's a serial port library that's nice to use with python
yes there is
there's a library for everything
anonimasu: there are lots of examples for nml
anonimasu: even halui.cc, which is c++
the parent of all these files is xemc.cc
cradek: is python hard to learn?
anonimasu: not the basic things
alex_joni, so, know any tame comau dealers?
anonimasu: it's easy to read
you don't have to be an expert to start using it (just look at me)
they are not around these parts :)
cradek: what I need is a lib that reads a port and throws a nml message based on what kind of stuff it getsd..
or well, a lib for port reading and another for nml..
anonimasu: that's exactly how halui wrks
is that easy or hard?
are you sure you don't want to use halui?
alex_joni, the bot has been off for a couple of years and has forgottenthe contents of its ramdisk .. no problem, I have the boot floppies ... but one of them is hard to read .. I got _nearly_ everything off it .. but two files are troublesome :(
it'd be a good chance to start with it..
unless anyone can think of a better way to try and get data off a floppy other than just mounting it?
dd it and make a copy?
dd if=/dev/fd0 of=fdX.img
if you mount it, be sure it's write protected
there's a switch to ignore errors..
* robin__sz made sure it was write protected
alex_joni: halui seems nice and simple also
Gotta retune pids...probably because of the lack of FF2 ... took the vice of thetable, and now it oscillates a little...
oh, it copied ..
wb9mjn: ff2 is in the latest HEAD
Spindle Speed control this afternnon... thank Alex... will wait for it go get in a general distribution...
whats that trick for mounting stuff via the loop device?
Off to lunch...
I really should make the last three drawers for the bench
its only been 8 years since I built the bench ;-)
mount -t msdos -o loop <file> /mnt/dir/
jmkasunich: now you will spray oil on your scope
I think ff2 will is in version 2.1
cradek: I'm going to have to make a chip guard for the back
[17:32:29] <anonimasu> http://pyserial.sourceforge.net/
anybody have any thoughts on where to mount keyboard and display?
need to keep them clear of chips and crud, but not to far from the machine
to the right
I will have a jogwheel, so the keyboard doesn't have to be exteremely convenient
I was thinking about the wall to the right, is that what you mean?
it's not loading here :/
cradek: I think I'll go with python..
cradek: it's a fair enough chance to try it out
alex_joni: whats not, pyserial or my pic?
jmkasunich: your pic,. think too many people were loading that
now it worked
jmkasunich: on top of that numbered cabinet maybe
yeah, its being served from my dsl, not a speed demon
cradek: that's what I was thinking
where the toolbox is right now?
instead of that greenish cabinet
I've gotten used to having that box
I hope it isnt a mess to learn :D
jmk, is that the "all in one" lathe?
can you get in those drawers or will you have to move the drill press?
(that is my dad's machinists box, only about 40 years old)
lathe + mill?
the one that was a pita to mill in?
the millhead is on the floor right now
cradek: the drawers open all the way
cradek: bad perspective :)
there is more space between the drillpress and machine than appears in the pics
oh, I see
look at the bottom of the pic.. you can see the distance more clearly
Lerneaen_Hydra_: a few pics of the machine before move, and the parts, are here: http://jmkasunich.dyndns.org/cgi-bin/blosxom
jmkasunich: what kind of display?
CRT or TFT/LCD ?
it will be an LCD
probably a 15", they're down to around $100 these days
you can clean the front of a CRT
how about that door behind the machine?
but an LCD is 3" thick instead of 15
that one painted in 2 colours
too far away (more persepective)
jmk, nice cap explosion
a machinist's computer: looks like a tool box, lcd under top (liftys open) kbd slides out from under ( like drawer protector) and has a handle on top
jmkasunich: I see now
jmkasunich: monitor+keyb arm?
thats a possiblilty
[17:40:25] <alex_joni> http://www.sum.co.uk/monitor%20arm.jpg
once the millhead is back on, it might be possible to put the LCD on the machine itself, up high
keyboard is the real challange
jmkasunich: like this: http://www.esis.com.au/LCD-Monitors/Arm_LA-518-1.jpg
jmkasunich: get one of those flexible keyboards, the ones made out of rubber, and put it right on the desk in front of the machine.. you can wash those off
rayh asked for ideas about this recently - wonder what he came up with
ooh video wall :)
alex_joni: that space in front of the machine would be death for any keyboard
[17:42:21] <tomp> http://gstreamer.freedesktop.org/apps/videowhale.html
jmkasunich: one like this: http://www.engravetech.com/Flexible%20Keyboard%20small.jpg
when I'm turning steel I get chips that are blue hot
distance is your best protection ( short of hard covers )
especially vertical distance ;-)
if you get a flexible keyboard then test it first, many of them are made of very very thin plastic
nice: no borders
jmkasunich: pack the keyboard in a drawer under the machine while cutting, use a HAL panel for control
so many cnc controls have vertical kbd... for a reason :) (despite being hell to type on,,, but then you dont write novels there :)
alex_joni: interesting idea
maybe something like this: http://www.networktechinc.com/images/monitor-keyboard-arm.jpg
my keyboard is 18" wide (pretty standard)
the opening under the center of the machine is 13.5"
yeah, an arm like that might work
alaex_joni: thats the wiggly kind I used in Taiwan.. tried several, the drawer is better
another possibility that just jumped into my head....
empty out the top drawer of the cabinet and put the keyboard in there, with the monitor on the wall above
jmkasunich: go on
jmkasunich: there is another possibility for the keyboard
but you need to make a tray for it, and fix the keyboard to the tray
actually a tray is not the best name
a sheet of metal with a hinge
when not used it can be tilted down in front of those drawers, still beeing under the table margin
flip down to use, flip up to get out of the way?
flip down when you don't use it
flip horizontal when you need it
oh, you're still looking at under the bench
sorry: but here you could see where the monitor would go & how the key board would pull out http://www.gerstnerusa.com/
keep in mind that I'm standing when running this machine
do you need keyb when running?
ideal keyboard height (if horizontal) is about lathe spindle height
spindle height is the exact height as the numbered cupboard
yeah - hence the thought about putting it in the top drawer
I pulled it out and stood there pretending to type, not bad really
a 90 degree turn and half a step from looking at lathe chuck to typing
even better might be a tilting shelf like you suggested, attached to the wall above
so when flipped down, its just above the top drawer
that way I wouldn't lose the storage, and I could more easily adjust the angle without my wrists hitting the side of the drawer
flip up against wall when I need to get in the drawers
and tft above that on the wall?
might be a bit far from the machine
that really screams for a HALUI with DRO
surely you can scavange some old BCD numbers
I'm not going to build a display
I'll build a control panel, but the display will be a monitor
so it should be close..
I wonder how small of an LCD I can get before they get expensive again
mount a 10 or 12" display on the machine millhead
btw.. if you don't have the LCD yet.. saw some nice cheap touchscreen ones on ebay
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2006-12-17.txt

yours is a complete PC
unfortunately I want the PC part in the box with the rest of the controls
although I could run a remote GUI on the item you found, and let the controller PC focus on realtime
ok, just stumbled upon it.. it's a P3 with parport
sounds great for emc :D
another thought based on remote GUI... its literally three steps from the machine to the desk where I'm sitting right now
I could run a remote GUI here, and do the "at machine" stuff with halui and display only
still can get docs http://www.datalux.com/lcd_overview.asp
i've used these, got a refurb from them near 150$ for 19" http://www.magictouch.com/addon.html
hmm.. parallel.. nm
heh, I bet its actually 25 pin serial
its a dumb terminal with touchscreen
lots of good ideas here
I'm leaning towards halui and physical buttons (plus the jogwheel) for frequently used things that need to be located very close to the machine
with an LCD mounted on the machine as the monitor
and maybe no keyboard at all at the machine itself
then run a remote GUI on my main PC 3 steps away, for loading programs and such
if I can find a suitable touchscreen, that could give me even more at-machine controls, and still not need a keyboard
I bought my 50 pin header breakout from Advantech...expensive stuff...
Although the header was a reasonable deal....
Been on their email list since...
Are you guys interested in that computer ? I need to upgrade the stepper milling machine here, if you are not interetested ?
which computer? the one on ebay (PC with flatscreen)?
wb9mjn: not sure it even works
if you want it, go for it
I won't be bidding, I have other stuff on my plate right now
The touch panel PC Advantech PPC-153M ...
That is a panel pc, just needs a hard drive...
Need to see if it has USB ports, for mouse and keyboard, to set it up...
It has built in audio...but, the mother board might not be Linux compatible...
Have to look some more to be sure...
can take one small pci add-on card...
wb9mjn: 2 usb
Has a LAN port...
Or at least a LAN driver in the support page for it...
too bad they do not have the manual on their website...
[18:59:21] <alex_joni> http://ebay.sunnkinglister.com/jpappa/ik111-6.jpg
would be a great emc2 machine at 850 MHz with 256 RAM..
Yep,,,that is what it has in it...
You can see it in the boot screen...
Could put that on my Proxon-MF50...
Are you going to bid on it Alex ?
I'm in the EU.. shipping would be a problem
might take a rist on it then...
Rather than filling another metal box....
wouldn't pay much more than 150$ though..
something like that...
150 probably wont take it, they are up to 103 already...
more than 1 day left..
so probably more like 2-300$ on this
cradek: wrt eagle, if I have a component that I know the physical dimensions of, but can't find in the part database, is it easy to insert it later on into the layout?
without breaking something
eagle: help menu : quick introduction : creating a library device
ah, thanks. something else I've noticed is that I'm unable to get wires to attach to component leads easily
sometimes they lie on top of each other, but no contact
move the components slightly
it works on most schematic editors I tried
and new libs (not in the std free distro) are available at cadsoft website
Lerneaen_Hydra_: you're using nets, not wires, to connect pins right?
Lerneaen_Hydra_: I told you: you have to read the tutorial
maybe use snap to grid (after placing component on the grid )
pspice habits kicking in
cradek: I know, i know, I did look at it a bit :p
Lerneaen_Hydra_: I only know that because I tried to use it without reading the tutorial too :-)
the demo xmpl looks like 8 axis hydraulic hexapod control
does rtfx exist? a complimentry acronym for run the farkn examples :)
Hello John? ....Have you done anything to Hal'ize "SPINDLE_ON+INDEX" ?
wb9mjn: spindle on index?
Yes....it takes a fourth DAC output and uses it as a speed control for the spindle...
Or any DAC output...
I don't understand what that has to do with index
you simply connect motion.spindle-speed-out to the DAC you want
With EMC 1, I had "SPINDLE_ON_INDEX" = 3 ....the 4th Motenc-100 DAC output would then
or iocontrol.0.spindle-speed-out if you still have emc 2.0.x
put out a voltage from -10 to +10 for the speed...
wb9mjn: that's how it works in HAL now
wb9mjn: you still have emc 2.0.x right?
Ok....I think I have 2.0x ...
I have the LiveCD Ubuntu 6.06 installed on the harddrive...
alex_joni: do you have experience with duel booting
skunkworks: in a minute.. let me talk wb9mjn through this first
march thirty paces then turn and fire !
wb9mjn: ok, so probably 2.0.5 if you have the latest updates
I did do the updates...
wb9mjn: there is a program called iocontrol which controlls I/O (how odd isn't it :)
now, that program has some hal pins
one of those hal pins is iocontrol.0.spindle-speed-out
it will hold a float value of the spindle set
so for S500 in the program, iocontrol.0.spindle-speed-out will be 500.0
you just need to scale that to match your voltage/rpm,connect it to an empty DAC and you should be set
There was scaling in the spindle_on_index setup too...
you can scale and offset at the dac if you need to
wb9mjn: if you open the nist-lathe config you can see the scaling and connections there
Ok...let me take a look...did not look at that one when trying to figure it out on my own...
it's not in v2_0 :)
but I can still talk you through this.. if you want :D
look at this: http://cvs.linuxcnc.org/cgi-bin/cvsweb.cgi/emc2/configs/nist-lathe/nist-lathe.hal?rev=1.10;content-type=text%2Fplain;only_with_tag=v2_1_branch
alex_joni: I think the motenc dac has scale/offset and that's the simplest way to scale it
ok, that's true
Sure...thought I saw that nist-lathe somewhere...guess not...
missed that wb9mjn wants a motenc to drive this
no need for a scale block then
yeah he has real dacs, unlike me :-)
The scaling was done with two other parameters in the .ini ...
i seem to need to 'tune' dacs... like set the signal to 0 then measure the pin, inserts that offset: then set max value and set scale, recheck
wb9mjn: do you remember what the params were called?
The DAC hardware is all tuned up....0 v in , 0 volts offset....10 volts in , 10 volts out...
tomp: that is correct, you would determine the offset (to make it output 0 when commanding 0), and scale to make it output10 when commanding 10
The spindle drive uses 0 to + 10 V for speed signal...
Does not reverse..
wb9mjn: what are the ini variables you used before?
On the EMC 1, the variables were max_volts_per_rpm = .005 and min_volts_per_rpm = .000001 ...
The first parameter scales from spindle speed to the cw 0-to-10 volts output...
yeah, and the second for reverse.. it's a bit borken
because there's no way to offset
So, 2000 RPM puts out 10 volts ...
And put in a reverse RPM value, and it stays near 0....to avoid driving the spindle with too large a negative voltage...
Spindle Drive electronics and motor are unidirectional...
[20:14:34] <alex_joni> http://pastebin.ca/282684
that's the basic of it
but I'll add the testing for negative next
tell me if you get/don't get that
The DAC and Isolator will put out negative , if fed negative...
so, I put this text into the motenc_io.hal ?
hang on, I'm working on a version which does only positive output
but did you _understand_ the first one?
Yea, kinda....what I do not understand is where to come up with the variable names....
But, that is in the text, so no problem...
the variables are in the User Manual
and they magicly appear by using "halcmd show"
or by selecting halmeter or halshow from the AXIS menu (or the tkemc menu)
[20:21:43] <Lerneaen_Hydra_> http://www.youtube.com/watch?v=HKv8_iZRmYk&mode=related&search=
Yea,,,I was looking at the hal show script, and did not see the speed variable...just up / down / fwd / rev ..
Lerneaen: so why was it banned? :)
wb9mjn: this might be it
[20:24:42] <alex_joni> http://pastebin.ca/282698
(where a cheap hud?)
computer signaling device (upscale push toy) www.nabaztag.com a bunny animatron can signal machine status
Lerneaen_Hydra_: this is nicer : http://www.youtube.com/watch?v=6M7o66Ojsh0
almost the same one, but a bit funnier
[20:37:14] <alex_joni> http://www.youtube.com/watch?v=lt4PhS6RqpI
ok, i tried the first one and it errored out "spindle_speed_cmd" not found ...
I never wrote spindle_speed_cmd
I wrote spindle-speed-cmd
Ok..I see the problem...
Off to try it again....yea, well haven't done text programing in some years...
OK...just typed it wrong on here....
Was s"spindle-speed-cmd" in motenc-io.hal...
can you check the rest?
maybe copy the motenc-io.hal and put it on pastebin.ca ?
The linkps /sp threw me thought that was a typo....let me get it all in there as you typed it, and double check...
sp is signal to pin
ps is pin to signal
Ok,....first one is working !!!
spindle is controlled in speed....
I ll go enter the second one...and we will see how that works...
anyone know of some g-code for db-9 etc cutouts?
[21:01:22] <alex_joni> http://www.resursadefun.ro/gi37_Verizon.htm
ChrisSmol: I found my DB25 drawing - let me export it to gcode
[21:04:00] <skunkworks> https://help.ubuntu.com/community/WindowsDualBoot
ChrisSmol: it was written for 1/16th end mill - is that ok?
yeah, i can modify it, i was going to use a 1/8 end mill so as to use it to put in the two holes, or are you doing that with the 1/16 also?
tells me I need to make atleast 2 partitions - root and swap. but what do I maket them? primary or extended
looks like those are drill cycles in this drawing
looks like I used a .120 drill
maybe that's #4 screw?
ok. i was going to do it all with one tool
should be a #4
I can do an offset to 1/8th for you
i figure .125 is close enough to .120 ;-)
that would be cool
how thick is the material?
skunkworks: primary works
but you can only make 4 primary's
skunkworks: if you plan on having more than 2 doze partitions it's hard
just xp and ubuntu
No Joy....limit1.0.out not found....
xp is installed
50gb of unallocated space
is that first line right ? loadrt blocks limit1=1 ?
hmm. plastic, some is 1/16 and some is 1/8 (roughly) thick
wb9mjn: I might be wrong.. been a while
ok I'll use .130 deep, you can change it
everything else says limit1.0 ?
wb9mjn: what's the exact error?
limit1.0.out not found
it should be "loadrt blocks limit1=1"
then limit1.0.in and limit1.0.out
ChrisSmol: can you measure center-to-center of the holes on a DB9 for me, I'll generate DB9 and DB25 both
Ok...yep....that is what I believe put in there...
going to double check....
the db-9 holes are .984 apart
maybe ( very very close)
ok let me draw the DB9, one minute
where do you assume the home is?
I was just trying to figure out how to explain that
[21:23:30] <cradek> http://timeguy.com/cradek-files/emc/db9.png
look at this picture
see the origin there in the arrows
the white is the outline you get, the green is the tool path
looks like the intersection of the bottom of the cutout and the extreme left edge
I probably should have put it at one of the holes
OK .... its all working !!! typoes...
i'll move it in the code, i use the center of the cutout as the origin
Negative stuff just goes to 0 ....
i want to study the g-code to understand it first
if it's a huge pain I can regenerate it
thanks allot Alex .....
wb9mjn: seems my HAL-foo is still good :)
nah, i need to learn g-code properly anyway
never got a chance to test any of that :)
and everybody who has done a world of work to get EMC2 into such a much more straight forward thing!
PID tuning, and I am back operational...
Not bad for a friday night, saturday, and part of sunday...
EMC 1 would have taken weeks....
wb9mjn: glad you feel that way
(did take weeks) ...
most of it was rewiring for the more complete signal set, and to use the Motenc-100 I/O rather than parallel ports...
jmkasunich: you still around?
holy sh!t - I have a duel boot machine ;)
only took 2 tries. the first try borked my xp setup
now you're only half as bad off as you were before...
I made 3 partions root, swap and home
assuming that it all allocated correctly ;)
jmkasunich: my monitor is on a post that rises from the back corner of the table, and the keyboard is from an old compac lunchbox that sits in a frame hanging off the monitor
don't let Windows and Linux duel to the death now...hi..
jmkasunich: see http://members.shaw.ca/ve7it/p1010065.jpg
LawrenceG: heh I have some of those little keyboards too
so question #2 - how would I go about getting the wireless card working?
cradek: hi... I painted mine to match the shoptask
I guess mine look different, forget it
skunkworks: what chipset?
skunkworks: the basic answer is google or ubuntu wiki
or ubuntu help forums
skunkworks: some just work nicely (prism)
ok. it is a buffalo wli-cb-g54s
will do some searching
LawrenceG: what are the switches where the old handwheel was? homing? limits?
tomp: limits... there is kind of a cam I made that trips them on ench end of rotation
is it easy to type on with the tailstock installed?
jmkasunich: the whole thing swivels... it is tight with the tailstock, but it swivels right out of the way when puttutting the tailstock on and off
other than oily fingers, I dont get much junk in the keyboard
what's in the spindle in that pic?
just some kind of an extender?
cradek, i should be able to just add an offset to all of the x and y positions, in your g-code, right?
the post is the brown thing under the keyboard and it fits in a hole drilled in the corner of the table
yes you could run that code inside a coordinate system like G55, or you could use G92
1 1/4 pipe I think
ok, thanks. still new at this.
or you could subtract the right number from each X and Y coordinate :-)
LawrenceG: understood about the pipe
you're jumping right into the hard part then
I'm asking about the mill spindle tooling
jmkasunich: yes... an extention with a 1/4" collet with a pcb cutting bit in a 1/4 to 1/8 collet adapter
ok, that's for fine work? (seems rather floppy for any heavy cuts)
jmkasunich: the black square is a piece of plexy I milled flat and use to tape pcb on for milling circuit boards
do you have ballscrews?
(I can't imagine trying to do pcb work with the stock screws)
jmkasunich: I built a higher table jig for pcb that I use now and just use the drill chuck... very light loads.. I do have ball screws, but to tell you the truth, I think they were a waste of mone
well, my acme screws have about 0.010 backlash
way too much for PCB work I think
my ball screws are not much better... there is too much spring between the nut and the x axis... needs a better connection
oh yeah, that
I've looked at that several times - it needs a better design
if the chip guard was removed, the screw could directly mate to the x carriage
yeah, but it would die quickly from chips
I think it could be stiffened up while retaining the chipguard
yes... a stiffer nut mount would be a great improvement
I would like a better z axis as well
I saw your drawing.... got me thinking now
one really needs a high speed spindle for pcb work....
and maybe an encoder & motor for turning the cross slide ( it's built to be turned )
tomp: that would be interesting
there's times when a troyke table is handier than a cnc approach
I plan on pinning my cross-slide - I don't want it turning
then you might be able to gain some swing by lowering it, or put the screw centered under it
when working as a lathe, I want it to be exactly square, not just "kinda" square, which is the best you'll get if you have it motorized
it swings 8" over the table, thats enough
I'm going to be doing enough mechanical mods, lowering the table is a bitt too much
kind of square.. makes consistent crap
i have a one problem
i like install emc on slack
but, it's really not worth the effort..
You need rtlinux first of all...
then you need all the build dependencies for emc..
my kernel is 2.4.26
how install rtlinux?
it's a kernel patch.
You need to download the patch and apply it to your kernel..
[22:56:59] <anonimasu> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?RealTime
[22:57:07] <anonimasu> http://www.faqs.org/docs/Linux-HOWTO/RTLinux-HOWTO.html
but as I said, it's not worth the work when you can grab the livecd/dualboot ubuntu..
anonimasu: rtlinux isn't advised
I'd use RTAI
you can get it at www.rtai.org
alex_joni: isnt that the patches you are supposed to use?
anonimasu: nope, RTLinux is the dark side RT :D
they mostly do the commercial version
not sure anyone has run emc2 on rtlinux in the last 1-2 years
* anonimasu nods
it probably won't work at all in the beginning
