Another lathe config
Not that link.
[00:13:08] <andypugh> http://www.bodgesoc.org/lathe/lathe.html
an oft-repeated expression here...
That does 95% of my lathe work.
ooooh this is real cool. I'm looking...
(Though in the actual screenshot it has a different G-code file loaded)
I am thinking that I might change the way it works, though. I keep hitting "run" with the wrong file loaded (ie not the special one) or boring when I mean to part etc. A better way would be to have G-code routines called by (for example) a "boring" button that reads the values and does the operation regardless of loaded file (this is pretty much how the tool-select buttons work)
I am all jazzed about that... I it is very much like what I was wishing I had.
You wrote all this?
Feel free to re-use any bits that suit your needs
That tach, for instance, does it run in a slow thread, and does it stay fairly stable?
It runs in the servo thread, but has a lowpass filter to steady it. As the machine runs CSS in that config it is pretty pointless anyway. I might make it digital to make some more space
can it be used with a stepper config? I have a spindle endoder (quad) and index already working...
That is a stepper config
Though it uses a Mesa card
andypugh: in comp programming... I see sometimes variables are defined before ;; and sometimes after... does it have to do with what gets kept from thread run to thread run?
could it be thought as global and local?>
I can do threading right now (g76) but I have to be careful not to over-rev the spindle to avoid aliasing thenrpm / position. That tach would be helpful
skunkworks: I think it is to do with variable scope, yes. The ones before the ;; are "storage" variables
davidf: When you get to the point of running 2 p-port cards the Mesa 7i43 starts to look like $75 well spent. It gives you 48 channels of IO, with hardware stepgens, encoder counters that can count to MHz, PWM to 100kHz etc. It plugs into the parallel port itself.
btw I haven't been using the post-gui custom hal files etc. Can you do most anything you need to add in those files, w/o messing with your mail hal and ini?
so - If the data is stored in a pin - then I could use that data from run to run.
Just spent $35.00 on a 2nd card, and $30 on a second BOB.
* skunkworks should just try it ;)
Yes, that is what they are for, so you can keep the stepconf wizard config and tweak things there, and then keep the custom stuff safe in the custom and postgui. I got bored of all the unlinkp lines neede though, and I just work directly in HAL now, (I don't even pull values from the INI, they are explcit in the HAL)
skunkworks: Yes, pins count as static storage too. But the pre-;; variables are useful for things you don't want to make a pin for.
andypugh: thanks - coming together :)
OK, 0130 here. Have fun.
so i've been on holidays for a bit over a week what have i missed?
oh got some posts up about our contact probe
[00:42:50] <Valen> http://www.cnczone.com/forums/showthread.php?t=109146
7:30 pm yesterday here. :)
How is tomorrow morning looking?
fine and sunny
100 F super humid here
you can keep that
just awful, like a sauna been that way for weeks
yeah thats no fun
tis winter here
thank God for AC
Grass in back yard is 18 inches, been too hot and wet to mow it
that's right opposite seasons, forgot that.
havent mowed in months
about an inch and a bit lol
I got my spindle speed display working :) and had my first involvment with hal!
it was a really simple problem too
Gangsta: hooking the right pin to the right ping? ;)
davidf: sounds like here. where you in chicago?
for some reason stepconf decided that i didnt have a spindle encoder so connected the speed display to commanded rpm instead of actual
Gangsta: how is it working?
spindle is accurate to within 25 rpm of commanded, verified by my scope
not bad for a pwm -> DAC (0-10v) with only 4 components
was just looking at Valen 's post re that probe. Interesting, looks good
not too bad for the first attempt
im very new to this, is there something in hal that will smooth my speed display - its a little bit jumpy at the moment, like a filter. im reading the manual but its lots to takee in
I do believe there are filter widgets
yes there is. let me check. it's something like position_interpolated I think
what pins did you hook up? the encoder module has a interpolated velocity pin
its a filter module as i recall
so is that velocity-interpolated?
I don't think thats what you want
probably - es
you want a low pass filter
will that be easier than a filter?
to make the display not flicker
I would try the interpolated pin first... see how that works. (easy to try)
thats true. and ive found a section called low pass too :)
you are going to be a hal master soon :)
actually sorry i'm not sure if low pass is what you want
you want a time average
its not as bad as it looks tbh
i wish i had looked sooner, mabey it wouldnt have taken so long to get going
I have worked on tuning my PID loop on my Bridgeport Interact. I finally got to the point that with slow or rapid moves, my following error is always udner 0.002", and usually under 0.001". Is that "good enough"?
if your making telescope mirrors then no, if your making cupboards then yes
+1 for Valen
I believe this is an Agilent scope. http://qurl.org/Q31
Is it worth the price? I have no idea on the age. 100MHz is a good range, no?
if your measuring AVR serial streams yes, if your debugging USB3 data streams then no
that scope seems like overkill in aa number of respects
if you can get a storage scope it'd probably be more usefull
here is a better pic of the front: http://mark.rehorst.com/AN_USM_338/front.JPG
you can have it trigger and it'll keep the trace on the screen
wow, tiny screen :/
that was my other concern
it really depends on what you want to do with it
if your in the field, then it might be a good one, though the new "pocket" ones might be better
see the gold circuitry? http://mark.rehorst.com/AN_USM_338/bottom.JPG
anyways... it is from the 70's
its not that expensive to get stuff plated
don't know how 'burnt' the screen is
scopes don't seem to burn really
I've got valve powered ones that still seem to work ok
this one is less expensive. http://qurl.org/R31
tek is a good brand
less features, though.
it really does depend on what you want to do
I aim to use it for trouble shooting and dissecting cnc components ;)

anyone want to lend me $600? :D
that'll do it for ya
half my paycheque!
I got a 750mhz 4 chan tek
not a storage scope though
if I made it into a business... then it would be worth it.
750MHz? these are only 60MHz
I think its 750
might be 350
that is awsomely high. you could scope TV transmitters!
channel 21-36 is bellow 608MHz
Valen: I see the interest in the portable scopes. they look great. http://toronto.en.craigslist.ca/tor/ele/1818401412.html

Will emc2's realtime run for programming purpose run unter vmware or virtualbox ?
Shopfloor is too noisy for me to concentrate :(
I run emc2 under vmware server all the time
but you can also configure emc2 to run in simulation mode (you don't get access to drivers - but using VM you don't anyways)
that way you can run on any distro with the stock kernel
no I'd like to be able to run "realtime" even if it's just inside a virtual machine
did you try virtualbox ?
or just vmware server ?
never tried virtualbox
to bad, but if it runs under vmware, that I'll give it a try
maybe someone else has
I vaguely recall jthornton mentioning a couple days ago in #emc-devel
check the logs
how's life in Timisoara going ?
2010-08-02 13:51:29 <JT-Work> my last install on the zotac was stock 10.04 + your script... all working fine and playing nice with everything else including virtualbox ose

Fox_Muldr is now known as Fox_M|afk
Haha, no rest for the wicked :)
You were on vacations ?
took a couple days off
well, enjoy your pile then. I'll probably get back once I have problems with emc in virtualbox :(
I played with bubbles :D
birdman3131|zzzz is now known as Birdman3131
what use is "realtime" if its inside the vm?
Valen: it has some use
it ensures you run the exact same environment as the real machine
yeah but you can't actually do anything with it though?
no, you can only run sim configs
and test the kernel, etc
but the sim doesn't use realtime anyway?
I can see the kernel testing being handy inside a VM
sim uses RT if emc2 isn't compiled without RT

the second is an error
[10:25:41] <alex_joni> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?UPDATING#emc_nml_changes
any ideas on the error ? I am using axis_mm.ini from the sim examples
sorry, moment have a read your link
Ah Alex, your a gem!
It starts, complains about a realtime delay, which is ok inside a vm, and then shows axis in all its glory :)
Who do I notify that the axis_mm.ini sim example needs to have this line removed ?
it's more likely your axis_mm was from 2.3.x
Hey Alex, I updated to v2.4 right after installing
and then started emc2
but the original version of the cd image contained either 2.2 or 2.3
dunno, but the emc.nml reference was removed in 2009.05.04 from axis_mm.ini
I honestly don't know
ah, I bet I know what happened :)
? Enlighten me please :)
we moved sample config location from /etc/emc2/sample-configs to /usr/share/doc/emc2/sample-configs/
but stuff in /etc/emc2 doesn't get removed when updating the package (debian policy)
so it's likely that you picked the /etc/emc2/sample-config (which was 2.3)
or was it 2.2.x ..
you can check if the files are there
so I should copy from /usr/share/doc/emc2/sample-configs/
the config picker should do that
/etc/emc2/sample-configs does not exist
/usr/share/doc/emc2/sample-configs/ does exist
check sim/axis_mm.ini for emc.nml
yep, I already commented it out
runs, now. (Me is happy :) )
How do I get a screenshot (png) into a wiki page, I have to upload it first
[11:30:44] <maximilian_h> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EMC2RunningInsideVirtualbox
maximilian_h: so you say that /usr/share/doc/emc2/sample-configs/sim/axis_mm.ini contains emc.nml ?
is without emc.nml, but ~/emc2/configs/sim/axis_mm.ini did
ups copy paste problems
I meant /usr/share/doc/emc2/examples/sample-configs/sim/axis_mm.ini is without emc.nml, but ~/emc2/configs/sim/axis_mm.ini did contain the line
honestly, it might be that I tried starting it just after installing, but before upgrading to 2.4

what does this dmesg mean http://paste.org/pastebin/view/21154
@Alex: Is there a way to set the absolute feed rate through the hal layer, not just a factor to it through adaptive_feed. I want to have a fixed feed rate depending on the tool in use
@piasdom: Your realtime setup is somehow not good
I don't know your background: Might me either smi problems, graphics card, bad hw for realtime
new graphic card
steppers or servo
which driver are you using
must be that .... can't get both to work at the same time
graphics driver I mean
can't get vesa to work at all
does your monitor support one of the vesa resolutions ?
have you tried the latency test ?
but that just be "ME" that is not corect :)
will try now
have you tried with xforcevesa on the grub loader ?
never heard of it
xforcevesa forces the graphics card to use the vesa driver
have you tried to use the open source radeon driver ?
when i ran latency before it was about 39000 and i set base 45000. worked but picture was worng
yes i have(open) no good
please try the vesa graphics driver then.
i'll look for xforcevesa
I have to go, the dog is waiting for its midday walk
maximilian_h: you too
piasdom: what maximilian_h said
piasdom: try running the latency test from a terminal
alex_joni: looking to all xforce
(the RTAI latency test -> found in /usr/realtime-*/testsuite/latency/kern iirc)
at 31000 now bu thru icon
then try loading some opengl apps, and see if you get overruns all the time, or only at startup
if you don't get overruns, or only at startup then you *might* be fine
what's the command to run latency ?
it is usually at startup only
i tried this ....
and got seg
and now this when i ./run latency ..... http://paste.org/pastebin/view/21154
finally ..... http://paste.org/pastebin/view/21154
cd to the folder, then sudo ./run
got it running with this cd /usr/realtime*/testsuite/kern/latency; ./run
last paste.org is the results
I doubt that
[12:43:11] <piasdom> http://paste.org/pastebin/view/21157
piasdom: looks good so far
let it run a couple minutes/hours
and really stress the system as much as you can
if you see that the last column is 0, then you're golden ;)
alex_joni: Thanks ok
alex_joni: it'd be handy to see latency errors in EMC more than just at startup
Valen: yeah, but also tricky
if your system has overflows, then you get about 1000 messages/second
Valen: so.. how often would you like the message?
Fox_Muldr is now known as Fox_M|afk
every time? 1000/sec, once / second? once every 10 seconds?
I'm sure it gets annoying really fast either way
a reliable sytem shouldn't have _any_ of these errors
I think there is a count of them, and you can view it with halmeter/halscope
yes, but finding out if something is wrong with your system after you start adding loads of stuff to hal etc
alex_joni is right that you don't really want to have a bunch of popups.
one popup means you have something wrong with your system
not sure I understand. you do get the error message the first time, don't you?
normal log stuff should be sufficent, popup once every N minutes if there is a problem
alex_joni: I get that message every time I start axis
then your setup is broken ;)
then you've got a problem
starting openGL windows causes a latency spike
then you've got a problem
no, I just don't start opengl windows while i'm milling
I'm not sure your assumption that it's OK when the windows are already up is correct
well with latency test running for 48 hours the max latency is ~4500 or so
with glxgears running
exiting and restarting glxgears causes a 30K spike
I haven't seen that particular behavior before
maybe you could fix it by switching to the vesa video driver
I'd rather keep the GL acceleration
chose your poison
there is no poision as far as I can tell
everything works fine, there is a spike when you start openGL
this is with SMP kernel and intel drivers
I had the same behaviour with NVIDIA binary and SMP
does 10.04 use Grub2?
and is EMC with 10.04 still going to use Gnome?
I havent seen a count of latency errors in halscope anywhere
would be handy
is there a way to see "what" is Broken on my sys
synaptic package manager
broken packages ?
thought ya'll meant hardware
I just got here...
elmo40: yes, yes.
trying to fix realtime error
latency test looks ok for now
just don't like that message :)
in the latency test, do i have to look at "all" the overruns or just the last results ?
when you're machining, do you want "all" the g-code to execute properly, or just the last few segments?
mozmck using gnome only because ubuntu comes with it?
ok i get the point
many people have asked why not a lightweight manager such as *box
elmo40: yet none of them have made a cd
you know people... they want the simple way out ;)
how do i check the buffer to see if one went by ?
piasdom: motion.servo.last-period, motion.servo.overruns
cradek: what do i do with that ?
alex_joni: very cool
Fox_M|afk is now known as Fox_Muldr
maybe I will make a lightweight version of the next EMC. Are there 64-bit RTAI kernels?
how much does it weigh now?
depends on if it's on my keychain drive or a cd.
I don't know which one is lighter...
when it is installed on the hd - that weighs quite a bit more.
mine all seem to be quite heavy
one weighs 6k lbs
heh - I think ours is 15ton
that's heavy for sure
Been working on my Bridgeport iNteract last night to improve servo tuning. Went from 0.004-.005" following error to usually under 0.001", almost always under 0.002 even during rapids. Is there some kind of a guideline on how much following error is acceptable.
I've heard 10-20 counts on your encoder
JT-Work: works out to about 0.0005". So I am close. I would leave it as is right now
Do you guys use HeeksCNC? What CAM solutions do you use? I am getting a 4th axis (fixing up an old CNC Troyke rotary table) and would like to get some 4D CAM software

I will talk to them
what do i do with this --> motion.servo.last-period, motion.servo.overruns
can't find anything helpful online
I guess you scream in horror if it ever shows a very big value
awallin: hhahahha thanks
i'll try to scream quietly
killing me softly with overruns - killing me softly... with overruns..
i want to stay away from that command

you can scale the main file
in the example folder
it is protected
copy it to NC-code
open with the editor and scale it down
to fit into the trevel limits
sorry for my bad english im german
na your english is good
ok i will try
what RPM speed do you think ishould try on my dremel
ive only ever milled foam
less then 4inch
the numpad will increase it to 120%
im going to go to the hardware store to get some supplies, what wood sized/thicknesses would you recommend i get for this
if you see it working good
stop the file and double the feedrate
take the chepest
if you got a Modell maker intown ask for Silikone stuff like UREOL
then you can mill with 1200mm/min
at 3mm with and 5mm depth with your chees mill

"wherever I lay my lathe is my home" sung to wherever I lay my hat :)
Well, Its been a long time since my last visite to a "chat" room...
I have built a 4 axis hot wire foam cutter, and waiting for the control electronics from ebay
this is an "irc channel"
me points to the C in irc :)
Im looking at EMC as the control software... (what does IRC stand for)
internet relay chat
internet relay chat
EMC s great and very versatile
By the way, Name here is Matthew. :) can I ask what the basic steps are
to gettinf from a cad drawing to EMC
Guest187: well, there are 2 ways. 1 program the g-code by hand
or 2. get a program to convert say a .dxf file to g-code
Im aware of the need for G-code, but am doing aerofoil tapered wings, hence probably rather harder to do straight coding
yea, thats just silly to do by hand...
i am searching for a free program to convert drawing to g-code myself, so i can help you there...
Yup, I've found a few links for DXF-G-Code software in the knowledge base
*can't help you there...
when doing the cad drawings, might I need to extrapolate the cutting line (hot wire) out from the foam to the X-Y axis, how might this be done
the basic problem is that a cad drawing is flat, so there's not enough information in it to actually make a part
well sometimes there is - for instance a waterjet cutting stuff out of a sheet
some programs START with a cad drawing and then let you add the rest of the information some other way
I don't know what does this well for wire cutting
depending what parts I need to make, I think writing gcode by hand is sometimes the easiest way
[19:36:00] <cradek> http://timeguy.com/cradek/01280719622
for this project I wrote a simple python program that generated the gcode
cradek, awesome set, what are the domensions of raw material
I write perl scripts that generate g codes
ichudov_: the dominoes are .625 x 1.25
what about the raw material pece
it was ~ 2.5" wide piece of scrap .25 plate
I would like to make the same thing, that's why I am asking
I love it
they are fun to play
they feel nice
I like the dominoes... ;) I can get aerofoil plots (X-Y co-ordinates) online - so it might be an idea to look into generating the g-code
So I would like to know the raw material and the python if it is possible
yes if you have coordinates, maybe you can generate the gcode yourself.
I was just lazy
Anyway, nice job
ichudov_: I meant that to Guest
for a tapered cone as an example with the pointy end cut off, i.e. where the foam ends, I would have the imaginary "point" fixed at the center point of the foam X-Y on say the right hand side
and then simply draw a circle in the air big enough to create the mouth of the cone on the left
that requires knowledge of the material thickness, among other things
Ever feel you have entered a conversation at a confusing point?
XY/UV hot wire cutting is the subject, along with CAM for such a machine
I like the german one made from string, the creator of which I think we see on here occasionally?
say the foam block is 1/3 the length of the cutting table, I would then need to make the LHS Circle say twice as big to allow for the cone mouth on the foam to be the correct size....
It depends where the faces of the block are relative to the XY and UV planes
Ive seen the german one, no. I finished building mine last week - minus electronics (ebay) its two independant x-y axis built from 3mm steel sq box
However, I can conceive of a kinematics module that, given the distance from the faces to the axes, and the distance between the axes, could virtually move the XY and UV planes to the surface of the block.
that may be more difficult than you think
or possibly easier than I think
It ought to just be trigonometry, and stuff that has already been solved by raytracing types.
The wire is at least straight.
that may be true in theory, though I'm not sure it is
Is Kinematics a software package?
kinematics is how you translate between the machine's actuators and the cartesian coordinate system that G-code uses
No, it is the part of EMC2 that converts coordinates to actuator positions.
For many machines it is a 1:1 mapping.
That string-based hotwire cutter uses non-trivial kinematics to convert XY UV to lengths of string.
I suppose 1:1 mapping relates to the exact position of the drill / router bit tip
no, to the way that the joints/actuators of the machine move
The problem is that non-standard kinematics involves writing C code.
a knee mill like a Bridgeport has a 1:1 mapping - it has an X, Y, and Z actuator (the table, saddle, and quill respectively)
Ah, ive done that before for robots at uni, pain in the rear
a SCARA robot, which is an arm on a pivoting base, has to be controlled in polar coordinates, but the input G-code is still cartesian
There are a couple of pre-built kinematics modules for robots, so you just need to put in the lengths and offsets.
But for something that automatically projects the cartesian coordinates off of the faces of the foam onto the physical axes (which I think is the conceptually easier way to look at it) you would need to write a custom module.
What I am beginng to see is, I need to do some more reading to get up to speed on G-code etc. so for the mean time Ill get bact to the EMC knowledgebase, and check back here later in the week
Yes, "automatically projects " thats what Im thinkig off .....
It's do-able, I think. And easier than the last time I persuaded somebody that kinematics was the answer.
One problem, though. I am not entirely sure that G-code can handle simultaneous arcs in XY and UV
arcs can only be created in xyz planes. I would think xy and uv moves would be made up of short line segments.
Adding L, M, N words to the G2 and G3 words would have an obvious difficulty.
* xy xz and yz planes
well it's blue
that doesn't seem right...

I am trying to work out if it is worth more or less than what it is masquerading as.
i kind of bought a huge vertical cnc mill
sinumerik 810 control, i tried to get the thing running on the site to test servos etc but i couldn't figure it out
kind of bought?? .... ;-)
moving a 4000kg machine turns out to be a little harder than i initially thought
well, moving it is simple, geting it up on the vehicle on the other hand
That is a good size mill.. Big forklift time..
with the right wallet i suppose it's simple enough
Yes .. money does help.. What do you to move it with?
do you have ...
i can borrow a tractor with suitable trailer, the site i intend to place it on has an overhead crane so getting it off is simple
Some people have used rollback wreckers to load mills, but that might be beyond their limits. If there is a rigger nearby you might be able to get them to load it for not much $.
but i suppose i'll just have to pay someone with a truck with a crane..
i have a feeling that moving the machine will end up costing more than the machine itself
I hired a rigger a while back for $150/hr which included two guys and a 25,000 lbs lift capacity forklift.. it was well worth the cost..
i only paid $1000, i suppose that leaves more money for moving it
moving will cost more than the machine ... yep. Not uncommon..
amazingly cheap for such a machine, 1997 model
Your cost per pound of machine is pretty cheap....
Once you get much above a bridgeport size the cost of machines often falls on broken ones quite rapidly as the cost of movement of them is expensive. Even scrapping them is expensive.
hmm, it's a key way milling machine, that explain the 1300mm X travel and 150mm Y travel..
Good riggers usually earn their money ... Moving machines is tough, risky work.
or look for old riggers who don't look thinner then a pancake? ;)
We hired a man and a big HIAB for £300 I think.
They had a 72 tonne-meter HIAB, so if they can get the truck to within 15m of your machine, it is liftable...
Even a little 20 tonne-meter HIAB could lift your mill from 5m away.
moving stuff around locally is no problem, i have plenty of connections for that
anyone has any sinumerik 810 experience? i couldn't get the controller started up, i think it was because the plc reported a low battery level..
like on a Hardinge?
like on a busch NCNF1 keyway vertical milling machin
look anything like this one http://i47.photobucket.com/albums/f163/johnplctech/Hardinge/P1010023.jpg
yeah, pretty much exactly
the red light with a question mark is lit, the other dark
when i power it up i end up in some kind of plc setup menu
ican do things like "erase plc flags" "erase plc memory"
and i don't know how to get out of that menu..
I had a short on my 24v buss that drew mine down to 4-6 volts and that prevented me from booting up the plc
I also had a dead battery and it was on the back side of the crt box
i get a error message on the battery, but i don't know if that is hindering startup
that is the only error message
I think if you loose the battery (shut down for a long time) you have load the plc back into the control
I have the instructions for that if you don't
oh, i'd like that
there was a ton of documentation with the machine, it's probably in there somewhere
but it might not be the same for a vertical milling machine
where do i find the program to load?
or is it still in there?
I'm not sure what you loose when the battery goes dead

robh__: is the expert on them lol
someone need to slap siemens on the nose for using volatile memory to store programming..
if you have a couple of sheet that have numbered steps with things like "27. PRESS THE SERVICE/DIAGNOSIS KEY ,THEN PRESS THE INITIAL CLEAR SOFT KEY"
that is the start up instructions
if it is like mine was (before I converted it) if you didn't have 24v buss, air, etc it would not boot up
DaViruz, siemns manuals are free online for there controls, it does have all steps listed in there to reload, do you have the files with paramiters etc
i'm not really sure what i have
hey there is Rob! just when you need him
the guy had half a dozen cnc machines and the documentation was kind of mixed up
should have the PLC program also
robh__: are those files supposed to come with the machine in some form?
was it a machine that had been left for some time, as if the battery goes flat your right it does loose everything most time PLC stays, its just paramiters that go missing, ie what the machine has installed
no you dont always get them, but who ever made the machine should be able to give them to you.
yeah it's probably been without power for a month or two
the incoming power line had been hacksawed off..
only 810 i have is a turning control on hardinge no mill but they are the same inside
o the normal way for people to disconnect there machine, chop any and all cables
i guess the price tag if i want any help from siemens is huge?
they are good on support most time i find just need to find someone who knows there stuff.
who made the machine
(never heard of them before today)
DaViruz: is this your machine?
yes, it still resides in the previous owners shop though
are they still going? siemns will send you any files to reload to there default state, you will realy need the one the machine builder used, when they wrote the PLC etc if its fully dead
does it turn on? and bring up the operator screen, or does it come up with some error
i get some kind of plc setup screen
there are options like "erase plc memory" "erase plc flags"
the guy i bought it from had bought it as part of a package from a bankrupt business
Fox_Muldr is now known as Fox_M|afk
h had never used it himself
id try siemens if you cont find busch (google didt find them quickly) see if they can help
like i said if they can send you the PLC and stuff its not too long job to reload it in
while messing around with the control someone decided it was a good idea to hit "erase plc flags"
so i guess even if memory was intact before it isn't now..
johns had bad plc memory we think as we tryed to reload it, now its on EMC and probly runs alot quicker too
a lot better
depends if they went on to erase all plc memory then yes it will be just a paper weight now
i thought the control looked pretty nice, i had no intention of converting it
seems a bit odd though that you could do that from the operator console?
with all keys out
DaViruz: if you determine you need parts for the control I still have my old one
we are used to fanuc here so programing siemns is a task on its own, untill you get back into it as it has its own cycles etc
and for the price of shipping it to you you can have it
DaViruz, if you get some files from siemns and your stuck finidng the manual ill gladly help you out where i can, they take abit of finding online unless you have them already in paper form
i believe they exist in paper form
is it possible to "customize" it myself to suit the machine if i'm only able to get the files from siemens and not from busch?
PLC is all compiled into its own, so with out the source and program to make it you cant alter it
you cant even alter it on the machine
siemens will probly talk you through on the phone also what to do
will he base files offer any functionality at all?
servos and spindle would be a good start
once you put the PLC back in, the main nc should load up then
then you can load in any machine paramiters (how many spindles, axis etc) then you are pritty good togo
how do i load those parameters?
by hand via the operator console?
or do i need to get some file from busch for that?
u can do by hand
PLC you will need RS232
parameters you can do on RS232 also, there are some good free DNC programs about linux and windows
any PC with a comport will do
it's actually easier to convert sometimes than to fix http://i47.photobucket.com/albums/f163/johnplctech/Hardinge/computer04.jpg
[22:57:18] <DaViruz> http://daviruz.meeep.net/sinumerik/DSCF0351.jpg
my control looks exactly like that
i'd be happy to convert if there was some real damage to the default control, or if it was hopelessly outdated
I junked my old broken Heidenhain control, sold it on ebay (with disclosure), retrofitted to EMC and I COULD NOT BE HAPPIER
that stuff looks like a VCR
I've never regretted converting the CHNC to EMC
[23:00:43] <DaViruz> http://daviruz.meeep.net/sinumerik/diagnostic-mode.jpg
that's exactly the screen i get
except mine is in swedish instead of english..
err, instead of italian
I recognoze "macchina" and "password"
i recognize plc also
so it is not bad
DaViruz, in that case you just need its TEA1 settings, TEA2 settings
and SEA and it shiould come alive
ours comes up with that screen if we leave it afew months being off and have to reload it
also, there is a error message at the top saying the battery level is low or words to that effect
they are pritty pricy it will charge up id say if left on all day
what kind of battery is it?
some siemens thing plugs into the back of the control
