ah that one's good for many occasions - "god didn't do it, we did"
I hope that wasn't mean, I didn't mean it to be

well it sure seemed true from where I sit
03fjungclaus 07TRUNK * 10emc2/share/axis/tcl/axis.tcl:
- Added menu entries for copy/paste from/to mdi history
- Moved mdi entry field key bindings to axis.py
03fjungclaus 07TRUNK * 10emc2/src/emc/usr_intf/axis/scripts/axis.py: (log message trimmed)
Adapted mdi history behaviour to results of our discussion on irc:
- Up to 1000 history elements
- Choosing an history element by mouse or up/down+enter will
copy the element to end of history list (instead of moving it
to the end of the list)
- CTRL-H for copying selected mdi history elements to clipboard

Twingy: I discovered that you should add line/arcs to a sketch, not to the basic project. That wasn't obvious. and...
Twingy: I added a 180 degree arc and then another... http://imagebin.org/7085
the new arc began in middle of previous
this maybe 'expected' but kinda surprised me
I'll take a look shortly, working on metric units and getting ready for another release
fixed a few minor bugs
i'll try in metric, but think the problem is in the 180 degree, extruding gave me weird result.... making screen grabs now
yes, the app went away & said BAD BAD BAD BAD... on the terminal screen
don't use metric
(BAD BAD... was from the 180, i didnt try metric )
yes, just ignore that
it's not really bad
it was just a printf from testing
at least gcam doesn't goatse.cx you when it hangs :)
Twingy: maybe this is of use http://imagebin.org/7086
can you post that .gcam file
yep, just thinking bout dat...
I'll take a look in about 10 minutes
it's binary. how to post?
I usually place my files on my webserver
do you have a webserver?
otherwise you could attach in bugzilla
file a bug
and use attach file
I knew I forgot something
let me add that versoin to bugzilla
ok, go ahead
but i see more info... a 2 element shape of a single 180 deg arc, closed by a line ( a diameter), does similar, the whole shape disappears... going to bugzilla now (new territory for me, dont wait for it :)
I don't think I will have a new release until wednesday
getting decent conversion between metric and imperial is a bit time consuming
gotta update the bounds on all the widgets
otherwise you'd be stuck with little 100mm x 100mm work spaces
100 inches x 100 inches is plenty
plus the gridding has to change
it needs to be cm->mm->0.1 mm
so it doesn't start at the base unit
anyone know what E.S.T. stands for, in regards to movies at theatres?
something seating time?
I dunno what it means.
I should call the theatre tomorrow and ask.
eastern standard time?
I know it doesn't meant that.
apparently in spanish it means STD
Twingy: there is no 'attach file' on the gcam bugzilla page (http://gcam.js.cx/bugzilla/enter_bug.cgi),
and, while the bugzilla faq says Just click on "Create an attachment". that doesnt exist either
* Twingy takes a look
Twingy maybe you can just make a 2 element contour with a half circle closed by a line. that will exhibit the symptom
you have to create the bug report first
then if you view it there is a Create an Attachment link
ah. that's intuitive :)
I'll take a look
ok tomp, I see it
I'm pretty sure I know what that is
metric is half done now
think I will finish up tomorrow
bug report created, file attached & sent now, g'nite & thanks

Hello, i've added a PCI parallel port card to my PC. I'm looking for ways to check if it's running ok. (noobie)
[08:18:28] <alex_joni> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?NetMos
those are the most common I know about
hmm back on that embedded geode computer project now, and for the next year it seems
I need to find something to do with mine..
don't need to control anything ?
hmm you could always create a "house control" computer
get a couple of those ethernet over power cables thingies and control all your stuff from your embedded computer :D
I'll reconsider that when I'll settle in :D
embedded computers are only really needed for mobile stuff imho
if you're designing an industrial system you probably want something designed for the task
Dallur, atmel with an ethernet connection, and you're more than set... PIC/atmel + wifi, you're wireless. :)
atmel won't run an 802.11 protocol, no way
fenn, they have other chips that do, I believe...
have to struggle just to keep up with regular ethernet
(i dont consider a microcontroller a "computer" even if technically it is)
[08:35:03] <A-L-P-H-A> http://atmel.com/dyn/resources/prod_documents/AT76C515A_DS_5677AS.pdf
so you're going to interface your microcontroller to an 80mhz arm controlling the wireless :D
who knows. :)
just as long as you don't go that "X" modular crap
only comes in bga
ffs you need an NDA just to get the datasheet?
fenn: there are plenty that run wifi
but atmel makes arm's too :)
no reason for an arm7 not to work with wifi
what i meant was it makes more sense to just use the arm chip in the first place
[08:39:38] <alex_joni> http://www.ethernut.de/en/hardware/enut3/index.html
ethernut is kinda crazy for most things
[08:40:21] <alex_joni> http://www.ethernut.de/en/wlan/index.html
fenn: why do you say that?
well, you might as well just get a ts-7400
and run debian on it
you dont need all the extra stuff just to get on an ethernet and send/receive data
I'd probably get one of these: http://www.olimex.com/dev/sam7-ex256.html
color lcd is an interesting touch
why is olimex's website so lame?
fenn: guess they stick out with grood producs/services :D
fenn: that's prolly a lame excuse :)
hang on.. I have a nicer one :)
just to find the damn link
i guess i just like ts-7200
wonder how emc would run on that ..
rtai has some version working for arm
oh, but that's for ARM7 :(
the fox is also nice

hello, what is the application?
i have two apps in mind specifically, one a humanoid robot, the other as a wearable computer
can't you wear a humanoid robot?
err.. carry :D
if you're wearing it, then it's not a robot now is it?
I saw a deme of the sony dog the other day, quite funny
Morning Chaps! I am trying to source a 0 - 180V DC motor controller for a Denford Starmill but I do not know the HP is there a way of determining this?
lerman_ is now known as lerman
have no clue, is there a desent motor plate?
paragon36: do you have a current rating?
It does'nt disclose the HP and I cant see the Amps as the label is partialy hidden
bring your mirrors :)
just get something ridiculously oversized :)
10kW oughta do it
I think about 1 amp but not sure due to it being hidden .... yep
are you refitting the denford?
if I am reading the denford docs correctly, it has a VFD on there already
(been researching a denford lathe)
ds3 In my haste I shorted the leads for the varible control to the Denford DC speed controller I am currently trying to debug the system but am at a loss. The unit uses 2* SCR and 2* op-amps. The op-amps have 12V supply but I am only reading 3v max at the inputs where a pot would be connectected to control the speed
VFD = Voltage Freq Drive?
Variable Freq Drive; they seem to have a 3PH AC motor on there
have you looked to see if the schematics are posted on their website?
This motor drive used to output 0 - 180V DC to the motor not AC. It takes 240V AC in
hmmm different system then the lathe
I think the motor is a Baldor (or something like that)
I am not familiar with this type of drive but from what I can see it uses 2 op-amps which in turn switch 2 SCR's which in turn send the chopped AC power through rectifier diodes to produce 0-180 VDC does this sound about right?
probally a the op-amps are setup as comparator to trigger on varying voltages?
I am currently attempting to desolder the op-amps as I have bought some for replacement. Would you agree that these are probably the weekest part of the circuit?
I'd guess the SCRs
op amps are for current limiting
fenn: as in reading a sense resistor?
hmmm can't find the zip file URL on their site for the mill that I dl'ed by mistake last time
Current Limmiting! What would be used to pulse the SCR's I cant see any other components on the board other than resisters (lots) some diodes and caps?
maybe they act as comparators too
fenn: how'd that work with an SCR since the only way it can turn off is if the AC line dips below 0?
To determine the voltage the SCR's would be triggered late for lower voltage and early within the AC cycle for higher voltage output. Is this correct?
dunno, this is not the best way to reverse engineer a board
paragon36: I'd suggest you post to their board
they actually are willing to answer q's for machines of that vintage
Do they have a Forum now?
[09:55:07] <ds3> http://www.denfordata.com/bb/
Excellent Thanks Chaps I'll give it ago.
if they still have copies of the docs/diagrams, most likely they will scan and post it
Would this work ok? http://cgi.ebay.co.uk/KB-BALDOR-BC142-3HP-DC-MOTOR-DRIVE-W-HEATSINK_W0QQitemZ290016457393QQihZ019QQcategoryZ1267QQrdZ1QQcmdZViewItem
doesn't say much about the control signal or isolation
Sorry got called away! True it does'nt. BTW I have seen some drives but looking at the spec sheets they talk about comutator (2 wires) and motor drive (2 wires) are these for brushless DC motors?
could be for variable field motors
So no good for my purpose then.
universal motors I think

good morning awallin, Dallur
hello rayh :))
What you doing these days?
rayh: these are very strange days
listen music and fighing
a bit of relax :P
too much things to do, too few times :(
so.. taking a pause :D
I know something about "too few times"
I just received a mail from a guy in palermo (IT), he was asking about CNC, i sent him here few days ago
and lot of time I can't see jymmm here around
Hey jackey - long time no see.
hi skunkworks !
giacus, jymmm hasa new job, and works nights
oh - hi :)
what job ?
some computer / IT maintenance thing
ok, nice to know he's good
well, I didn't say that :)
right, I sayd that
oh boy, I made another blog with etch cnc. http://www.makezine.com/blog/archive/2007/01/etchasketch_cnc.html
heh - you're world famous
and so yesterday accounted for 19% of all hits on the axis website
er, all hits this month
impressive, considering that the month is just about over
wanted to ask you something
it just means there normally aren't many visitors
do you know of a good survailance solution on linux?
like security camears?
jepler: where you personally contacted by the ohio arts legal department?
alex_joni: yeah I found one before
www.freshmeat.net has it..
but I didnt get it to work as it depended on ancient deb packages
skunkworks: no, not yet
skunkworks: though I heard of someone who had trouble, and put this text on my website from the start: The Etch A Sketch® product name and the configuration of the Etch A Sketch® product are registered trademarks owned by the The Ohio Art Company. None of these trademark holders are affiliated with the AXIS website.
jepler: I was looking at the bottom of this site ;)

awallin: I don't think "planet" integrates with anything
hi, is there a EMC2 version of the MS-Windows tkemc/emcsh.exe ?
no, but an old version will probably still talk to emc2
I tried and it doesn't seem to work
tcpdump shows the Linux EMC server getting the packets
there are good solutions for running X programs on windows displays now, in particular vnc
I turned on debug on EMC on the linux server and it does talk for a while but then the client declares no connection
maybe that's a different/better approach?
Yes but for this specific case it isn't a solution
my goal is to run emc2 on an embeded linux board with limited resources
Nicolas35LA, have you looked at Eric Johnson's "emctelnet"?
I want to only run what is necessary on the embedde dboard
or was it emcrsh?
I think he decided to call it emcrsh
yes I looked at ti
Nicolas35LA: all you need is time, expertise, and the source code to build a new emcsh.exe. We provide the source code
basicaly what I want to do is have the GUI run on Windows/Mac and talk to the linux server with NML
I am looking for examples to play with and get familiar
I satrted with tkemc
I have time and expertise
have you done this before with an earlier emc?
time is not a problem but before I jump I wanted to know what is done already to not reinvent the wheel
how did you solve the problems with the different systems finding the same ngc file?
there's a Java client, though I'm not sure of the status (I think it's pre-pre-pre-Alpha :) )
I first copy a tmp file to the server
editing is done on the client
the tmp file gets copied at run time
hmm - the client you use(d) with emc should be able to talk to emc2, with some .nml file changes
(I think ??)
I think so too - sounds like you'll have to debug some more
This works in EMC1
but probably interfaces have changed in EMC2
we've changed the layout of many of the classes
the stat class most of all
that explains it
maybe you should begin by using linux on both machines, just to make sure the network transport hasn't bitrotted completely
I can do that. But it works fine from MS-Windows to Linux on EMC1
It must simply be differences in interfaces
I need to start from scratch it seems
you may be able to start from a recompile of the windows client ...
ie, port over the changed status and other things, and see where that gets you
I was also considering using the emc.so that comes with Axis
not sure how difficult it would be to port that to Windows
windows + .so = boom!
I said Port ;)
cygwin might help
not in this case - it's beed covered
I don't know why it would be much harder or easier than the tcl library
but if you want to run axis, you'll also have to make sure togl (the tk opengl widget) works on windows
seems like a nice solution I can then use python on Windows to create a GUI
or maybe run Axis :)))))
Nicolas35LA: are you tied to windows for some reason? if you don't need windows, you could even run perfectly well using just a live CD, no installation necessary
I think your concern about "reinventing the wheel" can be laid to rest :)
Yes, I am no fan of windows
but I need to
I understand, but sorry I am not able to suggest anything but "start compiling stuff"
as far as I know, emcrsh is the only truly remote UI for emc2
everything else just runs with a network connection beween the UI code (still running on the EMC box) and the display
I don't understand the distinction
vnc / remote X are basically the same thing as a KVM switch with a long cable
the software still runs on the emc box, but is shown elsewhere
with his approach no gui code runs on the emc machine
ehm. one can run an X server on a Windows box
dunn'o how it'll do with OpenGL
cradek, right - that's different from vnc/remote X, since those still run the user interface on the EMC box, but use a separate machine to actually draw the pixels
erDiZz, I've used Axis on cygwin (with an old Parhelia card), and it works well
SWPadnos, you mean that X server which comes with cygwin?
Did you use Axis to control a remote machine
erDiZz, yes, cygwin/X
Nicolas35LA, yes, but without an actual machine attached
ok, so axis was running on linux but displaying to a remote Xserver on windows
I frequently run AXIS using the X protocol for remote display
Nicolas35LA, that's the distinction I was trying to describe
I don't think (m)any people are using NML over the network
our linux embedded board is small. I don't know about the extra load it would put on it
I might try it
what processor does it have?
pluse train generated in hardware
do you have RTAI / RTLinux compiled for that?
sounds like a neat little gizmo
is this the Mesa 4C81?
yes, rtai is there
cool. can you point me to some code / instructions on getting that installed?
the linux bpard is a daughter card to our ARCNC100
I'm going to be getting a Mesa 4C81 (which is pretty similar, it seems), and would like to run emc on it
I'd love to see patches to support ARM incporporated in our CVS tree
[19:52:39] <SWPadnos> http://www.messanet.com
if you haven't heard of them
SWPadnos, what's the price for 4C81?
$300 or so
$260 + $55 for a 400k gate FPGA, in single qty, with 64M RAM and 64M flash
yeah - I should call them to see if they're in stock again
well, thats my experiments for the evening done
today I was experimenting with cats and parcel tape, to try and reproduce that video we noted on YouTube
do they still have claws?
all cats have claws
anyway, the results are:
not all cats seem to be persauded to crawl along the floor, just because they have parcel tape on their back
giac_awy is now known as giacus
that just sounds wrong.
laser pointers are the best cat toy.
it's only fun until someone loses an eye
our cats think ceiling fans are birds of prey
What does the bleeder resistor do in an unregulated linear power supply?
it bleeds off capacitor charge, so you don't get shocked a few days later
owad: ensures that after mains power is removed, any smoothing capacitor drains down to near 0V in a short time
or, what SWPadnos said
How do you determine how much resistance you need?
you decide on how long you want it to take to discharge (maybe 5 to 30 seconds or so), look at the voltage, and use the RC time constant formulas to pick a resistance
and how you define "discharge" -- under 1V?
also, you have to take into account the current the caps are meant to supply
for example, deciding that discharged means "<12V within 30 seconds" , and starting with a 48V supply with 12000 uF caps
I ordered the parts I needed to build the power supply a few months ago, but now I can't find the bookmark I used to figure out what I needed, which is a bit of a mess.
owad, what is your supply voltage, and what caps do you have?
the power supply is 24V
(one for each stepper)
the caps are 50000uF (two for each stepper)
and then I have a rectifier bridge
The drive is a Microstep from EAS
is that 50000 uF total per supply, or two x 50000 prer supply
two x 50000 per supply
that sounds like way more than you need. what current are the motors?
robin_sz: my cat runs sideways when he has tape stuck to him
they're the 240 oz/in from homeshopcnc
ok. I only see a 260 - wasn't sure it's the same
oh wait, that's what I'm looking at too
checkign what I really have…
it's probably very close to that
yeah - it's the 260 oz/in
when I ordered the parts, I was following a schematic and formula in a pdf for another similar stepper drive
hmmm. the formula Mariss gives (which is pretty reasonable) is that you need 80000*I / V uF caps on your supply
(technically, that should be 83333 *I, but who's counting)
that gives me 8666 uF for you, not 100000
you runthe risk of burning up your transformer with that much capacitance, unless I'm missing something
hmm… I recall the pdf I was looking at gave a recommended range, and I went on the high end, thinking high capacitance would just guarantee all the more that the voltage doesn't drop
it's counterintuitive, but too hig a capacitance can destroy the transformer
but it wasn't _that_ big of a difference
too much inrush?
not inrush, but continuous operating
every cycle, the transformer only provides current once the voltage goes above the cap voltage. all the power being used has to be transferred in that small percentage of the cycle
if you decrease the conduction phase (by increasing capacitor "stiffness"), you have to increase the transformer current
since heating is I^2 * R, you get a square-law increase in heat, and a linear reduction in time, so you have a net linear increase in transformer heating
I know I've got some smaller capacitors down in the garage. How much leeway do I have in capacitance?
probably 0.5x to 2x or so. I may have screwed up some decimal point somewhere, but you may want to look at it again
it changes the output ripple
'off to find one. Thanks!
hopefully it's actually a help, not just extra work for you :)
one cap that's rated 8,600 uF
one that's 4,200
and for that are 6,300 uF
so the 8,600 is a no-brainer
do you think I'm better off with 6,300 or 10,500 for the other?
owad_, depends on the current you need. the 8666 uF calc was from a current of 5.6A (2x2.8) - you probably don't need that much, so the 6300 should be fine
were you calculating for both motors?
I thought each supply had one motor
ok. the current is 2.8A, and depending on the driver, you may have full current in one phase and some in the other (half or 1/sqrt(2))
using Mariss' formula, 80000 *I / V, I get 80000 * 2.8 / 24 = 9333
hmmm - I wonder what I did last time to get 8666 :)
ah - I mistyped 2.8 as 2.6
my transformers are rated at 24v, 10A. Do you think I need both?
I'd say probably not
Any harm in using one power supply for both motors (I can't remember why I wanted to do them separately)?
if you do go to one supply, then you probably want all 3 capacitors on it
anyone know what happens if you drive a standard induction motor designed for 50Hz/3000rpm at higher frequencies? I would want up to about 6000rpm or 100Hz
I don't think so. that's what most people do
You mean 3 6800 uF's?
awallin, you probably destroy the bearings
SWPadnos: but electrically, are there any problems?
6300 uF, actually
owad_, oh - you had written "for" - you meant "four"
Most newer motors will allow 2x frequency. Some even publish ratings at over frequencies.
owad_, a total of between 17000 and 20000 uF should be good, so three of those would probably do it
any tips on testing caps? I don't know where these came from
awallin, the only trouble might be that you need higher voltage to get the same torque, which is higher total power
I'm using a cheap V/f VFD right now, but the torque drops off really quick after 50Hz. I'm thinking with a vector VFD I could get the higher rpm and good torque ?
owad_, nope - electrolytics sometimes die and I'm not sure how to look for that without a scope
I think these are new old stock
awallin, right - you get constant torque (current) below the rated frequency, and constant power above
in the constant power region, you need to decrease torque as you increase speed
ok, but above the rated speed, would a vector VFD help, or am I power limited anyway and torque will drop off
you're power limited anyway, and torque needs to drop off
that will vary somewhat from motor to motor, but the general rule is to not exceed the power rating
awallin; your blog is broken for me on your noux pics entry
the image is over the text
ok. It's just that all the standard industrail motors are rated at 3000rpm, and that's a little too slow for small endmills... so I'd like to find something that goes to 6000rpm.
lerneaen_hydra: can you paste the url
[21:57:00] <lerneaen_hydra> http://www.anderswallin.net/
I've got to run. Thanks for the help today.
awallin, yes - as Ray said, some motors are rated to go faster than their synchronous speed
[21:57:19] <lerneaen_hydra> http://www.anderswallin.net/2007/01/noux-pics/
if you want to buy a motor, look for "inverter duty"
FF and konq
firefox 184.108.40.206 works for me
lerneaen_hydra: ah, yes it's "broken" over here also
lerneaen_hydra: it's even more broken with ie...
lerneaen_hydra: yep, that's what I get too. Looks like browsers don't like the way wordpress positions pictures. better to just have them plainly in the text, and not aligned left or right...
SWPadnos: I'm wondering if a big DC servo might be a more straigtforward solution for a ca 1-2kW spindle that would go up to 6000rpm
a big fast servo of some kind may be the answer, if you need to control the speed electronically
this is why it's still a good thing to have a pulley set - you get full power in all the speed ranges
bah, g'night all
SWPadnos: yes, rigid tapping would be on the wish list sometime in the future.
lerneaen_hydra: I fixed that particular page, but there are probably more
pulleys wouldn't really fit on our small spindle-head...
it's kind of hard to get everything you want out of one motor
a DC (or AC) servo has a particular power rating at some speed
below that speed, the power decreases linearly - it's actually a torque rating
yep, on the minimill we want to do from 40mm face-mill down to 6mm ball end for 3D finishing, quite a large range of speed/torque requirements
so if you want a spindle that runs from 60 - 6000 RPM, you're basically going to have 1/100 the power at the lower speed (since the torque is constant)
there's no way around that unless you use a mechanical speed changer
(of course, servos can give peak power that's much higher than continuous, so it can work out in the end ...)
how much does changing from Y to delta winding on an ac motor help?
in the low rpm range
I have no idea - you'd have to ask someone like Ray or jmk
I understand this is how the pros do it
(I only know the theory on those - not application ;) )
how do you differ from a nullmodem cable and a normal serial cable?
some wires are crossed in one type and go straight in the other. google is your friend :)
I were wondering if anyone knew
on a 9-pin connector, pins 2 and 3 are crossed for a null-modem and straight through for - err - straight through :)
I think it may be the same pins on a DB-25
I have a db9F to db25m
(but opposite meanings)
but I dunno if it's a nullmodem
oh, then you'll have to look it up ;)
that's meant to connect a computer to a DB25 modem, I'll bet, and won't be null-modem
i'm studying industrial engineering and i started "fabrication processes" (don't know if that's the name in english). and i might need a software which helps me simulate some machine functions
i would like to know, if emc is also able to simulate what the machine will do if i enter the codes, or if it's just a machine-communication backend for linux
josesito: well it will draw your toolpaths
anonimasu, thanks for the answer. i can use it for testing purposes in my home (withouth the actual machine?)
you can "dry"-run the machine
what is that?
and preview the movement of the virtual tool
run without motors attached
josesito: the simplest thing to do is get the Live CD from linuxcnc.org, boot it (it doesn't need to install anything), then start emc from the menu and run the sim/axis configuration
what are the requisites for compiling??
get the livecd..
that hard to compile?? :$ =)
not worth the trouble
it may be easier when you just want to run sim
josesito: the list is a bit long for compiling..
tcl,tk, gcc, python, etc
it's just i don't like getting out of my system just to run the program... can i at least get binary packages and run it without installing?
btw. i'm running archlinux
josesito: what system are you running?
what kind of packages does it use?
it has it's own package managment system
i'm looking for it right now
there are binary packages for Ubuntu only
I guess you need to grab the sources, and use the usual ./configure, make, sudo make install
i'll try that
just another thing
you will want ./configure --enable-simulator
where can i learn more from the language??
as you don't have a realtime kernel
josesito: the User manual is quite good for basics

Hello All... Would this controller be OK for a 180vdc motor that only has + - gnd cable?
[23:06:34] <paragon36> http://cgi.ebay.co.uk/KB-BALDOR-BC142-3HP-DC-MOTOR-DRIVE-W-HEATSINK_W0QQitemZ290016457393QQihZ019QQcategoryZ1267QQrdZ1QQcmdZViewItem
does this link work for anyone?
[23:06:59] <alex_joni> http://www.uclinux.org/pub/uClinux/dist/uClinux-dist-test-20070108.tar.gz
(by work I understand more than 5kB/sec)
The ebay link Alex?
paragon36: no, the uclinux link I posted
Ooops sorry I have a delay on this connection ... ;-)
alex_joni: I started at 9KB/s but it is decreasing .. down to 6KB/s now
argh.. that is such a crappy server
I think it limits download speed on purpose
paragon36: looks like there are specs here: http://www.baldor.com/products/detail.asp?1=1&catalog=BC142&product=DC+Controls&family=OneWay%7Cvw%5FDCControls%5FOneWay
I was alittle confused regarding the motor connections as the diagram has for wires from the motor?
Armature = 2 connection | field winding = 2 connections?
paragon36: I dunno, there doesn't seem to be much information about these controls...
Being trying to get this motor controller working that I blew the other day.... got the 12 v suppy working but am seeing 240V dc on the motor output. have replaced the op-amps, SCR's, Rectifier ... but its no go ... So was asking group about a driver ive seen on ebay.
Yeah I'm a little confused to know if this would work on a normal 2 lead dc motor... I dont understand the armature and field winding connection.
Should ask the seller the question I guess.....
alex_joni, if you want to put it on linuxcnc or cncgear, be my guest
Thanks Jepler for your help anyway Jepler :-)
Err pls ignore my poor, poor grammar!
paragon36, if it has armature and field connections, then it's for a different kind of motor than a "standard" DC servo
I don't know if you can make it work, but it may be possible
SWPadnos: found a faster mirror
someone like Jon Elson or John Kasunich may be able to tell you
but I must say I find uclinux insane
their latest package decompresses to 1.2GB
that's not exactly micro, is it?
not my idea of a small system
Thats a shame SWPadnos as the price is good.... BTW what sort of motor would it be called?
you compile all that into a krnel which is 1MB at most
I can't remember - that's why I was vague about it ;)
omg.. it even has samba
it looks like they've included everything that works on uclinux, and you can select the packages you want for your own device
so it is pretty small compared to the many-gigabyte archives of stuff available for e.g. Ubuntu :)
oh darn.. of course it doesn't work with 2.95.3 anymore
and the toolchain I have for arm is 2.95.3 :(
just about to order a motenc
was wondering between the motenc lite
the cheaper one doesnt have the ADC inputs
and only 4 DAC outs
is that likley to matter with a 3 axis mill ?
