damn.. 4 L298 burned today !
all in the same controller ..
can be the ground ??
i'm using 220 V whitout center ground ..
through an isolation transformer ?
is there 220 V - 24 transformer
Put a tansformer in there before you get yourself killed.
Power supply ..
OK, so you do have a transformer in there...
for power supply , out 32 V
i worked all the week to finish the box ..
today, turning on the drivers, first l298 burned on z axis
i checked cable motor with an ohmeter, it seem ok
looking for some test circuit to check L297-298
seem not exist :(
the only way to check l297 seem to be replacing it in a working circuit..
anyone want to see a nice video ?

hmm, CR750 didn't come back
is that a motorcycle?
probably, but that's his irc nick
a guy I'm trying to help
Well shit... I can get 90IPM via Mach2
any faster and it stalls.
this is driving me nuts.
I need a scope =(
Jymmm: you can get a "good enough" scope for $20 at any hamfest
fuck it... I need a drink!
cradek maybe a 300 lbs scope
Jymmm: you will probably have to recap it and maybe replace a tube or two
they are goin for $125
actually I dont need a scope, I need a clue or tow
brb... getting some irish coffee
that may cost more than $20
damn.... a lil strong
did you bring one for me?
yep... in a 64 ounce mug
Hope you like Courvoisier
Hope you like Courvoisier
* Jymmm hears cradek googling...
no, I'm watching Jacky^'s video
heh, that's pretty cool
but somewhat out of tune sometimes
I doubt the tuning is closed-loop like with meat (humans) playing the flute
seems like that would be "easy" enough to add, though, considering what they accomplished already
Eh, well until I get mine up and running, I dont care! lol

yay, another stupid instant messenger
that probably does almost all the things that irc has done for 10 years
oh, it's voice
I take it back
ANd it works with any client, not just googles
but who wants that?
you can use gaim if you like
oh yeah.... this coffee tastes GOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOD!
I dont' know... al alternative network maybe
heh... Could you imagien VoiceIRC ?!
cradek how much milling do you do on avg per month?
probably only a couple hours
oh so not your first hobby huh?
I have more hobbies than time
and I usually just don't have anything I need to mill
I just put new leadscrews/leadnuts on my mill last weekend
acme zero backlash
ah, very cool.
One of these days I'll take apart the nut on my z axis and take some shots. they did a good job on it I feel.
is it reliable to drive two stepper motors synchronously with two separate l297/l298 drivers on the same axis to get more power?
err, i mean l297/l293e
DrZimmerman, why not just gear it up?
A-L-P-H-A: i would use gears, but i don't wan't them to run too slow
A-L-P-H-A: it's not for a cnc machine, the should switch a gear for a bigger motor
A-L-P-H-A: and i got my hands on lot's of l297 and l293e for a good prive
A-L-P-H-A: and the l293e can only drive 1A
DrZimmerman. oh doing it for cheap, and doing it right at usually seperate things. but if you can, sure... but I don't suggest it.
what happens if one of the motors skip?
you'll get jamming.
A-L-P-H-A: this is exactly the reason why i'm asking this question :)
my suggestion is get the proper sized motor.
A-L-P-H-A: if one motor makes a phase slip, then they will slip eachother
that's the easiest solution... not the cheapest... but it's the best.
DrZimmerman, I don't know exactly what will happen, but I'm imagining bad sounds will happen.
I do'nt think magic smoke will come out... but couldn't be good. could be 'okay'.
probably i will do a prototype and test it
anonimasu, think it's bad, if I talk to my exGF and call her Ms. Evil?
because the step motors only need to run when they switch the gear of the bigger main motor
well, if one motor skips, you're going to cause extra friction on the other motor... unless there's a lot of play.
is this for speed controlling?
the main motor has a magnetic coupled gear
AC or DC?
rheostat it. or PWM it.
google rheostat speed control or PWM speed control.
and the reason why i wish to take two step motors to switch the gear is because the coupling magnetics are very strong
A-L-P-H-A: not really
but she might think it's bad
anonimasuo, well... that's how I'm addressing her... and I'm begin called "goodie good". strange.
I'm calling her Evil, because I think she is... but I don't know if she thinks I actually think she's evil.
why is she evil?

I am using BDI 4.23 and Jon Elsons Universal Stepper Controller and I have a problem
I am getting an error when I am trying to muve some axis:
It doesn't work...
Issuing EMC_AXIS_JOG -- (+124,+24, +9, +0,0.750000,)
Issuing EMC_AXIS_ABORT -- (+120,+16, +10, +0,)
axis 0 following error
bridgeporttaskintf.cc 1020: Error on axis 0.
Issuing EMC_TASK_PLAN_SYNCH -- (+516,+12, +0,)
emcTaskPlanSynch() returned 0
Heard the same from Tim Smith on the user's list this morning...
What version I should use?
If you want the current stable Debian base, BDI-4.23 or later.
if you are happy with an out of date Debian base along with a broken package management system, then BDI-Live with Jon Elson's hacks
the alternative is a vintage BDI-2.20 that doesn't get any support.
I would like to use 4.23 but I also would like to have my USC board working
In that case, you need to badger Jon Elson... I can only do som much without having the hardware to test on.
unless you know C...
I think I do not have enough experience in C
Do you have any idea what is wrong? I could try to trace the problem.
It sounds like a bit within the USC is not being set, so it is going to be a software issue rather than hardware.
Do you subscribe to the emc-users or emc-developers list ?
I have been watching only the archives. Perhaps I should subscibe.
Yes - Then you can ask Jon why he doesn't use IRC & bug him about his drivers.
bluetooth wirless connection to a phone running a whoppin 4.5 kBps
I just subscribed my self to both email lists.
ug, another gmail.com addy
gmail is better than the other free web-based mail services.
Except no folders =(
it has something that is nearly functionally equivalent
I dont care for it. I like to get crap out of my way - thus folders.
I use gmail, I just dont like not having folders.
well I don't use it either, but some people want web-based email (?) and it seems like a good solution for them
I have a few gmail acnts, but I would prefer folders and tell them that. anyhow....
how goes it?
oh fine - nice to have a long weekend
heh, untill you said that I forgot all about a holiday coming up. Sometimes I wish places stayed open on holidays, then I cold get some work done.
but a holiday where everyone but Jymmm has to work would not be a holiday
True, that would just make Jymmm a lazy bum.
paul_c: Hey, I resemble that!
oh, under mach2 I was able to get a solid 90IPM
on a 366MHz Celeron ?
On Fuji... P4 2.8GHz
Install Linux on that, and we will probably get a similar speed out of EMC
oh hell no... I might consider that but you said I had to keep /boot on a seperate partion
no I didn't
m$, / + /boot, /swap
and you said no!
Just /boot, /, & swap - Don't need an NTFS or FAT32 fs on it.
The hell I don't!
/boot and / can be combined....
ok, on a serious note....
I had installed W98, then tried to install emc on the other laptop. When install was complete grub wasn't able to rewrite the MBR and wouldn't boot up. On the cd I didnt see any recovery mode. any suggestions?
<serious hat on> Lunux can be run in a single partition with or without a swap (as long as you have plenty of memory. </>
grub shoud have been able to write the MBR....
linux kernel has been able to swap to a file for a long time
I am having 384Mb of ram on my EMC machine. Is that enough or do I need to have tha swap partition?
Yes, it should have, but it didn't. So I rebooted off the cd and looked for a recovery mode but I didn't see one.
sure. Swap can be a prtition, a file, or even memory.
all machine should have some swap. Then when something goes wrong you say "why is my machine swapping?" instead of "why are my processes dying?"
reasonable ulimits can't hurt either
Jymmm: At the boot prompt on the CD, try "linux append=rescue"
paul_c: Would you like to use my EMC machine to debug the USC problem? I have USC board attached to it and the machine have Internet connection with public IP.
Or someone else?
paul_c: I'll try it on a P3 733 I have with a 810 chipset. Jim no like mucking with Fuji... Nice and stable.
can you try installing in expert mode and use the noprobe option..
Martzis: It is a tempting offer...
how did you guess.
I thought anon resolve the problems he was having mostly by shitching the BIOS LPT settings
les : are you here?
waho... where did gezr spring from..
ive just been watching
* Jymmm shows paul_c the rock that gezr was udner
Jymmm: You take the left, I'll take the right eye.
The communication with Universal Stepper COntroller board seems to work bacause I can turn the spindle on and off and it will alse read the estop button status.
* gezr is blinded
gezr PH! WISE GUY EH?! YUK YUK YUK
Jymmm : hey, I try :)
It's a driver problem rather than hardware or wiring with this USC
Well, why doesn't Jon, get his butt in here
does it matter if the parallel port is enabled via the kernel, instead of used as a module? that would remove the module loading and such?
Jon said to me in email that he will be travelling for few weeks
I've always felt that it should be the HW mfg that should resolve any driver issues.
but then again, no module and no kernel support would be the best situation alltogether right?
but J.E. reckon's it's my fault that, despite being told not to use i810 MoBos, the BDI-4.xx won't load on to a pile of Dell junkers he picked up cheap.
oh, my friend has his hurco milling machine running mach2 right now
he used zylotex modules for it, and some vfd drive for the spindle
ill build an emc box to take down to him to try it out, he isnt very computer savy at all
didn't think Hurco made a machine that small...
its not a small one :)
I liked the feature set of Jon's board, except for the fact it's proprietary. I no longer do proprietary in any way, shape, or form.
it doenst have a tool changer, its the manual change model, but its a sturdy machine
paul_c: which one of those parallel I/O cards would you suggest? That one company is only 45 minutes up the road from me.
robin_sz: I got an RCM-3700 Dev Kit & am waiting for hardware from Mariss
mshaver: kewl. they are nice little boards the rabbits ..
Hey, Matt is awake!!!
mshaver: grabbed the source from sourceforge yet?
steve_stallings: But no skype, so we can't bug him verbally.
It is a local call for me, whadda you wanna me to say?
I was in NYC all week, I could have waved.
Martzis: Suggestion: Set up a box with a full install, and may be we can have a look at the driver sometime.
you guys are on skype?
* mshaver is somewhat awake...
robin_sz: I did a CVS update a while back, but I'll keep current as soon as I get the G101/102 from Mariss. Right now I need the Gxxx to power the Rabbit module so I can load code
right, I havent put anyting new into CVS in ages
LawrenceG, les, alex_joni, Jacky^, Jymmm, mshaver, & me.
paul_c: Ok, I have almost complete install at the moment, but the hd is quite full. I will install bigger harddisk perhaps tomorrow.
I was talking about teamspeak 2 years ago
paul_c : maybe sometime ill join the conversation
ive ran, teamspeak, and ventrillo
Martzis: 4-6Gig is plenty.
Martzis: 4-6Gig is plenty.
Yes, the current hd is less than 2
what speed the CPU & how much memory ?
800MHz P3 & 384Mb
plenty fast enough.
I had to use small hd bacause it was my only parallel ata drive (Machine does not have sata controller).
BDI-4.xx doesn't support (or isn't tested) on sata drives.
it might work, but no promises.
I noticed that with my other PC. Atleast VIA's sata chipset does not work. I have not tried with my SHuttle which uses Intels integrated Sata.
you want to try and avoid anything with integrated video that shares main memory.
paul_c: oh hell man.... Like I know how to program a FPGA, much less anything else!
It has integrated video controller but i think that it does not use ram
Jymmm: well... send it to me for programming.
paul_c: If I did that, I'll never see it again!
sure you would.. I can set up a web cam for you..
Jymmm: didya download that iso ?
paul_c: Could you send me some email. I will reply to that with ip & u/p to my EMC machine tomorrow. My address is email@example.com
paul_c: wasn't done uploading when I went to sleep last night.
paul_c: Got MD5?
Martzis: Meet anonimasu - He is from your neck of the woods...
burn a beer mat, and then use "linux mediacheck" @ the first boot screen.
Md5 is to PREVENT making coasters!
mshaver: I presume your intention is to write a driver for emc, using ethernet to talk to the G200x?
robin_sz: Basically, yes.
mshaver: as am emc2 HAL module?
Jymmm: In a bit, I'll have your beta-bitch.sum
robin_sz: I just looked at Sourceforge - Is there a CVS, or is the alpha3 file the latest code?
alpha3 is the code steve released
HEAD is however badly I have screwed with it
basically, You'll not really need much of it at all
al you are going to do is write the velocity word to the step gen at interupt rate
robin_sz: It depends: If we take advantage of the real time capabilities of the g-rex, then the likely path is EMC(top end)->NML->G-REX
robin_sz: So, there is a CVS? I didn't see it linked from the project page
ahh, yes, wait, I'll re-enable it .. I removed the link while SF deleted a zworld file I accidentally included :)
robin_sz: If we use it as a "dumb box", then it would be a HAL module - But at the moment I'm inclined to take the path of least work!
so you would basically have the interpreter on the PC, and push motion commands down to tthe grex?
OK, cvs link re-enabled
robin_sz: yep - We could then do a Windows version of the EMC - not that it would be the "real" EMC without real time
for many people, that would not be an issue
it would also make a linux version of emc simple too
without the real-time part ..
just a static app and a g-rex
people could upgrade to the "real emc" after getting a taste for it
yes, it's kind of neutered though... Real real time is somewhat our claim to fame - But yes, it would be a good introduction into what's possible!
whatever, Windows ability, no matter how loathesome, would increase the potential userbase by an order of magnitude
Jymmm: md5 sum posted.
and there still is real time, its just not on the PC anymore ...
I'll admit that I have greatly underestimated the "appeal" of a Windows program - I personally use Linux for everything (desktop, etc), but I suppose I really am in the minority...
mshaver: so basically, you'd dump the G200X gui, delete the emc interp from the rabbit, and replace interp bits with an NML interface ...
I haven't looked at your GUI yet, so I wouldn't say that - or really any of that - I want to see what you guys have done & take maximum advantage of it - I didn't know that the interp was in the Rabbit - I'd have to think about the implications of that...
but, yes, what you said is a possible course of action to be sure - I guess I want to use Rabbit CPU cycles for things best done by the Rabbit & PC CPU cycles...
with respect to the interp on the rabbit, I guess it depends upon whether all the i/o for your application is on the g-rex, if so then putting everything on the rabbit makes sense.
when it's all in front of me, I'll form an opinion ;)
mshaver: well, the gui compiles for Linux or doze .. I cross-compile the doze variant on Linux :)
for my app, all the IO is on the Grex, so I just go that way ..path of least resistance
its 99% steves work, I've just been bug-hunting and making mods for my plasma stuff
gotta go for a while - I'll update my G200X CVS in a bit - cross compile eh? I'll look closely at that! - too bad there's not a MODBUS output on the G-REX to make it expandable ;)
well . .theres spare stuff on there for sure
So, Steve's version IS what's on Sourceforge?
steves original code is tagged alpha_3
I loaded some stuff to head
I should commit some more stuff I guess
but not exactly many people have show interest until now :)
well, no hardware, no interest...
loaded dynamic C yet?
But, Steve hasn't gone on and developed any more code that's not on Sourceforge?
mmm, not that hes released to me .. I think hes been rafted with work
Not yet (Dyn C), I've actually got to load up Windows on a box first ;)
the latest version is VERY interesting of the FPGA
with the embedded processor
:) well better with a shorter z hight :) http://www.whipy.demon.co.uk/cncz7.jpg
that I suspect is interwovem with his "unstallable stepper" stuff
The White Heat stuff - just got the manual yesterday...
I've got to sit down and read it
AchiestDragon: that looks better .. does it feel more solid?
well, gotta go & do some work in the shop - patching & painting some doors for a rowhouse I want to sell in Baltimore...
mshaver is now known as mshaver_away
AchiestDragon: did the Grolsch help?
think i found some steppers also
I just spotted the allthread that goes under the machine ... that must help with stability a lot
£39.50 each new
7.5v at 2.5a per phase
a bit high ... but not too bad
high drop *usually* means high inductance too
and that means slow speeds
thinking 70v at 8A should drive 3 of them ok
3 * 2.5A = 7.5A so allow a bit for spare and 8A fits ok
5A for 3 drives will be mroe than enough ... infact, I bet you dotn ever pull more than 2A in normal circumastances
typically less than 1A even ..
7.5V @ 2.5A to the motor ...
70V and ~250Ma into the drive
at speed, under loadm the current draw goes up
i like to over rate powersupplys it makes them mor relayable in the long run
if i need 1A at 12v i will use a psu capable of 2A
basically, I reckon you'll typically only pull 2A in normal operation
build a 4A to 5A supply
the recommendation is to use a supply capable of 2/3rds of rated motor current .. in reallity, thats overkill for most people
farnells do a 7.5a 35-0 35-0 transformere it can be wired to give 70 - 0V out no problems
ummm .. how?
X axis motor losted steps.. 2 jobs aborted grrr..
AchiestDragon: 0-35 in series with 0-35 gives 70V ac ...
rectified thats around 100V dc
100V dc is about 30V greater than 70v ...
was planning on regulating it
dont do that
the drives are switch-mode self regulating
they prefer a normal linear supply
so 50v transformer output
25-0 + 25-0
robin_sz: what if i can turn my steppers with hands ?
Jacky^: what driver you use?
Jacky^: or 297?
right ... so that has no curent reduction do that is full torque .. so that is what torque you have ...
it have current regulator..a trimmer
powerd or unpowerd , unpowered yes , but if the driver is enabled and powered then you should get at least the holding torque as risistance
I tried any value, from 0 to 2 amp..
Jacky^: what is the recommended value for the motor?
motors should have 2.1 A /phase
90 oz in
well, turn it all the way up to 2 amp then
if is true ..
robin_sz: i'm using half winding , as we talked week ago.. it work better for me
current should be half, for what i know..
well, less torque at low speed with half winding, but more at high speeds
correct .. use same current
in theory you can use more current
(lower resistance = lower heating)
to get more torque ?
but your drive only has 2A anyway
yes, more current = more torque
i can't understand why motor lost step ..
or reduce friction
the strange thing , it seem to lost steps also in slow speed ..
check your pulse system .. it could be an electroic problem .. ground loops etc
use lower acceleration too
is there a way to know how much inch/min my machine is going ?
stopwatch and a ruler
Jacky^: sure ... the control will tell you
the gui show 27 max speed
27 ipm then
this mean 27 inch/min ?
yes, if the machine is set up in inches
no input scale need to be calculated ?
yeah, machine work in inches
so .. its 27 ipm
accell. is 2 at the moemnt
for all axis
thats 2 inches per second per second
too fast ?
so it is at max speed in 0.25seconds
try redcuing it .. see fi it helps
steve_stallings is now known as steves_logging
EMC used to have problems at low accels
the recent bugfixes might have helped with that
thanks, i will try..
ok .. oiff to the unit .. see you later
anonimasu, why's she evil? she just is.
SHE's all are ALPHA...
* logger_aj is already logging
anyone know if is possible to buy geckodrive in europe ?
there was a place in England, but not seen or heard from the guy in over a year now...
paul_c: are they full emc compatible ?
Gecko will ship to Europe, and with the US $ being pretty worthless at the moment, they would be cheaper.
I've not had any problems with the three I use.
i'm tired to play with
i will send some email to ask..
i hope 220V already exist ..
nope - 80V DC max
ah well.. better
i was mean PS included ..
No, they are just the drives - You have to supply power supply, heatsink, and wires
that's ok, nice
you have a 24V transformer ?
24-0-24 8 A
what ratings on the stepper motors ?
about 80 Volts
but i'm thinking to buy 3 nema34
Do you know the resistance ?
48V AC *sqrt(2) = 67.8V DC
2.3V * 25 = 57.75V (max)
Your power suplly might be a bit too much...
at the moemnt is about 32 V output
24 * sqrt(2) = 34V DC might be better to start with.... (less diode voltage drop)
Run the geckos at 32V and see how you get on... I don't think you would need much more than that...
but you have the option..
paul_c: the motors..
i'm not sure about steppers
these im using seem to have low torque..
datasheet say 90 oz in
i don't know if to buy only the drivers
or motors too ..

:) well finaly got the live cd to work
AchiestDragon: It is about as easy as it can be made...
bung it. boot from CD.
how much easier can it get ?
actualy it looks ok , but looks like i'm going to have alot of feature requests to file
AchiestDragon As long as they ALL fit in 2KB, you can have them.
Befire you mail the developer(s) over feature/bug reports for Live...
check to see if it is still maintained.
so what new features does the current version bdi4.2X have that this misses out
BDI-4 is not a live CD for starters...
configuration options to suport diferent paralell port pin usage ?
Well, this kinda stinks... One case I have has the room for a 24V PS and xylotex board, but not the cooling. The other case has the cooling but really limited on space.
emc2 == cvs only (afaik)
i know its not live cd
No. emc2 HEAD is not for BDI-4
AchiestDragon So HA! you can't have it! neerer neerer neerer neerer
there is always src
:) well could put it on this pc , but by the looks going to set up a machine just for it
could of used the qt gui framework would look better in kde that way
Use the Live CD to get a feel for it - Mail the user/dev lists for feature requests for EMC only.
* paul_c hands AchiestDragon the Qt development libraries F.O.C.
already got them
you do Qt programming ?
although qt4 is a bit of a pain at the moment
I thought Qt == $$$
well was starting to learn , but as kde is switching from qt3 to 4 and qt4 dosent look quite ready yet i'm sort of on hold
qt is free if your using it for gnu applications
Jymmm: *slap, slap, soggy slap"
Jymmm: my friend :P
Jymmm: i decided to buy 3 gecko
and motors too ..
what about this page ? http://www.homeshopcnc.com/page3.html
i like 640 oz/in Model # RHT34-640: $110
it seem to me a nice price
and good motor ..
NEMA34? what you driving with it?
no I mean machien wise
Jymmm: i want to build a 'small' machine 1x1 mt
for wood only
Jacky^: ah, ok.
1200 oz/in Model should be nice too ..
maybe too strong for what i need
Please email us for shipping fees for orders going outside the Continental USA. Thank you!
iv'e no credit card to use with paypal ..
i will ask
if you set up a paypal account it will let you transfer from your bank
it's scarry giving paypal full access to your bank account.
you will need to go through the verification , and it takes a week to sort out
I personally would setup a seperate bank acnt.
Jacky^ you can use a check card if you have one.
I don't know what you mean as 'check card'
i've bancomat ..
can always post them a cheque with the order printed out
Jacky^ It's like a ATM card
Jymmm: never eard here..
visa or mastercard
:( no visa..
switch / solo card
i could ask for a credit card ..
Go to the local post office and ask for an International Money Order
proably 3-4 week .. of time
or ask Jymmm to mail you a set as a gift..
if you write a cheque with the ammount in the currency thay want , you will be charged at the excange rate to your currency at the time its cashed
from postal service should be ok
AchiestDragon: The banks both ends will charge a bomb for it
postal orders then
yup - IMO.
paul_c: what you think about nema34 steppers ?
one of the reasons i got a credit card , makes buying things globlay easy
never used nema34 - 23 or proper servos
i can also afford 1200 oz/in Model
+ 30 $ difference ..
anyware in europe stock them
30 $ each
AchiestDragon: also the drivers ? O_O
I need the drivers, so ..
you need to check shiping costs , may work out cheaper to get same steppers from europe and the controls from there
don't forget import duties.
* Jacky^ sighs
It can get expensive...
shipping for the fet3 econo system form stepper world was $41 to the UK from the US and that was only about 2kg

G201 $114.00 IF PURCHASED WITHOUT A MOTOR.
$109.00IF PURCHASED WITH A MOTOR...
and the weight of the steppers
which site is that ?
Weight (kg) 3.8 for 1200 oz/in Model
they say are now stocking in larger quantities..
ouch ,, for 3 steppers (12kg including packaging ) from the uk to the usa would be £90.15 and 5 to 8 days delivery time
or £101.35 if you want it in 2 to 3 days
AchiestDragon: how much in euro ?
UK£ 101.35 = 148.642351 Euro
chepest is £68.75 but its 28 to 30 days dilivery time

i eard geckodrive made some driver for servos
No physical address... but a whois suggests Mission Hills, Ca.
working with clock-direction pins
it's true ?
G320 & G340 drivers
but you need servo motors with encoders attached.

paul_c: nice.. right prices too
$90 shipping charge to Europe.
yeah.. thats ok
i found it cheaper on shiping from hongkong than the US
especialy when the steppers are made in that region
AchiestDragon: nice ..
i want to look at MAE too
that near to me ..
the steppers will probalbay be cheeper if ordered from the manufactures there if you know the manufacturer of the steper contact them , if thay wont handle small orders thay will probalbay be able to tell you a distributer that stocks them local
and in some cases you may find thay do other types that may be sutable also
if your realy lucky you may be able to request free samples
