JT-Hardinge flat or tube?
JT-Hardinge: I have one of these LOVE IT!!! http://www.newegg.com/Product/Product.aspx?Item=N82E16824001317
All the reviews about the stand are bullshit, totally easy if you have half-a-clue (tm).
JT-Hardinge: Got it for like $239 It does 2048x1152 without needing Dual-DVI and the contrast ratio is 50,000 not 20,000.
JT-Hardinge: FULL two page layout at that res.
that's a great monitor, isn't it
Yeah it is - great price too
it looks like that resolution never caught on though (at least not at NewEgg) - they only had one Acer (at that res) in stock last week
that's the monitor I use on the camera array, so I have the 7-desktop 3D rotation thing going with it
oh. the Acer is out of stock too
it's the only active item at that res, and it's a $450 27" one
I waited a LONG LONG time to get an LCD becasue I wanted the 2048 (two page layout)
yeah. I really like that monitor. the color seems very good, the swivel stand is nice, and it's a good size and price
I should have bought a fwe more
LCDs are a thing of the past now aren't they?
isn't the new thing LED?
SWPadnos: Looks like it's been discontinued http://www.superwarehouse.com/Samsung_2343BWX_23_Widescreen_LCD_Monitor/2343BWX/p/1556488
that's LED backlighting of LCD panels, not real LED displays
CCFL and EL backlighting are no longer
there's only one LED monitor that I know of (that's actually for sale), and it's a Sony TV that's something like 11" and $2700
OLED that is
MarkusBec is now known as MarkusBec_away
eventually, OLED may replace LCD, but it'll be a while before it gets inexpensive enough for that
well teh LCDs sure dropped in price pretty fast
Jymmm, shows discontinued there as well :)
yeah, 22" or so have been sub-$200 for a couple of years
depending on other features, that is
I bought one of these as a cheap HD TV for my bedroom: http://www.newegg.com/Product/Product.aspx?Item=N82E16824254043&cm_re=hanns_g_monitor-_-24-254-043-_-Product
how's the image wuality?
(if you've hooked it up to a PC)
only thing that pisses me off about it is it bleeds through on the edges on a black screen other than that its OK
ok, so the bezel doesn't "seal" the edges?
nah i only use it to watch TV on
I guess its like a halo of light around the edges
that looks like a reasonable monitor for my mother
if there is anything on the screen you don't notice it
but before i turn the set top boxo n and its black I can see it
ok. she'd have the screen off if there's nothing on it ;)
other than that its HD I wanted a smallish one so I didn't knock it over atthe foot of my bed
but its not as vivid as the Samsung I have downstairs and it doesn't upscale either
well if it does i never figured out how
monitors without HDMI inputs rarely do that well
and ones with HDMI it's a crapshoot
this one has HDMI
I didn't see it listed in the NewEgg description
and thats all I use on it from the fios TV box
oh wait, I was looking at the wrong description
I donno maybe this isn't exactly the model I have then because mine has HDMI
if only I could get fiber here
yeah its amazing i can get it
it would be easier in Korea
only reason is they said they were going to wire the whole exchange I'm in and they finally did it
verizon guy I said they're not expanding at all it costs them too much
its just not worth laying the cable now
I sorta felt bad because the drop they had to run to me was over 900 feet
but now that its done I don't feel so bad about it really
that's a heck of a cable ;)
yeah I got a pretty long driveway
and they had to come from the far side of the property for some odd reason too
that at least they attached to some old phone cables on the pole
but down my driveway they buried it
for a cheap TV to fall asleep to I guess the Hanns G is OK
half the time I'm watchng it with my eyes closed anyways so I guess the picture is good enough for that :)
I bet today you can find better for cheaper though
oh the other annoying thing about it is no remote control but i use the set top box remote
one more thing the speakers in it are a joke
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2010-03-23.txt
forgot about that I have it hooked to a 5.1 system
monitor speakers are rarely useful
speaking of which, I should go upstairs and watch a movie. see you

PCW: hello did you compile the bitfile yet?
SWPadnos_ is now known as SWPadnos
pcw_home: did you compile the bitfile?
You might need 2.4 pre or whatever its called since the bitfile uses a rev3 IDROM
how can I get ahold of it?
did you put it in the cvs?
its on our website (with 5M glob of 7I43 stuff)
(its not in CVS)

how do you still make the axis able to have a position loop?
hmm, the steppers get internal vibrations so they stall, wtf can that be due to ?
MarkusBec_away is now known as MarkusBec
it sounds like a bushing that gets tightish so that it gives a squeeking sound :/
gah this sucks, if i wanna upgrade my stepper board this board can take 36V the other they have can only take 32V
and ive got a 36V supply :P
hm.. isnt ti resonance that causes that to happen
hmm, vibrations due to jerking of the motor?
but it sounds like something is very wrong like i got dirt in there or its starting to "sease up" ?
like you get from a computer fan when its giving up
sure if it just stalled .. but the sounds it makes makes me a bit nervouse ive managed to destroy the motors somehow :)
and it stalls out at many places, like at 700 mm/min - 1200mm/min it wants to stall both here and there :/
at 1200 i can make it out to be 32000 steps/s
can that be right ? :)
leadscrew pitch of 2mm
MrSunshine: things like this can only be debugged piece-wise
take the motor from the machine
check how it works at all speed ranges
put on the machine, don't connect the coupling, test again
move the machine by hand see if you feel rough spots
alex_joni, well its when its free it stalls out like that
goes a bit better when its on the machine
are stepper motors lubable in someway or should i stay away from that? :)
what kind of drivers are you using?
sounds like midbase resonance to me
Stepper Driver 1.8A 12-36v 4-Axis, TA8435 based
think they have a bit low chopping frequencies or something also, motors scream like hell when idle :)
what kind of microstepping does it have?
1/8 it looks like
i thought it was 1/16
there are a few modes possible but I'm having trouble understanding the data sheet well enough to say how to select them
"Sinusoidal micro step operation is accomplished only a clock signal inputting by means of built-in hard ware."
on my driver board i just move a couple of switches to select modes
do those control M1,M2 signals?
dont know i havent built the board :)
I'd try M1=high, M2=low for 8 microsteps sinusoidal
it also has straight half stepping
according to datasheet on the driver its off off for 1/8 steps
[14:13:15] <MrSunshine> http://www.brundin.biz/redirect.php?action=url&goto=www.brundin.biz%2Fimages%2Fdatasheets%2F4-axisdriverboardTA.pdf
oh your board's datasheet? I was looking at the driver chip's.
cradek, aye my boards datasheet =)
for me, that pdf is blank except for some useless screen shots of some other control software
cradek, at the beginning there is pictures of the board and info about connectors etc for me
I get scolded that I need to download some font. ;)
The resolution setup
S2/S1 ON/ON non resolution ON/OFF 1/2 OFF/ON 1/4 OFF/OFF 1/8
can chopping frequency etc make motors stall out also at strange stepping frequencies? :)
Jymmm: that monitor is not available and is way too big for my lathe :)
it would be a nice one for down in the beer cave
there ya go
now the question is how do I get the 2.4 pre
you can get it from git, or there are packages
cradek: types fast :)
hm, where can I find that packages?
[14:43:24] <JT-Work> http://emc2-buildbot.colorado.edu/~buildmaster/
now the question is how I get the 7i43 working..
where do I put the firmware for the 7i43?
if you had a previous version of EMC2 installed, there should already be firmware for you though, and maybe /lib/firmware/hm2 is a link to another directory
I see the fimrware in the package manager too
you should be able to use the old firmware, I believe. I don't think there are any changes to its functionality
ocw said I might need to use the new one to make use of the bitfile he made
(if I got him right)
ok, that could be
wait, he made specific firmware for you?
in other words, did he send you a bitfile?
he fixed the pin file for the 7i43
You may have to shorten the bitfile name. theres a path length limitation
what steps do I have to take to get the card working at all?(first things first)
I get some stuff like "fauled to reset fpga"
copy the new firmware into the same directory as the old firmware resides, and change the name of the firmware in your ini/HAL files
oh. then pcw will have to help :)
better question is is there docs on what I need to get i tworking
do I need aux power for the boards also?
Failed to reset FPGA can mean a lot of things, either power supply or EPP communication related
has the 7i43 ever worked on this computer?
no it's brand new
If this is a motherboard parallel port, you shoudl make sure that ist set to EPP mode in the BIOS
let me check
epp mode should be what?
1.7 or 1.9
found it http://www.linuxcnc.org/docview/html//man/man9/hm2_7i43.9.html
hm, I have no jumper for usbpwe
as it should be
will my 7i43 load with the wrong bitfile?
to see if my communication works?
it will load any 7i43 200K bitfile
so, I should be able to just connect it to the port and try loading it with a file?
You should be able to just connect it, supply 5V power, and run the demo config
ah.. so I need aux 5v power too.. that clears it up
well.. the parport doesn't have 5V
The 7i43 needs 5V power...
that's why it's best to hook up the usb cable too (simplest solution)
but I were stupid and bought without usb...
pcw_home: yeah, I know.. parport having 5V on it would have saved a LOOOT of issues in the last few years
anonimasu: then you need to connect 5V to it somehow
old usb mouse cable works too ;)
just cut it, use the 5V wires, connect to 5V terminals on the 7i43
PCW_ is now known as PCW
I'll wire up a 5v adapter :) later for now I need to get the powersupply
or take a usb cable and steal the 5v..
or take some from your power supply!. 7805 will do the trick.
Beware of leakage from separate power supplies. make sure the PC ground and power supply ground are connected together
somewhere other tnan just the parallel cable
i wouldnt connect any parallel ground with powersupply ground. the signal should never interact with power supply.
The problem is if you have a floating supply and hot-plug the parallel connection you may damage the PC or 7I43
the power supply must have a common ground with the PC (this can be through the parallel cable, but then hot plugging can cause damage)
Using the PCs 5V is probably safest
what is the need to hot plug?
No need but people seem to do it...
* skunkworks hugs his pci card
where does it plug into? pci slot?
I've learned this from using cell phone chargers as 5V aux supplies, 5V 1A ones are common but
the outputs float at about 60=80VAC since their RFI filters return to the power line.
They work fine for running things like a 7I43, but dont hot plug the parallel connection
because if the first pin that happens to connect is a signal instead of ground pin, you lose....
skunkworks: what is that board for?
skunkworks: you've got a good assortment of OPTO 22 racks...
ebay is awesome ;)
that it is
I don't know if you saw that.. worked great
hm so what about using a usb cable.. and just stealing the power... lines
elmo40: this build is going to use 2 5i20s
mesa pci 72 i/o boards
anonimasu: thats a good solution. If the 7I43 has the USB stuff, its best to cut the data wires in the cable
skunkworks: get that motor all cleaned up? i only see 'before' pictures
well, for now my lab supply will work
elmo40: I don't think I have a finished picture http://electronicsam.com/images/KandT/conversion/servo/commutator.JPG
( the 7I43 will use about 150 mA of your 450 mA USB power leaving ~300 mA for your
daughtercards so don't try to power up any ancient incandescent lamp encoders or such)
it works kindof but emc dosent start
PCW_ is now known as PCW
anonimasu: make sure you have the firmware package.
hmm got the motors to run a little more nicley tweaking the step time etc values
but still wants to stall out over about 600 mm/min
PCW_ is now known as PCW
hell they even stall out without load on them at higher speeds, if im not holding the motor firmly so i guess its a resonance issue
there enough current pushing through them?

oh lovely OneCNC just ruined a part I've been working on since Friday :/
JT-Work Did you help it or did it ruin it all by itself?
when is that getting converted to emc/
I didn't double check what it picked with my print when I picked a pocket depth
it picked some hidden feature below what I thought I had picked
so the pocket was too deep
at least no blood letting occurred during the process
I'll bet a few bad words were issued...
no, I refrained from that as it was as much my fault for not checking as I know OneCNC is flaky like that
Wheres the "Do What I Mean: interface when you need it
yea, they don't have one and I'm spoiled by Solidworks 2010 as it almost has that LOL
and that part has a 0.125" hole through 2.5" of 1018 and needs to be straight :) and that is fun to do
if you can avoid it, never work with 17-4 PH
thats long skinny hole to keep straight
yea, a parabolic drill helps a lot

Jt-Work; it needs to go deeper than a c-drill, it will help start it straight. even a c-drill can walk when the depth is deep 2 1/2" is a LONG destant for an 1/8" drill
piasdom: what is a c-drill?
Jt-Work; this always works for my....and the drill needs to be equal on both sieds of the taper
centerdrill....is that a spotting bit ?
no a center drill is not a spotting bit but sometimes confused for one
never heard of it...thought it was thge same
totally different function for each
witch is the best to use for drilliing with a mill tool
do you sharpen your own drill bits ?
[18:32:47] <JT-Work> http://www.lakeshorecarbide.com/singleendcarbidespotdrills.aspx
the 120° are for 118° and 135° bits
SEALIVE: between what choices
i can those drill bit
but even a c-drill will walk if your drill bit is sharpened unevenly
can = call
I never use a center drill for spotting
i normaly use a high speed VHM drill to cut of the center 1nch deep for milling 15mm holes with a 14mm 7flute tool co8
If I really want something in the lathe centered I use a spotting bit then a center drill for my live center
all i ever use....one touch is all i need
i go thru in one shot at 8000RPM and 345mm/min
16Bar of cooliing presure
how big is the spotting bit you're using ?
how big is the flat tip
if there is one
[18:38:18] <frallzor> http://pici.se/p/large/IFcydmXZQ/ http://pici.se/?p_large/iPdPEjsDK
I'd have to get my jewelers loop out to see LOL
frallzor: nice :)
made a vid too with me moving it :P
but you need more light
if it is always walking....the bit may be sharpened unevenly or too old :)
cant do better atm :P getting better light out there
piasdom: I only use fresh sharp new spotting bits :)
get you loop out and look at the tip
JT-Work; try going deeper with the spot bit then
the drill bit need a better start the a spot...i usually go deep enough so the taper of the drill bit is in the hole before it starts cutting
looks to be 0.020 wide flat
and the tip of the drill ?
I don't have any trouble drilling the hole :?
if u use VHM price is not more then 1/3+ of HSSTIAN vyou can go thru
i thought you were having trouble getting it to go straight
that's the only reason i started this :)
my trouble was OneCNC used an incorrect pocket depth and ruined my part which had a long skinny hole as one of the features
I can keep the hole location within 0.001 from start to finish :) after all the practice I've had making this part
did the programm or the mashine fail
then i misunderstood the problem...
the mesa cards of mine works

Maybe a little tricky to trace from the .PIN file to the 7I47 I/O sine the pin file only gives 50 pin cable pin-out
ok wars down for some minutes now up and running from germany !
so I need to guess what the I/O is on the 7i47
Well the 7I47 manual in conjunction with the .PIN file should be enough info
dmesg will also help, since hostmot2 prints the pinout there
It would be nice if the pin file generator had a daughterboard option

thanks, i'm really satisfied with it :)
JT-Work: Thanks! last one with this trouble was in Australia and they just re-flashed it rather than sending it back so I never could figure what happened to it
apart from the 5mm steel sheet top that could have been a little larger, but that was the largest piece i could find :/
I never could get my floppy drive to work on that computer and was so busy with the Hardinge it was the best way :)
Thanks again and sorry for the trouble, will send replacement asap
ok, no problem... how did the goat roping circus go Sunday?
PCW: yeah with the old emc
it looks like this install dosent have the modules includede
I suppose I should up the voltage before I give up on these motors. 12V atm
12V is unusually low.
But it depends on whether you lack speed or torque.
Z won't raise anymore
More volts won't give you any more torque at low speed, just higher torque at high speed.
Will it rise at a lower speed?
plan B, turn up the current
no even at low speed it won't lift
Do you plan on selling the motors?
no, they cost me 10q for 4
So turn up the current until they either work, or smoke comes out.

MattyMatt if your over running it like that I'd suggest doing a bunch of rapid short Z's and make sure it doesn't over heat
machine a heatsink for yourself
the motor casing is barely warm
sounds good then just make sure it doesn't get over ~60-80C
temp sensors inside would be nice, between each pair of coils
alot of magnets get screwed at about that temp
I think they are soft iron, not hybrids
hmm I've got 3Gb of download left and a few hours to use it
they are the size of modern 2A motors, anyway
if they are steppers they will have magnets,
certainly no Nb magnets
especially at that low current level
ey theres a thought, if you wanted more torque out of a stepper system, whack NIB magnets into it, it might chop down the top speed some but still, pretty cheap
Valen, download an Ubuntu 10.04 ISO
beta 1 is out
lol thats probably unmetered for me
my ISP has its own sourceforge mirror and most of the linuxes
and all downloads from there aren't counted
oh. well in that case I don't know :)
lol yep there they are
also means all my linux needs are taken care of at line speeds ;->
if my Z motor hasn't melted in a week or two, I'll turn up the current on the table too
I really like them as an ISP ;->
SWPadnos anything good in 10.04?
later Gnome and some other stuff of course, faster bootup, later kernel ...
yeah but thats not "cool" or nifty like upstart and ext4
faster boot ay
mine already starts faster than the bios
ie bios time is > than boot
though i am running off a SSD with a quad core
that sounds like you need a bios upgrade
I just put a SSD in my Mac
how recent is your motherboard?
man those things are sweet :)
under a year
does it have SATA3 (SATA 6 Gb/s)
this bios seems to take a while to detect IDE stuff, ~8-10 seconds or so
no only sata 2
Valen: you're an aussie?
the SSD maxes out at 180mbyte/sec anyway so sata 2 is enough
there's a new SSD that's blazingly fast - something like 360 MB/sec random reads, and writes not too far behind
[21:36:07] <MattyMatt> http://www.coreboot.org/Welcome_to_coreboot
it can probably attach to a SATA II port, and would be limited by that channel
I want one of the ones that drops in a PCI Express slot
probably a bazillion dollars though
the PCIe ones are waaaaay too expensive
like $1000 for 250GB
and as reliable as M4 to very have viruses
yeah I'd do that but 99% it wont support my mbo
yeah, like could be driving a new car instead expensive
the SATA3 ones are also expensive, like $450/128GB or $750/256GB
actually the pci-e ones are a reasonoble price
compared to sata of the same size
thats still on par I think SWPadnos
there's a 1TB PCIe "drive" that's $3800, but has ~800MB/sec reads
Jymmm: whats wrong with being an aussie?
that would be nice
2/3rds of what I paid for my shiny red car but still
Valen: too many thngs to list =) lol
the SATA3 drive is fast. "boots Windows 7 in under 10 seconds" :)
Valen: Nah, was just making sure I got your ISP correctly
Valen: Yeah, I know.
thats odd, I figured freenode would hide the ip address
Valen: It would, if you had a cloak AND logged in
I would also need to care
most irc networks mask it by default is all
no, they don't.
at the moment I know I'm safe because as soon as somebody tries to hack me my modem will overheat and die making me safe
or else DCC wouldn't work.
security thru thermal breakdown.... that's a new one.
my understanding was the DCC request went through the normal IRC network and its only if you responded it gave out the address?
my mbo isn't on the coreboot sire
good evening at all. please have a problem with call file fuction type o<myfile> call. some people can help me ?
motioncontrol: Have you seen http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?SubProgramFiles
yea what you got?
[21:57:13] <JT-Hardinge> http://www.linuxcnc.org/docview/html//gcode_main.html#r3_7
andypugh, thanks i read it. i have execute some prove , but not fuction.i read doc thanks
JT-Hardinge, yes i have prove your doc , but not is ok
The main thing seems to be that the called file needs to contain a sub with the same name or number as the filename
elmo40, hmm, dont know realy the motors wants 2A and the driver gives max 1.8A if im not mistaking, might be a problem ? :)
motioncontrol: what error do you have?
I wonder how coreboot would help latency on one of those atom boards perhaps
JT-Hardinge, not execution the sub , the program stop at m2. i append the image one moment
i want a 4A driver so i can parallel connect the motors ... sigh :/
solder some more chips on she'll be right
im starting to think gecko soon
but they are quite expensive
this link for my example :http://imagebin.ca/view/XryBUnI.html
prova1 is the principal program
does anyone run servo's and steppers in the same setup?
I'm hoping to mikegg
X-Y servos and Z stepper for example
we have xyz servo and making A a "stepper"
umm not quite ;->
[22:04:14] <Valen> http://www.youtube.com/watch?v=g2N910jNOnE
ough would need 81V to drive the motor fully at 6.4mH windings :/
according to gecko
its actually a servo motor but using it as a rotary I'm thinking feeding it as a stepper (the controller can handle that as an input) is probably easier
JT-Hardinge, this is the link http://imagebin.ca/view/XryBUnI.html
motioncontrol: looks like some syntax errors
JT-Hardinge, the syntax error why ?
proval not proval.ngc
JT-Hardinge, i prove
i have correct, but not read the sub.
i have correct the sub :o<prova1> sub
g0 x0 y0 z5
the axis not go at g0 x0 y0 z5
JT-Hardinge, have some thing for this problem ?
ok I'm back and hands are clean so I can type
are you calling a separate file or a sub in the same file
JT-Hardinge, i call a separate file subprogram not subroutine
Poll: What is everyone's favorite DVD writable media?
your subprogram file is prova1.ngc?
pfred1: the closest one to my hand when I need one
JT-Hardinge so low price gets it then?
I don't buy them much so the last pack of 50 is still around
yes i have i main progam prova.ngc, and a subprogram prova1.ngc
subprogram line one should be :
same for endsub
like manual shows almost clear :/
Sweet! turret moves nice and smart and the air compressor has not kicked on yet
so no leaks in that part :)
JT-Hardinge, ok thanks now is ok, have syntax error. more thanks
I have so many new parts I don't know which end to work on :)
Cocoa has been waiting to take me for a walk in the woods...
skunkworks sounds like a rough sex in the park episode to me!
are the gecko drives worth the money? :)
MrSunshine why whats cheaper?
pfred1, stupid drivers that i bought before :P
i get 4 axis for the price of 1 axis gecko :)
MrSunshine I saw an ad the otehr day for a gecko 3 drive system that you plugged your cable directly into
but they are 1.8A 36V compared to 7A 80V :P
maybe it was 4 axis I don't remember 504 maybe?
i figured i might buy myself some geckos when i get money
mariss seems to make some bad assed drives
will set me back like half the price ive payed so far for the whole mill but hell :)
MrSunshine what kind of lead screws do you have?
i still have the driver that i bought before, can buy some smaller motors for it and build myself a pcb router/driller :)
pfred1, acme or whatever they are called, trapetzoids
yeah lots seem to skimp on the leads ball screws are 90% efficient as opposed to 40% of acme
so you'd more than double your performance just dropping new leads in
pfred1, its the default on the mill its a sieg X1 mill im converting :)
only coreboot mobo I've got is a dead Thinkpad T23
yeah it is common to change over to ball screw on mills
pfred1, i will as soon as i can get it all running as im even having problems running the motors at high speeds without them mounted on the mill i figure something is wrong on the way to the motor :)
any good commercial CNC conversion changes out the leads
like that i have to run the motors in bipolar serial connection insted of parallel
pfred1, commercial ? its not like im going to sell them :P
best performance is parallel but your drivers can't handle that right?
MrSunshine you can still compare what yo udo to what professionals do
pfred1, 1.8A max, motors are rated 2A 4V in serial mode
and you say unloaded they don't run right?
LOADS of vibrations so they stall out themselfs
unless i hold them realy firmly then they can run at higher speeds
I had that problem myself until I optically isolated my control signals
pfred1, they are opto isolated on the driver board
but they run OK loaded?
pfred1, run better loaded then unloaded just holding them loosly
yeah running right they should run fine free
PCW_ is now known as PCW
pfred1, yeah i figured they should =)
could one coil inverted cause that?
have you checked their current draw?
MrSunshine yeah like MattyMatt said are you sure you have the motors phased properly?
pfred1, well connected them according to the place i bought them, as they specify the cables and what winding they should go to
so colors goes to the right holes in the driver
pfred1, nop, how can i do that reliably ? :)
just put an ammeter in line with the driver power
and test it free and loaded and see what it does
loaded amps should rise a little
I use an analog to test mine its easier to watch the needle
k, have to check that tomorrow :)
pfred1. Lunokhod2 drove 37km. that's the record for Opportunity to beat
and gonna double check the cables also :)
I think on Jones page he explains motor phasing
[22:42:33] <pfred1> http://www.cs.uiowa.edu/~jones/step/types.html
MrSunshine taking a wild guess it almost sounds like your motors are suffering from resonance
and just holding them makes them stop resonating so mush
MrSunshine this looks like a pretty good page: http://www.piclist.com/techref/io/stepper/wires.htm
MrSunshine check out the Bill Krause method about halfway into the page
* frallzor needs to get rods for his e-chain rack tomorrow
frallzor: what are you building?
JT-Hardinge frallzor is making eBling!
JT-Hardinge a mill =)
it's big :)
can 6x M6 in 2mm material hold like 1kg with forces from the side
not just straight along the screws
frallzor whats that in inches?
* pfred1 knows a KG is about 2.2 pounds
2 threads will be in the material
heck almost a quarter of an inch can hold up a couple of pounds no sweat
if you really doubt it tap a piece of scrap and wail on it I bet it'd hold though
ah material steel or aluminum?
yeah i say go for it
wont be any more force to it than its own weight practially
just the e-chain
I bet it'd hold over 100 kilos
frallzor just don't strip it out in the process to prove me wrong OK?
I will :P;)
yes let me qualify done right I bet it'd hold over 100 kilos
frallzor sounds to me like you should be using sheet metal screws or something for the application though
Sweet! one more thing crossed off the list... one day the only thing left will be to make parts
my list is so long I don't get too excited if I cross something off of it really
* pfred1 did install a parallel port card today though ...
* frallzor has reached a few milstones, every step now is exciting
MrSunshine: Where did you get your motors from? I bought some 8-wire motors and the data sheet was wrong...
andypugh yeah i like this one guys test it sounds rather exhaustive and definitive to me
my list is so short I can see the light at the end of the tunnel and I'm pretty sure it is not the train coming :)
andypugh the Bill Krause says: about halfway down this page: http://www.piclist.com/techref/io/stepper/wires.htm
I went through this myself....
Wire the pairs in series. If you have the ends wrong then you get current and no torque...
It doesn't matter is one pair is switched, you just end up with a reversed motor.
Once you have identified the ends (using a bench power supply, not a stepper driver) you can wire in parallel.
he can't his driver can't handle the current
it's iffy that it runs his motor in series
I was speaking in general terms...
18:35 < MrSunshine> pfred1, 1.8A max, motors are rated 2A 4V in serial mode
so he's 200 ma shy of really running his motors in series even
still as long as he didn't smoke his driver I'd think it'd run his motor correctly
just not full power
but series is high torque low speed right?
Aye, I was just saying that the way to test is in series, even if you want to run in parallel. And you should use a generic PSU not the driver for the testing too, some drivers hate being disconnected powered up.
It actually seems to make very little difference. I have one of my bigger steppers on a 7A driver in parallel and one on a 3.5A driver in series, and they run pretty much the same.
I always heard parallel was the best performance
You have a higher voltage ratio and a lower inductance in Parallel, so should get more speed, but I have not noticed that being a huge difference. And the driver cost is way higher.
when i built my motor driver i had this strange deal where it'd run much better with less current
motor is rated at 2A but I find it operates most smoothly at half that
and its really finicky about it too
That seems odd. I wonder if the driver is sending a weird pulse shape?
andypugh, jb cnc .. www.brundin.biz i think it is .. tho its swedish :)
like a little too much or a little too little really hurts how it runs
[23:29:13] <MrSunshine> http://www.brundin.biz/images/extra/STM76-185-wire-serial.jpg
there is the wiring diagram
MrSunshine don't tell me you're running in full step mode
MrSunshine Ok good
because full step is sort of oddball
The "Expired" 716K one?
MrSunshine if it were me I'd still work through phasing the motor just to make absolutely sure everything is as it should be
MrSunshine BTW Sweedish is a lot like english
pfred1, the wiring diagram is in english :)
MrSunshine I always thought sweedish was more like hu durper duper du!
tho the page is in swedish :P
[23:33:12] <MrSunshine> http://www.brundin.biz/product_info.php?products_id=3
It is, I found that in Sweden. Lots of the words are the same, just generally the less "polite" version. Like "drag" means "pull" but in english you tend to only drag things that don't want to be pulled...
MrSunshine now thats a recipie for sweedish meatballs if ever i saw one!
how in the hell do countries operate with runes for their language?
I had a motor with exactly the same wire colours, the data sheet was wrong...
MrSunshine yeah man do the right thing ring it all out!
MrSunshine unloaded it should run and you can't even hear it
it's a small step for mankind with 5 tubbies of parts emptied and 3 more covers back in place on the Hardinge
but one giant leap for me :)
JT-Hardinge no its one small step for man one giant leap for mankind
I forget what he was supposed to say he mucked it up though
I guess if I flew to the Moon in a recycled TV dinner tray I'd be a little at a loss for words myself htough
MrSunshine: It doesn't need to be a complex test. Do you have some sort of current-limited power supply?
when they built the LEM they had to put pans on the floor because if you dropped a screwdriver it'd have gone right through it!
andypugh, nop i dont :/
andypugh a flashlight battery
Just twist together the common ends of each pair, then apply current to the other ends and see if you get holding torque. Then switch the polarity and see if it jumps a step and gives torque again.
A battery is a rather bad idea, as they are not at all current limited.
MrSunshine just work through the instruacions on this page: http://www.piclist.com/techref/io/stepper/wires.htm
Ah, no, ignore that last bit, a 1.5V battery will be perfectly safe.
andypugh sure htey are a standard D cell can't put out more than 1500 ma
and thats on a dead short!
Are you sure about that?
That seems to indicate that with a dead short it would take over an hour to discharge and that seems unlikely.
then put a light bulb in line with it
but I think it'd be completely safe to do
The motor is 4V steady-state to the 1.5V battery will be perfectly fine.
the last bench supply I built is variable voltage and current
its pretty cool
but to test out a stepper motor I'd still grab a dry cell
my fav benchtop power supply is the PS from a PC
the plug that goes to the MB has one green wire
mikegg how do you adjust the voltage?
ground it to the case and bam, you have 12 and 5 VDC
mikegg lrn 2 linear
mikegg: Not the PC power supply I bought, it would sulk if there wasn't the right load on every voltage.
so - is there a way to find the closest place a movie is playing? sort of a revearse movie lookup?
yeah i thought PC supplies had to be loaded 10% for accurate regulation?
skunkworks I think I've see that sort of a site on the net
I will keep looking
mikegg this is the supply I built: http://hmin.tripod.com/als/andysm/drawings/supplies/ps2-30v.gif
dead simple works a treat
I never know how to read those things
5k6 != 5006 ohms
they use the K as a decimal because dots get lost in crappy copies
Read the prefix as a decimal point
Like a 28k6 modem
here's my supply like that schematic: http://img713.imageshack.us/img713/2244/pict0579s.jpg
which components need a heat sink?
mikegg the power output transistors
yeah i used some NEC jobbies I pulled out of a mini desk computer
any NPN power transistors work
i love canibalism
its basically al inear amplifier that plays one tune the juice song
and in current limit mode its cool once you reach current limit it just keeps backing off the voltage
so you can never exceed the set limit
how do you switch modes?
just a potentiemeter
what did you gut the cap from
turn it up more current down less
oh i scrap everything
old TVs stereos computers you name it
BTW that high current diode in there for protection yo ucan get them out of PC switching supplues as back to back diode arrays
every supply has one
then just use one half of it and you're in
here's me load testing that supply: http://img196.imageshack.us/img196/6414/pict0576h.jpg
each bulb is eating like 2 amps
I wonder what this lot is worth?
