i run a 20mm indexable endmill in my 200W servo spindle, machine rigidity limits usable depth of cut alot but the motor doesn't seem to mind the load
btw is it ok to update emc2 in linux when installed via live-cd?
Z limit switch set to in-04-not (switch closes on limit). Z Home switch set to in-05 (switch opens on contact with home). if home switch is on the home rail i get a joint 2 on limit error? what have i set wrong
archivist: DaViruz: i founf i have a new 10W 25krpm spindle motor with key type chuck , it sez 20mm dia max tool so, right on! :)
its brushed, and 110ac ,how can i control the speed?
10W? i hope that's a typo :)
chuck opens to 6mm shank
20mm dia sounds like much at 25krpm, not much torque at 210W
ah, brushed ac = 'universal' motor, lotsa speed controller, but lookin for computer controlled, even if open loop
and 20mm tool with 6mm shank? :/
yep, they're bragging, i consider the 'specs' as fringe limits
tom3p: did you end up ordering those little servos?
yep, they're really nice, but my 5i30 is back in chicago, i'm stock in cincinnati
I orders a few also - they are currently out of stock but they think they have some more.
(mine are on their way)
i found lots of universal motor speed controllers, but the control is a pot in an AC circuit. dunno how to make that computer controllable
skunkworks: you'll lik ethem, i've used pittmans before ( replaced Takagama's ... much easier to get and loads cheaper )
How do you change the units on your linear encoder. Mine is reading mor then half of what it should.
jimbo655: for a ttl encoder, i dont know of a way. for sinusoidal, its a matter of counting angles on the sinus... and i believe Jon Elson has created a gizmo that is programmable output ( like more or less than the sinus period )
I have converted to ttl already. I am looking to change the way that EMC2 reads the encoder to get the correct numbers?
It wold be no different then an encoder on your servo motor at 200 clicks per .200. I am looking for the value to change to make the correction.
the value that you tell emc is based on what 1 encoder count is 'worth' on your axis ( eg: 1 count is .000127689 " or .123 degrees" )
the value does not have to be nice, it just has to be true
and there's 4 counts per pulse ( a 500 ppr encoder yields 2000 counts after something called 'quadrature' )
this looks handy for digital control of a universal motor http://www.zilog.com/docs/z8encorexp/appnotes/an0235.pdf
its meant to be embedded, but the idea might be generalized enuf to let the mesa control it, given some i/f
hmm, pwm control, uses a magnetic encoder (8 pol pairs per rev) http://www.eu.necel.com/_pdf/U17101EE1V0AN00.PDF
ok, you need to know the zero crossing event on the ac line, and have rpm feedback from the universal motor, heres another http://www.divinecirkits.com/projects/Embed/speed_PID_Alg.DOC
( dontya love docs in DOC format? hint.. export to pdf using OpenOffice )
sorry about the crappy picture - my somewhat less crappy camera is dead http://imagebin.ca/img/Hrz6iD.jpg
skunkworks, very nice.... I see it is getting filled already
heh - just cars and construction material
Now for the fun stuff.... I am tryng to get the homing sequece working. After it locates the limit it moves the wrong way at high speed... not good. I am not naking heads or tails out of the varius HOME values in the ini file.
Does anyone know why stepgen_maxvel was removed from all the config files during 2.3 development ?
it shouldn't be necessary for most machines
like any trivkins ones I think
SWPadnos: true, but it was also removed from the non-trivkins configs apparently
oh. that may have been a bad idea, but I'm not sure if it should even be necessary there
SWPadnos: at least some of them
SWPadnos: at least it's very important for the thc configs, I'll recommit it for the plasma stuff
I don't know if it's just covering up another issue
with the automatic Z movement it's the stepgen_maxvel that controls the velocity
so it actually serves a purpose where the z axis velocity is less than the max vel for the other axis
and velocity is not determined by the trajectory
the Z vel conmtributed by the THC doesn't enter into the TRAJ calculations
-m (again :) )
SWPadnos: exactly so it's determined directly by maxvel_stepgen since vaxvel isn't consulted
so the relation between X Y and Z will be the same as far as TRAJ is concerned
SWPadnos: YEAH BABEEE http://en.wikipedia.org/wiki/THC
right, if you're using HAL to add vel to a stepgen, you need to limit it in HAL as well
Jymmm, I don't even need to look :)
Saw that today, couldn't resist sharing
Reminds me, a while back I gave a talk on mission critical linux systems and I used emc as an example of an OSS project where bugs are not tolerated, when I explained that bugs mean several hundred pounds of steel crashing into each other and bits flying off it left an impression
that is a pretty good example
show the video of that guy with the probe?
dunno, what video is that?
heh heh "automatic probing"
i'm looking for it now but i think the guy might have taken it down
automatic probing sounds like something aliens might use for unmanned space flight
Were back. I have movement on the Z joint. I can jog up and down some I seem to have a problem when i hit my home switch. EmC treats it as a limit. not sure how t correct
yeah the automatic probe one is gone
jimbo655: do you have separate limit switches?
in HAL, you need to connect the input pins for the limit switches to EMC's limit inputs, and the input pin for the home switch to EMC's home input
Dallur: are you using a MP1000 for THC?
Question: with linear scales, is the "reset" pin a pulse as you go past the point or is it a "on for the last inch" type thing
at least some scale indexes are a pulse every so often
so you use them in combination with a home switch, just like a regular encoder
I have Zhome defined as Linksp in-05 and for the limit i use NET limit-z in-04-not
(I am not an expert)
hrm how would I go about looking for this pulse, its all wired up into a working EMC (IE i have the DRO side of things working) but I am yet to see anything on that line
use halscope to trigger on it
jimbo655: I don't know what that means. the best way to see what you have is to do "halcmd show sig" while EMC2 is running, that will list all the signals that you have defined
assuming i have no idea how to do that, how would i do that lol?
if you pastebin the result, others can see too
I tried using halscope but the problem is I don't know if the limit is that I don't know what i'm doing or if theres no signal
Valen: back up a second. what's it hooked to?
mesa 7i40 + 5i23
ok you don't see it directly then. you hook it to the encoder index input.
it's the encoder hardware's job to handle the index pulse.
I was hoping to use it as a home switch
you can set the encoder's index-enable pin true, then when it sees an index it will reset the position. homing does this for you.
How would i test this? keeping in mind that there are no motors on this conversion yet ;->
Valen: you can home on only index. you will have to manually position the machine between two particular pulses and then homing will seek out the correct pulse.
I was hoping to be able to see the pulse on something so i could tell if it was the kind that only put a pulse out at one end, or at intervals or not at all
you will only be able to "see" it indirectly by setting index-enable, then moving the scale past the pulse, and seeing the position reset.
none of the halscope pins would be able to see it?
or, I guess you could physically wire it to a digital input also, and move very slowly, and you will see it
also if it is a periodic pulse and it resets the co-ordinates wouldn't that be a really bad thing?
homing deals with that for you. that's how homing works.
it's sure true that you don't want to reset the position while emc doesn't expect it
so index enable only resets cordinates during homing?
the encoder's index-enable pin is hooked to the motion controller, which uses it at the right time (part of homing)
I'll find out how to turn that on and give it a try
I need to start mucking with ini and hal files now anyway
homing docs: http://www.linuxcnc.org/docview/html//config_ini_homing.html
We want it to be hooked up to 2 axes of the mill and the lathe at the same time lol (just for the DRO functions)
so i need to add another axis to the sample 5i23 file
What IRC software is on the distribution disk?
* roh just glued in a ntc resistor into a heater with some '2-component-steel'
as in installed or included as a package?
gaim or some such is installed by default
some people use xchat - not sure if it's installed by default but it's packaged.
chatzilla is available as a Firefox add-on, as well as bunches of others (xchat, irssi, bitchX ...)
yeah, irssi is the one that doesn't suck :-)
xchat isnt all bad
for you text terminal people ;)
I stuck that on our one
bah use telnet
if your man enough
I've done that to mail servers
but only for testing :)
mostly the same
I was testing
then realised i actually had a message to send
I'm secure enough in my masculinity already, thanks
felt so l33t lol
funny. that reminds me of the band we just saw
"The Lost Fingers"
mozmck: yup, MP1000B
they play '80s songs as jazz-like tunes
Dallur: I thought so - I guess you wrote the configs in emc for it?
mozmck: but it does not work with the 1000C
mozmck: I just got back from seeing a bluegrass band at the coffee shop - they were fun to watch - but could sure use a banjo player
bluegrass isn't hardly bluegrass without a banjo!
oh I didn't say they didn't have a banjo...
Dallur: I work for Tom at CandCNC. He has finally given the go ahead recently for me to get our new stuff working in emc2
mozmck: they changed the pinouts, did some multiplexing, were unwilling to share info on the new pinout so I lost interest in adding support for newer versions
cradek: I see! ;)
mozmck: that's great, so your implementing the multiplexing ?
Dallur: that is the MP3000. The MP1000C is similar to the MP1000B
mozmck: ahh sorry
The multiplexing is done and working, but I will have to write a component for the serial stuff
mozmck: there are also some additional work being done on thc, there is a rewrite to port the whole thing into a component
Where do you want me to place the files for you to look at?
the new thc is an addon card with no display, but it sends the info to the computer on the serial port
mozmck: ok, I just implemented the serial stuff in as a crutch, it wasn't a very elegant solution
Dallur: I see. That was the route I was thinking of.
I am assuming you want my HAL file and my INI files
Dallur: does it work? it looked like you were trying to read from the THC
mozmck: I had a really tough time getting signals through via the serial, don't know why but about 60% of the time the voltage settings were wrong
mozmck: I read and write, and it does work but I have to verify and retry setting the voltage until it sticks with the correct number
Dallur: with the MP1000 series you can only send a setting to the THC, not receive.
the way to see if it sticks is if the display changes to the new setting.
mozmck: i'm pretty sure you can receive, although it's been about a year since the last time I worked with it
hmmm, could have been true on the A series - not completely sure.
mozmck: If there is anything I can do to help just let me know, I'm not a good programmer but more of a jack of all trades, at least I can do some testing :)
Dallur: thanks. I will probably need help. I'm a jack of all trades too, but I do write all the software and firmware for our stuff.
I'm still learning emc though (will I ever finish that?) and will surely need help along the way.
mozmck: feel free to drop me a mail, irc or msn firstname.lastname@example.org, dallur@freenet, email@example.com
mozmck: btw, if you want to look at some things done with the mp1000 check out http://dallur.com
I would be interested in helping on the thc component if that's possible as well.
I have opened HAL and done a show sig. how do I use pastebin and where do I use it?
Hate to be dense first time for everything....
Dallur: that's pretty impressive! do you build these for sale?
jimbo655, go to http://pastebin.ca/
and paste the text in there
mozmck: BigJohnT is leading the compoment rewrite, I have not really touched it
copy / paste, which can be done using menu commands, keystrokes, or by selecting text and then middle-clicking in the editor to paste
Dallur: ok. I may chat with him about it.
mozmck: nah, I decided to build a boat, figured the proper way to build one was with a computer, built a cnc cutting table, wanted to use linux, so I took 7 years and now the boat is almost done :P
mozmck: it might not be the quickest way to build a boat but it's the most fun for sure
Dallur: :) That can be the way I do things too.
that's the gallery for the plasma cutting stuff
I think I saw that a while back!
mozmck: unfortunately neither the thc300 nor the mp1000 are really built for industrial grade HF machines, took me years to finally give up and replace my plasma cutter with a non HF model
[04:09:32] <jimbo655> http://pastebin.ca/1483605
Dallur: yes, on the main board the MM 6/07 is my signature after testing the board
mozmck: lol :)
Dallur: I think we may finally have a system that has enough isolation and filtering for HF machines.
mozmck: have you thought about connecting the sensor board with a fiber
mozmck: I know it's quite a bit more expensive but I figure if it gets rid of the HF issues it's worth it
jimbo655: so you are using input 01 for X home, and input 00 for X limits
03 for Y home, 02 for Y limits
jimbo655, are you working on the Z axis still?
Dallur: hmm, I haven't. Don't know if Tom has or not. The sensor card divides down the tip volts and that analog signal is read by the processor
05 for Z home, and 04 for Z limits
so I don't know how fiber would work
mozmck: and placing the signal processor on the board would be a bit risky
at the moment you issued the "halcmd show sig" command. the X and Y home switches were tripped, the Z was not
and the Z limit switch was tripped, but the X and Y were not
mozmck: I made a pretty good list/guidelines dealing with HF/HV issues to assist some other people with their installations (based on what I learned), I could mail it to you if you want to use it in any of your documentation (feel free to use under public domain)
Dallur: yes. that's the kind of problems we run into.
What are you loking for I can put it in trip for the Z home and do another with a trip for Z limit.
Dallur: that may be helpful.
I'm not looking for anything
you know where the machine was, I don't
mozmck: where do you want me to mail it to ?
is it reasonable that limits were tripped but home wasn't?
Dallur: Our newest thc has better isolation from everything, and the newest THC should do a much better job for HF. we will be testing it shortly
mozmck: it's just something I made when helping people getting their setups working, not complete but does provide basic info which took me a while to learn :)
[04:18:04] <jimbo655> http://pastebin.ca/1483610.
Dallur: I meant the newest THC sensor card in the second part of that last sentence...
jimbo655: something is crossed up
Zhome is false, but Zlimit is true
jimbo655, do you mean to say that that last pastebin was with the Z home switch activated?
Ok, thanks! Tom has quite a bit of knowledge on that as well - as you might imagine.
past 11 PM here, I better go...
mozmck: ok, later
[04:20:01] <jimbo655> http://pastebin.ca/1483612
Z limit tripped.
jimbo655, do you mean to say that that last pastebin was with the Z home switch activated? YES http://pastebin.ca/1483610
your limit and home switches are switched
either change the wiring or change the HAL (HAL is probably easier)
I will change HAL and try again.....
jimbo655, while you have EMC running, you can pop up a few halmeters to look at all the switch inputs
as you toggle each of them (EMC doesn't have to be in the machine on state), you will see one meter turn TRUE
SO now that my limits and home are correct. When homing if I hit the limit the i receive a limit error. Where do I go now?
the home switch should be far enough inside the limits that you don't hit it when homing
otherwise, there is no point in having a separate home switch
My home switch on the XY start at the center and go to one side. My limits sit on the outside edge. of the joints.
The home switch on this machine give you center and - and right and +
so the switch is tripped for about half of the total travel?
then it should work fine
you said "when homing, if I hit the limit I recieve a limit error".
but that shouldn't happen if homing is set up right
When I try to home the Z it goes to the limit and stops with a limit error
if you are off the home switch when you start homing, it should move toward the switch (toward the center, away from limits)
if you are already on the switch, it should move off - again, away from limits
you probably have the home search velocity set wrong - if it is positive, make it negative, if negative, make it positive
That fixed it.
hey, i think jmkasunich is cheating, it sounds like he's done this before
Most likely. Now on to bigger and badder things.
I am working on the parameters for the Z axis. I have the Heidenhain data but am unsure of the crossover to your parameters. Any help?
in hostmot2's man page for stepgen velocity-cmd Target velocity of stepper motion, in arbitrary position units
what is arbitrary position units?
BJT-Hardy: don't know, but if I write there 25 then axis is moving 1500mm/min
maybe it is axis unit?
it could possibly be better to say "user-defined units"
the units are defined by the scale you choose, in relation to the hardware that's attached
I'm trying to figure out how to scale a stepper to get rpm
however, we don't know ahed of time either what the scale it, or what the units are (ie, position, velocity, torque ...)
* SWPadnos hasn't had any coffee yet ;)
so it's position or velocity, depending on the mode
have a cup on me
but the units are still unknown (mm, inch, microns ...)
or mm/s, inch/s, ...
the stepper takes 2000 steps for one rev
for some stepper and driver combinations
for mine at least
to get RPM though, it's fairly simple
the stepgen is set in frequency, which is steps/sec
so steps / sec = steps/rev * min/sec * revs/min
min/sec is 1/60
so your scale should be 2000/60 = 33.33
sure. let me know if it works :)
yep, worked perfect S1 M3 took one minute to make a rev
now to get my encoder hooked up :) and I'll have a pseudo lathe spindle to play with threading
I did figure out that you don't want stepgen enable connected to motion.spindle-on :O
realy? why not?
cause when you do a M5 it stops without any ramp down in speed
oh, true indeed
I bet it stops pretty quickly though
really neat to watch the stepper do a spin on the table
the distance units for velocity-cmd are whatever units are established by the 'scale' setting, just like they are for position-cmd
if 'scale' establishes a scale of 1 = 1mm, then velocity-cmd=1 establishes a velocity of 1mm/sec
in this case though, BJT-Hardy wanted the units to be RPM, not units/sec
a stepper driven spindle
that was my point about the units being "arbitrary" or user-defined
then find the scape that establishes 1 position unit = 1 revolution
oh, ouch, per minute
you'll come to a bad end
spindle speed is output in RMP, isn't it?
yes but that was a mistake all along
to use that as an input to any "velocity" you have to set a "scale" that makes no sense .. a scale where 1 = 1/60 revolution, or something like that
33.3333333333333 in this case :)
but when you look at position, it'll be meaningless -- threading will give the wrong pitch, for instance.
hmmm. that's true, and brings up another question
does rotation go from 0 to 1?
do you mean the stepgen position?
no, it increases forever
it's in "full rotations" isn't it? not degrees or radians
well, in threading mode
err, spindle sync mode
it's reset to 0 at the start of a spindle-sync move
using the index-enable handshake and the index input to the encoder
that also will require additional work for a stepper-spindle
there's no reset-on-index functionality
he's going to add an encoder I think
I have an encoder attached to the stepper
in that case I guess you can ignore the "position" of the stepgen altogether
I'm just using the stepper to act as a spindle
it's a frequency generator only
so it's the encoder scaling that matters for spindle sync, not the stepgen being scaled for RPM
don't you need both scaled correctly so S50 gives me 50 rpm and the encoder feedback is correct?
[13:01:02] <BigJohnT> http://imagebin.ca/view/nHjT8ku.html
yes, they both need to be scaled correctly
but the scales are different
yea, the encoder is 2500 per rev
this is a problem with the motion controller. spindle speed output is in RPM, but feedback is in RPS
plus you have different counts/rev for the two devices :)
does the sync adjust the Z feed to match the spindle feedback?
in spindle-sync mode, yes. spindle feedback is used to control axis velocity
and it can be any combination of axes, not just Z
(at least in principle, I doubt anybody's actually done threading on the UW axis, or made sure that an A-axis move is properly synched)
* BJT-Hardy goes to get the latest
(but in practice, XZ synched moves are very well tested since they're a natural part of many threading cycles)
bbl, going to the zoo
see you later
im milling some plexiglass manually, tips to make it good?
slow spindle speed, sharp cutter
i can do up to 6000
the spindle recommends different settings for some materials
could I use setting for PC?
slow enough so as to not melt the plastic... try 100 rpm
100? that's pretty darned slow
although RPM depends on cutter size
that is pretty small
so roughly 10mm per revolution - at 1000 RPM, you'll get 10m/min (30 SFPM)
The_Ball1 is now known as The_Ball
that should be OK, you might be able to go up to 2000 or 3000
the important part is SHARP, you need to be cutting, not rubbing, or friction will melt the plastic and make a mess
choose your feed so you are taking at least 0.002" per flute
0.050mm per flute I think that is...
so a 2 flute cutter at 2000 RPM is 4000 flutes per minute * 0.050mm/flute is 200mm/min
you might be able to feed faster, maybe 0.1mm/flute - it all depends on your machine, workpiece, and cutter
took a hipshot
he is milling manually so feed rate will not be so easy to figure
I use lots of air on the cutter and watch for chips and not little balls of plastic on my manual mill
if milling manually, just make sure you feed fast enough that you are getting nice thick chips, not thin flakes or dust or melt
it was nice chips =)
big and nice
only issue, im milling on my desk :P
Get Smart "Dome of Silence" :)
Good Morning..... :) Still looking at the Homing. during homing I receive a hit limit in homing state error and My favorite joint 2 on limit switch error.
Taht is state 16
what do you say, do you need limitswitches or its just a "blingbling" =)
Hi guys, I was wondering if it is possible to compile the simulation mode of EMC2 to run under windows, and how I would go about doing that.
Danosaur, makes little sense, wont be easy at all, just use the live CD
you could try
What are the major issues with doing it?
Yes I need limit switches. Is there a way to modify the Homing routine? Is it done inside of ladder? What are the files that I access?
Danosaur, dont know, not tried, dont remember anyone talking about trying in the two years Ive been watching the project
Danosaur, iirc someone did remote to a Linux box from windows
Hmmmm... that's probably not a good sign.
windows is not a good sign where hardware control is done
You can use a vm
I compiled a version of Emc1 a long time ago on doze.
Maybe 4-5 years ago. I don't think it would be worth the trouble now.
How deep into the motion control code does the simulator need?
tomp is now known as tom3p
I guess libraries and environment are a bigger issue
For Emc2 the multiplatform support has been dropped, so it would be a huge pain.
Try installing portable Ubuntu
That works as a win app.
Ok. I'll give that a shot for now I guess. Was hoping for a different answer. :-)
why do you think windows should be supported
and do you realise why it is not (realtime control)
I do realize why it is not. It is because it is the most commonly used and most convenient system. It would require external hardware to handle the RT tasks.
I like the idea of linux too, but it just isn't widely used enough.
heh, its used more than you think
linux is used more than Fanuc is more direct analogy
so much of the web is served on linux
All of the file servers That I put in businesses are NOTt running windows.......:)
For people with highly technical backgrounds, or in the IT world, yes.
the user stuff is catching up reasonably well now
But does someone setting up a CNC mill in their garage want to learn a new OS and have to mess with transferring back and forth?
and ... i gotta say, regular linux is not good for realtime, and there are pretty good rt extensions for microsoft o/s's, (expensive extensions )
and as a lot like firefox and open office run on both platforms the swap is easy for some
I personally like linux, and agree that it is fairly usable now. But is it widely used by the average person running CNC equipment?
i agree that a great cad is not free on liux, BUT great cad is available on linux for money, making a pure linux environment convenient ( just not free )
the average person runing cnc equip uses neither linux nor microsoft
haha, yes, on his CNC machine. But when he does use a PC, what OS does he know?
the average person running cnc equip uses closed source single application program, he cant get email, see web, play sone, write letter
then we leave the average person arena :) and it is personal preference, personal pocketbook that directs the person
and, what he has heard of and what he's willing to try
Most embeded and automation systems including CNC are running dedicated code for there process and theirs only. windows, Linux, CPM, etc. are only there to make easy for the human to use......... At the cost of overhead and direct access to the hardware.
Danosaur: i understand your viewpoint, i hate to have to goto windows... that means we both hate to swap. (we agree:)
I live on both for different applications
yes, i do in some cases too.
lets change topic, what do you guys use to modell and cam in linux
frallzor, HeeksCAD when we get it done
I still havent found a nice combo to use
most doesnt seem like solidworksmodells
I am not using Linux.. I have purchased Rhino cad3d and mad cam.
us poor folks cannot go that route
Thanks for the chat guys. Later!
poor folks can pirate? :P
I went to school....... Again.........
freenode users do not pirate
sure they do, no matter how small the "crime" is most have still pirated, mp3 etc etc =)
Are the routines for the Homing sequence done in ladder?
saying that nowadays is like saying that your farts doesnt smell but that wasnt the topic :P cam is
is there some nice cam for win that is free?
cant wait to get my little thing up and running
anyone here using a gecko g540?
a couple do
wondering if you get the cable to connect to a pc with it =)
DB25M-DB25M isnt easy to find
get a M to F and use a gender changer
pmdx puts the centronics connector on their boards, so you can use any normal printer cable -- very smart IMO
wonder why gecko is so stupid to put a femaleconnector on theirs
cradek: That's even harder to find
Jymmm not really
I find them everywhere =)
yeah I doubt that
standard type 57 never aproblem
When was the last time you saw a centronix connector on a modern printer?
when was the last time you saw a DB25 on a modern printer?
I dont I see them on modems
centronics is a recent name for an old standard connector
modem = wrong cable
the db25-db25 straight through cable is hardly ever used in normal computing, only for printer switchboxes and oddball stuff like that
the db25-centronics printer cable is used with every parallel printer.
centronics-> real name is Amphenol type 57 centronics refers to number of pins and wiring
pardon my commoner usage
still wondering if you get the cable with the G540 :P anyonw know?
frallzor: surely you can order it from newegg or the like?
sweden - I won't have any useful advice then.
cradek, all the catalogues use centronics even for other sizes now :((
pedantry hurts, doesn't it (and I would know)
and seen them called IEEE488
which is only 24 pin
jymm thats serial nonononono
well thats what I need =)
well it says "serial or parallel applications" and "straight through"
so maybe it's fine, just poorly labeled
[19:50:49] <Jymmm> http://www.pcconnection.com/IPA/Shop/Product/Detail.htm?sku=131200
Here ya go even says all 25 are wired
but I still live in sweden ;)
frallzor, so google your local suppliers
oh it seems it needs to be parallell
oh, and digikey are desperate for customers, so they have free shipping for an order >60eur ...
couldnt find, and i wont shop there again due to the rape of regular ppl =)
insane shipping for non-companies
no clue what this says.... https://www1.elfa.se/elfa~se_sv/catalog/getAtpInfo.do?display_scenario=query
i think everyone in here can say what it says ;)
maybe RS electronics in Sweden (not radio shack)
afaik they dont sell to non-companies?
well, then I'll let you find your sweden cable
frallzor: i have a male to male dsub 25 cable
great, ship it with the e-stop? =)
that's what i had in mind
[20:00:48] <tom3p> http://www.rsonline.se
or, make one
ill wait until someone with G540 can answer if they got a cable with it =)
that seems onlikely
got one with my chinese driver =(
but its m-f
female connector on the g540 doesn't make much sense at all
extremely stupid if they dont supply a cable
stupid is not a word I would use to describe Marriss
"not quite thoughtrough" then
Does anyone know if I can run earth ground through the meter box? (running it up the same conduit that the main feed is coming in)
How are they to know what length is needed... 3ft, 12ft
this is their first parallel-connected thing right?
Even printers dont come with a cable
but they use a cable you can allmost get at your local supermarket
Yeah, I'd love to walk into 7-11 and pick up a 400 ozin stepper motor
you talked about cables
buy 2 cables at supermart, cut in half, make what you like
read the manual, implies you dont get one "5) PARALLEL PORT CABLE: Use a parallel port cable to connect the G540 to the PC. The G540 end of the cable must be a male DB25 connector."
but the end implies you do have to get one? =)
not really hard to connect male-male =)
of course mari
of course marriss is not stupid
but i see little point in putting a female sub25 on a device clearly intended to be connected to a parallel port
***** db25 cables all genders http://www.winfordeng.com/products/ext25.php
finally found a store in sweden that sells them
my G540 did not come with a cable
then I know =)
skunkworks: I ran my ground wire from driven ground, through the meter box, and into the main panel. Bonded to the meter box, the main panel, and the cold water pipe. Used a separate opening in the meter box - the power company came along later and brought in the feed.

i love directions like that
"BUT WAIT, FIRST,"
Every time I *DO* follow the instructions, I screw something up.
Ok, they say dont get on a plane within 24-48 after diving. Now, What about parachuting from a plane into the ocean and then diving?
the problem arises when you're diving, and you need to be rescued by helicopter and then transfered to plane
alex_joni: when did you get a BB?
Is there an offset to control the 0 volt in the ini file. My Z wants to creep when I am homing X
jimbo655: i dunno if in ini but thats a logical place. also, null the amp ( short the analog input to insure its 0 and to clamp all noise, then adjust any offset in the amp so no voltage is applied to motor or observe no motion.. this is all open loop outside of emc control )
null= no inputs causes no output
good night all
alex_joni: what's his name?
anyone got the best tip for cam when using solidworks? it may cost as long it isnt superexpensive
yes, name a good cam-software that isnt superexpensive and got good support for solid =)
camworks intergrates into SW for CAM, so does solidacm
but most campackages can take in parasolids etc
camworks starts at around 3k for 3 axis basic mill, so does solidcam
well that is pretty superexpensive for a hobbymiller :P
alway to 15-19k for 5axis, mill turn, sub spindle lath etc
lets say a good choice for learning then
depends how much u can screw a reseller down to, if u already have a cam package they may offer a trade out deal ontop
solidcam do a demo on there site, its pritty much full version minus abilituy to do any post processing. save cam data, but u can make tool paths, sim it etc
solidcam demo page http://www.solidcam.com/downloads_overview_en,2712.html
ill guess ill check tuts and so on for that then
they all have a very steep learning curve
what is it you are looking to do
learn a pretty decent cam-software so I can use my futuremill
if u want a cheap package look at onecnc, but they are getting abit pricy now days and found there software abit limiting for complex jobs
I want to be able to do some complex things so I guess ill look into solidcam then
dont get me wrong onecnc can do complex can 4 axis, 5th is 4 axis with 5 as index
but its when u make part mods/changes in SW things get messy
we have looked at alot over the years for doing solids, we mainly do mold & Die making, and proto type coustomers parts first from solid also.
so you recommend onecnc?
for what u want to do it may fit very nicly for you, if u want to make 1 offs or low batch numbers,
mostly for cibatoolmodels
it starts around 1.8/2k i belive for 3 axis milling
they have a demo?
dont any more unless they do i not been on there for awhie
they were at the CNC workshop a couple of years ago. I think they said they were going to add an EMC post
some times u can pick up a old copy on ebay version out of date etc for quite cheap,
I don't know if they ever did
but still. 2k is pretty much for a student =/
as with them there is no yearly fee, just pay for software thats it, when u want a new update u by the next package level for a price
or well, at least now it is =)
where you study they not do a student version for you to use?
no, not when studying this
we will get solidworks but nothing for cam
for EMC post i find a generic fanuc post will work quite well on EMC only needing very few changes to work
isnt there something like emc2 for cam for windows? =)
no, but the WeberSys "Synergy" CAD/CAM package for Linux is like $89 for the basic version
I think that includes 2.5D or possibly 3D CAM
noone does studentversion for this like autodesk does for most of their software?
and there is a free downloadable demo
some probably do
TurboCAD/CAM works OK too, on Windows
I haven't tried it on WINE, but I probably should
CAM is one of them things i find
i know big companys that still do not use cam properly or to its fullist all manual programming at machine
mainly becasue of time needed to learn it, and cost of training etc
CAM has to be really smart to be better than someone who knows how to read a print
but for complex 3D stuff, it's the only way to go
ill try Synergy CAD/CAM
a cam can only follow its wizards to do a task, camworks u can coustomize them wizards to max if u have the time, not many let you do that

. Segmentation fault.
jimbo655, did you change the intro image?
Once in a while it happens on startup but If i leave EMC2 up it will always happen within 24 hours
so if you leave EMC2 running, there will be a segfault?
or if you leave EMC2 running, then you get a segfault in popimage when you restart EMC2?
I am being stupid. don't listen to me for a few minutes
SWPadnos: wouldn't that imply... oh nm... HAppy 4th!!!
oh hey Jymmm
check out the new Atmel AT32UC3L microcontrollers
[23:02:20] <SWPadnos> http://www.atmel.com/products/avr32/uc3/uc3_22.asp?family_id=682
the really interesting thing about them is that they can PWM basically every I/O bit
Jymmm: Don't have instructions - made a sketch, got some wood...
[23:03:00] <DaViruz> http://www.youtube.com/watch?v=Ge9_Qbd09zU&feature=channel_page
heh, love the wingnut :)
nice small slitting saw, got to get one of those
SWPadnos: Oh man... crypto storage, nice!!!!
it's the PWMs that are more interesting
I wouldn't trust microcontroller crypto
SWPadnos: Well, I was gonna say git it 120 days till someone does =)
yeah, the chip runs at 75 MHz or something internally
using a 10-12 Mz crystal or internal resonator
how long is one instruction cycle?
except for some branches and jumps
it's very much like an AVR, only 32 bits (hence the name AVR32 ;) )
thx, i need better edm oscillator, the pic 16f84 is limited even at 20Mhz
divided by 4 again
so only 5 MIPS
an 8-bit AVR at 12-16 MHz would probably be plenty
math is a lot faster with the AVR instruction set than with a PIC
thx, no real math needed only decs & compares were used, polling 2 ports for new on & off times
I'm just talking about adding, subtracting and comparing mylti-byte values :)
not floating point
though I do have some very fast multibyte multiply na ddivide routines as well
... and divide ...
i'm outta here! i got < .0003 tir on a 7 axis machine, i hope it repeats after sitting all night ( make that 6, the W is downright wobbly, like .0012" )
thx for the suggestion
jimbo655, the segfaults you're getting are in several programs (emcsh and axis from that log)
please run a memory test for at least 24 hours
Can I just replace the memory?
you shouldn't fix anything until you know it's broken
and you only iknow you have really fixed the problem if you can repeatably trigger it before attempting a fix, then repeatably not see it when doing the same test that triggered it before
so the answer is yes, you can just replace the memory, but you won't know for sure that the problem is fixed if it appears to go away
I will run a memory test..... You just want me gone for 24 hours..... :)
While I have you handy how do I change the homing routines?
with the ini setttings
check the manual section on homing. it has diagrams and explanatioins of what they mean, and I don't know offhand
I will look again.....
